Gross profit also improved, rising 150 basis points to 18.2% from 16.7% a year ago.Higher Mortgage Rates Slow Down SalesHousing was the best performing sector for stocks in 2012. It looked like 2013 might be a repeat until the Fed started talking about a possible taper in September. The taper worries sent treasury yields higher which, in turn, raised mortgage rates substantially off their lows.Higher mortgage rates put a crimp on housing sales starting over the summer. While the Fed didn't taper in September after all, and treasury yields have since gone down, mortgage rates still remain at least a point above their lows of 2012. "The fundamentals of the current housing recovery are firmly in place, supported by low inventory levels, an improving economy and positive demographic trends," said Jeffrey Mezger, CEO. "Given these factors, we believe that the recent slower pace of the recovery caused by an up tick in mortgage interest rates is a temporary effect, and we expect to see steady upward demand for housing as consumers adjust to both higher rates and pricing," he added.Shares Sold OffAfter shares soared to new multi-year highs over the past 2 years, investors got spooked by higher mortgage rates over the summer and shares have been trending lower since.KB Homes shares are off over 30% from their 2013 highs.The analysts believe that the housing market is in the beginning of a multi-year recovery.
