I successfully appealed and won multiple times. My best advise is when you go meet with the assessor, you need to come in with evidence to support your suggested value. In each instance, they asked me what I thought it was worth. By evidence, I mean assessed values of comparable homes, recent sale prices of comparable homes, comparable homes currently on the market for your target value. Everyone has heard “location location location” so the comparable homes need to be in your area. Print off your evidence and bring it with you and as long as your evidence is solid and your suggested value is reasonable I suspect you will win.
