U.S. sales of previously occupied homes rose in February to the highest level in more than three years, further evidence of a sustained housing recovery that is benefiting the broader economy.

The National Association of Realtors said Thursday that sales increased 0.8 percent in February from January to a seasonally adjusted annual rate of 4.98 million. That was the fastest sales pace since November 2009, when a temporary home buyer tax credit had boosted sales. The February sales pace was also 10.2 percent higher than the same month a year ago.

Steady hiring and near-record-low mortgage rates have helped boost sales and prices in most markets. The Realtors’ group says the median price for a home sold in February was $173,600. That’s up 11.6 percent from a year ago.

More people are also starting to put their homes on the market, which could help sales in the coming months. The number of available homes for sale rose 10 percent last month, the first monthly gain since April. Still, the inventory of homes for sale was 19 percent below a year ago.

And even with the gains, sales remain below the 5.5 million that economists associate with healthy markets.

One concern is that few first-time buyers, who are critical to a sustainable housing recovery, are entering the market. They made up only 30 percent of sales in February. That’s well below the 40 percent typical in a healthy market.

Since the housing bubble burst more than six years ago, banks have imposed tighter credit conditions and required larger down payments. Those changes have left many would-be buyers unable to qualify for super-low mortgage rates. First-time buyers have been hit particularly hard by the changes.

The average rate on the 30-year fixed mortgage dropped in November to 3.31 percent, the lowest on records dating back to 1971, and they have remained near that record low this year. This week the rate on the 30-year loan was 3.54 percent.

Rising demand and short supplies have encouraged builders to boost construction. U.S. builders started more houses and apartments in February and received building permits for future construction at the fastest pace in 4½ years.

The increases meant that builders broke ground on homes last month at a seasonally adjusted annual rate of 910,000, the second fastest pace since June 2008. Applications for building permits rose 4.6 percent to 946,000, the highest level since June 2008.
