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.

| 118 transfers are recorded against this building since 2003. The 40 most recent are printed here; the yearly summary above counts all of them. | ||||
- DEED
- DEED. Conveys real property: a condominium apartment, or an entire building and the land under it.
- 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.

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.
