Existing home sales nationally were down in March but continue to outpace year-ago levels, while inventory tightened and home prices are showing further signs of stabilizing, 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, declined 2.6 percent to a seasonally adjusted annual rate of 4.48 million in March from an upwardly revised 4.60 million in February, but are 5.2 percent above the 4.26 million-unit pace in March 2011.

Lawrence Yun, NAR chief economist, said the recovery is in the process of settling into a higher level of home sales. “The recovery is happening though not at a breakout pace, but we have seen nine consecutive months of year-over-year sales increases,” he said. “Existing-home sales are moving up and down in a fairly narrow range that is well above the level of activity during the first half of last year. With job growth, low interest rates, bargain home prices and an improving economy, the pent-up demand is coming to market and we expect housing to be notably better this year.”

Total housing inventory at the end of March declined 1.3 percent to 2.37 million existing homes available for sale, which represents a 6.3-month supply at the current sales pace, the same as in February. Listed inventory is 21.8 percent below a year ago and well below the record of 4.04 million in July 2007.

“We were expecting a seasonal increase in home listings, but a lack of inventory has suddenly become an issue in several markets with not enough homes for sale in relation to buyer interest,” Yun said. “Home sales could be held back because of supply factors and not by demand—we’re already seeing this in the Western states and in South Florida.”
