Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sold Price | Sold | Source | | --- | --- | --- | --- | --- | | 1DR (Apartment) | 2 | $1,150,000 | April 21, 2026 | City record · MLS | | 7D (Apartment) | 4 | $5,200,000 | October 23, 2024 | City record · MLS | | 5B (Apartment) | — | $6,000,000 | February 22, 2024 | City record | | 1D (Apartment) | 1 | $1,425,000 | November 30, 2023 | City record · MLS | | 7B (Apartment) | 2 | $3,650,000 | February 6, 2023 | City record · MLS | | 10A (Apartment) | 4 | $2,995,000 | October 12, 2022 | City record · MLS | | 4A (Apartment) | 3 | $4,000,000 | March 7, 2022 | City record · MLS | | 8B (Apartment) | 3 | $7,500,000 | November 4, 2021 | City record · MLS | | 6C (Apartment) | 4 | $4,200,000 | October 6, 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 The median closed price for comparable four-bedroom sales at 850 Park Avenue is $4,200,000, based on 3 sales between October 2021 and October 2024. This home is asking $5,450,000, $1,250,000 above that median. The middle half of those sales closed between $3,597,500 and $4,700,000. - **Median closed price**: $4,200,000 - **Middle half**: $3,597,500 – $4,700,000 - **Based on**: 3 four-bedroom sales at 850 Park Avenue - **Period**: October 2021 – October 2024 Square footage is recorded for only 0 of these 3 sales (0%), 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. Across the 3 of these sales with a published asking price, the median closed at 87.4% of what it originally asked. 100% of them closed below the original ask. ### How these sales were negotiated - **Sold vs original ask**: 87.4% of the original ask - **Closed below ask**: 100% of 3 sales Across the 3 of these sales with a published asking price, the median closed at 87.4% of what it originally asked. 100% of them closed below the original ask. Based on 3 four-bedroom sales at 850 Park Avenue, October 2021 – October 2024. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. ### Price trend Median sold price for co-op four-bedroom sales in Lenox Hill, 2017 to 2026. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth. | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $5,875,000 | 15 | | 2018 | $4,595,000 | 18 | | 2019 | $2,600,000 | 11 | | 2020 | $3,275,000 | 12 | | 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 | $4,900,000 | 13 | This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Lenox Hill instead. 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.
