The taxpayer must give evidence to show that the assessment is incorrect. The Board of Review needs good reasons to alter an assessment. It is imperative to be able to answer the questions
What do you think your property is worth? and
What are you basing that opinion on?
All assessments are to be based on the sales of similar properties. You may hire a professional appraiser, or you can look at sales in your neighborhood and compare them to your home. Most assessors' offices will give you sales information. But remember this is your appeal, and the paperwork should be done by you.
