Price trend
Median price per square foot for sales at Polhemus, 2019 to 2025. Price per square foot is used rather than sale price so the line follows the market rather than whichever apartments happened to change hands that year.
| Year | Median $/ft² | Sales |
|---|---|---|
| 2019 | $1,652/ft² | 12 |
| 2022 | $1,732/ft² | 3Thin |
| 2025 | $1,696/ft² | 3Thin |
Years marked "thin" rest on fewer than 5 sales, where a single unusual apartment moves the median a long way. Read those points as the small samples they are rather than as the market turning.
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 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 3002951216. 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.
