1192 Park Avenue

Real estate legend and "Shark Tank" star Barbara Corcoran bought a glamorous duplex penthouse on the Upper East Side back in April 2015. She and her husband, former FBI agent William Higgins, dropped $10 million on the pad, quite the steal considering it originally listed for $17 million. A year later, they listed their other home in the 'hood, a classic Rosario Candela-designed co-op at 1192 Park Avenue. Now, five months later, they've unloaded the home for $4.87 million (h/t NYP), just under the $4.9 million asking price and a good deal more than the $3.5 million they bought it for in 2000.
