What it sold for
12 apartments on this tax block changed hands in the year the city last published, at a median of $2,500,000, from 850,000 to 6,450,000.
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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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.
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 2 under review, 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
