U.S. home sales rose last month to the highest level since February 2007 as buyers rushed to close deals before mortgage rates increased further.
Yet the gain could represent a temporary peak if higher rates slow sales in coming months.
Sales of previously occupied homes rose 1.7 percent to a seasonally adjusted annual rate of 5.48 million in August, the National Association of Realtors said Thursday. That level is consistent with a healthy market.
August sales reflect contracts signed in June and July, when mortgage rates were rising steadily. The Realtors' group cautioned that buyer traffic dropped off significantly in August. That points to fewer sales in the fall.
Higher rates could also depress home buying next year, the Realtors' said. The group forecasts that sales will average 5.2 million in 2014. That's still better than the 4.19 million sales in 2010, when the housing market bottomed.
"We should expect some giveback in sales over the next several months," said Thomas Feltmate, an economist at TD Economics.
Steady job gains and low mortgage rates have fueled a recovery in housing since early last year. But rates have risen since May and have begun to restrain housing's rebound.
The average rate on a 30-year fixed mortgage was 4.57 percent last week, near a two-year high and more than a full percentage point higher than in May. That's when Federal Reserve Chairman Ben Bernanke suggested that the Fed could soon scale back its $85-billion-a-month bond purchase program, which is intended to keep interest rates low.
On Wednesday, in a surprise, the Fed decided against reducing its bond purchases. It said one key reason for its decision was the sharp increase in mortgage and other interest rates. Pulling back on its bond purchases could have sent such rates even higher.
Many economists say the housing recovery should withstand the recent rate increase. Mortgage rates are still quite low by historical standards.
"While higher mortgage rates are likely to temper existing home sales over the coming months, it by no means will derail the housing recovery," Feltmate said.
Other figures in the report were mixed. "Distressed" sales, which include foreclosures and homes with mortgages that exceed the home values, made up just 12 percent of sales. That was down from 23 percent a year earlier.
That means that traditional sales have risen 31 percent in the past year, said Paul Diggle, an economist at Capital Economics.
At the same time, potential homebuyers, particularly first-time purchasers, still appear to have difficulty qualifying for loans.
All-cash sales accounted for 32 percent of purchases, up from 27 percent a year ago. First-time buyers made up only 28 percent of sales, down from 31 percent a year earlier.
First-time buyers usually propel housing recoveries. But in recent years, they've struggled to meet higher credit standards. Many lenders also now require higher down payments.
The supply of available homes remains tight, the Realtors' group said. There were 2.25 million homes for sale last month, down 6 percent from a year earlier.
Rising prices could encourage developers to build more homes. Last month, builders broke ground on the most single-family homes since February and sought the most permits to build those homes in more than five years.
Homebuilder confidence remained at its highest level in nearly eight years in September, according to a survey by the National Association of Home Builders. But builders are starting to worry that sales may slow in coming months if rates keep rising, the survey found.
