South of Houston Street, buyers of luxury real estate have a host of great options: the lofts in landmark cast-iron SoHo buildings; brand new luxury apartments and converted office spaces in the Financial District; converted factories and warehouses in Tribeca, etc. The list goes on and on. These neighborhoods are the most popular neighborhoods in Manhattan, and the prices reflect that; SoHo and Tribeca are the most expensive places to live in the borough. One thing that you won’t often find downtown, however, is the “Classic Six,” the moniker for pre-war 2-bedrooms with a formal dining room, maid’s room, and 1 or 2 bathrooms. Long considered the height of luxury living in Manhattan, the Classic Six is struggling to maintain its status as the best that Manhattan has to offer. Judging by the prices, lofts are now equally as popular, because both sell for the same price range. Many factors have contributed to this shift, but the primary one is that Manhattan’s most popular neighborhoods simply don’t have any Classic Sixes to offer, and buyers don’t seem to have a problem with that.
