An abrupt turn higher for mortgage interest rates caused weekly demand from both potential homebuyers and current homeowners to drop. Total mortgage application volume fell 5.1% last week compared with the previous week, according to the Mortgage Bankers Association's seasonally adjusted index.

The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances, $766,550 or less, increased to 6.36% from 6.14%, with points rising to 0.62 from 0.61, including the origination fee, for loans with a 20% down payment. That was the highest rate since August.

"In the wake of stronger economic data last week, including the September jobs report, mortgage rates moved higher," said Mike Fratantoni, chief economist at the Mortgage Bankers Association.

Applications to refinance a home loan, which had been surging for several months, fell 9% for the week but were still 159% higher than the same week one year ago. Last year at this time, mortgage rates were 131 basis points higher.

"Conventional loan refinances, which tend to have larger balances than government loans and hence are more responsive for a given change in mortgage rates, fell to a greater extent over the week," Fratantoni said.
