Those are excluded from the benchmark below. ### How this price compares - **This home**: $5,500,000 - **Median sold price**: $4,250,000 - **Difference**: +$1,250,000 (+29.4%) - **Comparable sales**: 23 - **Sales from**: September 2024 – August 2026 - **Middle half of those sales**: $3,362,500 – $5,617,500 Based on co-op four-bedroom sales in Carnegie Hill. Square footage is recorded for only 6 of these 23 sales (26%), 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 Carnegie Hill instead. ### How these sales were negotiated - **Sale-to-list price**: 95.7% (22 sales) - **Sold below asking**: 73% (22 sales) - **Typical time to find a buyer**: 48 days (22 sales) - **Typical time to close**: 111 days (22 sales) Based on co-op four-bedroom sales in Carnegie Hill 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 four-bedroom sales in Carnegie Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $5,332,500 | 12 | | 2019 | $4,995,000 | 13 | | 2021 | $4,637,500 | 14 | | 2022 | $4,150,000 | 12 | | 2024 | $3,400,000 | 10 | | 2025 | $5,160,454 | 17 | Based on recorded co-op four-bedroom sales in Carnegie Hill. 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.
