Existing-home sales declined in July from an upwardly revised June pace but are notably higher than a year ago, according to the National Association of Realtors.  Monthly gains in the Northeast and Midwest were offset by declines in the West and South.

Total existing-home sales fell 3.5 percent to a seasonally adjusted annual rate of 4.67 million in July from 4.84 million in June, but are 21.0 percent above the 3.86 million unit pace in July 2010, which was a cyclical low immediately following the expiration of the home buyer tax credit.

Lawrence Yun, NAR chief economist, said there is a tug on the market. “Affordability conditions this year have been the most favorable on record dating back to 1970, but many buyers are being held back because banks are offering financing to only the most highly qualified borrowers, ignoring a large share of otherwise creditworthy buyers,” he said. “Those potential buyers represent the difference between an uneven recovery and a much more robust housing market that could stimulate additional economic activity and create jobs.”

According to Freddie Mac, the national average commitment rate for a 30-year, conventional, fixed-rate mortgage was 4.55 percent in July, up from 4.51 percent in June; the rate was 4.56 percent in July 2010.  Last week, Freddie Mac reported the 30-year fixed rate dropped to 4.32 percent.

NAR President Ron Phipps, broker-president of Phipps Realty in Warwick, R.I., said an unacceptably high number of potential home buyers are unable to complete transactions. “For both mortgage credit and home appraisals, there’s been a parallel pendulum swing from very loose standards which led to the housing boom, to unnecessarily restrictive practices as an overreaction to the housing correction,” he said.

“Beyond the tight credit problems, all appraisals must be done by valuators with local expertise and using reasonable comparisons – it doesn’t make sense to consistently see so many valuations coming in below negotiated prices, often below replacement construction costs,” Phipps said.

The national median existing-home price for all housing types was $174,000 in July, down 4.4 percent from July 2010. Distressed homes – foreclosures and short sales typically sold at deep discounts – accounted for 29 percent of sales in July, compared with 30 percent in June and 32 percent in July 2010.

Total housing inventory at the end of July fell 1.7 percent to 3.65 million existing homes available for sale, which represents a 9.4-month supply at the current sales pace, up from a 9.2-month supply in June.

All-cash sales accounted for 29 percent of transactions in July, unchanged from June; they were 30 percent in June 2010; investors account for the bulk of cash purchases.

First-time buyers purchased 32 percent of homes in July, up from 31 percent in June; they were 38 percent in July 2010. Investors accounted for 18 percent of purchase activity in July compared with 19 percent in June and 19 percent in July 2010. The balance of sales was to repeat buyers, which were a 50 percent market share in July, unchanged from June.

Single-family home sales declined 4.0 percent to a seasonally adjusted annual rate of 4.12 million in July from 4.29 million in June, but are 21.5 percent above the 3.39 million level in July 2010. The median existing single-family home price was $174,800 in July, down 4.5 percent from a year ago.

Existing condominium and co-op sales were unchanged at a seasonally adjusted annual rate of 550,000 in July, and are 17.3 percent above the 469,000-unit pace one year ago. The median existing condo price was $168,400 in July, down 4.0 percent from July 2010.

Regionally, existing-home sales in the Northeast rose 2.7 percent to an annual level of 750,000 in July and are 19.0 percent above July 2010. The median price in the Northeast was $245,600, down 6.8 percent from a year ago.

Existing-home sales in the Midwest increased 1.0 percent in July to a pace of 1.05 million and are 31.3 percent above a year ago. The median price in the Midwest was $146,300, down 2.9 percent from July 2010.

In the South, existing-home sales declined 1.6 percent to an annual level of 1.84 million in July but are 19.5 percent above July 2010. The median price in the South was $152,600, which is 2.2 percent below a year ago.

Existing-home sales in the West fell 12.6 percent to an annual pace of 1.04 million in July but are 16.9 percent above a year ago. The median price in the West was $208,300, down 7.1 percent from July 2010.
