Home mortgage applications dropped last week as purchases and refinance loan volume slowed and mortgage interest rates likely rose slightly, according to a weekly report published Wednesday morning by the Mortgage Bankers Association. The MBA’s market composite index lowered to 621.6 for the week ended May 16, a drop of 7.8% from one week earlier.

The home loan application index is calibrated to March 16, 1990; a reading of 621.6 means that application activity was roughly 6.2 times greater than when the index was first established.  Refinancing activity, usually the driver of overall application volume, fell 8.7% as mortgage rates appeared to have inched higher; the MBA said that average rates on a 30-year fixed rate mortgages rose 8 basis points during last week. Purchase application activity — usually used by economists to predict the direction of the housing market — feel 6.9%.

Surprisingly, FHA loan application activity took a sharp dip as well, falling 6.8%; the drop was one of the few weekly decreases posted for FHA applications so far this year.  The share of variable-rate mortgages as a portion of overall application activity continued to rise as well, hitting its first double-digit total this year at 10.0%, the MBA said.  For more information, visit  http://www.mortgagebankers.org
