3. BROOKLYN HEIGHTS $3,150,000
1 Pierrepont Street, #8A GMAP
Sure, $3 million+ is a pretty penny, but the sale price for this sprawling co-op seems low given the prestige of the building and its asking price. (We’ve got a call into Brown Harris, which brokered the sale, to find out whether there was behind-the-scenes action not reflected in the public records sale price, and we’ll update this if they get back to us.) The 10-room co-op’s been on the market since last year, and the initial ask was $6,250,000, which was later reduced to $5,500,000. The reader widget guess on it clocked in at $4,764,268. Closed on 9/21/09; deed recorded on 9/24/09.
