Mickey Rabina, a lesser-known New York developer, is constructing a 1,000-foot supertall at 520 Fifth Avenue, set to be the tallest in its vicinity. Known for resolving distressed projects, Rabina took over after the original developer passed away and revived the stalled project. The building, featuring offices and condos, is 60% sold with a target sellout of nearly $400 million. Rabina pivoted the design to include a private club and a classic facade. His strategy focuses on long-term ownership, keeping lower portions as rentals while selling condos on top to reduce his overall costs.
