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, 1 year ARMs as well as application volume for 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 increased 3 basis point since last week to 5.78% while the purchase application volume increased by 8.1% and the refinance application volume increased 3.4% compared to last week’s results.
It’s important to note that all application volume values reflect only “initial” applications NOT approved applications… i.e. originations…
Also important to note, the average 30 year fixed mortgage rate has decreased significantly in the last few weeks but still remain just under the mean seen during 2007 while the interest rate for an 80% LTV 1 year ARM jumped significantly and now rests 128 basis points above the rate of an average 80% LTV 30 year fixed rate loan.
It’s important to note that the data is reported (and charted) weekly and that the rate data represents average interest rates, and the index data represents mortgage loan application volume for home purchases, home refinances and a composite of all loans.
