WASHINGTON – Contracts for US home resales hit a 2-1/2 year high in November and factory activity in the Midwest expanded this month, suggesting some strength in the economy despite the threat of tighter fiscal policy. The National Association of Realtors said Friday that its seasonally adjusted pending home sales index rose 1.7 percent in November from October to 106.4. That's the highest since April 2010, when a homebuyer tax credit caused a spike in sales. And after excluding those months when the tax credit was available, it's the best reading since February 2007. The increase followed a 5 percent gain in October and suggests higher sales of previously occupied homes in the coming months. There's generally a one- to two-month lag between a signed contract and a completed sale. In November, signed contracts to buy homes rose in the Northeast and West, and ticked up slightly in the Midwest. They were unchanged in the South. Home sales are on track to rise 10 percent this year to their highest level in five years, buoyed by ultra-low mortgage rates and steady job gains. The Realtors' group forecast that sales may rise in 2013 to about 5.1 million. That's still below the more than 5.5 million that is considered consistent with a healthy market. The housing recovery that began earlier this year is looking sustainable for a number of reasons. The supply of previously occupied homes for sale has finally thinned out and is at an 11-year low. At the same time, more people are looking to buy or rent a home after living with relatives or friends during and in the aftermath of the Great Recession. The combination of stronger demand and limited supply is pushing up home prices. That could encourage more sellers to put their homes on the market because they can expect a better price. Builders are also more optimistic that the recovery will endure and are stepping up construction. — AP
