Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | 4-A (Apartment) | Studio | — | $302,000 | — | December 13, 2022 | City record · MLS | | 3A (Apartment) | Studio | — | $350,000 | — | November 8, 2022 | City record · MLS | | 5A (Apartment) | Studio | 400 | $325,000 | $813/ft² | July 15, 2022 | City record | 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 - **This home**: $549,000 - **Median sold price**: $682,817 - **Difference**: -$133,817 (-19.6%) - **This home, $/ft²**: $878 - **Comparable sales**: 36 - **Sales from**: November 2024 – July 2026 - **Middle half of those sales**: $613,750 – $896,250 Based on co-op one-bedroom sales in Carnegie Hill. Square footage is recorded for only 13 of these 36 sales (36%), 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**: 99.2% (33 sales) - **Sold below asking**: 52% (33 sales) - **Typical time to find a buyer**: 74 days (34 sales) - **Typical time to close**: 88 days (34 sales) Based on co-op one-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 one-bedroom sales in Carnegie Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $622,500 | 20 | | 2018 | $710,000 | 16 | | 2019 | $585,000 | 17 | | 2020 | $609,720 | 16 | | 2021 | $653,000 | 25 | | 2022 | $640,000 | 25 | | 2023 | $616,000 | 19 | | 2024 | $567,500 | 14 | | 2025 | $687,500 | 22 | | 2026 YTD | $690,634 | 13 | Based on recorded co-op one-bedroom sales in Carnegie Hill. 2026 is year-to-date. Sales data through July 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.
