The unsteady housing market is showing a rare sign of strength: waiting home sales were up significantly in February, a report released Monday said, suggesting that Americans took advantage of a tax credit for home buyers.

Sales rose 8.2 percent in February, the National Association of Realtors(房地产经纪人) said. Analysts had expected sales to stay flat.

Economists said Monday’s data suggested buyers were re-entering the market as the April 30 deadline approached for a government tax credit of up to $8,000. The tax credit drove up sales rapidly in the fall, when it was originally set to end, but it has been slow to push the market this spring.

Lawrence Yun, chief economist for the association, said Monday’s report “may signal the early stages of a second wave of home sales.”

A separate report on Monday showed the service division in the United States was improving, driven in part by gains in employment.

The Institute for Supply Management’s non-manufacturing barometer(晴雨表) rose to 55.4 in March, up from 53 in February, going beyond expectations. Much of the energy came from a rush in new orders and business activity.

It was the highest reading(测量或调查的读数) for the survey since May 2006. While employment rose, it was short of the break-even point, signaling the service division was still losing jobs. Exports also rose significantly.

“This is a very encouraging report, which indicates acceleration in demand growth from both domestic and foreign customers,” Barclays Capital researchers wrote in a note on Monday.

The jump in waiting home sales was a rare bit of good news for the housing market, which remains in a deep rut(车辙). Home prices have shown little change.

Analysts expect the housing market to gradually improve as unemployment becomes less and the broader recovery gains steam. But so far, relief has been slow to come.

Monday’s report showed sales rose even in areas hit hard by poor weather in February. Sales climbed 9 percent in the Northeast and South, which were blanketed by snow in February.

The Realtors association bases its data on signed contracts, which usually take one or two months to translate into final sales.
