The Pending Home Sales Index, a forward-looking indicator based on contracts signed in September, rose 6.1 percent to 110.1 from 103.8 in August according to the National Association of Realtors. The reading is the eighth straight month of gains, and tbe highest level since December 2006, when it hit 112.8.

Lawrence Yun, NAR chief economist, said the momentum is based on homeowners “trying to beat the expiration of the [first-time homebuyer] tax credit at the end of this month.”

“Home values will stabilize sooner rather than over-correcting. That, in turn, will mean wealth stabilization for the vast number of middle-class families and lay the foundation for a durable economic recovery,” he added.

NAR estimates approximately 3 million renters are now financially well-qualified to buy a median-priced home. “As long as buyers do not overstretch and stay well within their budget, a sizable pent-up demand can be tapped among financially qualified potential buyers,” Yun said. “Although the tax credit is greatly reviving the existing home market, new-home sales may continue to struggle as home builders hold back production to drive down inventory. In addition, there remains an ongoing credit crunch for construction loans.”

The Pending Home Sales Index in the Northeast slipped 2.0 percent to 83.6 in September but remains 16.9 percent above September 2008.

In the South, pending home sales increased 4.9 percent to an index of 109.7 and is 22.8 percent above September 2008. In the West the index jumped 10.2 percent to 143.8 and is 23.7 percent above a year ago.
