Also, with low/zero IR, PV of tax payments is infinite, it's not like increasing house price is offsetting that.
In practical terms though, property taxes aren't infinite -- they're only for as long as you're alive. And you can realize your increasing house price while you're alive too (or your kids can). And I know people who have come out very much ahead in that equation in certain gentrifying areas, e.g. turning a $30K investment in 1985 into an $8M sale in 2020.
So within reasonable "non-infinite" time frames, an increasing house price can be very, very, very much offsetting property taxes. That's just a fact.
Not really. You’re saying it is no issue that tax goes up proportionally to house value, I’m saying it is much more onerous than, say, your income tax increasing with income.
Also, if the end objective is “pay tax to local government and make it so that wealthier people pay more”, there are tons of ways of doing it without this anti-feature. Slice of income tax, tax depending on property size (not price) etc.
I say it is unjust for a fixed income senior citizen or disability insurance recipient to have their property tax base grow to a point where they must flee their home of decades. The callus answer is to force the person to sell and take their gains and move so a younger person with higher wages can afford their once-home. I think it is unjust to remove an older, less abled, and less employment-opportunitied person from their environment.
Any senior citizen who owns their home (mortgage all or mostly paid off) can take out whatever size mortgage necessary to pay property taxes. Since it's backed by the house's larger value itself.
Who's making them "flee their home"...? That would only happen if it's already mortgaged to the hilt, but then they're already on the verge of losing it anyways.
In addition, California (and I suspect other states) have a means tested property tax postponement program that allows low income homeowners to defer taxes until they move out, sell, refinance, or die as a substitute for obtaining a private loan.
If you don't have cash, take out a small mortgage on the house to pay the property taxes. You'll still come out ahead in the end.
