Square footage is recorded for only 3 of these 7 sales (43%), 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. ### How these sales were negotiated - **Sale-to-list price**: 80.1% (5 sales) - **Sold below asking**: 80% (5 sales) - **Typical time to find a buyer**: 183 days (6 sales) - **Typical time to close**: 112 days (6 sales) Based on two-bedroom sales at 870 Fifth Avenue 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 two-bedroom sales in Lenox Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2016 | $1,400,000 | 25 | | 2017 | $1,440,000 | 135 | | 2018 | $1,427,500 | 126 | | 2019 | $1,400,000 | 105 | | 2020 | $1,302,500 | 76 | | 2021 | $1,300,000 | 245 | | 2022 | $1,350,000 | 207 | | 2023 | $1,390,000 | 151 | | 2024 | $1,350,000 | 163 | | 2025 | $1,400,000 | 181 | | 2026 YTD | $1,462,500 | 90 | Based on recorded co-op two-bedroom sales in Lenox Hill. 2026 is year-to-date.
