By May 1st, 2017 you should have in your possession a new Notice of Valuation (NOV) of your real property value as assigned by the assessor, and based on comparable sales. Average Summit County increases are (anecdotally, not scientifically- yours can certainly divert in either direction from here) 15-20%. You have until June 1st , 2017 to postmark your new value should you feel its unfair. Your evidence must be supported sales that you feel are a better comparison to your home than the ones used to create your new valuation.
