Home prices may have hit bottom in early 2012, but the housing recovery still has a long way to go. In fact, home values may not exceed their prerecession peak until the early part of 2018, according to a quarterly survey of more than 100 experts sponsored by Zillow.

"We've reached a point in the recovery where the only real cure-all is time," Zillow Chief Economist Stan Humphries said. The survey included economists, real estate professionals, investment and market strategists, and was conducted for Zillow by Pulsenomics LLC.
