Compare what kind of house you can get for $600,000 in six markets across the country. We start in Nashville, Tenn., with a midcentury brick ranch that has a newly renovated master suite and kitchen. From there it's off to Indianapolis, Ind., and a lovely contemporary on a wooded acre, followed by a modern retreat on a hill west of Austin, Texas. Last up is a look at homes in Albuquerque, N.M., Gainesville, Fla., and Baltimore, Md.
