Square footage is recorded for only 12 of these 40 sales (30%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Lenox Hill instead. ### How these sales were negotiated - **Sale-to-list price**: 99.2% (38 sales) - **Sold below asking**: 53% (38 sales) - **Typical time to find a buyer**: 63 days (40 sales) - **Typical time to close**: 95 days (40 sales) Based on co-op four-bedroom sales in Lenox Hill with the required listing and closing data. Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. ### Price trend Median sale price, co-op four-bedroom sales in Lenox Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $5,875,000 | 15 | | 2018 | $4,595,000 | 18 | | 2019 | $2,600,000 | 11 | | 2020 | $3,550,000 | 11 | | 2021 | $3,800,000 | 24 | | 2022 | $3,062,500 | 24 | | 2023 | $4,100,000 | 24 | | 2024 | $4,825,000 | 36 | | 2025 | $4,150,000 | 19 | | 2026 YTD | $4,900,000 | 17 | Based on recorded co-op four-bedroom sales in Lenox Hill. 2026 is year-to-date. Sales data through August 2026. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
