Curbed New York has a nice article about the sale with some remarkable photos of the inside of the house (below). In one you can see that part of Houdini's original bookcase still stands in what I believe is the second floor parlor. The house itself has been converted into a three-family home, with an owner’s duplex occupying the first two floors, a one-bedroom apartment on the second floor, and a two-bedroom on the third floor. The house still contains the original wood in the foyer and tin ceilings.
Houdini purchased "278" (as he called it) in 1904 for $25,000. Bess sold the house in June 1927 to her neighbors, John and Fillippina Bonanno, whose daughters lived in the house until the late 1970s. This is the first time the house has been on the market in 26 years (interesting number). The last time it sold was in 1991 to Fred Thomas. When Thomas bought the house he was not told it was the former home of Houdini. But today's listing at Douglas Elliman proudly uses it as a selling point.
Check out the article about the sale at Curbed New York (who nicely linked to WAH). You can view the listing and all the photos at Douglas Elliman Real Estate. Agents are Beverley Draggon and Detria Davu.
Thanks to everyone who altered me to this this morning.
