The City of Angels hosted the 1932 and 1984 Summer Games, but Realtor.com's Reynolds thinks that was too long ago to have much effect on home prices in a community as big as Los Angeles. "You definitely see the biggest impacts on the smaller cities," she says. Still, Reynolds was a student at the University of Southern California in Los Angeles during the Games and says the community did a good job of reusing the athletic facilities afterward for local sporting events. "They spread the Olympic events out throughout city and were able to use the infrastructure long after the Games ended," she says. According to Realtor.com, median Los Angeles list prices rose 6.1% over the past year to reach $350,000.
