There are Many on here who will say you are loosing money paying off the mortgage, and they may be correct. But that feeling of
being debt free, of owning your own home outright and not having to pay rent either, puts you so far ahead of most people and the stress relief is worth it. I love that my expenses can be super low ( and my income also) because I have less risk in my life.
If I loose my job or take a paycut or want to take a year off I know my expenses are already low and less complicated.
For retirees it is less income that you have to take from your investments, may makes the tax time less complicated.
Just the head space it opens up is so worth it for me. Now as someone said continue to save and invest that mortgage payment!
