State law puts the burden of proof on the property owner to show that the assessment is incorrect. Keep in mind that your evidence must be strong enough to prove that the assessor's value is incorrect. Only relevant testimony given at the hearing will be considered by the Board. STATING THAT PROPERTY TAXES ARE TOO HIGH IS NOT RELEVANT TESTIMONY. You should establish in your own mind what you think your property is worth. The best evidence for this would be recent sales prices for properties similar to yours. The closer in proximity and similarity, the better the evidence. Another type of evidence is oral testimony from a witness who has made a recent appraisal of your property.
