The apartments
186 condominium apartments are assessed on this block, and the typical one is 906 sq ft (84 m²). They run from 23 to 207 m².
The city values the typical one at $390,140. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
8 apartments on this tax block changed hands in the year the city last published, at a median of $4,730,000, from 515,000 to 5,175,000.
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.

As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.
