If you have a few million dollars hanging around, there is a very nice estate up for auction in Novi. It was originally $18 million, but with it facing foreclosure, you can get it for less:

The estate is packed with princely perks: five bedroom suites, a bowling alley, steam room, wine vault and a media room with a herringbone leather floor. Outside: $5 million worth of landscaped waterfalls, a pool with a 60-foot-long water slide and a par-three golf hole.

If only I could remember where in the backyard I buried that can of money...
