My wife and I did this. We have paid off our mortage once, but almost twice. I know that sounds confusing.
We claimed 2 or 3 deductions when we were allowed to do 6 or 8 or 10. Then we took our income tax return and paid off bills and put the remainder on the principal of our home. (We ended up with no debt except out home.) We were with in 12 months of paying off our home when my company required that I move. When they forced us to move we had to move to an area that was a lot more expensive.
We started over again and they forced us to move again and again to a much higher area. The last time we had to move was to southern California and that was twice as much. We finally paid off our home when I got a severance package, but I'd have rather kept my job. It was so nice to not have that humongus house payment.
We put a picture frame on the wall. As we paid off the debt on out home we would mark another line on the chart and were at the roof line when we were forced to move. Having that picture and picture frame on the wall was a great mental boost and incentive to save.
FYI: The first time we used our income tax return to pay down the debt on our home about $1100 paid off 42 payments of principle.
Good luck to you and yours.
