Facebook investor buys $100M Silicon Valley home

LOS ALTOS HILLS, Calif. - A Russian billionaire investor has purchased a lavish, 25,500-square-foot mansion in Silicon Valley for $100 million, believed to be the most ever paid for a single-family home in the United States.

The Wall Street Journal reports that 49-year-old Yuri Milner, an investor in Facebook, Groupon and Zynga, has no immediate plans to move into the home.

Milner is the founder of Digital Sky Technologies, an investment firm he started in 2005.

The mansion purchased by Milner is a French-style chateau set on 18 acres in hills overlooking San Francisco Bay.

The estate has a ballroom, wine cellar, gym, spa and pools inside and outside.

The Journal says the sale price beats the previous high of $95 million in 2008 for an estate in Palm Beach, Fla.
