St. Louis St. Louis hosted the 1904 Summer Olympics so long ago that Realtor.com's Reynolds doubts the Games had any economic impact that remains to this day. "I think the effects really depend on how far back you're looking," she says. Realtor.com found that St. Louis median asking prices rose only a paltry 1.25% over the past year, to $166,000. The Gateway to the West has some things going for its housing market, though. For instance, the city's 7.5% May jobless rate beat America's 8.2% overall rate, while the number of local homes listed for sale on Realtor.com dropped 18.1% over the past year. Those factors are usually positive signs for future home-price appreciation.
