WASHINGTON – The effects of falling rates in the Treasury bond market, concern about a possible war with Iraq, and the decision two weeks ago by Federal Reserve Chairman Alan Greenspan to cut interest rates came together last week to cause 30-year mortgages rates to fall to a record low of 5.94%. The record-low rate was down from 6.11%, reported by Freddie Mac, and it was the lowest rate since the agency began tracking 30-year mortgage rates in 1971. Rates for 15-year fixed-rate mortgages also fell to a new low last week – 5.32%. The previous week's rate of 5.48% was the lowest level for 15-year fixed rate mortgages since Freddie Mac began tracking these rates in 1991.
