In Freddie Mac's results of its Primary Mortgage Market Survey the 30-year fixed-rate mortgage averaged 5.14 percent for the week ending August 27, up from the previous week when it averaged 5.12 percent.
      Last year at this time, the 30-year fixed-rate mortgage averaged 6.40 percent. 
      Low rates contributed to existing home sales rising for the fourth consecutive month to an annual.  Add the Tax Credit to the low mortgage rates and now is a GREAT time to buy.
