This is the most expensive house in the United States. Listed for $250 million USD, the sprawling mansion looks more like a full-fledged cruise ship than it does a home. Located in Bel-Air, the home comes equipped with seven staff members, a helicopter and multiple recreation rooms. It features stunning swimming pools, a bowling alley, theater and an impressive art collection. Most shocking though is the home’s expansive car collection with 12 vehicles and 10 motorcycles. From a Rolls-Royce Dawn, Ferrari 488, Pagani Huayra and more, the home is definitely for the ultimate 1 percenter. Check out the full listing here.
