The total volume of mortgage applications submitted in the week ending August 6 ticked up a seasonally adjusted 0.6% from the previous week as interest in both refinance and purchase mortgages remained essentially flat, according to the Mortgage Bankers Association (MBA). The total volume of applications for purchase mortgages is now 34.1% below the same time last year, MBA said. At the same time, a separate survey measuring household mortgage application rose 1.4%. MBA found the volume of applications submitted for purchase mortgages rose 0.3% after the previous week's 1.5% growth. This fourth weekly gain was driven by rising interest in mortgages insured by the government (through FHA and VA). The volume of applications submitted for refinance ticked up 0.6% after rising 1.3% last week. The refinance share of mortgage application activity ticked up to 78.1%, from 78% last week. The Mortgage Maxx index, which adjusts data to reflect the number of households applying for a mortgage, showed household application activity rose 1.4% after slipping 2.9% the week before.
