What has sold here

Every transfer the City has recorded against this lot since 2003 with a consideration above zero. A co-op apartment has no deed, so its sale is recorded as a Real Property Transfer Tax return instead; both are printed here and the instrument is named in the last column. The figure is the consideration as filed, which is not always the price a buyer would recognise.

51 transfers are recorded against this building since 2003. The 40 most recent are printed here; the yearly summary above counts all of them.
RPTT&RET
BOTH RPTT AND RETT. A New York City Real Property Transfer Tax return filed together with the New York State return. A co-operative apartment sale conveys shares rather than real property, so this return, and not a deed, is what gets recorded.
RPTT
NYC REAL PROPERTY TRANSFER TAX. A New York City Real Property Transfer Tax return filed on its own.

The building on the lot

Section through the lot

PERMITTED, NOT BUILTLOT 12,100 SQ FT5
Drawn from PLUTO: 5 storeys, 37,887 sq ft of building on 12,100 sq ft of lot, an average floor plate covering 63% of it. PLUTO records 3 buildings on this lot, so the mass drawn is their combined floor area. The dashed outline is the difference between the floor area ratio already built (3.13) and the residential floor area ratio of the zoning district (4). It is a diagram of recorded figures, not a picture of the building.

Assessed value is the figure the Department of Finance uses to levy property tax. For a class two building it is derived from an income approach and it is capped in how fast it can rise. It is not a market valuation and the two figures routinely differ by a wide margin. What the assessment does and does not tell you.
