I agree with Erica. You must research you Tax Appeal carefully. It is possible to win but it is also possible to lose or you could have your taxes raised.
While it's a simple form to fill out, and try to appeal, it is NOT a given that you will win. I disagree with the pro who says you're likely to win on appeal. I headed up our county Appeals Board in the past and I can tell you that most homeowners did NOT win the appeals process. You must prove WHY they should be lower and if you pay a high price for your home, the school district will argue that you should in turn pay higher taxes. In the end, if you PAY a high price, you set the value and you are likely to lose your appeal (at least in our area of PENNA). We are just one county north of Berks.
