23 Aug 2006, Los Angeles, California, USA — A home for sale with an open house sign in Los Angeles. A slowdown in the once-sizzling housing market is spreading, with 28 states and the District of Columbia reporting spring sales declines, led by big drops in former boom areas of Arizona, Florida and California. Nationally, sales were down 7 percent in the April-June quarter this year compared with the same period in 2005, the National Association of Realtors said in its latest state-by-state look at housing conditions around the country. — Image by © Marianna Day Massey/ZUMA/Corbis
