PASADENA, CA - APRIL 23:  A sign advertises a house for sale on April 23, 2009 in Pasadena, California. About half of all homes sold last month were sold to first-time homebuyers but hopes of a Spring recovery in the housing market were dampened by a report by the National Association of Realtors that existing home sales fell 3 percent in March despite near-record-low mortgage rates and home prices that are the lowest in years. The median sales price in March was $175,200, down from $200,000 a year ago.  (Photo by David McNew/Getty Images)
