Bowhunter12,
I understand your frustration. I was a county assessor for 3 years and been on both side of this (assessing property taxes and paying property taxes). The increase on your property sucks no matter what. However IMHO You need to ask yourself one of two thing: Are you mad with your value or are you mad that yours assessment isn't fair and equitable? If its the value, was there ever a assessor who entered the home? if not request a reassessment on your property, happens all the time, maybe they thought it was nicer inside than it really was. If your mad because you think your unfairly assessed compairitivly to your peers for some reason, then thats a bigger problem and one typical of township assessors unfortunatly. Being "equitable" is the name of the game in assessing, doesnt matter if everyones high (110%) or everyones low (80%), everyone should be the same in regards to assessed value in relation to what market value is. Either way if your looking to win an assessment arguement, it isnt going to be getting mad about the increase (you very well could have been under assessed for years and paying an unproprtionate share of your property tax burden because of it). Its either going to be with the value or unequitable assessments. I would encourage you to make an appointment with your County's Tax Director (Amber G.?) and discuss your concerns with supporting documentation to further your concerns.
