This one may set a foreclosure record for New York as the owners have defaulted on a mortgage for their $50.9 million purchase of Apartment 79, which closed in 2015. The buyer's took a $35.3 million loan which was supposed to be repaid in full within 1 year. The full-floor penthouse unit spans 6,240 SF and was the 8th most expensive unit in the building at the time of sale.
