> There can be provisions to ensure that people don't lose their homes to rising property taxes...Texas, IIRC, has one that allows property taxes to accrue and only need to be paid when the title of the property changes hands, which seems like a good compromise.

So it's not OK for rising rents to force property elderly owners to sell and move away, but it is OK for rising rents to force elderly renters to move away?

You can't defend property tax deferments for the elderly without also defending rent control for them. Either way you have the same problem of local residents thinking it's OK for everyone else to suffer lower supply and higher costs, as long as they aren't suffering.
