We have audited the accompanying Combined Historical Summary of Gross Income and Direct Operating Expenses of the Dreyfuss Apartment Communities (the "Communities") as described in Note 1 for the year ended December 31, 1998. This Combined Historical Summary is the responsibility of the Communities' management. Our responsibility is to express an opinion on this Combined Historical Summary based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Combined Historical Summary is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the Combined Historical Summary. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the Combined Historical Summary. We believe that our audit provides a reasonable basis for our opinion. The Combined Historical Summary has been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission for inclusion in the Current Report on Form 8-K of AIMCO Properties, L.P., as described in Note 1, and is not intended to be a complete presentation of the income and expenses of the Communities. In our opinion, the Combined Historical Summary referred to above presents fairly, in all material respects, the gross income and direct operating expenses of the Dreyfuss Apartment Communities, as described in Note 1, for the year ended December 31, 1998, in conformity with accounting principles generally accepted in the United States. /s/ ERNST & YOUNG LLP Denver, Colorado October 8, 1999 1 2 Dreyfuss Apartment Communities Combined Historical Summary of Gross Income and Direct Operating Expenses NINE MONTHS YEAR ENDED ENDED DECEMBER 31, SEPTEMBER 30, 1998 1999 ------------- ------------- (unaudited) GROSS INCOME Rental income $ 17,157,910 $ 13,458,968 Other income 456,564 336,807 ------------- ------------- Total gross income 17,614,474 13,795,775 DIRECT OPERATING EXPENSES Repairs and maintenance 1,458,278 1,055,680 Utilities and other property operating 1,583,070 1,244,916 General and administrative 2,720,227 1,989,925 Real estate taxes 1,151,069 960,736 Management fees 724,115 576,577 ------------- ------------- Total direct operating expenses 7,636,759 5,827,834 ------------- ------------- Excess of gross income over direct operating expenses $ 9,977,715 $ 7,967,941 ============= ============= See accompanying notes. 2 3 Dreyfuss Apartment Communities Notes to Combined Historical Summary of Gross Income and Direct Operating Expenses Year Ended December 31, 1998 and Nine Months Ended September 30, 1999 (unaudited) 1.

The accompanying Combined Historical Summary has been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission for inclusion in the Current Report on Form 8-K of AIMCO Properties, L.P. The Combined Historical Summary is not intended to be a complete presentation of income and expenses of the Communities for the year ended December 31, 1998 and the nine months ended September 30, 1999, as certain costs such as depreciation, amortization, interest, and other debt service costs have been excluded. These costs are not considered to be direct operating expenses. 3 4 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES The preparation of the Combined Historical Summary in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts included in the Combined Historical Summary and accompanying notes thereto. Actual results could differ from those estimates. REVENUE RECOGNITION Rental income attributable to residential leases is recorded when due from residents. Leases are for periods of up to one year, with rental payments due monthly. INTERIM UNAUDITED FINANCIAL INFORMATION The accompanying interim unaudited Combined Historical Summary has been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and was prepared on the same basis as the Combined Historical Summary for the year ended December 31, 1998. In the opinion of management of the Communities, all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the information for this interim period have been made. The excess of combined gross income over direct operating expenses for such interim period is not necessarily indicative of the excess of gross income over direct operating expenses for the full year. 3. TRANSACTIONS WITH AFFILIATES Dreyfuss Brothers Inc. and Dreyfuss Management Services, Inc., affiliates, receive management fees relating to the Communities. The management fee ranges from 3.5% to 5.0% of gross annual cash receipts. 4
