Reading Rates: MBA Application Survey – January 28 2009

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 decreased 2 basis points since last week to 5.22% while the purchase application volume declined 2.90% and the refinance application volume simply collapsed dropping 48.03% compared to last week’s results.

It’s important to note though that although the steady decline in mortgage rates has likely played a significant role in the large increases in refinance application volume seen recently, it’s also altogether possible that the MBAA has some difficulty in seasonally adjusting their numbers around the November to January periods.

As you can see on the charts below, November through January usually brings some erratic spikes to the volume indices but the cause, at least in some part, is likely the result of troubles seasonally adjusting a noisy weekly series and not an actual spontaneous doubling of refinance activity.

As was noted last year, it’s probably sensible to wait until February to draw a final conclusion.

The following chart shows how the principle and interest cost and estimated annual income required to cover the PITI (using the 29% “rule of thumb”) on a $400,000 loan has changed since November 2006.
