He and his wife bought the Highland Beach estate for $40 million the following year, records show. Built in 2013 on 1.4 acres, the mansion spans nearly 14,000 square feet, with eight bedrooms, 10 bathrooms, three half-bathrooms and a pool, records show. The estate includes a two-story library, wine room, gym, a theater, 150 feet of ocean frontage and two guest houses, according to the listing. 

Highland Beach is a small coastal enclave bounded by Boca Raton and Delray Beach. Prices have surged for oceanfront mansions in the town in recent years, fueled by increased demand for waterfront properties across South Florida. 

In March, the estate of late mattress mogul Harry Acker sold his oceanfront Highland Beach mansion for $21.2 million. Also in March, Gary Patrick, an advertising executive for Skechers, dropped $18.8 million on a waterfront townhome. In November, spec developer Pascal Nicolai sold an oceanfront mansion for $30 million.
