The apartments
18 condominium apartments are assessed on this block, and the typical one is 2,125 sq ft (197 m²). They run from 85 to 234 m².
The city values the typical one at $1,095,608. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
3 apartments on this tax block changed hands in the year the city last published, at a median of $1,875,000, from 1,800,000 to 2,830,000.
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.
