• Cost Approach - First, the value of the land is estimated, as if vacant. The assessor then adds the amount it would take to replace your structure with 1 of the similar utility, including current costs of materials and labor, profit, overhead, permit fees, and the like. If your structure is not new, the assessor then approximates depreciation from all causes, and subtracts that from the calculation of replacement cost.
• Market (sales comparison) Approach - Your property is evaluated based on comparable properties that have recently sold, and is adjusted for differences such as a garage, finished basement, or better location. Where there are frequent sales and similarities in properties, this can be the most reliable approach for residential property.
• Income Approach - This approach works well for apartments, shopping centers and office buildings. The assessor estimates potential gross income from rentals, then subtracts an amount for vacancies and operating expenses. The amount of net income is then converted to a value for the property, using a process called capitalization.

If you do not agree with your assessment, there are 3 steps you can take in the appeal process. Remember that an assessment is based on current market value and our objective here is to establish the correct market value of the property. Stating that property taxes are too high is not relevant testimony. You should determine what you believe to be the value of your property and gather and present evidence that supports that value. Such evidence could include photographs, the recent sale of your property, or the oral testimony of someone who has done a recent appraisal of your property.
