The apartments
26 condominium apartments are assessed on this block, and the typical one is 1,793 sq ft (167 m²). They run from 85 to 246 m².
The city values the typical one at $1,066,200. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
1 apartment on this tax block changed hands in the year the city last published, at a median of $4,450,000.
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.

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.
Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 1, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

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