Although we’re not quite in the heady days of last summer (yet), the Brooklyn townhouse market is still certifiably insane. For proof, look no further than the impressive-but-in-serious-need-of-renovation townhouse at 252 Carlton Avenue in Fort Greene, which was listed for $2.595 million, attracted 110 visitors and 22 offers in five days, and, a month later, went into contract for $3.2 million. According to its broker, it will need at least an additional $800,000 in repairs, including replacing the roof, floors, electrical, and plumbing. The 1864 house has undeniably great bones, though, and in this day and age that seems to be all that matters. As the sale has yet to close the identity of the buyers is still a mystery. [UPDATE: The sale has actually closed already.]
