Let me know.
But that won't help you. For an appeal, you don't compare taxes. You compare the assessed value of your home to other comparables--homes near you that are similar that have recently sold. You basically say to the tax assessor: "You overvalued my home. Here are comparables. The comparables sold for less. Therefore, my home is worth less than your assessment of it."
If you make a persuasive argument, your assessment will be lowered. That, in turn, will lower your taxes.
Your tax assessor's office should have the specific appeals process online. In addition, there's usually a sheet enclosed with the tax assessment you receive that explains the process.
Hope that helps.
