Input: A plush penthouse in one of New York's most expensive buildings is headed to foreclosure, signaling new troubles for the high-end real-estate market. 
  
  
  
 The 6,200-square-foot, full-floor unit at One57 is scheduled to go to foreclosure auction next month, according to Bloomberg. 
  
 The apartment, known as Apartment 79, sold in 2014 for just under $51 million. The identity of the buyer is unknown because it was purchased through an anonymous limited liability corporation called One57 79 Inc. The LLC took out a loan from Luxembourg-based Banque Havilland in 2015. When the borrower defaulted, the bank forced a sale. 
  
  
  
 When it opened in 2014, One57 was the shining symbol of a new class of luxury super-towers in Manhattan. Rising to over 1,000 feet, apartments were selling for nearly $7,000 a square foot, largely to overseas buyers. Billionaire hedge funder Bill Ackman and other partners bought the biggest penthouse for just about $90 million. 
  
  
  
 Yet starting last year, an oversupply of luxury towers and a scarcity of overseas buyers have hurt the top of the market. New development sales fell 25 percent in the latest quarter and units at One57 are selling for discounts of more than 20 percent. 
  
  
  
 The $51 million apartment is scheduled to head to auction on July 19. Another apartment that sold for $21 million at One57 went to foreclosure auction earlier this month, but there's no word yet on the result. ||||| Billionaire’s Row is headed toward Skid Row now that a second luxury condo at 157 W. 57th St. is slated to be sold in a foreclosure auction. 
  
 The building, known as One 57, is home to the city’s only $100 million condo. It was the city’s tallest residential building for a short time until nearby 432 Park Ave. was completed. 
  
 The latest unit in the building to hit foreclosure is a full-floor penthouse bought for $50.9 million in 2014 by a mystery buyer who hid the purchase behind an LLC, One57 79 Inc., according to PropertyShark. 
  
 The foreclosure auction was first reported by Bloomberg. 
  
 It could be the city’s most expensive residential foreclosure ever. 
  
 The buyer took out a $35.3 million mortgage from a Luxembourg bank, Banque Havilland SA, in 2015 and never repaid the loan, so the bank is forcing a sale. 
  
 Last month, The Post reported that a 56th-floor unit at One57 was also slated for a foreclosure auction. 
  
 Around 30 residential properties in Manhattan have been scheduled to go to foreclosure auction for the first time during the first quarter of 2017, PropertyShark’s Nancy Jorisch told The Post. 
  
 One57, created by Extell Development’s Gary Barnett, was funded by a subsidiary of an Abu Dhabi company linked to a multibillion-dollar global money-laundering investigation, The Post revealed last year. |||||

Billionaire’s Row is having some major first world problems. According to CNBC, the owner of Apartment 79, a full-floor penthouse that spans more than 6,000 square feet and overlooks Central Park, has defaulted on the nearly $51 million home. The luxury apartment at One57 tower, located in a part of midtown nicknamed Billionaire’s Row, went into foreclosure and is up for auction in July. “It’s probably the most expensive foreclosure we’ve ever seen in luxury development,” Donna Olshan, president of Olshan Realty Inc., tells Bloomberg. The mystery owner purchased the apartment anonymously in 2014 for $50.9 million, later taking out a $35 million loan in 2015 from Luxembourg bank Banque Havilland that was scheduled to be paid within one year. When the deadline passed, the bank forced a sale. The owners of Apartment 79 aren’t the only ones having trouble keeping up with their multi-million dollar home payments. According to the New York Post, this is the second luxury apartment at One57 to default this month. The luxury high-rise still boasts the most expensive residential sale in Manhattan, a $100.5 million dollar condo. But experts believe the recent defaults may signal a downturn in the luxury real-estate world. Per CNBC, units are now selling for 20% cheaper than when One57 opened in 2014 as the high-end market saw new development sales dip 25% in the last quarter. A surplus of luxury properties combined with fewer overseas buyers are thought to be causing the downturn.
