"Construction on single-family homes jumped to an annualized rate of 11 percent in August the strongest pace since August 2008. Over the first nine months of the year single-family starts were 23 percent higher than the same period last year. Moreover homebuilder confidence rose for the sixth consecutive month in October to the highest level since June 2006 according to the NAHB/Wells Fargo Housing Market Index."
