Next door neighbor passed away from ALS. Her husband a 100% disabled, retired Marine. In return for in home care they had to sign over their mortgage free home to the state of PA. He can live there until he dies then it goes to the state.
Considering what home care costs, it's probably a good deal.
My proposal for older people on fixed income who can not afford to pay their property taxes is just to leave them alone and place a lien on the property. It will eventually be sold and the government can collect their money then. But there is no reason to throw those older people who have paid their taxes for generation out at this point.
Leave them alone to live out their days.
