Similarly, I'm not too sympathetic to those (often elderly) who claim they can no longer pay taxes due to fixed incomes while home prices increase. The amount their taxes have increased are a fraction of the equity they've gained - they should be able to obtain some sort of "reverse mortgage" that pays the taxes in exchange for partial ownership of the home, which would then be settled at time of death by the heirs who'd just not inherit the home 100% clear.
What does bother me about ever increasing property taxes is the entitlement of the localities and states on that increased revenue without justification for the improved services they'll provide to taxpayers in exchange. In a city like Austin where home prices have increased close to 50% in just the last two years, that must mean the city and county's gross tax revenue has also increased by some proportion of that.
I think most states and localities should be forced to run like a typical well run HOA where all costs and planned expenditures are 100% transparent. Taxes should only rise on properties when there is a justified cost increase, and should not automatically go up when values do.
