If their property taxes increased to the point where they cannot afford it, then that means that their property value increased significantly. Excuse me if I don't feel too bad for somebody who just reaped a massive windfall.
The "won't somebody think of granny?" argument doesn't really work when advocating for a policy that disproportionately subsidizes non-grannies.
“Reaped a massive windfall” if and only if they sell their house. The problem is unless they’re both looking to sell and move into a lower COL area, that doesn’t do them much good.
My house today is worth 2x what I paid for it a decade ago. Which is great except for the fact that housing costs around here are closer to 3-4x what they were a decade ago. Even if I wanted to sell, I couldn’t find any livable housing for the same price within the same area.
