Compare what kind of house you can get for $400,000 in six markets across the country. First up is a visit to a pair of Chicago designers who live and work in their four-story townhome. Next, a couple of married architects have revived a Providence, R.I., Victorian with a few modern touches. Then, in Asheville, N.C., we'll tour a minimalist loft decorated with found objects. Last up is a quick look at homes in Modesto, Calif., St. Louis, and Spokane, Wash.
