One way to contest your assessment is to use recent property sales. The Evans town wide re-assessment was in 2008. The town is assuming your property is worth more today that it was in 2008. You can look up your 2015 full value assessment on the Assessments2015 page. ( You must register to view all data)
If you live in the older Highland neighborhood or Lake Erie Beach, many properties are selling for less than their 2008 assessed value. These two neighborhoods have paid and will pay more than their fair share of taxes. You can use the sale of over assessed properties to get your assessment reduced.
