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.

fleurdelys1. Fleur de Lys, Beverly Hills, California. If you've ever wanted to live in Louis XIV's palace at Versailles, you can "“ well, you can if you have $125 million you're willing to part with (don't we all?). It belonged to Suzanne Saperstein, the ex-wife of entrepreneur David Saperstein (he left her in 2006 to marry their nanny, in case you're interested). There's a 50-seat movie theater, a ballroom with frescoed ceilings, a nine-car garage and a library. Rumor has it that Mariah Carey recently made an offer on the mansion.

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!

dunnellen4. Dunnellen Hall, Greenwich, Connecticut. Ah, the economic times have done sad things to the Leona Helmsley's old house "“ it was selling for $125 million (the Helmsleys bought it in 1983 for just $9 million, including furniture) and is now listed at $75 million (scoop it up while you can! It's a buyer's market!). You not only get the 14 bedrooms, 13 bathrooms, vaulted ceilings, marble floors, limestone walls and a 52-foot-long swimming pool, you also get the 40 acres of land it sits on. And it kind of has a cool name. Let it be known that if I ever manage to acquire a mansion, it will be known as Toad Hall.

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?

bootjack7. BootJack Ranch, Pagosa Springs, Colorado. I think I could get behind this one. It has also had its price slashed, from $88 million to $68 million. While it only has four bedrooms and four bathrooms, it has a 12,000-foot spa and aquatic center. Yes, please!! It also includes 3,100 acres of land. Not bad, and check out that view "“ gorgeous.
8. Unnamed, Brentwood, California. Lots of amenities here "“ a tennis court, a pool, a sauna, and apparently a den all decked out like a casino, complete with craps table! There are also 17 bedrooms, 17 bathrooms and more than 22,000 square feet altogether.
9. Pickfair, Beverly Hills, California. If I had the money, I'd buy this one just for the history. And the ghosts. There have to be a lot of ghosts roaming around this place. It was building by Douglas Fairbanks and Mary Pickford in 1919 and was one of the most luxurious houses ever at the time. As far as mansions go, I'm not sure that it's anything too spectacular "“ gardens, a pool, fountains, etc. I'm telling you, it's the ghosts that make this worth $60 million. Yes, I am a dork.

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.
