Christ knows why millions more never jumped onto 10 year fixed mortgages at 2% or less, common sense told you that if it still dropped slightly the loss would be minimal but if interest rates went back to historical averages then you would be laughing. When I paid the 15% mortgage back in the day when rates fell we continued to pay the same as we had done in case they went back up. Cut our cloth to suit as a result paid mortgage off 8 years early and mortgage free at 39.
To many do not look at the figures over total length of mortgage instead of trying to pay off early and save a fortune
