The Quick 10: The 10 Most Expensive Houses in the U.S.

I know some of you _flossers must be house-hunting out there "“ you've still got a couple of months to get in on that tax credit! So I'm passing on a list compiled by Forbes writer Matthew Woolsey - it's the 10 most expensive homes in the U.S. that are publicly for sale. That means a couple of the big ones (the Spelling Mansion, for instance) are out of play since they are privately listed. But I think you'll be pleased with the ones offered for public sale.

2. Tranquility, Lake Tahoe, Nevada. This one is owned by Joel Horowitz. You've probably never heard of him, but you know the brand he helped found: Tommy Hilfiger. It's 20,000 square feet and has a 3,500-bottle wine cellar, a 19-seat movie theater (how tiny) and, of course, an indoor swimming pool. It's on the market for a mere $100,000,000.

3. Unnamed, Bel Air, California. Maybe it belongs to Uncle Phil and Aunt Viv? There are 10 bedrooms and 14 bathrooms, so there's definitely room for Will, Hilary, Ashley, Carlton and Geoffrey. There's a 1,000-foot-long, 36-foot-high surrounding the property to keep Jazz out, and room for 20 cars in the garage. It's a steal for $85 million!

5. Hummingbird Nest Ranch, Simi Valley, California. This $75 million house is for the well-attended buyer: there are 10 "staff houses" on the property. And forget the 20-car garage "“ this Spanish-style ranch has a 37 stalls to keep your thoroughbred horses (they are thoroughbred, aren't they?). What's really nice is that you won't have to pay to have your own helipad installed "“ this house comes with.

6. Unnamed, Upper East Side, New York. For New York, this is enormous: 45 feet wide, six stories tall and 21,00 square feet of space. The space alone is probably worth the asking price of $75 million to some, but it also comes with a garden level, a library, a sauna, a home gym, six bedrooms, three staff rooms, a wine cellar and ten bathrooms. 10 bathrooms on six floors?! Does that seem a little unnecessary, or is that just me?

10. Unnamed, Upper East Side, New York. Ten thousand square feet, five bedrooms, eight bathrooms, a deck on the roof, a living room with 26-foot ceilings and a skylight conservatory "“ that's why this is going for $60 million. Haven't you always wanted to say you have a conservatory? "Hello, good to see you, we're just having some tea in the conservatory, it's such a nice day. Won't you join us?"

And, just for fun, the most expensive private residence ever built is due to be completed this year. Indian trillionaire Mukesh Ambani is having a billion-dollar house constructed that will include a six-floor garage to hold 168 cars, panic rooms, 600 servants and a 27-story mostly-glass tower with a helipad on top.

What mansion would you buy if you had the unlimited means to do so? I have to say, the Winchester Mystery House kind of speaks to me.
