Well RobJ... I'd like to see some data/stats on what the political affiliation is for the people that did this. I don't have it, so I will refrain from commenting about it. I suspect it would be very interesting.
First thing I ever did was to pay off the mortgage as fast as I could. Took 20 years, but I did it. No matter what happens I am gonna have a roof over my head.
That is what my family members did. There were Carter Presidency APRs of 18% then that encouraged the same.
Older family members built one part of the home at a time, living in the basement while they finished the upstairs, and then would add on as they had the money to do so. They never used loans. The lumber from my grandparent's home was from a large one room school house that they torn down.
The older Americans that I know now that owe on homes either choose to do so due to low APRs, having enough cash that they could pay off the home, or they got them self into a situation in which they found themselves upside down. The upside down thing happened a lot to people when they moved to Nevada with the hopes of selling their home and buying a smaller home when they retired.
A lot of people just don't value home ownership and figure they will either always have a mortgage or rent payment. Different priorities I guess. I don't think it has much to do with political affiliation.
