Only five units at One57 are on the market right now

Extell Development’s much-maligned billionaire’s tower One57 is nearly sold out.

Of the 157 West 57th Street building’s 94 apartments, only five were on the market as of Monday, according to marketing materials for the project. Two are three-bedroom residences between 3,000 and 4,200 square feet, one is a four-bedroom residence with 3,466 square feet, one is a five-bedroom with 5,475 square feet and one is a full-floor residence with 6,240 square feet. The prices of the remaining units range from $18.75 million for the smallest three-bedroom to $55.5 million for the full-floor unit.

Whether the leftovers are in the center of the building — reportedly the more difficult part of One57 to sell — is unclear. The units officially hit the market in December 2011, and by the following February, about 30 percent of the units were under contract, according to Extell founder Gary Barnett.

Among the known buyers at One57 are a Bill Ackman-led investor group that purchased the so-called Winter Garden penthouse for over $90 million and a set of Chinese parents who purchased a unit for their now toddler to use as a university student one day. — Julie Strickland
