Southern California was especially vulnerable to the real estate bubble, and the median prices of single family homes -- the point at which half of all homes are more expensive and half are cheaper -- plunged in many places. In Compton, the median of $385,000 dropped to $94,000 in 2009, but crawled back up to $185,000 by the end of last year. But low income areas aren't the only places where there's a comeback. In LA's Hancock Park, they're up 85 percent, in the Newport Coast of Orange County, they're up 80 percent. That means a lot of real estate action.
