Property tax is a very poor and inequitable method of obtaining revenue for government, because it assumes that the mere ownership of property suggests the ability to pay. It is quite common for a person, or family to spend their working days building a nice home and property, only to have to sell it in their retirement years, because their retirement income doesn't allow the wherewithal to pay the taxes on the place.
In my state, some relief is allowed if your retirement income is very, very low, but even then, the state gets it back when the estate is settled.
