September existing-home sales declined modestly, but inventory continued to tighten and the national median home price recorded its seventh back-to-back monthly increase from a year earlier, according to the National Association of Realtors®.

Total existing-home sales, which are completed transactions that include single-family homes, townhomes, condominiums and co-ops, fell 1.7 percent to a seasonally adjusted annual rate of 4.75 million in September from an upwardly revised 4.83 million in August, but are 11.0 percent above the 4.28 million-unit pace in September 2011.

The market trend is up. Despite occasional month-to-month setbacks, we're experiencing a genuine recovery. More people are attempting to buy homes than are able to qualify for mortgages, and recent price increases are not deterring buyer interest. Rather, inventory shortages are limiting sales, notably in parts of the West.

According to Freddie Mac, the national average commitment rate for a 30-year, conventional, fixed-rate mortgage fell to a record low 3.47 percent in September from 3.60 percent in August; the rate was 4.11 percent in September 2011.

The national median existing-home price for all housing types was $183,900 in September, up 11.3 percent from a year ago. The last time there were seven consecutive monthly year-over-year increases was from November 2005 to May 2006.

Distressed homes - foreclosures and short sales sold at deep discounts - accounted for 24 percent of September sales (13 percent were foreclosures and 11 percent were short sales), up from 22 percent in August; they were 30 percent in September 2011. Foreclosures sold for an average discount of 21 percent below market value in August, while short sales were discounted 13 percent.

Total housing inventory at the end September fell 3.3 percent to 2.32 million existing homes available for sale, which represents a 5.9-month supply at the current sales pace, down from a 6.0-month supply in August. Listed inventory is 20.0 percent below a year ago when there was an 8.1-month supply.

The shrinkage in housing supply is supporting ongoing price growth, a pattern that could accelerate unless home builders robustly ramp up production.

The median time on market was 70 days in September, unchanged from August, but down 30.7 percent from 101 days in September 2011. Thirty-two percent of homes sold in September were on the market for less than a month, while 19 percent were on the market for six months or longer.

Some buyers who could easily afford a mortgage can't assume they'll get one. Home buyers need to be more focused on the mortgage process in the current environment where lenders and banking regulators are being risk averse. Shopping for competitive mortgage terms is a good idea, but it may be more important to find a bank that is willing to work with you given your credit history. Realtors® can often recommend lenders that may have more reasonable underwriting standards.

First-time buyers accounted for 32 percent of purchasers in September, compared with 31 percent in August; they were 32 percent in September 2011.

All-cash sales were at 28 percent of transactions in September, up from 27 percent in August; they were 30 percent in September 2011. Investors, who account for most cash sales, purchased 18 percent of homes in September, unchanged from August; they were 19 percent in September 2011.

Single-family home sales declined 1.9 percent to a seasonally adjusted annual rate of 4.21 million in September from 4.29 million in August, but are 10.8 percent higher than the 3.80 million-unit level in September 2011. The median existing single-family home price was $184,300 in September, up 11.4 percent from a year ago.

Existing condominium and co-op sales were unchanged at a seasonally adjusted annual rate of 540,000 in September, but are 12.5 percent above the 480,000-unit pace a year ago. The median existing condo price was $181,000 in September, which is 10.0 percent higher than September 2011.
