The apartments
140 condominium apartments are assessed on this block, and the typical one is 3,287 sq ft (305 m²). They run from 91 to 608 m².
The city values the typical one at $1,256,904. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
23 apartments on this tax block changed hands in the year the city last published, at a median of $2,337,500, from 395,000 to 16,250,000.
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.

Read from the brokerages’ own published listings on September 22, 2026. A home drops off this table the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn. What we know is that it is no longer offered, which is why this shows what they have today rather than what we were told once. Everything on the market across the city.

What is recorded here
Multiple filings, one stable building identifier.

The matched set includes 2 alteration filing. Its latest status categories are 1 recorded as completed, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
