Finally. Record low mortgage rates spurred an uptick in new-purchase mortgage applications last week for just the second time in the past two months, while more Americans also applied to refinance, according to the Mortgage Bankers Association. Rates fell last week to 4.59% on an average 30-year fixed-rate mortgage, which is down from 4.69% one week ago and the lowest ever recorded by the trade group since its survey began in 1972. Other measures show that rates continued to fall this week: Zillow's Mortgage Marketplace quoted an average of 4.37% on Tuesday.
