It all depends on your mortgage rate and the returns you are getting on your other investments.
If you have a low mortgage rate and are earning more on your investments elsewhere, do not accelerate mortgage payments.
If you have a high mortgage rate and low returns elsewhere, then yes make the additional payments.
You have to look at the opportunity cost of your money.
The other factor is how much you have saved for the inevitable rainy day. Be sure to fund your emergency savings first. You never know when you are going to get laid off. A very conservative strategy is to have six months of savings in the bank or liquid investments. That is very hard to do, but it’s the first place you should park your money before making an extra payment on your mortgage.
I don’t know about about anyone else, but I was ale to pay off my mortgage a few years early by cashing in some long held life insurance policies. As far as keeping the policies & just paying extra on the principal, it sounds good, but only if you have the money to do this. Sometimes there is nothing left of your check to do this. That should be easy enough to understand, but apparently it is not. Being paid on commission, my check would vary from month to month. You can’t really figure a budget when you have to deal with something like that.
