A definitive rise in mortgage interest rates over the last month is keeping borrowers at bay. Loan application volume fell 3.2 percent last week from the previous week on a seasonally adjusted basis, according to the Mortgage Bankers Association. Volume is now skewing toward larger loans for more expensive homes.

Refinance applications, which are most rate-sensitive, decreased 5 percent from the previous week, seasonally adjusted to the lowest level since early September. They are still 4 percent higher compared with one year ago, when interest rates were slightly higher. The refinance share of mortgage activity now stands at 58.7 percent of total applications.
