How do you appeal property taxes?

The process of filing the appeal will vary from county to county. I would say start by reviewing your assessment notice to first ensure that all the data is correct. Next, I would look to see if you can find recently sold real estate comps in your area, meaning comparable homes to the one that you're in that will give you a comparative value. If you find that homes that are comparable to yours are assessed for much less, you may have grounds for challenging your assessment based on the fact that it's not consistent with the way that the other homes were assessed.
