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 - **Sale-to-list price**: 90.8% (11 sales) - **Sold below asking**: 100% (11 sales) - **Typical time to find a buyer**: 172 days (14 sales) - **Typical time to close**: 71 days (14 sales) Based on house sales in Chelsea 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. Sales data through September 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.

The City Council adopted FY2026/27 rates in June 2026, but they may still be revised under a later State law, and this table has not yet been updated with a final FY2026/27 rate. Every rate without the Estimated marker is the published rate for its year. 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. Assessed and billable values are from the New York City Department of Finance assessment roll for tax lot 1006950030. The City determines them for tax purposes; they are not an appraisal or an estimate of market value. Property tax is calculated from NYC Department of Finance assessment data, including recorded exemptions and abatements where applicable. Actual tax bills and a future buyer's taxes may differ. Tax classes and rates are set annually and can change.
