The average 30-year fixed-rate mortgage rose from 3.93 percent last week to 4.46 percent this week; the highest it has been since the week of July 28, 2011. This represents the largest weekly increase for the 30-year fixed since the week ended April 17, 1987.
After hovering around record lows for the past few years, mortgage rates are rising dramatically. That has consumers not only shopping more but also considering adjustable rate mortgages, which offer lower rates and lower monthly payments.
These ARMs, many requiring interest payments only, were popular during the latest housing boom but quickly fell out of favor when safer, fixed-rate loan rates fell to record lows.
