HIGHLIGHT $870M The price of the XI, HFZ’s most high-profile project currently in litigation In 2009, when the world’s financial system had been shaken to its core and New York’s once-sturdy real estate market was turned on its head, Ziel Feldman was floating on top of it all. In the downbeat days of the Great Recession, Feldman’s HFZ Capital Group reveled in the crisis. “When the market crashed, I started seeing opportunity,” Feldman told Crain’s in 2013. At that point Feldman and The Related Cos. recently had finished turning around One Madison Park, one of the real estate bubble’s most infamous flops. He had plans to sell about 1,000 luxury condos across Manhattan in the ensuing few years. His company was still two years away from what remains its most famous purchase: a site by the High Line at 76 11th Ave. The XI, as the luxury condominium is now called, cost the company a staggering $870 million in 2015.
