Generalizations of positive or negative news that you hear in the media should not distract you from actual housing prices in your market. There are different pockets of increased or decreased home values all throughout the country. Take Los Angeles for example. Housing prices are up in Bel Air & Beverly Hills, but there was a drop in Topanga and Malibu. This interactive map, thanks to Zillow.com, will show you how the housing market did by zip code from March, April, and May 2012.
