A chorus of voices is giving hope to the housing industry, which is starting to show signs of recovery. Demand for housing, as measured by pending home sales, was at a two-year peak in October, according to the National Association of Realtors. Builders broke ground on 894,000 housing units that same month, their fastest pace in four years, according to the U.S. Commerce Department. The National Association of Home Builders (NAHB), which surveys its members every month, declared that its Builder Confidence Index hit its highest level in November since May 2006.
