Sales of existing-home sales rose 3.7 percent in March, according to the National Association of Realtors. Existing-home sales rose to a seasonally adjusted annual rate of 5.10 million in March from an upwardly revised 4.92 million in February.

Lawrence Yun, NAR chief economist, expects the improving sales pattern to continue.  “Existing-home sales have risen in six of the past eight months, so we’re clearly on a recovery path,” he said. “With rising jobs and excellent affordability conditions, we project moderate improvements into 2012, but not every month will show a gain – primarily because some buyers are finding it too difficult to obtain a mortgage. For those fortunate enough to qualify for financing, monthly mortgage payments as a percent of income have been at record lows.”

NAR’s housing affordability index shows the typical monthly mortgage principal and interest payment for the purchase of a median-priced existing home is only 13 percent of gross household income, the lowest since records began in 1970.

Distressed homes – typically sold at discounts in the vicinity of 20 percent – accounted for a 40 percent market share in March, up from 39 percent in February and 35 percent in March 2010.
