Cohen, meanwhile, expanded his real estate investments beyond Trump properties. Learning skills from the boss, he invested in New York City real estate and made substantial profits. Starting in 2011, he bought four New York City buildings and sold them for $32 million. One property, a modest apartment building at 172 Rivington St., cost him $2 million in 2011. Three years later, he sold it for $10 million to a family real estate fund represented by Brooklyn lawyer Herbert Chaves, who did not respond to a request for comment. Cohen used the proceeds in 2015 to purchase an interest in a $58 million, seven-story apartment building on the Upper East Side.
