Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Note 1 — Organization Apartment Investment and Management Company (“Aimco”), a Maryland corporation incorporated on January 10, 1994, is a self-administered and self-managed real estate investment trust (“REIT”). Aimco, through a wholly owned subsidiary, is the general and special limited partner of Aimco OP L.P. (“Aimco Operating Partnership”). Except as the context otherwise requires, “we,” “our,” and “us” refer to Aimco, Aimco Operating Partnership, and their consolidated subsidiaries, collectively. On December 15, 2020, Aimco completed the separation of its businesses (the “Separation”), creating two, separate and distinct, publicly traded companies, Aimco and Apartment Income REIT Corp. (“AIR”) (Aimco and AIR together, as they existed prior to the Separation, “Aimco Predecessor”). Events noted in this filing as occurring before December 15, 2020, were those entered into by Aimco Predecessor. Business As of September 30, 2022, Aimco owned 92.7 % of the legal interest in the common partnership units of Aimco Operating Partnership and 95.0 % of the economic interest in Aimco Operating Partnership. The remaining 7.3 % legal interest is owned by limited partners. As the sole general partner of Aimco Operating Partnership, Aimco has exclusive control of Aimco Operating Partnership’s day-to-day management. We own or lease a portfolio of real estate investments focused primarily on the U.S. multifamily sector. These real estate investments include: a portfolio of 26 operating apartment communities ( 22 consolidated properties with 5,640 apartment homes and four unconsolidated operating properties), diversified by both geography and price point; one commercial office building that is part of a land assemblage; two residential apartment communities, with 965 planned apartment homes, a single family rental community with 16 planned homes plus eight accessory dwelling units, and one hotel, with 106 planned rooms, we are actively developing or redeveloping; land parcels held for development. Our real estate portfolio also includes one land parcel held for sale and two unconsolidated investments in land held for development.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2 — Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. ("GAAP") have been condensed or omitted in accordance with such rules and regulations, although management believes the disclosures are adequate to prevent the information presented from being misleading. In the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The Condensed Consolidated Balance Sheets of Aimco and Aimco Operating Partnership as of December 31, 2021 have been derived from their respective audited financial statements at that date, but do not include all of the information and disclosures required by GAAP for complete financial statements. For further information, refer to the financial statements and notes thereto included in Aimco’s and Aimco Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2021 . Except where indicated, the footnotes refer to both Aimco and Aimco Operating Partnership. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Aimco, Aimco Operating Partnership, and their consolidated subsidiaries. Aimco Operating Partnership’s condensed consolidated financial statements include the accounts of Aimco Operating Partnership and its consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. We consolidate a variable interest entity (“VIE”) in which we are considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. As used herein, and except where the context otherwise requires, “partnership” refers to a limited partnership or a limited liability company and “partner” refers to a partner in a limited partnership or a member of a limited liability company. Certain reclassifications have been made to prior period amounts to conform to the current period condensed consolidated financial statement presentation with no effect on the Company’s previously reported results of operations, financial position, or cash flows. Common Noncontrolling Interests in Aimco Operating Partnership Common noncontrolling interests in Aimco Operating Partnership consist of common Aimco Operating Partnership Units (“OP Units”), and are reflected in Aimco’s accompanying Condensed Consolidated Balance Sheets as Common Noncontrolling Interests in Aimco Operating Partnership . Aimco Operating Partnership’s income or loss is allocated to the holders of common OP Units, other than Aimco, based on the weighted-average number of common OP Units (including Aimco) outstanding during the period. For all periods presented, the holders of common OP Units had a weighted-average economic ownership interest in Aimco Operating Partnership of approximately 5.0 % . Substantially all of the assets and liabilities of Aimco are held by Aimco Operating Partnership. Redeemable Noncontrolling Interests in Consolidated Real Estate Partnerships Redeemable noncontrolling interests consist of equity interests held by a limited partner in a consolidated real estate partnership that has a finite life. If a consolidated real estate partnership includes redemption rights that are not within our control, the noncontrolling interest is included as temporary equity. The assets of these consolidated real estate partnerships must first be used to settle the liabilities of the consolidated real estate partnerships. The consolidated real estate partnerships' creditors do not have recourse to the general credit of Aimco Operating Partnership. In July 2022, we closed a $ 102.0 million preferred equity financing with an institutional investor, providing for a fixed 8 % annual rate of return payable monthly. In February 2022, we acquired all of the outstanding redeemable noncontrolling interests in two consolidated properties for $ 5.1 million. At the time of redemption, the carrying amount of the redeemable non-controlling interests was $ 4.9 million. Redeemable noncontrolling interests in consolidated real estate partnerships as of September 30, 2022 consists of the $ 102.0 million preferred equity noted above and our partner's equity interest in the Upton Joint Venture, which provides for an accruing 9.7 % rate of return on their investment. These investment interests are presented as Redeemable noncontrolling interests in consolidated real estate partnerships in our Condensed Consolidated Balance Sheet as of September 30, 2022. The following table shows changes in our redeemable noncontrolling interests in consolidated real estate partnerships from December 31, 2021 to September 30, 2022 (in thousands): Balance at December 31, 2021 $ 33,794 Capital contributions 124,723 Distributions ( 917 ) Redemptions ( 4,911 ) Net income 5,446 Balance at September 30, 2022 $ 158,135 Mezzanine Investment In November 2019, Aimco Predecessor made a five-year , $ 275.0 million mezzanine loan to the partnership owning the “Parkmerced Apartments” located in southwest San Francisco (the “Mezzanine Investment”). The loan bears interest at a 10 % annual rate, accruing if not paid from property operations. Ownership of the subsidiaries that originated and hold the mezzanine loan was retained by AIR following the Separation. The Separation Agreement provides for AIR to transfer ownership of the subsidiaries that originated and hold the mezzanine loan, a related equity option to acquire a 30 % interest in the partnership owning Parkmerced Apartments and the interest rate option, or swaption, that provides partial protection against future refinancing risk to Aimco through 2024 once required third-party consents are received . At the time of the Separation and as of the date of this filing, legal title of these subsidiaries had not yet transferred to Aimco. Until legal title of the subsidiaries is transferred, AIR is obligated to pass payments received on such loan to us, and we are obligated to indemnify AIR against any costs and expenses related thereto. We have the risks and rewards of ownership of the Mezzanine Investment and have recognized an asset related to our right to receive the Mezzanine Investment from AIR. We recognize as income the net amounts recognized by AIR on its equity investment that are due to be paid to us when collected to the extent the income is supported by the change in AIR's claim to the net assets of the underlying borrower. The income recognized primarily represents the interest accrued under the terms of the underlying mezzanine loan. The loan and the underlying real estate are subject to certain risks, including, but not limited to, those resulting from the lingering disruption due to the COVID-19 pandemic and associated response, and any similar events that might occur in the future, which may result in all or a portion of the loan not being repaid. In the event we conclude that a portion of the Mezzanine Investment is not recoverable, we will recognize an impairment . Income Tax Benefit (Expense) Certain aspects of our operations, including our development and redevelopment activities, are conducted through taxable REIT subsidiaries, or TRS entities. Additionally, our TRS entities hold investments in one of our apartment communities and 1001 Brickell Bay Drive. Our income tax benefit calculated in accordance with GAAP includes income taxes associated with the income or loss of our TRS entities. Income taxes, as well as changes in valuation allowance and incremental deferred tax items in conjunction with intercompany asset transfers and internal restructurings (if applicable), are included in Income tax benefit (expense) in our Condensed Consolidated Statements of Operations . Consolidated GAAP income or loss subject to tax consists of pretax income or loss of our taxable entities and gains retained by the REIT. For the three and nine months ended September 30, 2022 , we had consolidated net loss and income subject to tax of $ 75.6 million and $ 91.0 million, respectively. For the three and nine months ended September 30, 2021 , we had consolidated net losses subject to tax of $ 7.9 million and $ 26.4 million, respectively. For the three months ended September 30, 2022, we recognized income tax benefit of $ 17.6 million compared to a $ 2.0 million benefit during the same period in 2021. The change is primarily due to the GAAP income taxes associated with the lease modification depreciation expense recognized in the third quarter of 2022. For the nine months ended September 30, 2022, we recognized income tax expense of $ 24.3 million compared to a $ 9.9 million benefit during the same period in 2021 . The change is primarily due to the GAAP income taxes associated with the net lease modification income recognized in 2022. Use of Estimates The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts included in the financial statements and accompanying notes thereto. Actual results could differ from those estimates. Cash Equivalents We classify highly liquid investments with an original maturity of three months or less as cash equivalents. We maintain cash equivalents in financial institutions in excess of insured limits. We have not experienced any losses in these accounts in the past and believe that we are not exposed to significant credit risk because our accounts are deposited with major financial institutions. Restricted Cash Restricted cash consists of tenant security deposits, capital replacement reserves, insurance reserves, and cash restricted as required by our debt agreements. Other Assets, net Other assets were comprised of the following amounts (in thousands): September 30, 2022 December 31, 2021 Other investments $ 63,594 $ 45,386 Notes receivable 38,759 38,029 Unconsolidated real estate partnerships 28,958 13,025 Assets held for sale (1) 11,735 — Deferred costs, deposits, and other 11,667 22,136 Prepaid expenses and real estate taxes 10,489 20,516 Corporate fixed assets 8,484 9,855 Accounts receivable, net of allowances of $ 1,406 and $ 1,285 as of September 30, 2022 and December 31, 2021, respectively 2,544 2,469 Deferred tax assets 1,999 6,388 Intangible assets, net 1,176 3,269 Due from affiliates 1,236 4,840 Total other assets, net $ 180,641 $ 165,913 (1) In addition to the properties we sold during the period, from time to time we may market to sell certain properties that are inconsistent with our long-term investment strategy. At the end of each reporting period, we evaluate whether such properties meet the criteria to be classified as held for sale. As of September 30, 2022 , assets held for sale include one land parcel in Fort Lauderdale, Florida, which is expected to be sold during the fourth quarter of 2022. Accounting Pronouncements Adopted in the Current Year During the quarter ended March 31, 2022, we adopted ASU 2021-05 establishing Topic 842, Lessors - Certain Leases with Variable Lease Payments . ASU 2021-05 requires a lessor to classify a lease with variable payments that do not depend on an index or rate as an operating lease if either a sales-type lease or direct finance lease classification would trigger a day-one loss. The adoption of this standard on January 1, 2022 , did not have a material impact on our condensed consolidated financial statements. Recent Accounting Pronouncements In March 2020, the FASB issued Accounting Standards Update No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the LIBOR or by another reference rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued Accounting Standards Update 2021-01 , “Reference Rate Reform (Topic 848): Scope” (“ASU 2021-01”), which clarified the scope and application of the original guidance. We plan to adopt ASU 2020-04 and ASU 2021-01 when LIBOR is discontinued. We are currently evaluating the potential impact of adopting this guidance, but do not expect it to have a material impact on our co nsolidated financial statements due to the fact that we hold one month LIBOR debt instruments, which are not expected to be discontinued in 2022.

Significant Transactions [Abstract]
Significant Transactions	Note 3 —Significant Transactions Acquisitions and Investments • In February 2022, we entered into a short-term cancellable lease of and a purchase agreement to acquire, for $ 100.0 million, a nine -acre development site in the Flagler Village neighborhood of Fort Lauderdale, Florida. The site has the potential for the development of approximately three million square feet of mixed-use property, which could contain up to 1,500 residential units at full build-out. As of September 30, 2022, we had completed the $ 100.0 million purchase and recognized an additional $ 5.9 million of capitalized costs to Land in our Condensed Consolidated Balance Sheets. • In January 2022, our Fort Lauderdale consolidated joint venture closed on the acquisition of three undeveloped land parcels located in downtown Fort Lauderdale, Florida for $ 49.0 million ($ 25.0 million at Aimco's 51 % share), funded primarily by a $ 40.0 million land loan ($ 20.4 million at Aimco's share). The cost was allocated among the parcels based on third-party appraisals. At the time of acquisition, one land parcel was subject to a sales agreement with closing expected during the fourth quarter of 2022. Based on the facts and circumstances related to the sale, we determined the land parcel met the criteria for classification as assets held for sale as of September 30, 2022. These assets are reported at a carrying value of $ 11.7 million, and are included within Other assets, net in our Condensed Consolidated Balance Sheets . Liabilities related to these assets held for sale of $ 8.1 m illion are included in Accrued liabilities and other in our Condensed Consolidated Balance Sheets . • In February 2022, we funded the remaining $ 14.2 million of a total $ 50.0 million commitment of a passive equity investment in IQHQ Inc. (IQHQ), a privately held life sciences real estate development company. Based on certain facts and circumstances related to the investment, IQHQ was initially reported at cost. In June 2022, 22 % of our original investment with a cost basis of $ 10.8 million was redeemed for $ 16.5 million. Consequently, we recognized a $ 5.7 million gain from this redemption, and the redemption cash was received in July 2022. Further at that time, our remaining investment in IQHQ with a cost basis of $ 39.2 million was valued at an estimated fair market value of $ 59.7 million, and a $ 20.5 million unrealized gain was recognized . Joint Venture Transactions • In May 2022, we formed two joint ventures for a ground up project on the development of a phased multifamily community totaling 574 units in Bethesda, Maryland. We hold a 50 % share of the joint ventures (the “DC joint ventures”), with a maximum total initial capital commitment of $ 21.6 million, of which $ 13.4 milli on has been funded as of September 30, 2022. We serve as co-development manager for these ventures, which are expected to begin construction in late 2023. • In March 2022, we formed a joint venture for the construction of approximately one million square feet of mixed-use development in the Edgewater neighborhood of Miami, Florida. We hold a 20 % share of the joint venture ( the “Edgewater joint venture"), which includes our initial contribution of an eighth of an acre of land that we purchased for $ 1.7 million in January 2022 and cash of $ 0.3 million. Our total capital commitment for this venture i s $ 8.0 million. We will serve as the development manager for this project, which is expected to begin construction in 2023. Dispositions • In July, we sold Cedar Rim, a 104 -unit apartment community located in Renton, Washington, for $ 53.0 million. Cedar Rim was previously reported as held for sale. • In August, we sold 2900 on First, a 135 -unit apartment community with 14,000 square feet of retail located in Seattle, Washington for $ 69.0 million. 2900 on First was previously reported as held for sale. • In May 2022, we closed on the sale of our Pathfinder Village property located in Fremont, California, for a gross sales price of $ 127.0 million and recognized a gain of $ 94.6 million. Pathfinder Village was a stabilized property previously reported within our Operating segment. Lease Arrangements • In September 2022, we as lessee, received final payment from AIR, pursuant to the lease termination agreement entered into in June 2022. The leases with respect to four properties were terminated, and we relinquished control of these properties. See Note 9 for further information .

Related Party Transactions [Abstract]
Agreements and Transactions With AIR	Note 5 — Agreements and Transactions With AIR In conjunction with the Separation in December 2020, we entered into the following agreements with AIR that have significant operational and financial impacts to us. Master Services Agreement Under the Master Services Agreement with AIR, AIR provides us with customary administrative and support services. We are obligated to pay AIR the fully burdened costs in performing those services. We may terminate any or all services on 60 days’ prior written notice, and AIR may terminate individual services at any time after December 31, 2023. During the three and nine months ended September 30, 2022, we incurred administrative and supp ort fees of $ 0.6 million and $ 1.5 million, respectively, compared to $ 0.7 million and $ 1.8 million during the three and nine months ended September 30, 2021, respectively. These administrative support fees are included in General and administrative expenses in our Condensed Consolidated Statements of Operations . Property Management Agreements Under the Property Management Agreements with AIR, AIR provides us with certain property management, property accounting and related services for the majority of our operating properties. We pay AIR a property management fee equal to 3 % of each respective property’s revenue collected and such other fees as may be mutually agreed upon for various other services. The initial term of each Property Management Agreement is one year, with automatic one-year renewal periods, unless either party elects to terminate upon delivery of 60 days’ prior written notice to the other party before the end of the term. Neither party is obligated to pay a termination fee or other penalty upon such termination. During the three and nine months ended September 30, 2022, we incurred property management and property accounting fees of $ 1.4 million and $ 4.1 million , respectively, compared to $ 1.3 million and $ 3.8 million during the three and nine months ended September 30, 2021, respectively. These fees are included in Property operating expenses in our Condensed Consolidated Statements of Operations . Master Leasing Agreement The Master Leasing Agreement, as amended on June 14, 2022, governs the current and any future leasing arrangements between us, as lessee, and AIR, as lessor. Under the amendments to the Master Leasing Agreement, AIR's purchase option to acquire completed development and redevelopment properties was replaced with a right of first offer on development and redevelopment assets that have achieved stabilization and that we choose to bring to market within one year thereafter. Each time the parties wish to execute a new lease for a particular property, they will execute a stand-alone lease. In September 2022, we received final payment from AIR, pursuant to the lease termination agreement entered into in June 2022. The leases with respect to four properties were terminated, and we relinquished control of the associated properties. See Note 9 for further information. Notes Payable to AIR In July 2022, we completed the prepayment of the $ 534.1 million of Notes Payable to AIR. As a result of the prepayment, we incurred $ 17.4 million of spread maintenance costs, which were fully accrued as of June 30, 2022. For the three and nine months ended September 30, 2022 , we recognized interest expense on the Notes Payable to AIR of $ 0.4 million and $ 13.7 million, respectively, compared to $ 6.9 million and $ 20.8 million for the three and nine months ended September 30, 2021, respectively. Other In June 2022, for $ 7.2 million, we acquired from AIR the common noncontrolling interest in the entity that indirectly holds a portfolio of assets that previously secured the Notes Payable to AIR. Due to and from AIR As of September 30, 2022, we have amounts due to and from AIR of $ 6.7 m illion and $ 1.0 million, respectively. As of December 31, 2021 we had amounts due to and from AIR of $ 15.7 million and $ 4.8 million, respectively. The amounts due to AIR primarily consist of invoices paid on our behalf and other reimbursements owed to AIR. The amounts due from AIR primarily consist of net cash flows generated by our operating properties. Terry Considine Service Agreement/AIR Reimbursement As contemplated by the Separation and by Aimco and AIR, Terry Considine, an Aimco board member and our former Chief Executive Officer, has specific responsibilities to us as a non-executive employee during 2022 to support the establishment and growth of our business, reporting directly to our board of directors (the "Board"). These responsibilities, separate from Mr. Considine’s services as a board member, include: (i) short and long-term strategic direction and advice; (ii) transition and executive support to officers; and (iii) advice and consultation with respect to strategic growth and acquisition activities. The independent directors of the Board set Mr. Considine’s 2022 target total compensation (including base compensation, short-term incentive, and long-term incentive) for these responsibilities at $ 2.1 million, to be paid in equity. Mr. Considine does not receive any additional compensation for serving on the Board. Additionally, we are obligated for all base salary, short-term incentive amounts and long-term incentive amounts payable to Mr. Considine for the calendar year 2022 under the terms of his employment agreement with AIR that are in excess of $ 1.0 million, collectively. As of September 30, 2022, we estimate the total 2022 reimbursement to AIR, pursuant to this arrangement, will b e $ 4.5 m illion. We estimate compensation associated with these arrangements to tota l $ 6.6 million for 2022. For the three and nine months ended September 30, 2022, we recognized $ 1.7 million and $ 4.6 million of expense related to the arrangements, respectively, compared to $ 1.2 million and $ 4.1 million for the three and nine months ended September 30, 2021, respectively. This expense is included in General and administrative expenses in our Condensed Consolidated Statements of Operations .

Earnings Per Share [Abstract]
Earnings and Dividends per Share and per Unit	Note 6 — Earnings and Dividends per Share and per Unit Aimco and Aimco Operating Partnership calculate basic earnings per share of common stock and basic earnings per common unit based on the weighted-average number of shares of common stock and common partnership units outstanding. We calculate diluted earnings per share of common stock and diluted earnings per common unit taking into consideration dilutive shares of common stock and common partnership unit equivalents and dilutive convertible securities outstanding during the period. Each of our executives and AIR’s executives received one unvested share of Aimco stock and one unvested share of AIR stock at the Separation date for each unvested share they held at that date. We include AIR’s executives’ rights to receive Aimco shares upon vesting in our dilutive calculations. Our common stock and common partnership unit equivalents include options to purchase shares of common stock, which, if exercised, would result in Aimco’s issuance of additional shares of common stock and Aimco Operating Partnership’s issuance to Aimco of additional common partnership units equal to the number of shares of common stock purchased under the options. These equivalents also include unvested performance-based restricted stock awards that do not meet the definition of participating securities, which would result in an increase in the number of shares of common stock and common partnership units outstanding equal to the number of the shares that vest. Common partnership unit equivalents also include unvested long-term incentive partnership units. We include in the denominator securities with dilutive effect in calculating diluted earnings per share and per unit during these periods. Our time-based restricted stock awards receive non-forfeitable dividends similar to shares of common stock and common partnership units prior to vesting, and our Performance-Based LTIP I units and Performance-Based LTIP II units receive non-forfeitable distributions based on specified percentages of the distributions paid to common partnership units prior to vesting and conversion. The unvested restricted shares and units related to these awards are participating securities. We include the effect of participating securities in basic and diluted earnings per share and unit computations using the two-class method of allocating distributed and undistributed earnings when the two-class method is more dilutive than the treasury stock method. Participating securities are included in the computation of diluted earnings per share for the three and nine months ended September 30, 2022 and 2021, because their effects are dilutive. Reconciliations of the numerator and denominator in the calculations of basic and diluted earnings per share and per unit for the three and nine months ended September 30, 2022 and 2021, are as follows (in thousands, except per share and per unit data): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Earnings per share Numerator: Net income (loss) attributable to Aimco $ 29,472 $ ( 5,016 ) $ 276,817 $ ( 4,492 ) Net income (loss) allocated to Aimco participating securities ( 405 ) — ( 3,806 ) — Net income (loss) attributable to Aimco common stockholders 29,067 ( 5,016 ) 273,011 ( 4,492 ) Denominator - shares: Basic weighted-average common stock outstanding 149,611 149,762 149,706 149,517 Diluted share equivalents outstanding 1,586 — 1,370 — Diluted weighted-average common stock outstanding 151,197 149,762 151,076 149,517 Earnings (loss) per share - basic $ 0.19 $ ( 0.03 ) $ 1.82 $ ( 0.03 ) Earnings (loss) per share - diluted $ 0.19 $ ( 0.03 ) $ 1.81 $ ( 0.03 ) Earnings per unit Numerator: Net income (loss) attributable to Aimco Operating Partnership $ 31,026 $ ( 5,269 ) $ 291,465 $ ( 4,701 ) Net income (loss) allocated to Aimco Operating Partnership participating securities ( 421 ) — ( 3,964 ) — Net income (loss) attributable to Aimco Operating Partnership's common unit holders 30,605 ( 5,269 ) 287,501 ( 4,701 ) Denominator - units Basic weighted-average common partnership units outstanding 157,530 157,806 157,627 157,873 Diluted partnership unit equivalents outstanding 1,606 - 1,390 - Diluted weighted-average common partnership units outstanding 159,136 157,806 159,017 157,873 Earnings (loss) per unit - basic $ 0.19 $ ( 0.03 ) $ 1.82 $ ( 0.03 ) Earnings (loss) per unit - diluted $ 0.19 $ ( 0.03 ) $ 1.81 $ ( 0.03 )

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7 — Fair Value Measurements Recurring Fair Value Measurements From time to time we purchase interest rate swaps, caps, and other instruments to provide protection against increases in interest rates on our variable rate debt. As of September 30, 2022, we held interest rate swaps and caps with $ 1.7 billion notional value that provide protection through the fourth quarter of 2024. These instruments were acquired for $ 15.7 million. The fair value of these instruments is noted in the table below. During the nine months ended September 30, 2022 , we monetized an interest rate swap and a portion of an interest rate cap for $ 15.5 million and recognized gains of $ 9.8 million, net of transaction costs. On a recurring basis, we measure at fair value our interest rate options, which are presented in Other assets, net in our Condensed Consolidated Balance Sheets . Our interest rate options are classified within Level 2 of the GAAP fair value hierarchy, and we estimate their fair value using pricing models that rely on observable market information, including contractual terms, market prices, and interest rate yield curves. The fair value adjustment is included in earnings in Unrealized gains on interest rate options in our Condensed Consolidated Statements of Operations . Changes in fair value are reflected as a non-cash transaction in adjustments to arrive at cash flows from operations, and any upfront premium is reflected in Purchase of interest rate options in our Condensed Consolidated Statements of Cash Flows . As of September 30, 2022, we have investments of $ 3.9 million in property technology funds consisting of entities that develop technology for the real estate industry. These investments are measured at net asset value (“NAV”) as a practical expedient. See Note 4 for further information. The following table summarizes fair value for our interest rate options and our investments in real estate technology funds as of September 30, 2022, and December 31, 2021 (in thousands): As of September 30, 2022 As of December 31, 2021 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Interest rate options $ 61,329 $ — $ 61,329 $ — $ 25,449 $ — $ 25,449 $ — Investment in real estate technology funds (1) $ 3,909 — — — $ 9,613 — — — (1) Investments measured at fair value using NAV as a practical expedient are not classified in the fair value hierarchy. Nonrecurring Fair Value Measurements As of September 30, 2022, assets measured at fair value on a nonrecurring basis shown in our Condensed Consolidated Balance Sheets consisted of our investment in IQHQ. IQHQ was initially reported at cost. In June 2022, 22 % of our original investment with a cost basis of $ 10.8 million was redeemed for $ 16.5 million . As a result, our remaining shares in IQHQ after the partial redemption were re-valued on a stepped up basis to fair value at the same per share value as the cash redemption per share value. These observable inputs are classified as Level 1 within the GAAP fair value hierarchy. As of September 30, 2022 , the fair value of our investment in IQHQ measured on a nonrecurring basis remained at $ 59.7 million. Fair Value Disclosures We believe that the carrying value of the consolidated amounts of cash and cash equivalents, restricted cash, accounts receivable and payables approximated their fair value as of September 30, 2022, and December 31, 2021 , due to their relatively short-term nature and high probability of realization. We estimate the fair value of our debt using an income and market approach, including comparison of the contractual terms to observable and unobservable inputs such as market interest rate risk spreads, contractual interest rates, remaining periods to maturity, debt service coverage ratios, and loan to value ratios. We classify the fair value of our non-recourse property debt and construction loans within Level 2 of the GAAP fair value hierarchy based on the significance of certain of the unobservable inputs used to estimate their fair value. As of July 2022, we had prepaid the $ 534.1 million of Notes Payable to AIR. The following table summarizes the carrying value and fair value of our non-recourse property debt, construction loans, and Notes Payable to AIR as of September 30, 2022, and December 31, 2021, (in thousands): As of September 30, 2022 As of December 31, 2021 Carrying Value Fair Value Carrying Value Fair Value Non-recourse property debt $ 868,237 $ 796,311 $ 484,883 $ 498,960 Construction loans 86,693 86,693 168,376 168,376 Notes Payable to AIR — — 534,127 534,127 Total $ 954,930 $ 883,004 $ 1,187,386 $ 1,201,463

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 8 — Variable Interest Entities We evaluate our investments in limited partnerships and similar entities in accordance with applicable consolidation guidance to determine whether each such entity is a VIE. The accounting standards for the consolidation of VIEs require qualitative assessments to determine whether we are the primary beneficiary. The primary beneficiary analysis is based on power and economics. We conclude that we are the primary beneficiary and consolidate the VIE if we have both: (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance, and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Significant judgments and assumptions related to these determinations include, but are not limited to, estimates about the current and future fair values and performance of real estate held by these VIEs and general market conditions. We consolidate Aimco Operating Partnership, a VIE of which Aimco is the primary beneficiary. Aimco, through Aimco Operating Partnership, consolidates all VIEs for which it is the primary beneficiary. Substantially all of the assets and liabilities of Aimco are that of Aimco Operating Partnership. Aimco Operating Partnership is the primary beneficiary, and therefore consolidates our four VIEs that own interests in real estate. In addition, we have nine unconsolidated VIEs for which we are not the primary beneficiary because we are not their primary decision maker. The nine unconsolidated VIEs include four unconsolidated real estate partnerships that hold four apartment communities in San Diego, California, the Mezzanine Investment, our passive equity investment in IQHQ, our investment in the Edgewater joint venture, and our investments in the DC joint ventures. Details of our consolidated and unconsolidated VIEs, excluding those of Aimco Operating Partnership, are summarized in the table below as of September 30, 2022, and December 31, 2021, (in thousands, except for VIE count): September 30, 2022 December 31, 2021 Consolidated Unconsolidated Consolidated Unconsolidated Count of VIEs 4 9 9 6 Assets Real estate, net $ 210,586 $ — $ 564,909 $ — Mezzanine investment — 362,788 — 337,797 Right-of-use lease assets 95,506 — 429,768 — Unconsolidated real estate partnerships — 28,958 — 13,005 Other assets, net — 59,686 43,715 35,773 Liabilities Deferred tax liabilities — — 124,747 — Accrued liabilities and other 25,515 — 30,519 — Non-recourse property debt, net 31,904 — — — Construction loans, net 12,237 — 163,570 — Lease liabilities 98,467 — 435,093 — Consolidated Real Estate Partnerships The changes in consolidated VIE assets and liabilities from December 31, 2021 to September 30, 2022 in the table above are primarily due to the impact of: (i) In September 2022, we as lessee received final payment from AIR as lessor, pursuant to the lease termination agreement entered into in June 2022. The leases with respect to four properties were terminated, and we relinquished control of the associated leasehold improvements and underlying land of these four properties. Consequently, we derecognized $ 86.6 million real estate assets and a $ 138.4 million construction loan was paid off and derecognized as well. In addition, we derecognized right-of-use lease assets and lease liabilities of $ 326.1 million and $ 337.3 million, respectively, due to the lease modifications described in Note 9. (ii) In February 2022, we acquired all of the outstanding redeemable non-controlling interests in an entity reported as a consolidated VIE as of December 31, 2021. Unconsolidated Real Estate Partnerships We own an interest in four unconsolidated real estate partnerships that hold four apartment communities in San Diego, California. We also own investments in the Edgewater joint venture formed in March 2022 to develop a 2.8-acre site in Miami's Edgewater neighborhood, and the DC joint ventures formed in May 2022 to develop a ground-up phased multifamily community in Bethesda, Maryland. See Note 3 for further information. Our investment balances of $ 29.0 million and $ 13.0 million as of September 30, 2022 and December 31, 2021, respectively, represented our maximum exposure to loss in these unconsolidated VIEs. Mezzanine Investment AIR owns an interest in a partnership that owns Parkmerced Apartments, of which it is not the primary beneficiary, and under the terms of the Separation Agreement, AIR is obligated to transfer ownership of the subsidiaries that hold this interest to us upon receipt of required third-party consents. Our investment balances of $ 362.8 million and $ 337.8 million as of September 30, 2022 and December 31, 2021, respectively, represent our indirect interest in notes receivable through our agreement with AIR and our maximum exposure to loss in this VIE.

Leases [Abstract]
Lease Arrangements	Note 9 — Lease Arrangements Aimco as Lessor The majority of lease payments we receive from our residents and tenants are fixed. We receive variable payments from our residents and commercial tenants primarily for utility reimbursements and other services. For the three and nine months ended September 30, 2022 and 2021, our total lease income was comprised of the following amounts for all residential and commercial property leases (in thousands): Three Months Ended September 30, Nine Months Ended 2022 2021 2022 2021 Fixed lease income $ 44,239 $ 39,382 $ 137,519 $ 113,726 Variable lease income 3,443 3,046 10,853 8,760 Total lease income $ 47,682 $ 42,428 $ 148,372 $ 122,486 Aimco as Lessee Lease Arrangements with AIR We, as lessee, and AIR, as lessor, have entered into leases on properties currently under construction or in lease-up. These lease arrangements are governed by separate Master Lease Agreements and the Master Leasing Agreement. In June 2022, we as lessee and AIR as lessor, entered into a lease termination agreement with respect to four leases entered into on January 1, 2021 that pertained to our North Tower of Flamingo Point, 707 Leahy, The Fremont, and Prism properties . This agreement terminated the four finance leases on September 1, 2022. Upon termination, both parties were released of any and all liabilities and obligations under each respective lease other than those liabilities and obligations, if any, that expressly survived termination. On September 1, 2022, we relinquished control of the leasehold improvements on these four properties as well as the underlying land. In exchange, AIR remitted a total o f $ 200.0 m illion in consideration to us as termination payments. Because the termination agreement modified the expiration date of each lease to September 1, 2022, we accelerated depreciation on the associated leasehold improvements using lease terms that ended September 1, 2022. We recorded $ 69.9 million and $ 85.7 million of total d epreciation expense for the three and nine months ended September 30, 2022, respectively. In addition, we recognized Lease modification income of $ 1.6 million and $ 207.0 million, which is included in our Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2022, respectively. Ground Leases We are lessee to two 99-year ground leases for the land underlying the development site at Upton Place, a mixed-use development project which will create 689 apartment homes and approximately 100,000 square feet of commercial space in upper-northwest Washington, D.C. These ground leases are classified as finance leases. Other Finance Lease Arrangements As described in Note 3 , in February 2022, we, as lessee, entered into certain finance lease arrangements concurrent with a purchase agreement to acquire a development site in the Flagler Village neighborhood of Fort Lauderdale, Florida. As of September 30, 2022, we had completed the $ 100.0 million purchase and recognized an additional $ 5.9 million of capitalized costs to Land in our Condensed Consolidated Balance Sheets. See Note 3 for additional information. As of September 30, 2022 and December 31, 2021, our finance leases had weighted-average remaining terms of 93.9 years and 38.5 years, respectively, and weighted-average discount rates of 6.0 % and 5.4 %, respectively. As of September 30, 2022 , finance lease right-of-use lease assets and liabilities totaled $ 95.5 million and $ 98.5 million, respectively. As of December 31, 2021 , finance right-of-use lease assets and liabilitie s totaled $ 429.8 million and $ 435.1 million, r espectively. For the three and nine months ended September 30, 2022, amortization related to finance leases was $ 0.0 million and $ 6.7 million, respectively, net of amounts capitalized, compared to $ 2.1 million and $ 5.5 million for the three and nine months ended September 30, 2021, respectively. For the three and nine months ended September 30, 2022, we capitalized $ 1.7 million and $ 6.5 million, respectively, of lease costs associated with active development and redevelopment projects on certain of the underlying property and ground lease assets, compared to $ 5.8 million and $ 18.5 m illion, respectively, for three and nine months ended September 30, 2021. Operating Lease Arrangements We have operating leases primarily for corporate office space. As of September 30, 2022 and December 31, 2021, our operating leases had weighted-average remaining terms of 6.6 years and 7.4 years, respectively. As of September 30, 2022 and December 31, 2021, the leases had weighted-average discount rates of 3.1 % , an d 3.1 %, re spectively. We record operating lease expense on a straight-line basis over the lease term. Total operating lease expense for the three and nine months ended September 30, 2022 wa s $ 0.2 million and $ 0.5 million, respectively, compared to $ 0.2 million and $ 0.5 million for the three and nine months ended September 30, 2021, respectively. As of September 30, 2022 and December 31, 2021, operating lease right-of-use lease assets of $ 4.6 million and $ 5.1 million, respectively, are included in O ther assets, net in our Condensed Consolidated Balance Sheets . As of September 30, 2022 and December 31, 2021, operating lease liabilities of $ 11.6 million and $ 12.7 m illion, respectively, are included in A ccrued liabilities and other in our Condensed Consolidated Balance Sheets . For finance and operating leases, when the rate implicit in the lease cannot be determined, we estimate the value of our lease liabilities using discount rates equivalent to the rates we would pay on a secured borrowing with terms similar to the leases. We determine if an arrangement is or contains a lease at inception. We have lease agreements with lease and non-lease components, and have elected to not separate these components for all classes of underlying assets.

Segment Reporting [Abstract]
Business Segments	Note 10 — Business Segments We have three segments: (i) Development and Redevelopment; (ii) Operating; and (iii) Other. Our Development and Redevelopment segment consists of properties that are under construction or have not achieved stabilization, as well as land held for development. Our Operating segment includes 21 residential apartment communities that have achieved stabilized level of operations as of January 1, 2021 and maintained it throughout the current year and comparable period. We aggregate all our apartment communities that have reached stabilization into our Operating segment. Our Other segment consists of properties that are not included in our Development and Redevelopment or Operating segments. During the nine months ended September 30, 2022 we disposed of two Seattle, Washington area properties that had previously been reported as held for sale assets and one stabilized property located in Fremont, CA that was previously reported within our Operating segment. In addition, we terminated the leases for four residential apartment communities that were previously reported within our Development and Redevelopment segment. Prior period segment information has been recast based upon our current segment population and is consistent with how our chief operating decision maker ("CODM") evaluates the business. The recast conforms with our reportable segment composition as of September 30, 2022. Our CODM uses cash flow, construction timeline to completion, and actual versus budgeted results to evaluate our properties in our Development and Redevelopment segment. Our CODM uses proportionate property net operating income to assess the operating performance of our Operating segment. Proportionate property net operating income is defined as our share of rental and other property revenues, excluding reimbursements, less direct property operating expenses, net of utility reimbursements, for consolidated communities. In our Condensed Consolidated Statements of Operations , utility reimbursements are included in Rental and other property revenues , in accordance with GAAP. As of September 30, 2022, our Development and Redevelopment segment consists of 10 properties: two residential apartment communities with 965 planned apartment homes, a single family rental community with 16 planned homes plus eight accessory dwelling units, and one hotel, with 106 planned rooms, we are actively developing or redeveloping; and, land parcels held for development. Our Operating segment includes 21 consolidated apartment communities with 5,582 apartment homes. Our Other segment includes Eldridge Townhomes apartment community, stabilized but not owned for the comparable reporting period, and 1001 Brickell Bay Drive, our only office building. The following tables present the results of operations of consolidated properties with our segments reported on a proportionate basis for the three months ended September 30, 2022 and 2021 (in thousands): Development and Redevelopment Operating Other Proportionate (1) Corporate and Amounts Not Allocated to Segments (2) Consolidated Three Months Ended September 30, 2022: Rental and other property revenues $ 123 $ 34,691 $ 4,241 $ 1,344 $ 7,284 $ 47,683 Property operating expenses 336 10,220 1,264 1,377 4,258 17,455 Other operating expenses not allocated (3) — — — — 96,247 96,247 Total operating expenses 336 10,220 1,264 1,377 100,505 113,702 Proportionate property net operating ( 213 ) 24,471 2,977 ( 33 ) ( 93,221 ) ( 66,019 ) Other items included in income before (4) — — — — 82,629 82,629 Income (loss) before income tax $ ( 213 ) $ 24,471 $ 2,977 $ ( 33 ) $ ( 10,592 ) $ 16,610 Development and Redevelopment Operating Other Proportionate (1) Corporate and Amounts Not Allocated to Segments (2) Consolidated Three Months Ended September 30, 2021: Rental and other property revenues $ 256 $ 31,126 $ 3,459 $ 1,300 $ 6,752 $ 42,893 Property operating expenses 472 10,301 1,124 1,293 4,965 18,155 Other operating expenses not allocated (3) — — — — 30,577 30,577 Total operating expenses 472 10,301 1,124 1,293 35,542 48,732 Proportionate property net operating ( 216 ) 20,825 2,335 7 ( 28,790 ) ( 5,839 ) Other items included in income before (4) — — — — ( 1,028 ) ( 1,028 ) Income (loss) before income tax $ ( 216 ) $ 20,825 $ 2,335 $ 7 $ ( 29,818 ) $ ( 6,867 ) The following tables present the results of operations of consolidated properties with our segments reported on a proportionate basis for the nine months ended September 30, 2022 and 2021 (in thousands): Development and Redevelopment Operating Other Proportionate (1) Corporate and Amounts Not Allocated to Segments (2) Consolidated Nine Months Ended September 30, 2022: Rental and other property revenues $ 204 $ 100,052 $ 13,619 $ 4,466 $ 30,034 $ 148,375 Property operating expenses 908 30,916 4,085 4,455 16,020 56,384 Other operating expenses not allocated (3) — — — — 172,663 172,663 Total operating expenses 908 30,916 4,085 4,455 188,683 229,047 Proportionate property net operating ( 704 ) 69,136 9,534 11 ( 158,649 ) ( 80,672 ) Other items included in income before (4) — — — — 402,506 402,506 Income (loss) before income tax $ ( 704 ) $ 69,136 $ 9,534 $ 11 $ 243,857 $ 321,834 Development and Redevelopment Operating Other Proportionate and Other Adjustments (1) Corporate and Amounts Not Allocated to Segments (2) Consolidated Nine Months Ended September 30, 2021: Rental and other property revenues $ 2,006 $ 90,176 $ 9,783 $ 3,863 $ 17,287 $ 123,115 Property operating expenses 1,737 30,461 3,251 3,825 12,226 51,500 Other operating expenses not allocated (3) — — — — 85,627 85,627 Total operating expenses 1,737 30,461 3,251 3,825 97,853 137,127 Proportionate property net operating 269 59,715 6,532 38 ( 80,566 ) ( 14,012 ) Other items included in income before (4) — — — — 333 333 Income (loss) before income tax $ 269 $ 59,715 $ 6,532 $ 38 $ ( 80,233 ) $ ( 13,679 ) (1) Represents adjustments for redeemable noncontrolling interests in consolidated real estate partnerships' share of the results of consolidated communities in our segments, which are included in the related consolidated amounts, but excluded from proportionate property net operating income for our segment evaluation.

We added a new Corporate segment to this table for presentation purposes to display these assets and the associated debt as of December 31, 2021. In addition to the amounts disclosed in the tables above, as of September 30, 2022 the Development and Redevelopment segment right-of-use lease assets and lease liabilities aggregated to $ 95.5 million and $ 98.5 million, respectively, and as of December 31, 2021, aggregated to $ 429.8 million and $ 435.1 million, respectively. As of September 30, 2022, right-of-use lease assets and lease liabilities primarily relate to our investments in Upton Place and Oak Shore. As described in Note 9, we entered into termination agreements to cancel our leases on North Tower of Flamingo Point, 707 Leahy, The Fremont, and Prism on September 1, 2022. Consequently, during the period ended September 30, 2022 , we wrote off $ 326.1 million and $ 337.3 million right-of-use lease assets and lease liability, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. ("GAAP") have been condensed or omitted in accordance with such rules and regulations, although management believes the disclosures are adequate to prevent the information presented from being misleading. In the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The Condensed Consolidated Balance Sheets of Aimco and Aimco Operating Partnership as of December 31, 2021 have been derived from their respective audited financial statements at that date, but do not include all of the information and disclosures required by GAAP for complete financial statements. For further information, refer to the financial statements and notes thereto included in Aimco’s and Aimco Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2021 . Except where indicated, the footnotes refer to both Aimco and Aimco Operating Partnership.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Aimco, Aimco Operating Partnership, and their consolidated subsidiaries. Aimco Operating Partnership’s condensed consolidated financial statements include the accounts of Aimco Operating Partnership and its consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. We consolidate a variable interest entity (“VIE”) in which we are considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. As used herein, and except where the context otherwise requires, “partnership” refers to a limited partnership or a limited liability company and “partner” refers to a partner in a limited partnership or a member of a limited liability company. Certain reclassifications have been made to prior period amounts to conform to the current period condensed consolidated financial statement presentation with no effect on the Company’s previously reported results of operations, financial position, or cash flows.
Common Noncontrolling Interests in Aimco Operating Partnership	Common Noncontrolling Interests in Aimco Operating Partnership Common noncontrolling interests in Aimco Operating Partnership consist of common Aimco Operating Partnership Units (“OP Units”), and are reflected in Aimco’s accompanying Condensed Consolidated Balance Sheets as Common Noncontrolling Interests in Aimco Operating Partnership . Aimco Operating Partnership’s income or loss is allocated to the holders of common OP Units, other than Aimco, based on the weighted-average number of common OP Units (including Aimco) outstanding during the period. For all periods presented, the holders of common OP Units had a weighted-average economic ownership interest in Aimco Operating Partnership of approximately 5.0 % . Substantially all of the assets and liabilities of Aimco are held by Aimco Operating Partnership. Redeemable Noncontrolling Interests in Consolidated Real Estate Partnerships Redeemable noncontrolling interests consist of equity interests held by a limited partner in a consolidated real estate partnership that has a finite life. If a consolidated real estate partnership includes redemption rights that are not within our control, the noncontrolling interest is included as temporary equity. The assets of these consolidated real estate partnerships must first be used to settle the liabilities of the consolidated real estate partnerships. The consolidated real estate partnerships' creditors do not have recourse to the general credit of Aimco Operating Partnership. In July 2022, we closed a $ 102.0 million preferred equity financing with an institutional investor, providing for a fixed 8 % annual rate of return payable monthly. In February 2022, we acquired all of the outstanding redeemable noncontrolling interests in two consolidated properties for $ 5.1 million. At the time of redemption, the carrying amount of the redeemable non-controlling interests was $ 4.9 million. Redeemable noncontrolling interests in consolidated real estate partnerships as of September 30, 2022 consists of the $ 102.0 million preferred equity noted above and our partner's equity interest in the Upton Joint Venture, which provides for an accruing 9.7 % rate of return on their investment. These investment interests are presented as Redeemable noncontrolling interests in consolidated real estate partnerships in our Condensed Consolidated Balance Sheet as of September 30, 2022. The following table shows changes in our redeemable noncontrolling interests in consolidated real estate partnerships from December 31, 2021 to September 30, 2022 (in thousands): Balance at December 31, 2021 $ 33,794 Capital contributions 124,723 Distributions ( 917 ) Redemptions ( 4,911 ) Net income 5,446 Balance at September 30, 2022 $ 158,135
Mezzanine Investment	Mezzanine Investment In November 2019, Aimco Predecessor made a five-year , $ 275.0 million mezzanine loan to the partnership owning the “Parkmerced Apartments” located in southwest San Francisco (the “Mezzanine Investment”). The loan bears interest at a 10 % annual rate, accruing if not paid from property operations. Ownership of the subsidiaries that originated and hold the mezzanine loan was retained by AIR following the Separation. The Separation Agreement provides for AIR to transfer ownership of the subsidiaries that originated and hold the mezzanine loan, a related equity option to acquire a 30 % interest in the partnership owning Parkmerced Apartments and the interest rate option, or swaption, that provides partial protection against future refinancing risk to Aimco through 2024 once required third-party consents are received . At the time of the Separation and as of the date of this filing, legal title of these subsidiaries had not yet transferred to Aimco. Until legal title of the subsidiaries is transferred, AIR is obligated to pass payments received on such loan to us, and we are obligated to indemnify AIR against any costs and expenses related thereto. We have the risks and rewards of ownership of the Mezzanine Investment and have recognized an asset related to our right to receive the Mezzanine Investment from AIR. We recognize as income the net amounts recognized by AIR on its equity investment that are due to be paid to us when collected to the extent the income is supported by the change in AIR's claim to the net assets of the underlying borrower. The income recognized primarily represents the interest accrued under the terms of the underlying mezzanine loan. The loan and the underlying real estate are subject to certain risks, including, but not limited to, those resulting from the lingering disruption due to the COVID-19 pandemic and associated response, and any similar events that might occur in the future, which may result in all or a portion of the loan not being repaid. In the event we conclude that a portion of the Mezzanine Investment is not recoverable, we will recognize an impairment .
Income Tax Benefit (Expense)	Income Tax Benefit (Expense) Certain aspects of our operations, including our development and redevelopment activities, are conducted through taxable REIT subsidiaries, or TRS entities. Additionally, our TRS entities hold investments in one of our apartment communities and 1001 Brickell Bay Drive. Our income tax benefit calculated in accordance with GAAP includes income taxes associated with the income or loss of our TRS entities. Income taxes, as well as changes in valuation allowance and incremental deferred tax items in conjunction with intercompany asset transfers and internal restructurings (if applicable), are included in Income tax benefit (expense) in our Condensed Consolidated Statements of Operations . Consolidated GAAP income or loss subject to tax consists of pretax income or loss of our taxable entities and gains retained by the REIT. For the three and nine months ended September 30, 2022 , we had consolidated net loss and income subject to tax of $ 75.6 million and $ 91.0 million, respectively. For the three and nine months ended September 30, 2021 , we had consolidated net losses subject to tax of $ 7.9 million and $ 26.4 million, respectively. For the three months ended September 30, 2022, we recognized income tax benefit of $ 17.6 million compared to a $ 2.0 million benefit during the same period in 2021. The change is primarily due to the GAAP income taxes associated with the lease modification depreciation expense recognized in the third quarter of 2022. For the nine months ended September 30, 2022, we recognized income tax expense of $ 24.3 million compared to a $ 9.9 million benefit during the same period in 2021 . The change is primarily due to the GAAP income taxes associated with the net lease modification income recognized in 2022.
Use of Estimates	Use of Estimates The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts included in the financial statements and accompanying notes thereto. Actual results could differ from those estimates.
Cash Equivalents	Cash Equivalents We classify highly liquid investments with an original maturity of three months or less as cash equivalents. We maintain cash equivalents in financial institutions in excess of insured limits. We have not experienced any losses in these accounts in the past and believe that we are not exposed to significant credit risk because our accounts are deposited with major financial institutions.
Restricted Cash	Restricted Cash Restricted cash consists of tenant security deposits, capital replacement reserves, insurance reserves, and cash restricted as required by our debt agreements.
Other Assets, net	Other Assets, net Other assets were comprised of the following amounts (in thousands): September 30, 2022 December 31, 2021 Other investments $ 63,594 $ 45,386 Notes receivable 38,759 38,029 Unconsolidated real estate partnerships 28,958 13,025 Assets held for sale (1) 11,735 — Deferred costs, deposits, and other 11,667 22,136 Prepaid expenses and real estate taxes 10,489 20,516 Corporate fixed assets 8,484 9,855 Accounts receivable, net of allowances of $ 1,406 and $ 1,285 as of September 30, 2022 and December 31, 2021, respectively 2,544 2,469 Deferred tax assets 1,999 6,388 Intangible assets, net 1,176 3,269 Due from affiliates 1,236 4,840 Total other assets, net $ 180,641 $ 165,913 (1) In addition to the properties we sold during the period, from time to time we may market to sell certain properties that are inconsistent with our long-term investment strategy. At the end of each reporting period, we evaluate whether such properties meet the criteria to be classified as held for sale. As of September 30, 2022 , assets held for sale include one land parcel in Fort Lauderdale, Florida, which is expected to be sold during the fourth quarter of 2022.
Accounting Pronouncements Adopted in the Current Year	Accounting Pronouncements Adopted in the Current Year During the quarter ended March 31, 2022, we adopted ASU 2021-05 establishing Topic 842, Lessors - Certain Leases with Variable Lease Payments . ASU 2021-05 requires a lessor to classify a lease with variable payments that do not depend on an index or rate as an operating lease if either a sales-type lease or direct finance lease classification would trigger a day-one loss. The adoption of this standard on January 1, 2022 , did not have a material impact on our condensed consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the FASB issued Accounting Standards Update No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the LIBOR or by another reference rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued Accounting Standards Update 2021-01 , “Reference Rate Reform (Topic 848): Scope” (“ASU 2021-01”), which clarified the scope and application of the original guidance. We plan to adopt ASU 2020-04 and ASU 2021-01 when LIBOR is discontinued. We are currently evaluating the potential impact of adopting this guidance, but do not expect it to have a material impact on our co nsolidated financial statements due to the fact that we hold one month LIBOR debt instruments, which are not expected to be discontinued in 2022.
Fair Value of Financial Instruments	On a recurring basis, we measure at fair value our interest rate options, which are presented in Other assets, net in our Condensed Consolidated Balance Sheets . Our interest rate options are classified within Level 2 of the GAAP fair value hierarchy, and we estimate their fair value using pricing models that rely on observable market information, including contractual terms, market prices, and interest rate yield curves. The fair value adjustment is included in earnings in Unrealized gains on interest rate options in our Condensed Consolidated Statements of Operations . Changes in fair value are reflected as a non-cash transaction in adjustments to arrive at cash flows from operations, and any upfront premium is reflected in Purchase of interest rate options in our Condensed Consolidated Statements of Cash Flows .
