Sheryl Sandberg owns a stately home right in the heart of the Bay Area with her husband David Goldberg, CEO of SurveyMonkey. The power couple hosted President Barack Obama at their Atherton house (above) for a $38,500 per person fundraiser in September 2011. Sandberg and Goldberg purchased the 12,470-square-foot home in 2004 for $7.995 million.
Thiel prefers to live outside of Silicon Valley in a home above the Sunset Strip. The property - coined the Chasen residence (above) - was originally built in 1950 by Hollywood designer Paul Revere Williams for restauranteur Dave Chasen. Like other billionaires, Thiel had the home completely customized, so the current property facts (4 bedrooms, 5 baths) may not tell the true story of the home's interior design. Reuters reports he owns 2.5 percent of Facebook.
It's safe to say that the second-richest man in the world - checking in at $61 billion - could live wherever he wants. But Seattle is home for the Microsoft founder, who has long lived in a custom family compound on Lake Washington in Medina, an enclave that looks directly across the lake to Seattle.

Ellison racks up an approximate $1.84 billion salary as the CEO and founder of Oracle. In addition to making sizable charitable donations, Ellison shows no shame in spending his self-made millions on personal items. His prized possessions include a private yacht, private jet, numerous exotic cars and a Woodside, CA estate, inspired by ancient Japanese architecture (pictured above.) Ellison's unique property spreads over 23 acres, includes a 7,800-sq ft main house, 9 other buildings and sits on a 2.3-acre, man-made lake. Before constructing the custom compound, Ellison sifted through a 5,000-square feet Manhattan penthouse, 8,000-sq ft Atherton mansion, and spent over $180,000,000 on 12 properties in Malibu. His most recent real estate investment includes a $10.5-million splurge in January 2010 on the historic Astor's Beechwood Mansion in Newport, RI. His Woodside home is his main residence.
