|NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
|(Unaudited)                               





Note A  Basis of Presentation



As of December 31, 2006, Century Properties Fund XVIII (the Partnership or Registrant) adopted the liquidation basis of accounting due to the sale of its remaining investment property (as discussed in Note B  Disposition of Investment Property). Fox Partners (the General Partner), a California general partnership, is the general partner of the Registrant. The general partners of Fox Partners are Fox Capital Management Corporation (the "Managing General Partner" or "FCMC"), a California corporation, Fox Realty Investors ("FRI"), a California general partnership, and Fox Partners 82, a California general partnership. NPI Equity Investments II, Inc. ("NPI Equity"), a Florida corporation, is the managing general partner of FRI. The Managing General Partner, as well as the managing general partner of FRI, are affiliates of Apartment Investment and Management Company ("AIMCO"), a publicly traded real estate investment trust.



As a result of the decision to liquidate the Partnership, the Partnership changed its basis of accounting for its consolidated financial statements at December 31, 2006, to the liquidation basis of accounting.  Consequently, assets have been valued at estimated net realizable value and liabilities are presented at their estimated settlement amounts, including estimated costs associated with carrying out the liquidation of the Partnership. The valuation of assets and liabilities necessarily requires many estimates and assumptions and there are substantial uncertainties in carrying out the liquidation. The actual realization of assets and settlement of liabilities could be higher or lower than amounts indicated and is based upon the Managing General Partners estimates as of the date of the consolidated financial statements.



As of December 31, 2006 the General Partner had a deficit balance in its capital account of $5,090,000.  Paragraph 5.3 of the Partnership Agreement states, In the event that, immediately prior to the dissolution and termination of the Partnership following the sale or exchange of all of the Properties, and after crediting any gain or charging any loss pursuant to Paragraph 11.2, the General Partner shall have a deficiency in its capital account as determined in accordance with the accrual method of accounting, then the General Partner shall contribute in cash to the capital account of the Partnership an amount which is equal to the deficiency in its capital account.



The Partnership is evaluating the language of Paragraph 5.3 as it relates to the Partnership Agreement in its entirety, whether the General Partner will be required to contribute funds, how much the General Partner would be required to contribute if there is an obligation and whether the General Partner and its partners have sufficient funds available to meet any contribution requirements.  The General Partner has disputed whether Paragraph 5.3 requires a contribution, has questioned the amount of the deficit balance and has asserted that sufficient funds may not be available should a contribution be required.  As a result, the Partnership has not recorded a receivable for the deficit balance of $5,090,000 in the General Partner's capital account as of December 31, 2006.



The Managing General Partner estimates that the liquidation process will be completed by December 31, 2007.  Because the success in realization of assets and the settlement of liabilities is based on the Managing General Partners best estimates, the liquidation period may be shorter than projected or it may be extended beyond the projected period.



The accompanying unaudited consolidated financial statements of the Partnership have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-QSB and Item 310(b) of Regulation S-B.  Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  In the opinion of the Managing General Partner, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  For further information, refer to the consolidated financial statements and footnotes included in the Partnerships Annual Report on Form 10-KSB for the fiscal year ended December 31, 2006.



Note B  Disposition of Investment Property



On December 28, 2006, the Partnership sold its sole investment property, Oak Run Apartments, to a third party. In addition to Oak Run Apartments, the third party also purchased three other apartment complexes, each of which was owned in whole or in part by affiliates of AIMCO, an affiliate of the Managing General Partner.  The total sales price for Oak Run Apartments and the other three properties was approximately $48,700,000, of which approximately $13,250,000 was allocated to Oak Run Apartments. The net proceeds realized by the Partnership were approximately $13,015,000 after payment of closing costs.  The Partnership used approximately $8,500,000 to repay the mortgage encumbering the property and approximately $85,000 for a prepayment penalty.  The Partnership realized a gain of approximately $2,742,000 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $134,000 as a result of the write-off of unamortized loan costs of approximately $49,000 and a prepayment penalty of approximately $85,000.



Note C  Transactions with Affiliated Parties



The Partnership has no employees and depends on the Managing General Partner and its affiliates for the management and administration of all Partnership activities. The Partnership Agreement provides for payments to affiliates for services and reimbursement of certain expenses incurred by affiliates on behalf of the Partnership.



Affiliates of the Managing General Partner received 5% of gross receipts from the Partnership's property as compensation for providing property management services. The Partnership paid to such affiliates approximately $31,000 for the three months ended March 31, 2006, which was included in operating expenses.



As compensation for the services rendered in managing the Partnership, the Managing General Partner was entitled to receive a Partnership Management Fee equal to 9% of distributions from operations as defined in the Partnership Agreement. During the three months ended March 31, 2007 and 2006, no amounts were paid to the Managing General Partner as there were no distributions.



An affiliate of the Managing General Partner charged the Partnership reimbursement of accountable administrative expenses amounting to approximately $27,000 and $26,000 for the three months ended March 31, 2007 and 2006, respectively, which are included in general and administrative expenses.



An affiliate of the Managing General Partner had made available to the Partnership a credit line of up to $150,000 per property owned by the Partnership.  The affiliate of the Managing General Partner agreed to advance funds to the Partnership in excess of the $150,000 credit line in prior years. During the three months ended March 31, 2006, approximately $128,000 was advanced to Oak Run Apartments for operating expenses. Interest accrued at the prime rate plus 2%. There were no advances received during the three months ended March 31, 2007. Interest expense amounted to approximately $20,000 and $71,000 for the three months ended March 31, 2007 and 2006, respectively. During the three months ended March 31, 2007, the Partnership repaid approximately $3,817,000 of advances and accrued interest from the proceeds received from the sale of the Partnerships remaining investment property. No amounts were owed at March 31, 2007.





The Partnership insured its property up to certain limits through coverage provided by AIMCO which is generally self-insured for a portion of losses and liabilities related to workers compensation, property casualty, general liability and vehicle liability.  The Partnership insured its property above the AIMCO limits through insurance policies obtained by AIMCO from insurers unaffiliated with the Managing General Partner. The Partnership was charged by AIMCO and its affiliates approximately $68,000 for insurance coverage and fees associated with policy claims administration during the year ended December 31, 2006.



Note D  Casualty Gain



During the year ended December 31, 2005, a net casualty gain of approximately $8,000 was recorded at Oak Run Apartments. The casualty gain related to a fire, which occurred in May 2005, causing damage to one unit at the property. The gain was the result of the receipt of insurance proceeds of approximately $13,000 offset by approximately $5,000 of undepreciated property improvements and replacements being written off.  During the three months ended March 31, 2006 additional insurance proceeds of approximately $34,000 were received.  Approximately $10,000 of which resulted in additional gain being recognized in the first quarter of 2006 and approximately $24,000 of which was received to cover emergency expenses which were included in operating expenses during 2005. This amount is included in operating expenses for the three months ended March 31, 2006.



Note E  Contingencies



In March 1998, several putative unit holders of limited partnership units of the Partnership commenced an action entitled Rosalie Nuanes, et al. v. Insignia Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the State of California for the County of San Mateo. The plaintiffs named as defendants, among others, the Partnership, its Managing General Partner and several of their affiliated partnerships and corporate entities. The action purported to assert claims on behalf of a class of limited partners and derivatively on behalf of a number of limited partnerships (including the Partnership) that are named as nominal defendants, challenging, among other things, the acquisition of interests in certain Managing General Partner entities by Insignia Financial Group, Inc. ("Insignia") and entities that were, at one time, affiliates of Insignia; past tender offers by the Insignia affiliates to acquire limited partnership units; management of the partnerships by the Insignia affiliates; and the series of transactions which closed on October 1, 1998 and February 26, 1999 whereby Insignia and Insignia Properties Trust, respectively, were merged into AIMCO. The plaintiffs sought monetary damages and equitable relief, including judicial dissolution of the Partnership. In addition, during the third quarter of 2001, a complaint captioned Heller v. Insignia Financial Group (the "Heller action") was filed against the same defendants that are named in the Nuanes action. On or about August 6, 2001, plaintiffs filed a first amended complaint. The Heller action was brought as a purported derivative action, and asserted claims for, among other things, breach of fiduciary duty, unfair competition, conversion, unjust enrichment, and judicial dissolution. On January 28, 2002, the trial court granted defendants motion to strike the complaint.  Plaintiffs took an appeal from this order.



On January 8, 2003, the parties filed a Stipulation of Settlement in proposed settlement of the Nuanes action and the Heller action. On June 13, 2003, the court granted final approval of the settlement and entered judgment in both the Nuanes and Heller actions. On August 12, 2003, an objector ("Objector") filed an appeal (the Appeal) seeking to vacate and/or reverse the order approving the settlement and entering judgment thereto. On May 4, 2004, the Objector filed a second appeal challenging the courts use of a referee and its order requiring Objector to pay those fees.



On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.  With regard to the settlement and judgment entered thereto, the Court of Appeals vacated the trial courts order and remanded to the trial court for further findings on the basis that the state of the record is insufficient to permit meaningful appellate review.  The matter was transferred back to the trial court on June 21, 2005.  With regard to the second appeal, the Court of Appeals reversed the order requiring the Objector to pay referee fees. With respect to the related Heller appeal, on July 28, 2005, the Court of Appeals reversed the trial courts order striking the first amended complaint.



On August 18, 2005, Objector and his counsel filed a motion to disqualify the trial court based on a peremptory challenge and filed a motion to disqualify for cause on October 17, 2005, both of which were ultimately denied and/or struck by the trial court.  On or about October 13, 2005 Objector filed a motion to intervene and on or about October 19, 2005 filed both a motion to take discovery relating to the adequacy of plaintiffs as derivative representatives and a motion to dissolve the anti-suit injunction in connection with settlement.  On November 14, 2005, Plaintiffs filed a Motion For Further Findings pursuant to the remand ordered by the Court of Appeals. Defendants joined in that motion.  On February 3, 2006, the Court held a hearing on the various matters pending before it and ordered additional briefing from the parties and Objector. On June 30, 2006, the trial court entered an order confirming its approval of the class action settlement and entering judgment thereto after the Court of Appeals had remanded the matter for further findings. The substantive terms of the settlement agreement remain unchanged.  The trial court also entered supplemental orders on July 1, 2006, denying Objectors Motion to File a Complaint in Intervention, Objectors Motion for Leave of Discovery and Objectors Motion to Dissolve the Anti-Suit Injunction.  Notice of Entry of Judgment was served on July 10, 2006.  On August 31, 2006, the Objector filed a Notice of Appeal to the Courts June 30, 2006 and July 1, 2006 orders. On December 14, 2006, Objector filed his Appellants Brief. The Partnership and its affiliates, as well as counsel of the Settlement Class, have not yet filed their briefs in response.



The Managing General Partner does not anticipate that any costs to the Partnership, whether legal or settlement costs, associated with these cases will be material to the Partnerships overall operations.



AIMCO Properties, L.P. and NHP Management Company, both affiliates of the Managing General Partner, are defendants in a lawsuit alleging that they willfully violated the Fair Labor Standards Act (FLSA) by failing to pay maintenance workers overtime for all hours worked in excess of forty per week. The complaint, filed in the United States District Court for the District of Columbia, attempts to bring a collective action under the FLSA and seeks to certify state subclasses in California, Maryland, and the District of Columbia. Specifically, the plaintiffs contend that AIMCO Properties, L.P. and NHP Management Company failed to compensate maintenance workers for time that they were required to be "on-call." Additionally, the complaint alleges AIMCO Properties, L.P. and NHP Management Company failed to comply with the FLSA in compensating maintenance workers for time that they worked in excess of 40 hours in a week.   In June 2005 the court conditionally certified the collective action on both the on-call and overtime issues.  Approximately 1,049 individuals opted in to the class. On March 28, 2007, the court issued an opinion decertifying the collective action on both issues.  The court held that the members of the collective action are not similarly situated and the case may not proceed as a collective action.  The nine named plaintiffs still maintain their individual causes of action. The California and Maryland cases are still pending as they were stayed pending the outcome of the decertification motion in the District of Columbia case.  Although the outcome of any litigation is uncertain, AIMCO Properties, L.P. does not believe that the ultimate outcome will have a material adverse effect on its consolidated financial condition or results of operations. Similarly, the Managing General Partner does not believe that the ultimate outcome will have a material adverse effect on the Partnerships consolidated financial condition or results of operations.





The Partnership is unaware of any other pending or outstanding litigation matters involving it that are not of a routine nature arising in the ordinary course of business.













ITEM 2.

MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION



The matters discussed in this report contain certain forward-looking statements, including, without limitation, statements regarding future financial performance and the effect of government regulations. Actual results may differ materially from those described in the forward-looking statements and will be affected by a variety of risks and factors including, without limitation: national and local economic conditions; the terms of governmental regulations that affect the Registrant and interpretations of those regulations; litigation, including costs associated with prosecuting and defending claims and any adverse outcomes, and possible environmental liabilities. Readers should carefully review the Registrant's financial statements and the notes thereto, as well as the risk factors described in the documents the Registrant files from time to time with the Securities and Exchange Commission.



Results from Operations



As of December 31, 2006, the Partnership adopted the liquidation basis of accounting, due to the sale of its remaining investment property.



On December 28, 2006, the Partnership sold its sole investment property, Oak Run Apartments, to a third party. In addition to Oak Run Apartments, the third party also purchased three other apartment complexes, each of which was owned in whole or in part by affiliates of AIMCO, an affiliate of the Managing General Partner.  The total sales price for Oak Run Apartments and the other three properties was approximately $48,700,000, of which approximately $13,250,000 was allocated to Oak Run Apartments. The net proceeds realized by the Partnership were approximately $13,015,000 after payment of closing costs.  The Partnership used approximately $8,500,000 to repay the mortgage encumbering the property and approximately $85,000 for a prepayment penalty.  The Partnership realized a gain of approximately $2,742,000 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $134,000 as a result of the write-off of unamortized loan costs of approximately $49,000 and a prepayment penalty of approximately $85,000.



As a result of the decision to liquidate the Partnership, the Partnership changed its basis of accounting for its consolidated financial statements at December 31, 2006, to the liquidation basis of accounting.  Consequently, assets have been valued at estimated net realizable value and liabilities are presented at their estimated settlement amounts, including estimated costs associated with carrying out the liquidation of the Partnership. The valuation of assets and liabilities necessarily requires many estimates and assumptions and there are substantial uncertainties in carrying out the liquidation. The actual realization of assets and settlement of liabilities could be higher or lower than amounts indicated and is based upon estimates of the Managing General Partner as of the date of the consolidated financial statements.



During the three months ended March 31, 2007, net assets in liquidation decreased by approximately $47,000. The decrease in net assets in liquidation is primarily due to decreases in cash and cash equivalents, receivables and deposits, accounts payable, other liabilities, due to affiliates and the estimated costs during the period of liquidation. The decrease in cash and cash equivalents and due to affiliates is due to the Partnerships payment of advances and related accrued interest from an affiliate of the Managing General Partner. The decrease in receivables and deposits is due to the collection of receivables and escrows relating to the sale of the Partnerships investment property. The decrease in accounts payable is due to the payment of trailing payables relating to the sale of the Partnerships investment property.  The decrease in other liabilities is due to the payment of costs associated with the quarterly and annual communications with investors and regulatory agencies and the annual audit required by the Partnership Agreement.



The consolidated statement of net assets in liquidation as of March 31, 2007 includes approximately $36,000 of costs that the Managing General Partner estimates will be incurred during the period of liquidation, based on the assumption that the liquidation process will be completed by December 31, 2007.  Because the success in realization of assets and the settlement of liabilities, is based on the Managing General Partners best estimates, the liquidation period may be shorter than projected or extended beyond December 31, 2007, the projected date of liquidation.



As of December 31, 2006 the General Partner had a deficit balance in its capital account of $5,090,000.  Paragraph 5.3 of the Partnership Agreement states, In the event that, immediately prior to the dissolution and termination of the Partnership following the sale or exchange of all of the Properties, and after crediting any gain or charging any loss pursuant to Paragraph 11.2, the General Partner shall have a deficiency in its capital account as determined in accordance with the accrual method of accounting, then the General Partner shall contribute in cash to the capital account of the Partnership an amount which is equal to the deficiency in its capital account.



The Partnership is evaluating the language of Paragraph 5.3 as it relates to the Partnership Agreement in its entirety, whether the General Partner will be required to contribute funds, how much the General Partner would be required to contribute if there is an obligation and whether the General Partner and its partners have sufficient funds available to meet any contribution requirements.  The General Partner has disputed whether Paragraph 5.3 requires a contribution, has questioned the amount of the deficit balance and has asserted that sufficient funds may not be available should a contribution be required.  As a result, the Partnership has not recorded a receivable for the deficit balance of $5,090,000 in the General Partner's capital account as of December 31, 2006.



There were no cash distributions during the three months ended March 31, 2007 and 2006.  Future cash distributions, if any, will depend on the amount of cash remaining after fully liquidating the Partnership. The Partnerships cash available for distributions will be reviewed on a quarterly basis. There can be no assurance, however, that the Partnership will have any funds available after liquidation to permit distributions to its partners in 2007.



Other



In addition to its indirect ownership of the general partner interests in the Partnership, AIMCO and its affiliates owned 42,694.50 limited partnership units (the "Units") in the Partnership representing 56.94% of the outstanding Units at March 31, 2007. A number of these Units were acquired pursuant to tender offers made by AIMCO or its affiliates. Pursuant to the Partnership Agreement, unit holders holding a majority of the Units are entitled to take action with respect to a variety of matters, that include, but are not limited to, voting on certain amendments to the Partnership Agreement and voting to remove the General Partner. As a result of its ownership of 56.94% of the outstanding Units, AIMCO and its affiliates are in a position to influence all such voting decisions with respect to the Partnership. However, with respect to the 21,513 Units acquired on January 19, 2006, AIMCO IPLP, L.P. (IPLP), an affiliate of the Managing General Partner and of AIMCO, agreed to vote such Units: (i) against any increase in compensation payable to the General Partner; and (ii) on all other matters submitted by it or its affiliates, in proportion to the votes cast by third party unitholders. Except for the foregoing, no other limitations are imposed on IPLP's, AIMCO's or any other affiliates right to vote each Unit held. Although the General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner owes fiduciary duties to both the General Partner and AIMCO as the sole stockholder of the Managing General Partner.















ITEM 3.

CONTROLS AND PROCEDURES



(a)

Disclosure Controls and Procedures. The Partnerships management, with the participation of the principal executive officer and principal financial officer of the Managing General Partner, who are the equivalent of the Partnerships principal executive officer and principal financial officer, respectively, has evaluated the effectiveness of the Partnerships disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) as of the end of the period covered by this report. Based on such evaluation, the principal executive officer and principal financial officer of the Managing General Partner, who are the equivalent of the Partnerships principal executive officer and principal financial officer, respectively, have concluded that, as of the end of such period, the Partnerships disclosure controls and procedures are effective.



(b)

Internal Control Over Financial Reporting. There have not been any changes in the Partnerships internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Partnerships internal control over financial reporting.

On May 4, 2004, the Objector filed a second appeal challenging the courts use of a referee and its order requiring Objector to pay those fees.



On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.
