Subsequent Events	Note 10 — Subsequent Events Subsequent to quarter end, in October 2025, we completed the transfer of ownership interests with our joint venture partner at the development land sites along Broward Avenue in Fort Lauderdale, Florida. We exchanged our ownership in 200 Broward Avenue, which was subject to a non-performing seller financing note with a carrying value of $19.0 million presented within Notes Receivable in our Condensed Consolidated Balance Sheets as of September 30, 2025, along with $7.5 million of cash, for full ownership of 300 Broward Avenue. Subsequent to quarter end, we amended the December 30, 2024 agreement to sell the properties located at 1001 Brickell Bay Drive and 1111 Brickell Bay Drive in Miami, Florida (together referred to as the “Brickell Assemblage”) to Brickell Bay Property Owner LLC (the “Buyer”) for a gross price of $520.0 million.

On November 8, 2025, the agreement was amended such that closing is now scheduled for December of 2025 and the buyer will finance $70.0 million of the purchase price with transferable seller financing notes from Aimco. The seller financing notes will have a term of 24 months with a compounding interest rate that increases from 12% to 22% over the duration of the loan as well as exit fees ranging from 1% to 4%. In addition, on November 10, 2025, $15.0 million of the $50.0 million non-refundable deposit has been released to Aimco with the remainder held in escrow, $20.0 million is to be released to Aimco on the original closing date, November 18, 2025, and $15.0 million will be applied to the closing. Subsequent to quarter end, on November 10, 2025, our Board of Directors (the “Board”) determined advisable and approved a Plan of Sale and Liquidation (the “Plan of Sale and Liquidation”). The Plan of Sale and Liquidation provides for the Company’s complete liquidation and dissolution in accordance with Section 331, Section 336 and Section 346(a) of the Internal Revenue Code of 1986 (the “Code”), as amended, and the Maryland General Corporation Law. Effectiveness of the Plan of Sale and Liquidation is subject to approval by the affirmative vote of the holders of Common Stock entitled to cast two-thirds of all the votes entitled to be cast on the matter. Aimco currently anticipates that the Plan of Sale and Liquidation would be submitted for stockholder approval at a special meeting of stockholders, expected to occur in early 2026.
