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.

65 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.

The building on the lot

Section through the lot

PERMITTED, NOT BUILTLOT 9,000 SQ FT6
Drawn from PLUTO: 6 storeys, 43,032 sq ft of building on 9,000 sq ft of lot, an average floor plate covering 80% of it. The dashed outline is the difference between the floor area ratio already built (4.78) and the residential floor area ratio of the zoning district (6.02). It is a diagram of recorded figures, not a picture of the building.

Assessment

Assessed per residential unit

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.
