The National Association of Realtors is celebrating some good numbers out today: Existing-home sales – including single-family, townhomes, condominiums and co-ops – surged 10.1 percent to a seasonally adjusted annual rate 1 of 6.10 million units in October from a downwardly revised pace of 5.54 million in September, and are 23.5 percent above the 4.94 million-unit level in October 2008. Sales activity is at the highest pace since February 2007 when it hit 6.55 million. Lawrence Yun , NAR chief economist, was surprised at the size of the gain. “Many buyers have been rushing to beat the deadline for the first-time buyer tax credit that was scheduled to expire at the end of this month, and similarly robust sales may be occurring in November,” he said. “With such a sale spike, a measurable decline should be anticipated in December and early next year before another surge in spring and early summer.” Read the full release here . Meanwhile, the Morgage Bankers Association focuses on a different set of housing market statistics from last quarter: The delinquency rate for mortgage loans on one-to-four-unit residential properties rose to a seasonally adjusted rate of 9.64 percent of all loans outstanding as of the end of the third quarter of 2009, up 40 basis points from the second quarter of 2009, and up 265 basis points from one year ago, according to the Mortgage Bankers Association’s (MBA) National Delinquency Survey. The non-seasonally adjusted delinquency rate increased 108 basis points from 8.86 percent in the second quarter of 2009 to 9.94 percent this quarter. And MBA Chief Economist Jay Brinkmann says the news is only going to get worse in those regions of the country hardest hit so far, like Arizona, California, Florida, and Nevada: First, it is unlikely the employment picture will get better until sometime next year and even then jobs will increase at a very slow pace. Perhaps more importantly, there is no reason to expect that when the economy begins to add more jobs, those jobs will be in areas with the biggest excess housing inventory and the highest delinquency rates. Second, the number of loans 90 days or more past due or in foreclosure is now a little over 4 million as compared with 3.9 million new and previously occupied homes currently for sale, although there is likely some overlap between the two numbers. The ultimate resolution of these seriously delinquent loans will put added pressure on the hardest hit sections of the country. Read the MBA's release here .
