Ever since the 2008 crash, mortgage rates have plunged lower and lower, providing some relief in an otherwise tight 5 years economically. This week they hit another low, based on’s weekly survey. (It has been tracking rates for 26 years, and at 3.5%, this is the lowest rate on a 30-year mortgage yet.)

The cause of these record lows seems to be a flight to bonds due to Fiscal Cliff worries and the continued Operation Twist by the Fed.

Additional good news is that many more homeowners can refinance now, even if their home is worth less on paper than they owe. The government’s HARP 2 program has been a huge help in this area.
