Reading these records

The transaction history above comes from ACRIS, the city's register of recorded deeds - it shows what actually closed, not what was asked. To compare that against what similar units are listed at, see how to find comps and asking price vs sale price. The BBL identifying this lot is explained in what is a BBL.
