The National Association of Realtors (NAR) reported that its pending home sales index, a forward-looking indicator based on contracts signed, rose 6.3% to 87.7 in December 2008. NAR chief economist Lawrence Yun said the index shows a modest rebound. “The monthly gain in pending home sales, spurred by buyers responding to lower home prices and mortgage interest rates, more than offset an index decline in the previous month,” he said.
