FAQs for How Reappraisals Affect Your Property Taxes

Why is this important for Property Owners to Know?

Short answer is that it will affect the value of your property for real estate tax purposes and a possible increase in you bi annual property taxes you pay.

What is a Triennial Update?

A Triennial update is a review of valid sales over the period of 3 years, since the last appraisal. The sales data is looked at for trends in the market and values are equalized based on sales factors specific to each neighborhood. Therefore, changes in value will vary between neighborhoods. Neighborhood areas for valuing purposes are defined by like housing, type, age and size. As the name indicates, this is designed to update market values and therefore update assessed values of properties to tax purposes. Triennials occur 3 years after the last Sexennial.

What is a Sexennial Reappraisal?

Under Ohio law, County Auditors are required to do a full, general countywide reappraisal once every 6 years. The Auditor or his/her qualified appraisers are required to view and appraise every property in the county for this purpose. The process takes between 2 -3 years to complete. Reappraisals can be in the form of an actual appraiser visiting the property, however it also includes “drive bys” of properties as well.

What is Market Value?

Ohio’s constitution, laws and courts have determined that the measure to be used determining the value by which property is subject to taxation is the “estimated fair market value”. Market value is defined as the price your property, would likely sell for in the market.

What Causes Changes in Valuation?

A primary objection of a revaluation is to adjust and equalize property values to reflect changes in the marketplace since the last valuation (Sexennial) . Since property values do not change uniformly, some values will go up, some stay the same and some will have gone down since the last valuation. Other facts, beyond variations in market value may cause a change in valuation. These could be alterations or change in the property, such as new construction not previously reported, new siding, buildings added or removed, interior finish added to basement or garage, new pole buildings constructed etc. A change in property use might also dictate a change in valuation, for example, a property use change from residential to commercial.

How does the county determine the value for a property?

For the Triennial, they appraise properties utilizing mass appraisal methods using a hired contractor that specializes in mass appraisals. The contractor will complete a reappraisal of all properties by gathering data on every property in the county and building tables that will determine the value. The accuracy of these tables is tested by looking at sales that actually occur to determine if the tables need adjusted.

If I disagree with my property valuation what can I do?
