Mortgage Rates

The 30 year mortage rate is on a rollercoaster ride:

It was a very important factor in buying our home, interest rates were at the 5.5% level then. (1 st week of February)

Last week the interest rate was at 6.08% and today it's 5.66%.
To give you an idea of the difference in payment for every interest rate level:(everything is quoted in "useless" dollars)
