Chartwell Estate ($350 Million)

Introduced to the market for the jaw-dropping sum of $350 million, Chartwell is currently the most expensive property on the market in the United States. The 10.3-acre Bel Air estate boasts a 25,000-square-foot main residence built by architect Sumner Spaulding in 1933. Inspired by 18th-century, French neoclassical architecture, the chateau-style abode served as the Clampett family’s mansion in the 1960s hit television series The Beverly Hillbillies. In 1986, it was purchased by the late Univision chairman A. Jerrold Perenchio.

Built for entertaining, the residence features a wine cellar, salon, ballroom, and period-paneled dining room. Outside, there’s a tennis court, manicured gardens, covered parking for 40 cars, and a 75-foot swimming pool—or, as it was better known to anyone who watched The Beverly Hillbillies, the cement pond.

Despite its exorbitant asking price, Chartwell may not be the U.S.’s most expensive listing for long. Developer Nile Niami’s Bel Air residence will reportedly list for half a billion dollars.
