There's a lot to like about Cary Tamarkin's LEED-certified condo at 456 West 19th Street. Some of this has to do with its looks -- even amid the stiff competition provided by other Chelsea condo listings -- even the star-studded constellation of new condo listings around the High Line -- 456 West 19th Street is a beauty. (Architecture critics agree with us there) That there's some green building intelligence behind that elegant facade helps matters, too. And of course the condos for sale at 456 West 19th Street are exceptionally luxurious, even by Chelsea standards -- every apartment at 456 West 19th is a duplex, and the quality of finishes and fixtures are surpassingly high. But while we at New Construction Manhattan love us some 456 West 19th Street, it turns out that we're not alone -- Curbed reports that the high-end Chelsea condominium is shaping up as one of the true sales success stories of the current Manhattan real estate market. As is common -- even with NYC condo prices on the rise -- most of the condominiums for sale at 456 West 19th Street wound up selling for slightly less than their asking prices.
