Hedge funder Steven Schonfeld is in contract to buy an oceanfront Palm Beach, Florida, estate that will close for just under $200 million, the New York Post reported.

When the deal goes through for Schonfeld, he will have the most expensive mansion in U.S. history.

Ironically, the current record is just down the road on South Ocean Boulevard, the estate of late Broadway producer Terry Allen Kramer sold for $105million.

Schonfeld, 60, already has a mansion in his portfolio: a $90million property in Old Westbury, New York that boasts a nine-hole golf course and his own personal chef.

His soon-to-be Florida 4.3 acre home at 1415 South Ocean Boulevard is just a half-mile south of President Trump’s private club, Mar-a-Lago.

The palatial ocean home is currently owned by philanthropist Sydell Miller, who co-founded Matrix Essentials, a hair and beauty line, with her late husband, Arnold.

The mansion has 10 bedrooms, nearly 35,000 square feet of under-air square feet, 350 feet of oceanfront and about 230 feet of water frontage on the Intracoastal Highway, The Real Deal reports.

Schonfeld was named 18th-highest-earning hedge fund manager this year, according to Forbes. He has three children, including a 14-year-old daughter with ex-model Sidra Saucedo.
