The apartments
496 condominium apartments are assessed on this block, and the typical one is 1,558 sq ft (145 m²). They run from 41 to 985 m².
The city values the typical one at $647,968. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
77 apartments on this tax block changed hands in the year the city last published, at a median of $77,002,366, from 612,500 to 77,002,366.
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.

What is recorded here
Multiple filings, one stable building identifier.
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work.

The matched set includes 4 alteration filing. Its latest status categories are 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
