The apartments
186 condominium apartments are assessed on this block, and the typical one is 1,728 sq ft (161 m²). They run from 42 to 271 m².
The city values the typical one at $489,575. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
18 apartments on this tax block changed hands in the year the city last published, at a median of $1,525,000, from 56,004 to 4,950,000.
Recorded sale prices from the Department of Finance’s rolling file, covering the year to Sep 30, 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.
