Is paying off your mortage a #1 personal finance priority?
It is one thing to take the advice of some numb-skulls on a web site, it is another thing to take the advice of someone who is really wealthy. For myself, I enjoy a very low interest rate (less than 3%) and am aggressively paying down my mortgage.  One night I was contemplating slowing that down, and even the possibility of borrowing more to purchase another rental property. I went to bed and picked up Kevin O'Leary's book(Cold Hard Truth On Men, Women, and Money: 50 Common Money Mistakes and How to Fix Them), which I happened to be reading at the time.   The first line I read, went something like:  The best investment anyone can make is to pay off their mortgage early.  He then did some math with the assumption that the person was making a 3% mortgage payment.   Any conflicting advice has to be weighted against what Mr. O'Leary has accomplished in his life.  Mark Cuban also has a similar view on debt.  From what I heard, 70% of the Forbes richest list would claim that getting out of debt is a critical step to wealth building. My plan is to do that, pay off my home in about 33 (September '16) more weeks and see where I can go from there.
