If you happen to live in an area where home and property values have recently skyrocketed, you may also need to check to see if you qualify for any kind of income based tax relief. As the rich outsiders keep coming in and building mega mansions, all the "locals" in my area seem to be qualifying for it, even those I know have fairly substantial incomes, so it appears that your income doesn't have to be terribly low for you to qualify. But when you go in, and do try to deal with the assessors, as has been suggested, some sort of value proofs and documentations are going to work much better than "I know what you people are up to!" These people are quite used to being yelled at and threatened and they will be much more inclined to try to help you if you present them with a situation and go for the sympathy vote.
