Total existing-home sales, which are completed transactions that include single-family homes, town homes, condominiums and co-ops, rose 7.8% to a seasonally adjusted annual rate of 4.82 million in August from 4.47 million in July, and are 9.3% higher than the 4.41 million-unit level in August 2011.
Lawrence Yun, NAR chief economist, said favorable buying conditions get the credit.
"The housing market is steadily recovering with consistent increases in both home sales and median prices," Yun said. "More buyers are taking advantage of excellent housing affordability conditions."
"Inventories in many parts of the country are broadly balanced, favoring neither sellers nor buyers," he added. "However, the West and Florida markets are experiencing inventory shortages, which are placing pressure on prices."
According to Freddie Mac, the national average commitment rate for a 30-year, conventional, fixed-rate mortgage rose to 3.60% in August from a record low 3.55% in July; the rate was 4.27% in August 2011.
"The strengthening housing market is occurring even with difficult mortgage qualifying conditions, which is testament to the sizable stored-up housing demand that accumulated in the past five years," Yun added.
The national median existing-home price for all housing types was $187,400 in August, up 9.5% from a year ago.
The last time there were six back-to-back monthly price increases from a year earlier was from December 2005 to May 2006. The August increase was the strongest since January 2006 when the median price rose 10.2% from a year earlier.
Distressed homes, which include foreclosures and short sales sold at deep discounts, accounted for 22% of August sales, down from 24% in July and 31% in August 2011. Foreclosures sold for an average discount of 19% below market value in August, while short sales were discounted 13%.
Total housing inventory at the end of August rose 2.9% to 2.47 million existing homes available for sale, which represents a 6.1-month supply at the current sales pace, down from a 6.4-month supply in July. Listed inventory is 18.2% below a year ago when there was an 8.2-month supply.
The median time on market was 70 days in August, consistent with 69 days in July but down 23.9% from 92 days in August 2011. Homes sold in August were on the market for less than a month, accounting for 32%, while 19% were on the market for six months or longer.
NAR President Moe Veissi, broker-owner of Veissi & Associates Inc. in Miami, said some buyers are involuntarily sidelined.
"Total sales this year will be 8 to 10% above 2011, but some buyers are frustrated with mortgage availability," he said. "If most of the financially qualified buyers could obtain financing, home sales would be about 10 to 15% stronger, and the related economic activity would create several hundred thousand jobs over the period of a year."
First-time buyers accounted for 31% of purchasers in August, down from 34% in July. They were 32% in August 2011.
All-cash sales were unchanged at 27% of transactions in August; they were 29% in August 2011. Investors, who account for most cash sales, purchased 18% of all homes in August, up from 16% in July. They were 22% in August 2011.
Single-family home sales rose 8.0% to a seasonally adjusted annual rate of 4.30 million in August from 3.98 million in July, and are 10.0% above the 3.91 million-unit pace in August 2011. The median existing single-family home price was $188,700 in August, up 10.2% from a year ago.
Existing condominium and co-op sales increased 6.1% to a seasonally adjusted annual rate of 520,000 in August from 490,000 in July, and are 4.0% above the 500,000-unit level a year ago. The median existing condo price was $176,700 in August, which is 3.3% higher than August 2011.
Regionally, existing-home sales in the West increased 8.3% to an annual level of 1.17 million in August but are unchanged from a year ago. With ongoing inventory shortages, the median price in the West was $242,000, which is 16.3% higher than August 2011.
Existing-home sales in the Northeast rose 8.6% to an annual pace of 630,000 in August and are also 8.6% above August 2011. The median price in the Northeast was $245,200, up 0.6% from a year ago.
