One way to solve the issue of people being taxed out of their property would be to give the option to put a lien on the property if they’re earning less than a certain income (or over a certain age). This way, the owner gets to stay in their home, but the city is (eventually) getting the taxes it’s owed.

I haven’t fully thought through all the incentives it brings though. However, it seems like a better solution than telling people to reverse mortgage their houses. Especially given how predatory that industry seems to be.
