Southern California's thawing real estate market heated up in April when home sales hit their highest level in eight months as bargain hunters snapped up foreclosed properties, an industry tracker said Monday.

Last month, 15,615 new and previously owned houses and condominiums sold in the six-county region, up 22 percent from 12,808 sales in March, said La Jolla-based DataQuick Information Systems.

"It's looking as if the worst is behind us," said DataQuick analyst John Karevoll of the sales slide that began three years ago. "That's the likely scenario."

April's sales spike marks the fourth consecutive monthly increase. But sales in April fell 19 percent from a year ago.

Karevoll is optimistic because the March-to-April sales increase was abnormally large. DataQuick began record-keeping in 1988 and the March to April increase has averaged 1.2 percent, the company said.

"We're hearing that escrows that have been stacking up for the past half-year are starting to close," Karevoll said. "And that's got a lot to do with the fact that lenders are making some loans."

DataQuick said April's sales increase was most pronounced for homes priced under $500,000 and accounted for 66percent of the monthly gain. Most of that activity was in areas hard hit by foreclosures, most notably the Antelope Valley and Inland Empire.
