Square footage is recorded for only 14 of these 51 sales (27%), 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 Carnegie Hill instead. ### How these sales were negotiated - **Sale-to-list price**: 96.4% (48 sales) - **Sold below asking**: 65% (48 sales) - **Typical time to find a buyer**: 57 days (49 sales) - **Typical time to close**: 106 days (49 sales) Based on co-op three-bedroom sales in Carnegie 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 three-bedroom sales in Carnegie Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $3,580,000 | 19 | | 2018 | $3,450,000 | 29 | | 2019 | $3,137,500 | 22 | | 2020 | $2,760,000 | 18 | | 2021 | $2,497,500 | 36 | | 2022 | $2,400,000 | 29 | | 2023 | $2,760,000 | 33 | | 2024 | $2,625,000 | 29 | | 2025 | $2,561,250 | 26 | | 2026 YTD | $3,550,000 | 18 | Based on recorded co-op three-bedroom sales in Carnegie Hill. 2026 is year-to-date. Sales data through September 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.
