Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable co-op two-bedroom sales in Carnegie Hill is $1,697,500, based on 70 sales between September 2024 and July 2026. This home is asking $2,650,000, $952,500 above that median. The middle half of those sales closed between $1,196,250 and $2,270,000. - **Median closed price**: $1,697,500 - **Middle half**: $1,196,250 – $2,270,000 - **Based on**: 70 co-op two-bedroom sales in Carnegie Hill - **Period**: September 2024 – July 2026 Square footage is recorded for only 20 of these 70 sales (29%), 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 66 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 73% 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 Carnegie Hill instead. ### How these sales were negotiated - **Sold vs original ask**: 96.2% of the original ask - **Closed below ask**: 73% of 66 sales - **Listed → in contract**: 85 days (about 12 weeks) - **In contract → closed**: 104 days (about 15 weeks) Across the 66 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 73% of them closed below the original ask. Half of these homes were in contract within 85 days (about 12 weeks) of coming to market, based on the 67 with a recorded listing date. Once a deal was agreed, closing took a further 104 days (about 15 weeks), based on the 67 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 70 co-op two-bedroom sales in Carnegie Hill, September 2024 – July 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 two-bedroom sales in Carnegie 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 | $1,700,000 | 30 | | 2018 | $1,550,000 | 32 | | 2019 | $1,850,000 | 28 | | 2020 | $1,437,250 | 20 | | 2021 | $1,687,500 | 48 | | 2022 | $1,787,500 | 36 | | 2023 | $1,500,000 | 25 | | 2024 | $1,712,500 | 31 | | 2025 | $1,525,000 | 42 | | 2026 | $1,950,000 | 18 | 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 Carnegie 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.
