Location: Miami Beach, Fla.
The Skinny: No, this isn't a $21M double-wide trailer, but it is an opulent 18,000-square-foot Miami Beach mansion that sits on a double lot overlooking Indian Creek. Sorry for the mix-up mobile home fans, but this sprawling Floridian might have a bit more breathing room than you're accustomed to. With 13 bedrooms, 12.5 bathrooms, dock space for a 100-foot yacht, a five-car garage, and a two-acre lot, this is quite the waterfront estate. A palm tree-lined swimming pool with cabana is the crowning jewel, like something out of a Slim Aarons photo.
