MANTON, Circuit Judge.
A jury convicted Marvin Berkowitz of two counts of obstruction of justice, 18 U.S.C. § 1503, and one count of stealing government property, 18 U.S.C. § 641. Berkowitz appeals, contending that the district court erred by denying his motion to suppress evidence, that certain actions by the district court deprived him of the assistance of counsel, that when he did have counsel he provided ineffective assistance, and that the district court improperly sentenced him. 712 F.Supp. 707. We reject Berkowitz’s assistance of counsel and sentencing claims, but remand for an eviden-tiary hearing on his motion to suppress.
I.
A grand jury indicted Berkowitz (along with others) in April 1988, alleging numerous counts of tax fraud, mail fraud, and obstruction of justice centering around the sales of allegedly fraudulent tax shelters (the “tax fraud case”). During its investigation of Berkowitz's activities, an investigation that began in 1983, the government accumulated almost 18,000 documents, plus other exhibits, all of which filled more than 50 boxes.
The government stored this evidence in a file room in a secured area of the United States Attorney’s (USA) office in Chicago, and in June 1988 established a procedure to allow the defendants in the tax fraud case to inspect, examine, and photocopy those *1379documents that were discoverable to prepare for trial. Boxes that were available for immediate inspection were marked with a “Y” or the word “Yes.” However, some documents such as witness statements, internal memoranda, and work product were either not discoverable or, under Fed.R. Crim.P. 16, Northern District of Illinois Local Rule 2.04, or the Jencks Act, 18 U.S.C. § 3500, were not discoverable until a later date. The government kept these documents in boxes marked with an “N” or the word “No.” To gain access to the documents, a defendant or his attorney had to make an appointment with IRS Special Agent Merle Shearer. On the appointed date, either Shearer or IRS Special Agent Frank Calabrese would escort the defendant or his attorney to the file room containing the documents.
Of the defendants in the tax fraud case, Berkowitz showed the keenest interest in examining the government’s documents and exhibits; in fact, he was the only defendant to review documents personally at the USA’s office. Between July and October 1988, Berkowitz arranged to examine the documents and exhibits 17 times. According to Shearer, the first time he met with Berkowitz and his attorney he escorted them to the file room, explained the procedures to them, showed them which documents were and were not available to inspect, and showed them a photocopier they could use.
Berkowitz, however, turned out to be not particularly scrupulous about following the procedure established for inspecting the documents. On August 17, Calabrese escorted Berkowitz from the file room to the elevators in the reception area of the USA’s office after a reviewing session. Calabrese returned to the file room to retrieve his briefcase, went back to the elevators, and found Berkowitz gone. When Calabrese returned to the secured area of the USA’s offices (the elevators being in an unsecured area) he found Berkowitz standing in a stall in the men’s washroom, apparently hiding. Berkowitz had no permission to return to the secured area.
On October 5, after a reviewing session, Calabrese escorted Berkowitz and his attorney to the first floor of the Dirksen Federal Building, in which the USA’s office is located. A little later that day, Assistant United States Attorney William Cook, who was prosecuting the tax fraud case, saw Berkowitz leave the men’s bathroom in the secured area of the USA’s office and walk to the file room unescorted. After trying to find Calabrese, Cook confronted Ber-kowitz and asked where Calabrese was. Berkowitz said he was in the men’s room; he was not. Cook then went back to the file room, and asked Berkowitz what he was doing. Berkowitz told Cook that he had left something in the file room, and started moving “No” boxes around. Cook told Berkowitz those boxes were off-limits, and Berkowitz left.
Judge Marshall, who was presiding over the tax fraud case, ordered the government to produce by November 15, 1988, a list of the evidence it intended to present at trial and the names of and any background material concerning witnesses it intended to call. To comply with this deadline, Shearer began to review the documents on October 26. At that time, Shearer discovered that about twelve of the fifty boxes of evidence were missing. An investigation revealed that none of the missing documents had been misplaced in the USA’s office. One box was found on the Dirksen Building’s seventh floor, near a freight elevator accessible both from a public area on the seventh floor and from the secured area of the USA’s office.
Cook advised Berkowitz’s co-defendants’ attorneys that documents were missing, and gave them an inventory of the missing documents. Cook learned on November 4 that documents had been delivered to two attorneys’ offices. That same day, receptionists for each of the attorneys identified Berkowitz’s picture from a photographic array as the man who had delivered the documents.
The IRS agents and Cook put two and two together and concluded Berkowitz had stolen the missing documents. On November 7, Shearer, Calabrese, and other IRS *1380agents set out to Berkowitz’s home to arrest him. But despite the knowledge they had (knowledge that indisputably amounted to probable cause to arrest Berkowitz), and for reasons not apparent to us, the agents did not bother to obtain an arrest warrant.
The parties agree that when the agents arrived at the house, Shearer knocked on the door and Berkowitz opened the door to answer. At this point, their stories diverge. According to Shearer, after Ber-kowitz opened the front door Shearer immediately told him he was under arrest. Berkowitz did not resist or attempt to close the door; he simply asked if he could have his sports coat. An agent retrieved the coat, which was draped over a chair inside Berkowitz’s house. According to Berkow-itz, however, immediately after the door was opened, Shearer stepped into the house and then told Berkowitz he was under arrest. As the government presents things, the arrest preceded the agents’ entry; as Berkowitz tells it, the entry preceded the arrest.
After arresting Berkowitz, Shearer asked him if there was anything he wanted. Berkowitz responded that his keys were in his office. Berkowitz started walking toward his office, and Shearer and Calabrese followed him. According to Shearer, he noticed on top of a desk in Berkowitz’s office and in an alcove area under the desk numerous files and other documents (including original tax returns) that he recognized as some of the files and documents missing from the USA's office. Shearer said he was able to recognize those files and documents, in part, because his own handwriting was on some of the files. Shearer seized some of the records, and took Berkowitz away.
That day, the government obtained a warrant to search Berkowitz’s home; the next day, the government obtained a warrant to search a safe in Berkowitz’s house. Those searches turned up numerous documents and evidence that had been missing, including checks that had been torn up and thrown in a wastebasket. But despite those searches, the government never recovered the vast majority of missing documents.
A grand jury indicted Berkowitz, charging him with two counts of obstruction of justice, 18 U.S.C. § 1503, and one count of stealing government property, 18 U.S.C. § 641. Before trial, Berkowitz’s appointed attorney, William Huyck, filed a motion to suppress the evidence found in Berkowitz’s home during his arrest and the subsequent searches. Judge Bua, who presided over this case, denied the motion without holding an evidentiary hearing.
About two weeks before trial, Huyck asked the district court to continue the trial because he had had insufficient time before trial to review documents in the government’s possession. Judge Bua denied the motion but urged the government to accommodate Huyck’s request to review the documents. The next day, Huyck moved to withdraw so that Berkowitz could retain a new attorney. However, since the new attorney could not be ready to try the case on the date set for trial, the judge denied this motion also.
On the first day of trial, after the jury was selected and immediately before the opening statements, Berkowitz told the court that he wanted to represent himself. Judge Bua asked Berkowitz whether he was insisting on his constitutional right to represent himself. Berkowitz responded that he wanted to “waive the right to counsel, but ... not waive the right to have counsel”; in other words, he wanted to try the case himself but have standby counsel. Without inquiring any further into Berkow-itz’s understanding of what trying a case entailed or the disadvantages he might face by trying the case himself, the judge granted Berkowitz’s requests, declaring that “based on the little I know about your background [exactly what the judge knew does not appear in the record] ... if any defendant is competent to represent himself, it is you.... ”
At trial, Berkowitz testified on his own behalf (with Huyck asking the questions), and admitted taking government documents out of the USA’s office. However, this admission was necessary within the *1381context of Berkowitz’s defense, which was to deny (or at least create doubt about) his intent to deprive the government of the documents or to obstruct justice. Thus, Berkowitz testified that he did not intend to obstruct the government’s prosecution of his case. He took documents only because he believed that the government was withholding evidence and treating him unfairly in the tax fraud case. He testified that he intended only to copy and return the documents, and that he did in fact return many of the documents he took after copying them. He also testified that a number of the documents found at the time of his arrest were his own, not the government’s, thus casting (or attempting to cast) doubt on the government’s contention about how many documents he took. Ber-kowitz’s cross-examinations of the government’s witnesses (Shearer and Cook) followed this same theme.
In the end, though, the jury did not accept Berkowitz’s defense, and convicted him of all three counts charged. The district court sentenced Berkowitz under the sentencing guidelines to sixty-three months imprisonment, which represented an upward departure from the sentencing guideline range that would have applied based on the severity of Berkowitz’s offenses and his criminal history score.
II. Assistance of Counsel
Berkowitz contends that we must reverse his convictions because he received ineffective assistance of counsel. According to Berkowitz, Huyck was ineffective because he failed to examine documents. Moreover, Berkowitz says that the district court effectively deprived him of counsel by denying his motion to continue the trial date and by failing to admonish him properly about the pitfalls of proceeding pro se.

A. Denial of Continuance.

We first consider Berkowitz’s contention that the district judge denied him effective assistance of counsel by denying Huyck’s motion to continue the trial date. According to Berkowitz, denying the continuance left Huyck without adequate time to examine the government’s documents before trial. This lack of preparation, Ber-kowitz says, led to his decision to proceed pro se.
The Sixth Amendment provides that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to have the Assistance of Counsel for his defense.” Normally, to show that his Sixth Amendment right to counsel has been violated, a defendant must show that deficiencies in counsel’s conduct (such as poor preparation) actually prejudiced him by casting doubt on the reliability of the trial’s outcome. See United States v. Cronic, 466 U.S. 648, 655-59, 104 S.Ct. 2039, 2044-47, 80 L.Ed.2d 657 (1984); Strickland v. Washington, 466 U.S. 668, 691-96, 104 S.Ct. 2052, 2066-69, 80 L.Ed.2d 674 (1984). However, in some cases where the defendant has no counsel at all, or an action by the prosecution or the trial court so hamstrings counsel as to effectively prevent counsel from actually assisting the defendant, prejudice is presumed and constitutional error is present without the defendant having to show actual prejudice. See, e.g., the cases cited in Cronic, 466 U.S. at 659 n. 25, 104 S.Ct. at 2047 n. 25. Berkowitz seems to be arguing that the trial judge’s denial of a continuance hampered Huyck so much (by denying him adequate time to prepare) that the denial of the continuance prevented Huyck from actually assisting Berkowitz. We disagree with this characterization.
Trial judges have broad discretion in scheduling trials. Consequently, “only an unreasoning and arbitrary ‘insistence upon expeditiousness in the face of a justifiable request for delay’ violates the right to assistance of counsel.” Morris v. Slappy, 461 U.S. 1, 11-12, 103 S.Ct. 1610, 1616-17, 75 L.Ed.2d 610 (1983). The district judge in this case did not abuse his discretion in denying the continuance motion, so that denial did not deprive Berkowitz of counsel’s assistance. Huyck had almost two months (from November 14, 1988, the date of his appointment as counsel, to January 3, 1989, the trial date) to prepare for trial. He had almost two weeks from the time the trial judge denied the continuance to *1382the trial date. The government provided Huyck and Berkowitz with a detailed inventory of the documents it claimed were missing, and made the remaining documents available for inspection at any time. The issues in the case — essentially, whether Berkowitz stole and destroyed documents, and whether Berkowitz intended to obstruct justice — were not complex. In short, the trial judge acted well within his discretion in denying a continuance, and that denial, by itself, did not deprive Ber-kowitz of Huyck’s effective assistance. Cf. United States v. Blandina, 895 F.2d 293, 297 (7th Cir.1989); United States v. Studley, 892 F.2d 518, 521-23 (7th Cir.1989).

B. Failure to Examine Documents.

This brings us to Berkowitz’s second contention concerning effective assistance of counsel: that Huyck failed to provide him effective assistance because he failed to examine documents. Adequate pretrial preparation, including the examination of documents, is essential to properly represent a criminal defendant. But how much preparation is enough (like the numerous other decisions an attorney must make in the course of representation) is a matter of professional judgment. The attorney’s judgment is entitled to deference; thus, for Berkowitz to show Huyck’s performance was deficient, he must overcome a “strong presumption that [Huyck’s] conduct [fell] within the wide range of reasonable professional assistance” and show that Huyck’s pretrial preparation fell below “an objective standard of reasonableness” based on “prevailing professional norms.” Strickland, 466 U.S. at 687-91,104 S.Ct. at 2064-66; see also United States v. Weaver, 882 F.2d 1128, 1138 (7th Cir.1989). Moreover, even if Huyck’s pretrial preparation was objectively deficient, Berkowitz must show that lack of preparation prejudiced him in the sense that a reasonable probability exists that “but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Strickland, 466 U.S. at 694, 104 S.Ct. at 2068.
Since we presume that Huyck’s performance fell within the range of reasonable professional assistance, it is Berkowitz’s task to show otherwise. The only evidence Berkowitz cites concerning Huyck’s preparation is a statement in a new trial motion, prepared by Huyck, that he did not seek copies of the records the government had seized. But the motion states only that Huyck did not ask for copies; it does not state that Huyck did not inspect the government exhibits. Furthermore, there are indications in the record that Huyck spent considerable time reviewing records and preparing for trial. The evidence in the record is insufficient for Berkowitz to overcome the presumption that Huyck’s preparation was reasonable.
Even if Huyck’s preparation was deficient, Berkowitz has failed to show prejudice from this deficiency. Berkowitz says that because Huyck did not review all the government’s documents, he could not show that the government never possessed many of the documents that Berkowitz allegedly stole. Berkowitz also argues that without knowing what documents the government had left after Berkowitz’s theft, Huyck could not challenge the government’s assertion that the loss of the stolen documents adversely affected the government’s ability to try the tax fraud case. Neither of these complaints are sufficient to establish prejudice. First, the evidence that Berkowitz did steal and destroy at least some documents was overwhelming: Berkowitz himself admitted taking documents, and the government recovered torn checks that had been stolen from a wastebasket in Berkowitz’s home. Second, obstruction of justice requires the government to show only that a defendant “endeavor[ed] to impede a prosecution, not that he actually impeded the prosecution. See 18 U.S.C. § 1503. The key question at trial was Berkowitz’s intent, not whether he actually impeded the tax fraud prosecution. The fact that Berkowitz actually did destroy documents and the fact that he had government documents in his house several weeks after his last visit to the USA’s office raise a strong inference that Ber-kowitz intended to impede the tax fraud case. Why else would he keep or destroy government documents? During trial, Ber-*1383kowitz was able to identify numerous documents that the government claimed were stolen that had already been in his possession. But given the overwhelming evidence that Berkowitz did steal and destroy some documents, it is not reasonably probable that showing that some other documents the government claimed were stolen were not would have changed the jury’s verdict.
C. Waiver of Counsel.
Berkowitz’s third, and potentially most substantial claim concerning assistance of counsel is his claim that the district court failed to properly admonish him about the pitfalls of representing himself. In Faretta v. California, 422 U.S. 806, 95 S.Ct. 2525, 45 L.Ed.2d 562 (1975), the Supreme Court held that criminal defendants have a constitutional right to self-representation. But before permitting a defendant to exercise this right, the trial judge must ensure that the defendant has knowingly and voluntarily waived his Sixth Amendment right to counsel. To do this, the judge should advise the defendant about and try to ensure he understands the benefits associated with the right to counsel, the pitfalls of self-representation, and the fact that it is unwise for one not trained in the law to try to represent himself. See United, States v. Moya-Gomez, 860 F.2d 706, 731-32 (7th Cir.1988). In United States v. Mitchell, 788 F.2d 1232, 1236 n. 3 (7th Cir.1986), we stated that the district judge should engage in
a thorough and extensive inquiry of [defendant] by asking [him] his age and degree of education; informing him of the crimes with which he was charged and the maximum possible sentences; determining that [he] understands] the nature of the charges; ascertaining that he ha[s] copies of the Federal Rules of Evidence and the Federal Rules of Civil Procedure and instructing him to read them and to abide by them, whether read or not; and telling [him] that he would be expected to conduct himself in accordance with those rules.
See also Moya-Gomez, 860 F.2d at 732. An excellent guideline for the appropriate inquiry a district judge should conduct when a defendant announces he wants to represent himself, and a guideline consistent with our pronouncements in Mitchell and Moya-Gomez, is contained in 1 Bench Book for United States District Judges § 1.02 (3d ed.1986), which is reproduced as an appendix to the opinion in United States v. McDowell, 814 F.2d 245, 251-52 (6th Cir.1987).
It is important that district judges conduct a proper inquiry of and convey the necessary information to a defendant who wishes to represent himself. When the Supreme Court in Faretta announced the right to self-representation it placed trial judges between a rock and hard place. Whether the district court honors or denies the defendant’s request to represent himself, the defendant is likely to appeal if he loses at trial. The appeal will almost inevitably revolve around whether or not the defendant was fully aware of his right to counsel, the benefits he receives because of that right, and the pitfalls of going alone. By conducting a formal inquiry such as the one set out in the District Judge’s Bench Book, the judge will insulate the judgment from this type of attack. The trial judge is in the best position to assess whether a defendant has knowingly and voluntarily waived counsel. This court will most likely uphold the trial judge’s decision to honor or deny the defendant’s request to represent himself where the judge has made the proper inquiries and conveyed the proper information, and reaches a reasoned conclusion about the defendant’s understanding of his rights and the voluntariness of his decision. We realize that such inquiries take time. But the few minutes a proper Faretta inquiry normally would take is a worthwhile alternative to a new trial.
It is clear the district judge in this case did not conduct a proper inquiry concerning Berkowitz’s waiver of counsel. The judge did not inform Berkowitz of the benefits of having counsel or the pitfalls of representing himself. While the judge did recite to Berkowitz the old saw that “a lawyer [who] represents himself ... has a fool for a client,” this hardly constitutes the kind of *1384searching inquiry we spoke of in Mitchell and Moya-Gomez. But on appeal Berkow-itz makes little of this shortcoming. He raised the Faretta issue as almost an afterthought, devoting only one sentence in his brief to this issue, not even attempting to explain what a proper inquiry should entail, and citing no pertinent authority to support his “argument.” His nonchalant treatment of the omission on appeal leads us to conclude he considers the inquiry of little consequence. We repeatedly have made clear that perfunctory and undeveloped arguments, and arguments that are unsupported by pertinent authority, are waived (even where those arguments raise constitutional issues). See, e.g., United States v. Brown, 899 F.2d 677, 679 n. 1 (7th Cir.1990); United States v. Petitjean, 888 F.2d 1341, 1349 (7th Cir.1989); United States v. Williams, 877 F.2d 516, 518-19 (7th Cir.1989); Fed.R.App.P. 28(a)(4).
Given the complete lack of inquiry by the district judge, we might be willing to forgive Berkowitz’s waiver but for one point: a failure to make a proper inquiry of a defendant who asks to represent himself, by itself, is not necessarily reversible error. The real question when a criminal defendant waives counsel is not the quality of the trial judge’s inquiry; rather, it is whether the defendant knowingly and voluntarily waived his right to counsel. Thus, if a formal inquiry is deficient, or even lacking, we will not reverse the defendant’s conviction if the record as a whole demonstrates the defendant knowingly and voluntarily waived his right to counsel. See Moya-Gomez, 860 F.2d at 733 (citing cases).
Berkowitz did not argue in his opening brief how the record as a whole does not show that his waiver of counsel was not knowing and voluntary. In fact, he did not mention this necessary analysis of the record or even assert that his waiver was not knowing and voluntary. He cited no pertinent authority on the point. The government in its response brief thoroughly analyzed the record to attempt to demonstrate that Berkowitz’s waiver of counsel was knowing and voluntary, and cited authority to support its legal analysis. Despite the government’s argument, Berkow-itz ignored the waiver of counsel issue in his reply brief and at oral argument, making no attempt to refute the government’s analysis either legally or factually.
A party urging us to reverse a district court’s judgment has an obligation to argue why we should reverse that judgment, and to cite appropriate authority to support that argument. See Brown, 899 F.2d at 679 n. 1; see also Beard v. Whitley County REMC, 840 F.2d 405, 408-09 (7th Cir.1988). “The premise of our adversarial system is that appellate courts do not sit as self-directed boards of legal inquiry and research, but essentially as arbiters of legal questions presented and argued by the parties before them.” Carducci v. Regan, 714 F.2d 171, 177 (D.C.Cir.1983) (Scalia, J.). It is not this court’s responsibility to research and construct the parties’ arguments. Williams, 877 F.2d at 518; Beard, 840 F.2d at 408-09. Since Berkowitz has chosen not to argue that his waiver of counsel was not knowing and voluntary, even despite the government’s argument that it was, he has waived the issue.
In any event, there are several indications in the record that Berkowitz knowingly and voluntarily waived his right to counsel. Berkowitz is a college graduate. He knew he had the right to be represented by counsel, and affirmatively asked to represent himself. He understood the distinction between having counsel and being represented by counsel; while he asked to conduct the trial himself, he insisted that Huyck stay in the case as standby counsel. Not only did Berkowitz actively participate in the discovery process of the tax fraud case, but he also had represented himself in a prior civil action, so he had prior experience with judicial procedures. Moreover, Berkowitz’s trial conduct demonstrated a fairly sophisticated understanding of the judicial process. Berkowitz made several evidentiary objections that the district court sustained. He also was able to cross-examine the government’s witnesses on the subtleties of the best evidence rule, Northern District of Illinois Local Rule 2.04, Fed. R.Crim.P. 16, and the Jencks Act. While *1385the district judge should have conducted a much more searching inquiry concerning Berkowitz’s waiver of counsel, the facts we have noted are enough to demonstrate that Berkowitz’s waiver was knowing and voluntary, at least absent any assertion by Berkowitz otherwise.
III. Arrest and Search
Berkowitz next asserts that the district court should have suppressed the evidence found in his home during his warrantless arrest and during the searches of his home the following day. (According to Berkow-itz, information derived from the documents seized at the time of arrest was used in the affidavit Shearer submitted to obtain a search warrant; the government does not — at least now — contest this assertion.). Berkowitz posits three reasons why the district judge should have suppressed this evidence. First, Berkowitz argues that Shearer and other IRS agents illegally arrested him in his home without a warrant. Second, Berkowitz argues that even if the arrest was lawful, IRS agents had no right to follow him into his office, where they found the documents. Finally, Ber-kowitz argues that even if the agents had a right to be in his office, the documents Shearer seized were not seizable under the plain view exception to the warrant requirement because it was not readily apparent that those documents were among the ones Berkowitz stole.

A. Arrest at Berkowitz’s Home.

The district judge denied the suppression motion without holding an evidentiary hearing because he found that Berkowitz had “failed to identify any factual dispute relevant to the disposition of the motion.” But there was, as we have seen, a factual dispute concerning Berkowitz's arrest. The government claimed (supported by an affidavit by Shearer) that the IRS agents asserted their authority to arrest before entering Berkowitz’s home, and that Berkowitz did not resist their authority; only after this did the agents enter the home to complete the arrest. On the other hand, Berkowitz claimed (supported by his own affidavit) that Shearer and the other IRS agents entered his home before informing him he was under arrest.
Despite this factual conflict, the district court was obliged to hold a hearing only if the difference in facts is material, that is, only if the disputed fact makes a difference in the outcome. See United States v. Rollins, 862 F.2d 1282, 1291 (7th Cir.1988); Nechy v. United States, 665 F.2d 775, 776 (7th Cir.1981); see also United States v. Sophie, 900 F.2d 1064, 1071-72 (7th Cir.1990). Whether the factual conflict here is material depends on whether the arrest’s legality differs under the different versions of facts. If the arrest was legal under either version of the facts, we must affirm the district court; if the arrest was illegal under either version of the facts, we must reverse. Only if the arrest was legal under the government’s facts but illegal under Berkowitz’s must we remand for an eviden-tiary hearing.
Generally, police may not enter a person’s home to arrest that person without an arrest warrant, unless exigent circumstances exist. Payton v. New York, 445 U.S. 573, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980); see also Minnesota v. Olson, — U.S. -, 110 S.Ct. 1684, 1687, 109 L.Ed.2d 85 (1990); Welsh v. Wisconsin, 466 U.S. 740, 104 S.Ct. 2091, 80 L.Ed.2d 732 (1984). The Fourth Amendment protects a person’s reasonable expectation of privacy in a variety of settings, but the chief evil against which the amendment is directed is the physical entry of the home. See Payton, 445 U.S. at 585, 589, 100 S.Ct. at 1379, 1381. “In [no setting] is the zone of privacy more clearly defined than when bounded by the unambiguous physical dimensions of an individual’s home.... ” Id. at 589, 100 S.Ct. at 1381. Thus, the Court held in Payton, the Fourth Amendment draws “a firm line at the entrance to the house. Absent exigent circumstances, that threshold may not reasonably be crossed without a warrant.” Id. at 590, 100 S.Ct. at 1382.
A few years before deciding Payton, however, the Supreme Court had held in United States v. Santana, 427 U.S. 38, 96 S.Ct. 2406, 49 L.Ed.2d 300 (1976), that po*1386lice could arrest without a warrant a person standing in the open doorway to her home because the open doorway was a public place. In Santana, police saw “Mom” Santana standing in the open doorway to her home shortly after a heroin transaction they had probable cause to believe she participated in. The police pulled their van up near her home, exited the van, identified themselves, and approached Santana to arrest her. Santana fled into her home; the police followed and arrested her. Id. at 40-41, 96 S.Ct. at 2408-09.
The Supreme Court upheld Santana’s arrest. First, the Court held Santana had no reasonable expectation of privacy standing in her open doorway: “She was not merely visible to the public but was as exposed to public view, speech, hearing, and touch as if she had been standing completely outside her house.” Id. at 42, 96 S.Ct. at 2409. Thus, the police could arrest Santana in her doorway under the Court’s decision in United States v. Watson, 423 U.S. 411, 96 S.Ct. 820, 46 L.Ed.2d 598 (1976), that police with probable cause to arrest may arrest a person in a public place without a warrant.
The police, however, were not actually able to complete Santana’s arrest in her doorway; they had to enter her home to bring her under their control. The Court upheld the arrest in the home, not because the home was a public place, but because Santana could not thwart an arrest begun in a public place (her open doorway) by retreating into her house. Id. 427 U.S. at 42-43, 96 S.Ct. at 2409-10. The entry into Santana’s home was justified by an exigent circumstance: the police’s “hot pursuit” of a fleeing felon. See id.
If Berkowitz’s arrest occurred as the government says it did, the arrest was legal. Courts have generally upheld arrests such as that described by Shearer in this case, where the police go to a person’s home without a warrant, knock on the door, announce from outside the home the person is under arrest when he opens the door to answer, and the person acquiesces to the arrest. See, e.g., McKinney v. George, 726 F.2d 1183, 1188 (7th Cir.1984); United States v. Carrion, 809 F.2d 1120, 1128 (5th Cir.1987); United States v. Whitten, 706 F.2d 1000, 1015 (9th Cir.1983); United States v. Botero, 589 F.2d 430 (9th Cir.1978); see generally 2 Wayne R. La Fave, Search and Seizure § 6.1(e), at 589-61 (2d ed. 1987). While most of these cases have justified their holdings as applications of Santana, the arrests in these cases, and the arrest here as Shearer presents it, are consistent with Payton. It is true that Berkowitz was still standing inside his home when Shearer told him he was under arrest. But Payton prohibits only a war-rantless entry into the home, not a policeman’s use of his voice to convey a message of arrest from outside the home. See La Fave, supra, § 6.1(e) at 590. Moreover, there is nothing in Payton that prohibits a person from surrendering to police at his doorway. Id. The agents in this case (even as Shearer tells it) did enter Berkow-itz’s house (remaining immediately adjacent to his doorway) after Shearer told Berkow-itz he was under arrest. But from Shearer’s affidavit, it appears Berkowitz submitted to the agents’ authority to arrest him before they entered. For reasons we will explain shortly, we do not think the agents’ entry (if the facts are as Shearer states) violated any reasonable privacy expectation of Berkowitz’s, and therefore did not violate Payton.
As Berkowitz presents the arrest, however, Shearer and the other IRS agents entered his home before announcing he was under arrest. One might argue that this should not make a difference; Berkowitz was standing at or near his doorway, and Santana says the doorway is a public place. Moreover, one might argue that a search’s legality should not turn on such subtle distinctions as whether the police announce an arrest before entering a home, or wait until after entry to announce the arrest (so long as the police stay near the doorway). We find these arguments unpersuasive for several reasons.
Payton holds the Fourth Amendment draws a clear line at the entrance of a person’s house: “Absent exigent circumstances, that threshold may not reasonably be crossed without a warrant.” 445 U.S. at 590, 100 S.Ct. at 1382. Entering a person’s *1387home without a warrant to arrest him, where no exigent circumstances exist, violates this clear command. The government has not cited any “knock and arrest” cases upholding arrests where the police entered the arrestee’s home before telling the person he was under arrest. The Fourth Circuit has recently held that a warrantless nonconsenual entry into a hotel room to arrest a subject who answered a knock at his door and was standing near the door when the police entered violates Payton. United States v. McCraw, 920 F.2d 224, 228-30 (4th Cir.1990). A case from this circuit also indicates that such an arrest would be illegal. In United States v. Diaz, 814 F.2d 454 (7th Cir.1987), an undercover officer was in Diaz’s hotel room testing cocaine he was supposed to buy from Diaz. The officer told Diaz the cocaine was acceptable, and left the room purportedly to call his “money man.” After leaving the room, the officer gave a signal to other officers stationed near the room. The first officer then went back to the room, and knocked on the door. When Diaz answered, the other officers entered the room and arrested him. See id. at 456. This court upheld the search on the basis of Diaz’s original consent to the first officer to be in the hotel room. But although Diaz was at the doorway to his hotel room when the other officers entered and arrested, we held there were no exigent circumstances to justify the entry, thus indicating that absent Diaz’s consent to the first officer the warrantless entry to arrest Diaz would have violated the Fourth Amendment as interpreted in Payton. See id. at 458-59.
That warrantless entry before arrest is not legal (and, conversely, that a slight entry after the defendant has submitted to the police is legal) can be seen from analyzing the privacy interests involved in the situation. The Fourth Amendment protects people’s legitimate expectations of privacy. A person’s subjective privacy expectation in any situation is legitimate, and therefore worthy of Fourth Amendment protection, if it is “one that society is prepared to recognize as reasonable.” Minnesota v. Olson, 110 S.Ct. at 1687 (citation omitted).
As the Court noted in Payton, there is no place where a person’s expectation of privacy is greater than in his own home. See Payton, 445 U.S. at 589, 100 S.Ct. at 1381. A person does not abandon this privacy interest in his home by opening his door from within to answer a knock. Answering a knock at the door is not an invitation to come in the house. We think society would recognize a person’s right to choose to close his door on and exclude people he does not want within his home. This right to exclude is one of the most — if not the most — important components of a person’s privacy expectation in his home.
When the police assert from outside the home their authority to arrest a person, they have not breached the person's privacy interest in the home. If the person recognizes and submits to that authority, the arrestee, in effect, has forfeited the privacy of his home to a certain extent. At that point, it is not unreasonable for the police to enter the home to the extent necessary to complete the arrest. A person who has submitted to the police’s authority and stands waiting for the police to take him away can hardly complain when the police enter his home briefly to complete the arrest. This is why, if Shearer’s version of the arrest is true, it would not have violated the Fourth Amendment for Shearer and the other agents to enter Berkow-itz’s house after announcing the arrest, and remain near his door, to take Berkowitz under their control.
It is a different matter, however, for the police to enter a person’s home, without his consent, before announcing their authority to arrest. In that case, the arrestee has not forfeited his privacy interest in the home; he has not relinquished his right to close the door on the unwanted visitors. See McCraw, 920 F.2d at 229; see also McKinney v. George, 726 F.2d at 1188 (suggesting that a person answering the police’s knock may retreat into his home, and that police may not then enter without a warrant to arrest him); La Fave, supra, § 6.1(e) at 591. Indeed, the police have not even given him a chance to exercise that right. Payton holds that police may not *1388enter a person’s home without a warrant to arrest him; to hold it was proper for Shearer and his cohorts to enter Berkowitz’s home in this case before announcing his arrest would be to sanction the very conduct that Payton holds the Fourth Amendment forbids.
Santana does not require a different result. As far as reasonable privacy expectations go, there is a significant difference between a person who for no reason voluntarily decides to stand in his open doorway, and a person who merely answers a knock on his door. The person who answers the knock and stays within the house is not voluntarily exposing himself "to public view, speech, hearing, and touch as if [he is] standing completely outside [his] house.” Santana, 427 U.S. at 42, 96 S.Ct. at 2409. Moreover, the entry in Santana was justified by hot pursuit; Santana had just completed a heroin transaction, she voluntarily relinquished her privacy expectation in her home by exposing herself to the public in her open doorway, the police began the arrest while Santana had no reasonable privacy expectation, and there was a real possibility that delaying her arrest would result in her destroying evidence. See id. at 42-43, 96 S.Ct. at 2409-10. In this case, there was no justification for Shearer and the other agents to enter Berkowitz’s home to arrest him without a warrant.
One might argue that to disallow the minimal entry into the home to arrest in this case could hamstring police. But Pay-ton forbids any non-consensual warrantless entry into the home absent exigent circumstances. Payton did not draw the line one or two feet into the home; it drew the line at the home’s entrance. Also, if police go to a person’s home to arrest him, and have reason to believe they may have to enter the home to make the arrest, they should obtain a warrant. There was no reason in this case for Shearer and his cohorts not to get a warrant, and plenty of reason to obtain a warrant. What would have happened if Berkowitz had refused to open his door to the police? Or if another member of Berkowitz’s family had answered the door, but Berkowitz refused to come to the door? The agents would have had to go back and get a warrant (after having effectively warned Berkowitz that they suspected him of stealing documents, something that would have created a real danger that Berkowitz would destroy evidence or try to flee). Obtaining a warrant in the first place would have prevented these potential problems, to say nothing of the time it would have saved at trial and on appeal litigating the legality of Berkowitz’s arrest.
Because there is a factual dispute in this case, and because resolving that dispute is necessary to determine whether Berkow-itz’s arrest was legal, the district judge should have held an evidentiary hearing. Therefore, we must reverse and remand so that the judge may hold that hearing.

B. Plain View Seizure of Documents.

There are two other questions we must answer concerning Berkowitz’s motion to suppress, assuming that if on remand the court determines Berkowitz’s arrest was legal. Both center around whether Shearer legally seized documents from Berkowitz’s home office at the time of his arrest. Since Shearer did not have a warrant to seize those documents, the seizure was proper only under the plain view exception to the warrant requirement. A warrantless seizure is justified under the plain view doctrine if the officer has a legal right to be in the place from where he sees the object subject to seizure and “a lawful right of access to the object itself,” and if “ ‘the object’s incriminating nature is immediately apparent.’ ” Horton v. California, — U.S. -, 110 S.Ct. 2301, 2308, 110 L.Ed.2d 112 (1990). The two questions we must answer (assuming the arrest to be legal) are whether Shearer had a right to be in Berkowitz’s office when he discovered the documents, and whether it was “immediately apparent” to Shearer that those were government documents. (There is no dispute, assuming Shearer’s presence in the office was legal, about whether Shearer had a lawful right of access to the documents he seized, since they were lying in the open in a place he had a right to be.)
*1389There is no material factual dispute about Shearer’s presence in Berkowitz’s office. Both parties agree that Berkowitz told the agents that he wanted to get his keys, and that Shearer followed Berkowitz into his office where his keys were. While the government asserts that Berkowitz consented to being followed and Berkowitz asserts he did not consent, this factual dispute is unimportant. In Washington v. Chrisman, 455 U.S. 1, 102 S.Ct. 812, 70 L.Ed.2d 778 (1982), the Supreme Court held that when police lawfully arrest a person, they may follow that person into his home to monitor him, and seize any contraband they find in plain view. That is exactly what occurred here. The officer’s authority to monitor a suspect does not depend on the suspect’s consent; a suspect under arrest has no right to wander off on his own. Thus, the district court correctly held that Shearer could legally follow Berkowitz into his office.
The second requirement, that an object’s incriminating nature be “immediately apparent,” is met where a police officer, upon seeing the object, has probable cause to believe the object is contraband or evidence of a crime. Arizona v. Hicks, 480 U.S. 321, 327, 107 S.Ct. 1149, 1153, 94 L.Ed.2d 347 (1987). In this case, Shearer stated in his affidavit he observed “numerous files” on top of the desk in Berkowitz’s office and under the desk’s alcove area. Shearer stated that he “immediately recognized” the files as those that had been stored in the USA’s office. He knew the files were from the USA’s office because, among other things, he recognized his own handwriting on some of the files. Shearer also stated that he saw some original income tax returns.
Shearer’s affidavit is sufficient to show that it was “immediately apparent” to him the files he saw in and seized from Berkow-itz’s office were taken from the USA’s office. Berkowitz, however, disputes several of the facts in Shearer’s affidavit. The question, therefore, is whether these disputed facts are material, so that the district court should have taken evidence concerning the seizure.
None of the factual disputes concerning the documents’ seizure is material. Ber-kowitz states that it would not have been immediately apparent from looking at any files on his desk that they were government files. However, Berkowitz cannot contest what would have been apparent to Shearer (who was the agent responsible for investigating the tax fraud case) just by baldly asserting what he thinks would have been apparent.
Berkowitz also stated that there were no papers in the alcove area under his desk. But Shearer stated he saw files in the alcove area, not papers. In any event, even if Shearer was mistaken about seeing files in the alcove area, the fact remains that Shearer did seize files from Berkow-itz’s office that were in plain view. Any dispute about precisely where Shearer actually found the files is not relevant to the question of whether it was immediately apparent to Shearer that the files he did find were government files.
Finally, Berkowitz stated that there were no original tax returns on top of his desk. However, Berkowitz does not contest that Shearer actually seized original tax returns. Even if those tax returns were in the files, they were seizable because the files themselves were seizable. Berkowitz does not dispute that Shearer’s handwriting was on the files, or that there were other reasons for him to recognize the files. Thus, the fact that there may have been no original tax returns on top of the desk is not material to whether Shearer legally seized the documents he found in plain view in Berkowitz’s office. Since there is no material factual dispute concerning Shearer’s seizure of documents at the time of the arrest, if Berkowitz’s arrest was legal, the seizure of the documents was legal.1
*1390IV. Sentencing

A. Offense Level Increase for Destroying Documents.

Since Berkowitz’s conviction may still stand after the district court holds an evidentiary hearing concerning his arrest, we consider Berkowitz’s challenges to his sentence. Berkowitz first argues that the district court erred by increasing his offense level for the obstruction of justice counts eight levels because he destroyed documents. Sentencing Guideline § 2J1.2(b)(l) provides for an eight-level increase for obstruction of justice offenses “[i]f the defendant obstructed or attempted to obstruct justice by causing or threatening to cause physical injury to a person or property....” Berkowitz argues that § 2J1.2(b)(l)’s eight-level increase applies only when property damage is used to intimidate a witness or inflict emotional distress. That is not, however, what the guideline says, and there is nothing in the commentary to § 2J1.2 to support Berkow-itz's argument. Section 2J1.2(b)(l) provides for an eight-level increase where the offense involves property damage; since Berkowitz destroyed government documents, that increase applies here.

B. Amount of Loss.

Berkowitz next argues that the district court erred by increasing the offense level for his theft conviction by eight levels. Guideline § 2B1.1 provides a base offense level of four for theft, and then increases the offense level as the amount of loss from the theft rises. For losses between $100,001 and $200,000, § 2Bl.l(b)(l)(I) provides for an eight-level increase. Berkowitz argues that the government did not introduce sufficient evidence to support the district judge’s finding that the government’s loss from his theft amounted to more than $100,000.
Section 2B1.1, Application Note 2, provides that “loss” ordinarily means the market value of the property stolen. However, “[wjhere the market value is difficult to ascertain or inadequate to measure harm to the victim, the court may measure loss in some other way, such as reasonable replacement cost to the victim.” Id. The government estimated that the replacement cost of the documents Berkowitz stole would be more than $100,000. The government based its estimate on the effort it would take to duplicate the missing documents, including the time at least a dozen banks would have to spend duplicating documents, and the time the government would have to spend reorganizing the documents, reinterviewing witnesses, obtaining new copies of documents the witnesses had previously supplied, and recopying stolen undercover tape recordings. Time is money, and the value of the labor involved in replacing the stolen documents is part of the cost of replacing them. Moreover, time a person spends doing one thing is time that person cannot spend doing something else; therefore, opportunity costs must also be factored into the cost of replacing the documents. “[LJoss need not be determined with precision, and may be inferred from any reasonably reliable information available_” Guideline § 2B1.1, Application Note 3. Given that Berkowitz produced no evidence to challenge the government’s assertions about replacing the documents, those assertions were sufficient to support the trial judge’s finding that the loss exceeded $100,000.
Berkowitz also argues that the district court in determining the amount of loss should have considered the government’s failure to mitigate. This argument is mer-itless. Berkowitz’s crime is the same whether or not the government mitigated its loss, and the government’s lack of mitigation is irrelevant to Berkowitz’s culpability. Besides, Application Note 2 indicates that mitigation is not required. For example, the note provides that if a defendant steals a car, the loss refers to the value of the car even if the vehicle is recovered immediately. In that case, the victim’s true loss is the value of not having his car *1391for a certain amount of time, and any other losses flowing from not having the car. In the case where the car is returned immediately, that loss is likely to be very small. Yet, loss is still measured by the car’s market value. Similarly, even though the government might have been able to mitigate its loss, the loss should still be measured by the value of the documents stolen — in this case, the documents’ replacement cost.

C. Upward, Departure.

Berkowitz next argues that the district court erred by departing upward from criminal history category I (the category based on Berkowitz’s prior criminal record) to category III. Guideline § 4A1.3 provides that “if the criminal history category does not adequately reflect the seriousness of the defendant’s past criminal conduct or the likelihood that the defendant will commit other crimes” the court may depart upward. As an example of the kind of information the judge may consider in deciding to depart upward, § 4A1.3(d) provides that the judge may consider “whether the defendant was pending trial ... on another charge at the time of the instant offense.” Section 4A1.3 then gives as an example of when a departure is warranted “the case of a defendant who ... committed the instant offense while on bail or pretrial release for another serious offense.”
The district judge quite logically applied the straightforward language in § 4A1.3 and departed upward because “Berkowitz committed the instant offenses while serious tax fraud and mail fraud charges were pending against him, and after he had been released on bond.” But despite § 4A1.3’s straightforward language, Berkowitz argues that the departure was unwarranted because the tax fraud case and this case were so closely related that the fact he stole the documents while out on bond for the tax fraud case indicates nothing about his likelihood of committing future crimes. We disagree. Most criminal defendants do not try to impede their prosecutions by stealing and destroying government evidence. Perhaps they realize stealing and destroying evidence would be wrong. More likely they realize that attempts to impede the prosecution will only land them in bigger trouble than they are already in. But neither the fact that such action was wrong nor the fact that his attempt to impede the prosecution could have serious adverse consequences deterred Berkowitz from stealing and destroying government documents. Given this, it is reasonable to conclude that Berkowitz might be more likely than the average offender to resort to crime in the future if he thought it to be to his advantage.
Berkowitz attempts to make two other arguments concerning the upward departure. First, he states that since 18 U.S.C. § 3147 and Guideline § 2J1.7 “cover” the commission of offenses while on bond, the court may not properly depart under § 4A1.3. Second, he states that the district judge did not follow a proper procedure in deciding to depart to criminal history category III. Since his argument concerning 18 U.S.C. § 3147 and Guideline § 2J1.7 is a perfunctory two-sentence argument that does not explain how those provisions “cover” this situation, and that cites no applicable authority, he has waived it. See United States v. Petitjean, 883 F.2d at 1349. He has also waived his procedural argument because he raised it for the first time in his reply brief. See Fed.R.App.P. 28; Seventh Circuit Rule 28(f); Reynolds v. East Dyer Development Co., 882 F.2d 1249, 1253 n. 2 (7th Cir.1989).

D. Failure to Depart Downward.

Berkowitz finally argues that the district court should have departed downward from the otherwise applicable guideline range because of a psychiatrist’s testimony about Berkowitz’s mental state at the time of his offense. However, we have no jurisdiction to review a district court’s decision not to depart, United States v. Franz, 886 F.2d 973 (7th Cir.1989), and thus may not consider this argument.
V.
To sum up: We reject Berkowitz’s claims that he received ineffective assistance of *1392counsel at trial and that the trial judge deprived him of assistance of counsel. We also hold that Berkowitz’s sentence was proper. However, we reverse and remand this case to the district court to hold an evidentiary hearing concerning Berkowitz’s arrest. Circuit Rule 36 shall not apply on remand.

. If Berkowitz’s arrest was not legal, it follows that Shearer had no right to follow Berkowitz into his office, and we could not uphold the seizure of the documents on the basis that Chris-man allowed Shearer to be in the office where he saw the documents in plain view. However, nothing in this opinion prevents the government from arguing any other theory to uphold the *1390seizure (e.g., inevitable discovery) if the district court finds Berkowitz’s arrest illegal. We express no view about whether any other theory the government might argue would be successful.
