There's a trend in U.S. housing, albeit a very small one. Drawn to the prospect of financial freedom, a simpler lifestyle, and limiting one's environmental footprint, more buyers are opting to downsize -- in some cases, to spaces no larger than 600 square feet. Where are these homes, and how do buyers find them? In this series realtors help people find perfect compact kingdoms -- from full-time residences to seasonal getaways. Shoppers in each episode get to see three styles before they decide which is their best fit.
