How does the Assessor's Office determine the value of your property?

With Notices of Value coming out June 20 in Chelan County, Chief Deputy Assessor Erin Fonville gives us a quick education in how the Chelan County Assessor's Office assesses your property. She explains the difference between her office and the Treasurer's Office and the difference between your notice of value and your property tax notification. She even talks about what to do if you don't agree with that Notice of Value. These are heavy topics -- that we know you want to know more about! Erin does a great job of explaining how property assessments work. So listen in to our county webcast and make a Chelan County Connection!
