Damage from the housing bust is spreading to areas once thought to be immune.
In at least 14 major U.S. metro areas, prices have fallen to 2003 levels -- when the housing bubble was just starting to inflate. Prices likely will drop further this year, making many people reluctant to buy or sell and pushing down sales and prices more.
The depressed housing industry is slowing an economy that has shown strength elsewhere. And it's starting to hurt those who bought years before the housing boom began. In some cities, people who have paid their mortgages for a decade have little or no home equity.
Prices have tumbled in familiar trouble spots, such as Las Vegas, Cleveland and Detroit. But they're also at or near 10-year lows in Denver, Atlanta, Chicago and Minneapolis -- cities that weren't as swept up in the housing boom and bust.
"It's been tough on the lower class, but it's filtering up," said Paul Dales, senior U.S. economist with Capital Economics. "It may be only a matter of time before it hits the wealthy."
For Washington, the median resale price in the fourth quarter of 2010 was $239,000, a drop of 2 percent from a year ago, the Washington Center for Real Estate Research reported.
But the center said Benton and Franklin counties showed a 9.4 percent increase from a year ago in the fourth quarter, with a median home resale price of $182,400.
Prices fell from December to January in all but one of the 20 cities tracked by the Standard & Poor's/Case-Shiller home price index. The index dropped for a sixth straight month. Prices in 11 of the cities are at their lowest point since the housing bubble burst.
The report measures prices relative to those in January 2000. For each of the 20 metro areas it studies, it provides an updated three-month average price.
The Seattle Times reported that Case-Shiller figures for the Seattle metropolitan area show home prices are back where they were in September 2004. Prices fell 2.4 percent between December and January, the second-steepest drop among the 20 markets the index tracks. Seattle-area home prices were down 6.7 percent for the year.
"The housing market recession is not yet over, and none of the statistics are indicating any form of sustained recovery," said David M. Blitzer, chairman of the Index Committee at Standard & Poor's.
Just about the only major market weathering the second wave of the housing downturn is Washington, D.C. Home prices there have risen 11 percent in the past two years.
Weak home sales and falling prices are imposing a heavy burden on the economy, which has gained strength from higher consumer spending. Applications for unemployment benefits are at prerecession lows. Manufacturing activity is growing at its fastest rate in seven years.
By contrast, sales of previously occupied homes are coming off their worst year in more than a decade. And new homes are selling at the slowest pace on records dating to 1963.
In part, the weakening prices show how much a home-buying tax credit stimulated sales in late 2009 and early 2010. Once those tax credits expired in April, many markets began a decline. Some economists say the tax credits merely postponed the bottoming out that's occurring now.
Millions of foreclosures and short sales largely are to blame. Short sales occur when lenders let homeowners sell for less than they owe on their mortgage. Those cut-rate sales have left a glut of discounted properties in many markets. Prices won't stop falling until they are cleared.
Even though foreclosures and short sales have created a surplus of homes for sale, many of them are undesirable. The supply of homes that people actually want to buy -- and can afford -- is much narrower.
