Forbes 2010 List of America’s Most Expensive Homes

America's Top 5 Most Expensive Homes

1. $150 million
The Manor
Holmby Hills, Calif.
The home that Candy Spelling, widow of television giant Aaron, put on the market in 2008, out-prices every other property in the U.S. The 56,500 square-foot English-style mansion has a bowling alley, wine cellar, rooms for gift-wrapping and silver and china display, a library, gym and media room. Its 4.6 acres includes pools, a spa, landscaped gardens, a waterfall and parking for over 100 cars. Jeff Hyland from Hilton & Hyland Real Estate and Sally Forster Jones from Coldwell Banker Previews International have the listing.

2. $125 million
Fleur de Lys
Beverly Hills, Calif.
This 35,000-square-foot home, listed in 2007, is said to be modeled after Versailles, and the mansion makes no attempt at understatement. Its 12 bedrooms, 15 bathrooms, 50-seat screening room, Italian marble and gold-embossed leather walls ooze wealth. Owner Suzanne Saperstein hasn't compromised on the price in three years. After all, it's a relative bargain compared to the manor, just a few blocks away. The home is co-listed with Joyce Rey at Coldwell Banker Previews International and Robert Kass at Hilton & Hyland Christie’s Great Estates.

3. $100 million
Tranquility Estate
Lake Tahoe, Nev.
Tommy Hilfiger cofounder Joel Horowitz's 210-acre spread features the third-highest price tag in America. The 20,000-square-foot main house has extras like a cigar lounge, art studio and sports gym, while its grounds feature a golf course, boathouse and views of Lake Tahoe. A staircase in the home replicates the stairs of the S.S. Titanic. The home has been on the market for almost four years. Shari Chase at Chase International has the listing.

4. $80 million
Kaiser Estate
Honolulu, Hawaii
Separately, the three coastal parcels that comprise the former estate of industrialist Henry J. Kaiser wouldn't make this year's list, but together, the 5.5-acre property becomes one of the country's most expensive. The island getaway offers coastal views and a sleek mid-century style 15,000-square-foot home, extensively landscaped tropical grounds and a 12,000-square-foot boathouse and marina. Tech tycoon Fred Chan and his wife, Annie, put the home on the market in January 2009. Mary Worell of Sotheby's International Realty has the listing.

5. $75 million
Humming Bird Nest Ranch
Simi Valley, Calif.
Though it's named after the tiniest of birds, this property spans 123 acres. In addition to a 17,000-square-foot Spanish-Revival-style main house, six guest homes and 10 townhouses grace the estate, as does a fully equipped equestrian center and parking for 200 vehicles. If driving doesn't suit you, there's also a helicopter pad. On the market since late 2007, the home is co-listed with Drew Mandile and Brooke Knapp at Sotheby’s International Realty and Joyce Rey at Coldwell Banker Previews International.
