Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sold Price | Sold | Source | | --- | --- | --- | --- | --- | | 5D (Apartment) | 1 | $407,500 | January 8, 2025 | 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 co-op studio sales in Lenox Hill is $435,000, based on 112 sales between September 2024 and June 2026. This home is asking $350,000, $85,000 below that median. The middle half of those sales closed between $388,750 and $489,250. - **Median closed price**: $435,000 - **Middle half**: $388,750 – $489,250 - **Based on**: 112 co-op studio sales in Lenox Hill - **Period**: September 2024 – June 2026 Square footage is recorded for only 26 of these 112 sales (23%), 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 104 of these sales with a published asking price, the median closed at 96% of what it originally asked. 78% of them closed below the original ask. 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 - **Sold vs original ask**: 96% of the original ask - **Closed below ask**: 78% of 104 sales - **Listed → in contract**: 71 days (about 10 weeks) - **In contract → closed**: 90 days (about 13 weeks) Across the 104 of these sales with a published asking price, the median closed at 96% of what it originally asked. 78% of them closed below the original ask. Half of these homes were in contract within 71 days (about 10 weeks) of coming to market, based on the 106 with a recorded listing date. Once a deal was agreed, closing took a further 90 days (about 13 weeks), based on the 106 with both dates recorded. A co-op board package and its interview account for much of that. 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. Based on 112 co-op studio sales in Lenox Hill, September 2024 – June 2026. 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 studio sales in Lenox Hill, 2016 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 | | --- | --- | --- | | 2016 | $434,250 | 20 | | 2017 | $458,500 | 78 | | 2018 | $448,000 | 66 | | 2019 | $427,500 | 50 | | 2020 | $416,000 | 40 | | 2021 | $415,000 | 103 | | 2022 | $425,000 | 108 | | 2023 | $437,750 | 76 | | 2024 | $402,500 | 70 | | 2025 | $440,000 | 67 | | 2026 | $437,000 | 25 | 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.
