$100 Million Mansion: Most expensive home in U.S. has been bought

It's nice to know that in these hard economic times, the world's billionaires are doing alright. One billionaire in particular, Yuri Milner, recently decided to buy a new house: a sprawling $100 million California mansion - the most expensive one-family home ever sold in the U.S.

The 25,500-square-foot home in Los Altos home is modeled like a French chateau on steroids. It has five bedrooms, nine bathrooms and sits on 11 acres of land. There is also a ballroom and indoor and outdoor pools, according to the Wall Street Journal.

The 49-year-old Yuri Milner made his fortune in the digital world with Digital Sky Technologies. He rocketed to wealth with a $200 million investment in Facebook two years ago that has since turned into $10 billion.

Meanwhile, most housing prices across the country have been falling. Some major cities are experiencing the lowest prices in eleven years. Clearly, Milner knows a buyer's market when he sees one.

Milner, who lives in Moscow with his wife and two children, told the Wall Street Journal through a spokesman that he has no plans to move into the house he just dropped nine figures for. Good for him.
