In accordance with Statement of Financial Accounting Standards (SFAS) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the accompanying statement of operations for the three months ended March 31, 2006 reflects the operations of Place du Plantier Apartments and Fairway View I Apartments as loss from discontinued operations due to their sale on March 31, 2006 (see Note D).



Recent Accounting Pronouncements



In September 2006, the Financial Accounting Standard Board (FASB) issued SFAS No. 157, Fair Value Measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts. SFAS No. 157 applies whenever other standards require assets or liabilities to be measured at fair value and does not expand the use of fair value in any new circumstances. SFAS No. 157 establishes a hierarchy that prioritizes the information used in developing fair value estimates. The hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, such as the reporting entitys own data. SFAS No. 157 requires fair value measurements to be disclosed by level within the fair value hierarchy. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The Partnershipdoes not anticipate that the adoption of SFAS No. 157 will have a material effect on the Partnerships financial statements.



In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. The Partnership has not yet determined whether it will elect the fair value option for any of its financial instruments.











Note B - 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 as reimbursement of certain expenses incurred by affiliates on behalf of the Partnership.



Affiliates of the Managing General Partner receive 5% of gross receipts from the Partnership's properties as compensation for providing property management services. The Partnership paid to such affiliates approximately $54,000 and $102,000 for the three months ended March 31, 2007 and 2006, respectively, which is included in operating expenses and loss from discontinued operations.



Affiliates of the Managing General Partner charged the Partnership reimbursement of accountable administrative expenses amounting to approximately $56,000 and $69,000 for the three months ended March 31, 2007 and 2006, respectively, which is included in general and administrative expenses, gain on sale of discontinued operations and investment property.  The portion of these reimbursements included in gain on sale of discontinued operations and investment property for the three months ended March 31, 2007 and 2006 are construction management services provided by an affiliate of the Managing General Partner of approximately $27,000 and $18,000, respectively.



For services relating to the administration of the Partnership and operation of the Partnership's property, the Managing General Partner is entitled to receive payment for non-accountable expenses up to a maximum of $150,000 per year, based upon the number of Partnership units sold, subject to certain limitations. No such reimbursements were made during the three months ended March 31, 2007 or 2006.



As compensation for services rendered in managing the Partnership, the Managing General Partner is entitled to receive Partnership management fees in conjunction with distributions of cash from operations, subject to certain limitations. No such Partnership management fees were earned or paid during the three months ended March 31, 2007 or 2006.



NPI Equity, on behalf of the Partnership and certain affiliated partnerships, has established a revolving credit facility (the "Partnership Revolver") to be used to fund deferred maintenance and working capital needs of the Partnership and certain other affiliated partnerships in the National Property Investors Partnership Series. The maximum draw available to the Partnership under the Partnership Revolver is $500,000. Loans under the Partnership Revolver will have a term of 365 days, be unsecured and will bear interest at the prime rate plus 2% per annum (10.25% at March 31, 2007). The maturity date of any such borrowing accelerates in the event of: (i) the removal of NPI Equity as the managing general partner (whether or not for Cause); (ii) the sale or refinancing of a property by the Partnership (whether or not a borrowing under the Partnership Revolver was made with respect to such property); or (iii) the liquidation of the Partnership. During the three months ended March 31, 2006, an affiliate of the Managing General Partner advanced the Partnership approximately $290,000 to pay outstanding accounts payable at Fairway View I and Colony at Kenilworth Apartments and capital improvements at all three properties. There were no such advances during the three months ended March 31, 2007.  Interest expense for the three months ended March 31, 2006 was approximately $59,000.  During 2006, the Partnership repaid approximately $2,651,000 of advances and accrued interest.



Upon the sale of the Partnership properties, NPI Equity will be entitled to an Incentive Compensation Fee equal to a declining percentage of the difference between the total amount distributed to limited partners and the appraised value of their investment at February 1, 1992. The percentage amount to be realized by NPI Equity, if any, will be dependent upon the year in which the property is sold. Payment of the Incentive Compensation Fee is subordinated to the receipt by the limited partners, of: (a) distributions from capital transaction proceeds of an amount equal to their appraised investment in the Partnership at February 1, 1992, and (b) distributions from all sources (capital transactions as well as cash flow) of an amount equal to six percent (6%) per annum cumulative, non-compounded, on their appraised investment in the Partnership at February 1, 1992. During the three months ended March 31, 2006, these preferences were met and the Managing General Partner was entitled to approximately $247,000 related to the sales of Place du Plantier and Fairway View I Apartments which was paid in the second quarter of 2006.



The Partnership insures 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 insures its property above the AIMCO limits through insurance policies obtained by AIMCO from insurers unaffiliated with the Managing General Partner.  During the three months ended March 31, 2007, the Partnership was charged by AIMCO and its affiliates approximately $83,000 for hazard insurance coverage and fees associated with policy claims administration.  Additional charges will be incurred by the Partnership during 2007 as other insurance policies renew later in the year.  The Partnership was charged by AIMCO and its affiliates approximately $135,000 for insurance coverage and fees associated with policy claims administration during the year ended December 31, 2006.



Note C  Casualty Event



During March 2006, the Partnerships investment property, Colony at Kenilworth Apartments, incurred damage as a result of a fire. During the year ended December 31, 2006, the Partnership recognized a casualty gain of approximately $82,000, which was the result of insurance proceeds received of approximately $82,000, as the damaged assets were fully depreciated.  During the three months ended March 31, 2007, the Partnership recognized an additional casualty gain related to this event of approximately $23,000, which is the result of additional insurance proceeds received of approximately $23,000.



Note D  Sale of Discontinued Operations



On March 31, 2006, the Partnership sold Place du Plantier Apartments to a third party, for net proceeds of approximately $9,207,000 after a deduction for immediate capital needs, a prepayment penalty and payment of closing costs.  The Partnership used approximately $5,694,000 of the net proceeds to repay the mortgage encumbering the property.   The Partnership realized a gain of approximately $7,926,000 during the three months ended March 31, 2006 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $1,277,000 as a result of unamortized loan costs written off and payment of a prepayment penalty.  This amount is included in loss from discontinued operations. Also included in loss from discontinued operations for the three months ended March 31, 2006 is approximately $150,000 of income, including revenues of approximately $501,000.



On March 31, 2006, the Partnership sold Fairway View I Apartments to a third party, for net proceeds of approximately $7,157,000 after a deduction for immediate capital needs, a prepayment penalty owed by the Partnership and payment of closing costs.  The Partnership used approximately $4,610,000 of the net proceeds to repay the mortgage encumbering the property. The Partnership realized a gain of approximately $4,514,000 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $1,016,000 as a result of unamortized loan costs written off and payment of a prepayment penalty.  This amount is included in loss from discontinued operations. Also included in loss from discontinued operations for the three months ended March 31, 2006 is approximately $72,000 of income, including revenues of approximately $435,000.



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 ManagingGeneral 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 financial condition or results of operations.



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



Environmental



Various Federal, state and local laws subject property owners or operators to liability for management, and the costs of removal or remediation, of certain hazardous substances present on a property. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of the hazardous substances. The presence of, or the failure to manage or remedy properly, hazardous substances may adversely affect occupancy at affected apartment communities and the ability to sell or finance affected properties. In addition to the costs associated with investigation and remediation actions brought by government agencies, and potential fines, or penalties imposed by such agencies in connection therewith, the presence of hazardous substances on a property could result in claims by private plaintiffs for personal injury, disease, disability or other infirmities. Various laws also impose liability for the cost of removal, remediation or disposal of hazardous substances through a licensed disposal or treatment facility. Anyone who arranges for the disposal or treatment of hazardous substances is potentially liable under such laws. These laws often impose liability whether or not the person arranging for the disposal ever owned or operated the disposal facility. In connection with the ownership, operation, and management of its investment property, the Partnership could potentially be liable for environmental liabilities or costs associated with its property.



Mold



The Partnership is aware of lawsuits against owners and managers of multifamily properties asserting claims of personal injury and property damage caused by the presence of mold, some of which have resulted in substantial monetary judgments or settlements.  The Partnership has only limited insurance coverage for property damage loss claims arising from the presence of mold and for personal injury claims related to mold exposure.  Affiliates of the Managing General Partner have implemented policies, procedures, third-party audits and training and the Managing General Partner believes that these measures will prevent or eliminate mold exposure and will minimize the effects that mold may have on residents.  To date, the Partnership has not incurred any material costs or liabilities relating to claims of mold exposure or to abate mold conditions.  Because the law regarding mold is unsettled and subject to change the Managing General Partner can make no assurance that liabilities resulting from the presence of or exposure to mold will not have a material adverse effect on the Partnerships financial condition or results of operations.











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; the competitive environment in which the Registrant operates; financing risks, including the risk that cash flows from operations may be insufficient to meet required payments of principal and interest; real estate risks, including variations of real estate values and the general economic climate in local markets and competition for tenants in such markets; 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.



The Partnership's investment property consists of one apartment complex. The following table sets forth the average occupancy of the property for the three months ended March 31, 2007 and 2006:



|                                |                   |     
|------------------------------- | ----------------- | ----
|                                | Average Occupancy
|Property                        | 2007              | 2006
|                                |                   |     
|Colony at Kenilworth Apartments | 96%               | 98% 
|Towson, Maryland                |                   |     



The Partnerships financial results depend upon a number of factors including the ability to attract and maintain tenants at the investment property, interest rates on mortgage loans, costs incurred to operate the investment property, general economic conditions and weather. As part of the ongoing business plan of the Partnership, the Managing General Partner monitors the rental market environment of the investment property to assess the feasibility of increasing rents, maintaining or increasing occupancy levels and protecting the Partnership from increases in expenses. As part of this plan, the Managing General Partner attempts to protect the Partnership from the burden of inflation-related increases in expenses by increasing rents and maintaining a high overall occupancy level. However, the Managing General Partner may use rental concessions and rental rate reductions to offset softening market conditions, accordingly, there is no guarantee that the Managing General Partner will be able to sustain such a plan. Further, a number of factors that are outside the control of the Partnership such as the local economic climate and weather can adversely or positively affect the Partnerships financial results.



Results of Operations



The Partnerships net income for the three months ended March 31, 2007 and 2006 was approximately $211,000 and $10,413,000, respectively.  The decrease in net income is primarily due to the recognition of a gain on sale of discontinued operations in 2006.



On March 31, 2006, the Partnership sold Place du Plantier Apartments to a third party, for net proceeds of approximately $9,207,000 after a deduction for immediate capital needs, a prepayment penalty and payment of closing costs.  The Partnership used approximately $5,694,000 of the net proceeds to repay the mortgage encumbering the property.   The Partnership realized a gain of approximately $7,926,000 during the three months ended March 31, 2006 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $1,277,000 as a result of unamortized loan costs written off and payment of a prepayment penalty.  This amount is included in loss from discontinued operations. Also included in loss from discontinued operations for the three months ended March 31, 2006 is approximately $150,000 of income, including revenues of approximately $501,000.



On March 31, 2006, the Partnership sold Fairway View I Apartments to a third party, for net proceeds of approximately $7,157,000 after a deduction for immediate capital needs, a prepayment penalty owed by the Partnership and payment of closing costs.  The Partnership used approximately $4,610,000 of the net proceeds to repay the mortgage encumbering the property. The Partnership realized a gain of approximately $4,514,000 as a result of the sale.  In addition, the Partnership recorded a loss on early extinguishment of debt of approximately $1,016,000 as a result of unamortized loan costs written off and payment of a prepayment penalty.  This amount is included in loss from discontinued operations. Also included in loss from discontinued operations for the three months ended March 31, 2006 is approximately $72,000 of income, including revenues of approximately $435,000.



Excluding the discontinued operations and the gain on sale of discontinued operations, the Partnership realized income from continuing operations of approximately $211,000 and $44,000 for the three months ended March 31, 2007 and 2006, respectively.  The increase in income from continuing operations is due to an increase in total revenues and a decrease in total expenses.  The increase in total revenues is due to increases in rental and other income and the recognition of a casualty gain in 2007.  Rental income increased due to an increase in the average rental rate partially offset by a decrease in occupancy at Colony at Kenilworth Apartments.  Other income increased due to increases in lease cancellation fees and application fees at Colony at Kenilworth Apartments and due to an increase in interest income due to higher cash balances maintained in interest bearing accounts.



During March 2006, the Partnerships investment property, Colony at Kenilworth Apartments, incurred damage as a result of a fire. During the year ended December 31, 2006, the Partnership recognized a casualty gain of approximately $82,000, which is the result of insurance proceeds received of approximately $82,000, as the damaged assets were fully depreciated.  During the three months ended March 31, 2007, the Partnership recognized an additional casualty gain related to this event of approximately $23,000, which is the result of additional insurance proceeds received of approximately $23,000.



Total expenses decreased due to decreases in interest, property tax and general and administrative expenses partially offset by an increase in depreciation expense.  Operating expenses remained comparable for both periods.  Interest expense decreased due to a decrease in mortgage interest at Colony at Kenilworth Apartments as a result of scheduled principal payments that reduced the carrying amount of the mortgage and a decrease in interest on advances from an affiliate of the Managing General Partner due to the repayment of the advances in 2006.  Property taxes decreased due to a decrease in the assessed value of Colony at Kenilworth Apartments.  Depreciation expense increased due to property improvements and replacements placed into service during the past twelve months at Colony at Kenilworth Apartments.



General and administrative expenses decreased for the three months ended March 31, 2007 primarily due to a decrease in management reimbursements to an affiliate of the Managing General Partner as allowed under the Partnership Agreement. Also included in general and administrative expenses for the three months ended March 31, 2007 and 2006 are costs associated with the quarterly and annual communications with investors and regulatory agencies.



Liquidity and Capital Resources



At March 31, 2007, the Partnership had cash and cash equivalents of approximately $653,000 compared to approximately $6,582,000 at March 31, 2006.  Cash and cash equivalents decreased approximately $48,000 from December 31, 2006 due to approximately $216,000 and $117,000 of cash used in investing and financing activities, respectively, partially offset by approximately $285,000 of cash provided by operating activities.  Cash used in investing activities consisted of property improvements and replacements partially offset by insurance proceeds received.  Cash used in financing activities consisted of principal payments on the mortgage encumbering the Partnerships investment property.  The Partnership invests its working capital reserves in interest bearing accounts.



NPI Equity, on behalf of the Partnership and certain affiliated partnerships, has established a revolving credit facility (the "Partnership Revolver") to be used to fund deferred maintenance and working capital needs of the Partnership and certain other affiliated partnerships in the National Property Investors Partnership Series. The maximum draw available to the Partnership under the Partnership Revolver is $500,000. Loans under the Partnership Revolver will have a term of 365 days, be unsecured and will bear interest at the prime rate plus 2% per annum (10.25% at March 31, 2007). The maturity date of any such borrowing accelerates in the event of: (i) the removal of NPI Equity as the managing general partner (whether or not for Cause); (ii) the sale or refinancing of a property by the Partnership (whether or not a borrowing under the Partnership Revolver was made with respect to such property); or (iii) the liquidation of the Partnership. During the three months ended March 31, 2006, an affiliate of the Managing General Partner advanced the Partnership approximately $290,000 to pay outstanding accounts payable at Fairway View I and Colony at Kenilworth Apartments and capital improvements at all three properties. There were no such advances during the three months ended March 31, 2007.  Interest expense for the three months ended March 31, 2006 was approximately $59,000.  During 2006, the Partnership repaid approximately $2,651,000 of advances and accrued interest.



The sufficiency of existing liquid assets to meet future liquidity and capital expenditure requirements is directly related to the level of capital expenditures required at the investment property to adequately maintain the physical asset and other operating needs of the Partnership and to comply with Federal, state, and local legal and regulatory requirements. The Managing General Partner monitors developments in the area of legal and regulatory compliance.  For example, the Sarbanes-Oxley Act of 2002 mandates or suggests additional compliance measures with regard to governance, disclosure, audit and other areas. In light of these changes, the Partnership expects that it will incur higher expenses related to compliance.  Capital improvements planned for the Partnerships property are detailed below.



Colony at Kenilworth Apartments



During the three months ended March 31, 2007, the Partnership completed approximately $130,000 of capital improvements at Colony at Kenilworth Apartments, consisting primarily of exterior doors, fire safety equipment, golf carts, and appliance, roof, and floor covering replacements. These improvements were funded from operating cash flow and insurance proceeds. The Partnership regularly evaluates the capital improvement needs of the property.  While the Partnership has no material commitments for property improvements and replacements, certain routine capital expenditures are anticipated during 2007.  Such capital expenditures will depend on the physical condition of the property as well as anticipated cash flow generated by the property.



Capital expenditures will be incurred only if cash is available from operations or from Partnership reserves.  To the extent that capital improvements are completed, the Partnership's distributable cash flow, if any, may be adversely affected at least in the short term.



The Partnership's assets are thought to be sufficient for any near-term needs (exclusive of capital improvements) of the Partnership. The mortgage indebtedness encumbering the Partnership's property of approximately $12,221,000 is being amortized over 240 months and is scheduled to be fully amortized at maturity in 2021.



There were no distributions during the three months ended March 31, 2007 and 2006. Future cash distributions will depend on the levels of net cash generated from operations and the timing of the property sale and/or refinancing. The Partnership's cash available for distribution is reviewed on a monthly basis. There can be no assurance that the Partnership will generate sufficient funds from operations, after required capital expenditures, to permit any distributions to its partners in 2007.



Other



In addition to its indirect ownership of the Managing General Partner interest in the Partnership, AIMCO and its affiliates owned 76,596 limited partnership units (the "Units") in the Partnership representing 69.89% 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. It is possible that AIMCO or its affiliates will acquire additional Units in exchange for cash or a combination of cash and units in AIMCO Properties, L.P., the operating partnership of AIMCO, either through private purchases or tender offers. 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 Managing General Partner. As a result of its ownership of 69.89% 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 46,289 Units acquired on January 19, 1996, 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 Managing General Partner or to its affiliates; and (ii) on all other matters submitted by it or its affiliates, in proportion to the vote 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 Managing General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner also owes fiduciary duties to AIMCO as its sole stockholder. As a result, the duties of the Managing General Partner, as Managing General Partner, to the Partnership and its limited partners may come into conflict with the duties of the Managing General Partner to AIMCO as its sole stockholder.



Critical Accounting Policies and Estimates



The financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require the Partnership to make estimates and assumptions. The Partnership believes that of its significant accounting policies, the following may involve a higher degree of judgment and complexity.



Impairment of Long-Lived Asset



Investment property is recorded at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable.  If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnerships estimate of the undiscounted future cash flows, excluding interest charges, of the property.   If the carrying amount exceeds the aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.



Real property investment is subject to varying degrees of risk.  Several factors may adversely affect the economic performance and value of the Partnerships investment property.  These factors include, but are not limited to, general economic climate; competition from other apartment communities and other housing options; local conditions, such as loss of jobs or an increase in the supply of apartments that might adversely affect apartment occupancy or rental rates; changes in governmental regulations and the related cost of compliance; increases in operating costs (including real estate taxes) due to inflation and other factors, which may not be offset by increased rents; and changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multi-family housing.  Any adverse changes in these factors could cause impairment of the Partnerships asset.



Revenue Recognition



The Partnership generally leases apartment units for twelve-month terms or less.  The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area.  Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease.  The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current tenants and all receivables due from former tenants.



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.











PART II - OTHER INFORMATION





ITEM 1.

LEGAL PROCEEDINGS



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 ManagingGeneral 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 financial condition or results of operations.
