It made sense at first, all those visitors to New Construction Manhattan clicking on the listing for Upper West Side condominium The Apthorp. It made sense because The Apthorp has always been among our most popular Upper West Side condo listings -- it's generally one of the most-clicked buildings in our Manhattan condo listings database, in fact -- and because it's a beautiful building filled with beautiful apartments for sale. Business as usual, right? Except they kept clicking. And clicking. The reason, we quickly figured out, was this story from the New York Post, which detailed what seemed like an incredible deal -- a (small) penthouse apartment at The Apthorp selling for $228,000, which is roughly 88% below its listing price. We'd click, too, if we read a story about apartments for sale in one of the hottest pre-war condominiums on the Upper West Side. So, how incredible was this deal?
