The 15 Central Park West flip parade has commenced! The first king-sized flip at the building has hit the market, and it could set a record for the most expensive apartment in New York. Last month venture capitalist Dr. Lindsay Rosenwald closed on a duplex at 15 CPW for $30 million; now, only a few weeks later, he's trying to flip it for three times that. The unit, 18/19A, features four bedrooms, six and a half baths, and a media room. What else will $90 million get you? A breath of fresh air: the apartment features 1,110 square feet of outdoor terraces.
