Home Prices Fell Faster in October

The decline in home prices accelerated and spread to more regions of the country in October, according to data released Wednesday.

Prices fell 6.1 percent from October 2006 in 20 large metropolitan areas, according to Standard & Poor’s/Case-Shiller indexes, compared with a 4.9 percent decline in September. On a monthly basis, prices fell 1.4 percent in October, the fastest they have declined in at least the last seven years.

During the boom, rising home prices increased consumer spending because people felt more wealthy and were able to borrow against their new home equity. Now that process is reversing itself, said Patrick Newport, an economist at Global Insight, a research firm outside Boston. “And the foreclosure rates are going to go up a little more. If prices are falling, you are more likely to default” because the house may be worth less than the mortgage on it.

“It has been surprisingly resilient,” Robert J. Shiller, the Yale economist and a creator of the home price indexes, said about the economy. He added that it was difficult to determine what impact the weakness in housing would have on the economy going forward.

“We are in uncharted territory,” he said. “This was the biggest housing boom we have ever seen.”

Edward E. Leamer, an economist at the University of California, Los Angeles, said the declines in Seattle and elsewhere should not be surprising because they were also caught up in the housing boom that was fueled by low interest rates and lax lending standards.

“Finance is not local,” he said as a counterpoint to the maxim that real estate is local. “The availability of mortgages at extremely easy terms affected every home in the United States.”
