Bill Gates Medina, Wash. Net Worth: $50 billion Rank: 1 Bill Gates has gone underground. The high-tech billionaire's home is built into a hillside on the edge of Lake Washington, near Seattle. The 66,000-square-foot compound includes a 60-foot swimming pool with an underwater music system, a domed library with two "secret" bookcase doors and a 1,000-square-foot dining room. The family quarters, however, are said to be modest. The five-acre estate comes with a whopping tax bill--nearly $1 million in 2005, according to The Seattle Times.

Warren Buffet
Omaha, Nebr. Net Worth: $42 billion Rank: 2 The Oracle of Omaha lives in mighty modest digs, given the size of his fortune. He still resides in the gray stucco home he bought in 1958 for $31,500. Totaling about 6,000 square feet, in 2003, the Happy Hollow house was assessed at just $700,000 (though the value investor thought it was really worth about $500,000). Buffett sold one of his two Laguna Beach, Calif., properties, but still has one valued at about $4 million. That's still less than one hundredth of a percent of his estimated net worth.

Lakshmi Mittal
London, England Net Worth: $23.5 billionRank: 5 The steel magnate set real estate records in 2004 when he paid $128 million for a townhouse in London's Kensington Palace Gardens. The posh neighborhood was once just that--the vegetable-growing grounds for the royal residence. Now, it's better known as Billionaires' Row. Mittal's mansion, tucked between Kensington Palace and the Sultan of Brunei's spread, has garage space for 20 cars and is embellished with marble taken from the same quarry as that for the Taj Mahal. Mittal has another home in London, and is said to have residences in Delhi, Indonesia and Trinidad.
Wahaha, Anyone thinking of getting a house like that? haha~ I love Bill Gate's one best (for obvious reasons)! OMG! Personal Library, with 2 secret doors... so like what we see in the movies!!! And underground music chamber... together with a personal jetty... what else can one ask for manz... But imagine paying taxes amounting up to $1M... omg! You really got to be a "bill gate" to live like that... yeah... maybe next time i shall just buy some ooloo island off phillipines or indonesia or sth... haha~ that would be cool... hahha~

And yes, that's Buffet's Car... 2001 Lincoln Town Car Signature Series.
With a license plate that reads “THRIFTY,” it could belong to no other than billionaire investor Warren Buffett. The car behind the license plate is also relatively thrifty: a 2001 Lincoln Town Car Signature Series. Despite his license plate, one can only wonder why the billionaire splurged on the Signature Series Lincoln Town Car with its stylish half-length vinyl top instead of saving a few thousand dollars on a Ford Crown Victoria. Regardless, Buffett prefers the Lincoln’s wide bench seats and will take an American Town Car over a Cadillac or Lexus any day.
Yeah... Rich people like that are not necessarily stout. haha~ You don't have to drive a benz or a ferrari to show that you are rich... just own an island will do... hahahhaa~
