The 7 Most Expensive Real Estate in the World

6. Silicon Valley Chateau

Price: $100 million

In 2011, Russian billionaire Yuri Milner broke the record for a single-family home in the U.S. by purchasing this 25,000 square-foot, 18th century French-style chateau for $100 million. Although he apparently paid twice the value of the home, its opulence is nonetheless noteworthy. Indoor and outdoor pools, a ballroom, a 4,600 square-foot guest house, 14 bathrooms, and a private car wash are only some of this mansion’s features.
