Weekly mortgage rates dipped in Freddie Mac‘s (FRE) latest survey of data through October 1. The average 30-year fixed-rate mortgage (FRM) had a 4.94% interest rate with an average 0.7 point, down 10bps from 5.04% last week. The 15-year FRM averaged 4.36% with an average 0.6 point, down 10bps from 4.46% last week. The five-year Treasury-indexed hybrid adjustable-rate mortgage (ARM) averaged 4.42% with an average 0.6 point this week, down from 4.51% last week. The one-year FRM averaged 4.49% with an average 0.5 point this week, also down from 4.52% last week. A separate rate survey conducted by Bankrate.com of major US banks and thrifts indicated rates fell for a fifth week, dipping to their lowest levels since spring. The 30-year FRM slipped 11bps to 5.25%, while the benchmark 15-year FRM fell 10bps to 4.65% this week, according to Bankrate. “This is as good a time as any to refinance because Uncle Sam will make it more difficult and more expensive to refi in a few months,” said Bankrate’s Holden Lewis in weekly commentary.
