California rebound boosts 20-city home price index.

LOS ANGELES — A surprisingly strong rebound in California's real estate market helped lift a key home price index for the eighth month in a row.

That's good news for people who plan to sell their homes this spring. Prices are now up almost 4 percent from the bottom in May 2009, but still almost 30 percent below the May 2006 peak.

Prices rose 0.3 percent from December to January on a seasonally adjusted basis, according to the Standard & Poor's/Case-Shiller 20-city home price index released Tuesday. Prices increased in 12 cities in the index.

The biggest monthly gain was in Los Angeles, where prices rose 1.8 percent from December. And real estate agents say there's a distinct sense the worst of the downturn is over.

Prices in San Diego, meanwhile, rose by almost 0.9 percent. Phoenix had the third-largest gain at 0.8 percent.

Rising home prices also could boost consumer optimism. For most Americans, their home is their largest asset, so as values climb from the depths of the housing bust, homeowners feel wealthier and more comfortable spending. And, for homeowners who owe more on their mortgages than their properties are worth, rising prices rebuild equity.

Still, shoppers remain cautious and there are signs that last year's housing rebound won't last. Home sales sank during the winter, and government incentives that have propped up the market are ending.

However, bargain-hunting homebuyers continue to pack open houses in California, often facing off with investors for foreclosed homes.

"We're seeing multiple offers in most of the markets here in the San Francisco Bay area," said David Kerr, an agent with ZipRealty in Oakland, Calif. "People are getting off the fence."

With such high demand, supply is dwindling, driving prices higher.

California home sales will likely get a boost in coming months thanks to a new serving of government stimulus.

Last week, state lawmakers enacted a tax credit of up to $10,000 for homebuyers that kicks in May 1. The state allotted $100 million for first-time buyers and another $100 million to anyone who buys a newly built home. California had a round of tax credits last year that proved to be popular; that program ended in July.

Still, there remain pockets of weakness. Sales of homes priced above $500,000 are sluggish. And despite rising prices, more than one-third of all homeowners with a mortgage still owe more on their loans than their homes are worth, according to First American CoreLogic.

Many analysts expect the Case-Shiller 20-city index will again turn downward in the coming months as more foreclosures in other states hit the market.

"It is only a matter of time before the index records a double-dip in prices," wrote Paul Dales, U.S. economist with Capital Economics, who forecasts a 5 percent drop. The market will be tested in the second half of the year, he wrote, when a tax credit that has boosted sales is gone.
