Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | 9A (Apartment) | 2 | — | $2,900,000 | — | July 1, 2025 | City record · MLS | | 13D (Apartment) | 3 | 2,200 | $1,500,000 | $682/ft² | June 24, 2024 | City record · MLS | | 105 (Apartment) | 1 | — | $500,000 | — | February 23, 2023 | City record · MLS | | 4/5B (Duplex) | 3 | — | $4,975,000 | — | January 27, 2023 | MLS | | 6/7B (Apartment) | 3 | — | $4,700,000 | — | July 6, 2022 | MLS | | 5C (Apartment) | 5 | — | $5,405,000 | — | October 21, 2021 | City record · MLS | Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares - **This home**: $5,500,000 - **Median sold price**: $2,373,750 - **Difference**: +$3,126,250 (+131.7%) - **Comparable sales**: 88 - **Sales from**: October 2024 – August 2026 - **Middle half of those sales**: $1,951,250 – $3,143,750 Based on co-op three-bedroom sales in Upper East Side. Square footage is recorded for only 19 of these 88 sales (22%), 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 Upper East Side instead. ### How these sales were negotiated - **Sale-to-list price**: 96.5% (77 sales) - **Sold below asking**: 70% (77 sales) - **Typical time to find a buyer**: 62 days (82 sales) - **Typical time to close**: 104 days (82 sales) Based on co-op three-bedroom sales in Upper East Side 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 Upper East Side | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $2,990,000 | 37 | | 2018 | $2,250,000 | 40 | | 2019 | $2,089,500 | 36 | | 2020 | $1,985,000 | 27 | | 2021 | $2,003,666 | 59 | | 2022 | $2,120,000 | 75 | | 2023 | $2,100,000 | 45 | | 2024 | $2,125,000 | 38 | | 2025 | $2,237,500 | 51 | | 2026 YTD | $2,597,500 | 32 | Based on recorded co-op three-bedroom sales in Upper East Side. 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.
