Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable three-bedroom sales at 829 PARK Avenue is $3,025,000, based on 7 sales between September 2022 and April 2026. This home is asking $2,950,000, $75,000 below that median. The middle half of those sales closed between $2,731,250 and $3,625,000. - **Median closed price**: $3,025,000 - **Middle half**: $2,731,250 – $3,625,000 - **Based on**: 7 three-bedroom sales at 829 PARK Avenue - **Period**: September 2022 – April 2026 Square footage is recorded for only 0 of these 7 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 7 of these sales with a published asking price, the median closed at 93.8% of what it originally asked. 71% of them closed below the original ask. ### How these sales were negotiated - **Sold vs original ask**: 93.8% of the original ask - **Closed below ask**: 71% of 7 sales - **Listed → in contract**: 19 days - **In contract → closed**: 114 days (about 16 weeks) Across the 7 of these sales with a published asking price, the median closed at 93.8% of what it originally asked. 71% of them closed below the original ask. Half of these homes were in contract within 19 days of coming to market, based on the 5 with a recorded listing date. Once a deal was agreed, closing took a further 114 days (about 16 weeks), based on the 6 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 7 three-bedroom sales at 829 PARK Avenue, September 2022 – April 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 three-bedroom 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 | $2,295,000 | 13 | | 2017 | $2,500,000 | 59 | | 2018 | $2,572,500 | 54 | | 2019 | $2,282,119 | 80 | | 2020 | $2,167,500 | 38 | | 2021 | $2,202,500 | 96 | | 2022 | $2,475,000 | 108 | | 2023 | $2,250,000 | 90 | | 2024 | $2,460,000 | 72 | | 2025 | $2,550,000 | 90 | | 2026 | $2,711,500 | 54 | 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.
