Most Expensive Home in US: $100M Mansion Sells

A Russian billionaire has bought what the Wall Street Journal calls the nation's most expensive single-family home. Investor Yuri Milner paid $100 million for the Silicon Valley estate in Los Altos Hills. It's 25,500 square feet, with both an indoor and outdoor pool, a ballroom, a tennis court, etc. But Milner has no plans to move from Moscow anytime soon, making it a quaint second home for him.

The sale highlights a split in the real estate market, notes the Journal: Year-over-year sales of homes in the mere-mortal range of $100,000 to $250,000 were down 8% in February, but sales of those worth more than $1 million were up 4%. "The crummy real estate market is not in the high end," says one agent. (More real estate stories.)
