I'm a bit more risk adverse but each person has a level of risk that works for them.
I could pay off my mortgage at any time, but I've earned more by putting that cash in equities.
I treat my 30 yr mortgage like a low interest loan. I basically take the risk that the mortgage lender doesn't want.
If I pay off my mortgage I can afford to take on more risk in the market. I can afford to attempt entrepreneurship.
It took me a long time to get to the point where I truly believed it was worth attacking my mortgage.
I prefer to have as little debt as possible for my own peace.
It's possible for me to get totally debt free in a year or two. Then I can focus on building a portfolio for retirement.
I'm also choosing to remain in my first house and not spend lots on my standard of living.
