How feasible would it be to suggest that retirees with paid off property be property tax exempt?

Some states, not all, have a homestead exemption act. it allows seniors, age 65 and older or disabled persons to receive a certain percentage of relief from their property taxes. all states are different. it is usually based on income and value of your home. I believe you can google homestead act and it will take you to a web page that will allow you to find out if your state has that exemption.
