The second monthly release of the NAHB/First American Improving Markets Index (IMI) on Oct. 5 showed that 23 individual housing markets were “improving,” nearly double the 12 markets on the list in September. The index identifies metropolitan areas that have shown improvement for at least six months in housing permits, employment and housing prices.

“Both the number and geographic diversity of improving housing markets expanded this month, with Iowa, Illinois and South Carolina all newly represented by one entry or more on the list,” NAHB Chairman Bob Nielsen told Nation’s Building News. “This is further evidence that, despite the tough conditions that persist in many cities, pockets of improvement are emerging in local housing markets across the country,” he said.
