Real Property

Real Estate Sales Ratios, By Class of Property and by County, Calendar Year 2010

Under state law and Ohio Department of Taxation rules, real property in all counties is reappraised at 100 percent of market value every six years and updated the third year after each reappraisal.  Thirty-five percent of the market value represents the assessed or taxable valuation of real property.

In order to verify that real property is being assessed at or close to 35 percent of market value, the Department of  Taxation surveys real property transferred in each of Ohio's 88 counties. Sales ratios are calculated by dividing the total assessed (taxable) value of the transferred properties by the total consideration (sales price) paid for those properties.

The resulting ratio shows the average taxable value as a percent of the average sales price for each class of property.  The lower the ratio, the greater is the amount by which the sales price of the property exceeds its reappraised or updated value.

The attached tables show a summary of sales ratios and numbers of sales for the four classes of property: agricultural, industrial, commercial and residential. Counties were either reappraised or updated in the years 2008 through 2010. These tables do not include property transfers that would make the ratios unrepresentative of sales activity in the area.

The survey for the first six months of 2010 (I/2010):

  • Property transfers totaled 37,108, of which 35,123 or 94.7% were residential property transfers. Compared to the first half of 2009, these results represent a drop of 32.0% in total property sales. 
  • The statewide assessment ratio (for sales of all classes of property) was 33.99.

The survey for the second half of 2010 (II/2010):

  • Property transfers totaled 30,878, of which 28,437 or 92.1% were residential property transfers. Compared to the second half of 2009, these results represent a decrease of 29.6% in total property sales. 
  • The statewide assessment ratio (for sales of all classes of property) was 33.90.
