Last night we noted that yet another luxury condo at Manhattan’s One57 tower, a member of “Billionaire’s Row,” a group of high-end towers clustered along the southern edge of Central Park, had gone into foreclosure – the second in the span of a month. The 6,240-square-foot, full-floor penthouse in question, One57’s Apartment 79, sold for $50.9 million in December 2014, making it the eighth-priciest in the building and likely the largest residential foreclosure in Manhattan’s history.
