Aspen, Colorado is a special place. And you need a lot of money to live here. There are 88 homes listed on the market for $20 million or more. Those are just the ones officially listed. But even here, the economic slowdown is starting to affect prices. They’re falling, by one estimate 5 percent, helped, in part, by foreign lookie-loos coming in to take advantage of the cheap dollar.

But price is almost secondary now to size. During the ‘90s, there was a McMansion boom in this town. One home is 55,000 square feet! (Prince Bandar’s, and he’s been trying to sell it forever—for $135 million). The county grew concerned and began limiting the size of new homes. The size limit keeps coming down, and currently, no new home can be built bigger than 5,750 square feet, including the basement and garage.
