Austin-area sales of existing homes hit the highest level in a year last month, according to figures Monday from the Austin Board of Realtors.

Last month, 2,135 single-family homes were sold in the area, down 4 percent from a year earlier. That was the smallest decline since a 2 percent drop in July 2007, when the market began to soften amid an emerging national mortgage crisis.

This year, sales were down 19 percent in May and 18 percent in April from a year earlier.

Pending sales — those in the pipeline to close in July — were up 4 percent, to 2,084.

We've seen the year-over-year gap in sales volume close steadily throughout 2009, and that momentum continues this month, said Jay Gohil, chairman of the Board of Realtors.

Jim Gaines, research economist for the Real Estate Center at Texas A&M, said there's not yet a clear signal that the Austin market has hit bottom.

That's the $64 million question, he said.

He said Texas is seeing more signs that the recession has landed with full force, such as a weakening job market — including in Central Texas — and falling sales tax revenue.

But there is growing evidence nationwide that the housing market is starting to stabilize. Combined, sales of new and existing homes hit an annual rate of 5.1 million in May, the highest level this year.

In Central Texas, the market is benefiting from low mortgage rates and a healthy supply of homes for sale. Another strong incentive: an $8,000 federal tax credit for first-time buyers who close on a home before Dec. 1.

But the market faces a long climb back. Home sales last month were down 23 percent from June 2007.

Mark Sprague, Austin partner for Residential Strategies Inc., which tracks the housing market, said the Austin market appears to be improving.
