The Pending Home Sales Index,* a forward-looking indicator based on contract signings, rose 8.2 percent to 88.8 in May from an upwardly revised 82.1 in April and is 13.4 percent higher than the 78.3 reading in May 2010. The data reflects contracts but not closings, which normally occur with a lag time of one or two months.

This is the first time since April 2010 that contract activity was above year-ago levels, and the monthly gain was the strongest increase since last November when the index rose 10.6 percent.

Lawrence Yun, NAR chief economist, said the improvement bodes well for home prices. "Absorption of inventory is the key to price improvement, and this solid gain in contract signings implies that home values in many localities are or will soon be stabilizing as inventories get absorbed at a faster pace," he said. "Some markets have made a rapid turnaround, going from soft activity to contract signings rising by more than 30 percent from a year ago, including areas such as Hartford, Conn.; Indianapolis; Minneapolis; Houston; and Seattle."

Pending home sales have trended up unevenly since bottoming last June, rising in seven of the past 11 months. "Home sales still could be 15 to 20 percent higher," Yun said. "If banks would simply return to normal sound underwriting standards and begin lending to more creditworthy borrowers, we'd get a much faster recovery in the housing sector."
