Maryland Property Disposition [Line Items]
Purchase description		This sale resulted in net proceeds of approximately $58.7 million (inclusive of approximately $0.5 million in funds released from the Maryland Purchaser Escrow Payment for the three months ended January 31, 2024), after payment of related mortgage debt in the amount of $155.8 million and the corresponding swap breakage fees of approximately $213,000 related to the early termination of the interest rate swap contracts on the Damascus Property loan, payment of loans (including interest) to each of the equity owners in Grande Rotunda in the amount of approximately $31 million and certain transactional expenses and transfer taxes including brokerage fees due to Hekemian & Co. of approximately $6.4 million (see Note 8 for additional details). As of January 31, 2024, approximately $7,084,000 of the Maryland Purchaser Escrow Payment has been released from escrow to the Maryland Sellers. The escrow and related gain on sale were reduced by approximately $0.1 million and $0.2 million for the three months ended January 31, 2024 and 2023, respectively, due to a change in estimate related to a change in the timing of anticipated rent commencement dates for certain tenants, which will reduce the escrowed funds available to be released to Grande Rotunda. Approximately $0.3 million and $0.9 million of remaining funds are held in a post-closing escrow for rents and are included in “Funds held in post-closing escrow” on the accompanying condensed consolidated balance sheets as of January 31, 2024 and October 31, 2023, respectively. These funds held in post-closing escrow are anticipated to be released by the end of Fiscal 2025. The sale of the Maryland Properties resulted in a net gain of approximately $67.7 million (as adjusted) (with a consolidated impact to FREIT of approximately $45 million) which includes approximately $7.4 million of proceeds released and anticipated to be released from funds held in escrow, a write-off of the straight-line rent receivable of approximately $2.9 million and a write-off of unamortized lease commissions of approximately $1.7 million.
