The apartments
40 condominium apartments are assessed on this block, and the typical one is 634 sq ft (59 m²). They run from 46 to 129 m².
The city values the typical one at $109,042. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
4 apartments on this tax block changed hands in the year the city last published, at a median of $693,000, from 610,950 to 860,000.
Recorded sale prices from the Department of Finance’s rolling file, covering the year to Aug 31, 2026. Transfers under $10,000 are left out: New York records deed transfers between relatives at a dollar, and those are not sales. No apartment number and no name is carried from either side.
