Public record marks a price taken from the deed filed with the City of New York. Rows without it show the price reported to the listing service, which is what is available until the deed is recorded, typically about two weeks after closing.

The percentage beside a closing price is the sale measured against the original asking price. Rows with no asking price are sales with no listing behind them. Those are sponsor and off-market transfers taken from the public record.

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. 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.

Where an abatement applies, Property Tax is the amount owed after it. Abatements are granted to the property and do not necessarily transfer to a new owner.

Figures are the New York City Department of Finance assessment roll for tax lot 1009270015. 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.

### Gramercy Park

Gramercy Park is famous for the only private park in Manhattan. It is quiet, leafy, and incredibly exclusive. Historic townhouses and pre-war co-ops. Access to the park (a key) is tied to specific buildings. Old New York elegance. Quiet, refined, and private. Irving Place offers polite dining. 6 train at 23rd. L train at 3rd Ave. A bit of a walk to the west side lines. The Park (if you have a key). Stuyvesant Square is the public alternative. Excellent dining. Best for those seeking privacy, history, and the ultimate status symbol (a key).
