Applications for U.S. home mortgages fell for a second week and hit a 13-year low as mortgage rates rose due to a bond market sell-off following the Federal Reserve's decision to pare its bond purchase stimulus in January, according to the Mortgage Bankers Association, Reuters reported. The association's seasonally adjusted index of mortgage application activity, which includes both refinancings and home purchases, fell 6.3 percent to the lowest level since December 2000.
