Forbes Lists World's Most Expensive Homes

NEW YORK -- For a mere $138 million, you can own a cozy 103-room English country home, with a panic room, marble driveways and helipads -- a property that tops the 2007 Forbes annual list of the world's priciest homes for sale.

Updown Court in Windlesham, Surrey, has 23 hectares of gardens and woodlands, five pools, 22 marble bathrooms and more than 4,500 square meters of living space, according to the list posted on Forbes.com.

Oh, and a bowling alley, too.

Coming a close second is The Hala Ranch, which means welcome in Arabic, a 39-hectare property in Aspen, Colorado, owned by Prince Bandar bin Sultan bin Abdul Aziz, the former Saudi ambassador to the United States -- a job that must pay well, since the asking price is $135 million.

Who are the prospective buyers?

"These properties are marketed internationally. I suppose you would say to the wealth of the world," said Joshua Saslove, the president of Joshua & Co., the listing broker of The Hala Ranch. "We all know there's been large growth in the petroleum fuel industry, but there's been an enormous amount in money management, private equity, in real estate."

At these prices, buyers pay cash, he said. Where would opulence be without Donald Trump, whose Maison de L'Amitie in Palm Beach, Florida, is up for sale at an asking price of $125 million.

Trump bought the estate, previously owned by health care executive Abe Gosman, in 2004 for $41.25 million at a bankruptcy auction, Forbes.com said.
