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.

## Potential NYC Second-Home Tax

This property may be subject to New York City’s non-primary residence surcharge if it is not used as a qualifying primary residence. The surcharge is based on the NYC Department of Finance market value, not the listing price.
