“Mortgage rates increased to their highest level since March last week, leading to the largest single week drop in refinance applications this year,” said Mike Fratantoni, MBA’s Vice President of Research and Economics. “The refinance index has fallen almost 19 percent over the past two weeks and is back to its lowest level since late March. Purchase activity declined over the week but is still running about 10 percent above last year’s pace at this time.”

The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances ($417,500 or less) increased to 3.78 percent from 3.67 percent, with points decreasing to 0.39 from 0.41 (including the origination fee) for 80 percent loan-to-value ratio (LTV) loans.
