You never really “own” your home. You are just renting it from the government. They call the rent “property tax” but failure to pay will get you evicted the same if you were not paying on a rental unit.
The only difference is you get to pay all the insurance and maintenance cost of this “rental”.
Having said that, I think it is still a wise decision to pay off your mortgage.
My property tax is around $110 a month. Less than the cheapest apartment and as long as I can scrape up the money for the taxes each year, I have a place to live.
I believe that we should exempt food and shelter from all taxation.
