In 2008, the county raised my property taxes an exorbitant amount, so I made an appeal to lower them. I looked at the houses that had been sold within a five-mile radius and the home values were not supporting the tax assessment, so I did a first-level appeal with the tax assessor in my area. I showed her the hard data and she realized that my home had been over-assessed. Through presenting facts, I was able to lower the assessment by $60,000, a nearly 20% decrease. That saves $237 a year.
