Of course, the positive report was buoyed by the government's tax credit program, which refunded as much as $8,000 for homebuyers. With that program now over, markets could cool.
"We all know what happened to housing after the homebuyers tax credit ended," said Mike Larson, real estate analyst for Weiss Research. "It's been an Acapulco-sized cliff-dive."

In fact, home prices across the country could be substantially lower a year from now, according to Pat Newport, an analyst with IHS Global Insight. "It's now apparent that the demand for housing is a lot weaker than anyone thought," he said.
That has resulted in a glut of inventory, which a slew of bank repossessions of foreclosed properties is only making worse. Plus job gains are still proving elusive.
"These three factors are enough to bring home prices down," Newport said.
