This home is asking $17,700,000, $11,800,000 above that median. The middle half of those sales closed between $5,295,500 and $9,950,000. - **Median closed price**: $5,900,000 - **Middle half**: $5,295,500 – $9,950,000 - **Based on**: 15 house sales in Chelsea - **Period**: November 2021 – September 2026 - **Median $/ft²**: $1,436/ft² Across the 11 of these sales with a published asking price, the median closed at 90.8% of what it originally asked. 100% of them closed below the original ask. A house is not part of a building of comparable apartments, so this benchmark is drawn from house sales across Chelsea. Apartment sales are excluded from it entirely. ### How these sales were negotiated - **Sold vs original ask**: 90.8% of the original ask - **Closed below ask**: 100% of 11 sales - **Listed → in contract**: 175 days (about 25 weeks) - **In contract → closed**: 70 days (about 10 weeks) Across the 11 of these sales with a published asking price, the median closed at 90.8% of what it originally asked. 100% of them closed below the original ask. Half of these homes were in contract within 175 days (about 25 weeks) of coming to market, based on the 15 with a recorded listing date. Once a deal was agreed, closing took a further 70 days (about 10 weeks), based on the 15 with both dates recorded. 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 15 house sales in Chelsea, November 2021 – September 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. 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.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 1007460064. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
