From Harrison Ford to Sean “Diddy” Combs to the late Elizabeth Taylor, there are true mega-star homes on the market right now, and these incredible properties reflect the success of their owners.

Interestingly, when it comes to the most famous celebrities, real estate may be one of the few non-inflated things you can buy. You can buy a mid-1970s Rolex Submariner 55XX series for under $5000, but the same watch, except that it was worn by actor Steve McQueen, went for over a quarter of a million dollars. Likewise, JFK’s cigar humidor fetched more than half a million dollars at auction, and it takes up about a square foot of real estate. So in a world obsessed with celebrity, where provenance can increase values hundreds or thousands of times, celebrity homes, which get only slightly inflated by their history, might seem like a bargain in comparison. Of course, when you go to sell, you’ll find the same lack of celebrity appreciation disappointing, but in the meantime, at least you can throw great parties in a mansion where one of the most famous people on the planet once threw parties.
