MBA: Mortgage rates flat at 3.66 percent

Mortgage rates went flat at 3.66 percent since last week, according to the latest mortgage rates data from the Mortgage Bankers Association. 

The Mortgage Bankers Association (MBA) publishes the results of a weekly applications survey that covers roughly 50 percent of all residential mortgage originations and tracks the average interest rate for 30 year and 15 year fixed rate mortgages as well as the volume of both purchase and refinance applications. 

The purchase application index has been highlighted as a particularly important data series as it very broadly captures the demand side of residential real estate for both new and existing home purchases. 

The latest data is showing that the average rate for a 30 year fixed rate mortgage (from FHA and conforming GSE data) went flat at 3.66% since last week while the purchase application volume declined a notable 5% and the refinance application volume declined 3% over the same period.
