You received a recent notice of a new property assessment from the DeKalb County Tax Assessor and you didn't like what you saw when you opened the envelope. Maybe it was a figure that you felt was far too high, or perhaps it was the opposite and ended up too low for your liking. Either way, you automatically wondered if there were any way to ask the DeKalb County Tax Assessor for a new or revaluation on the residential or commercial property.
