So we want to Verify -- is there really a double-digit increase in average property valuations in the county, and are they out of step with real values in the market?

Here's the last decade of changes to Fulton County's total property valuation.

Year after year during the recession, the average valuation dropped, 6 percent lower in 2010, another 4 percent drop in 2011, and 5 percent down in 2012.

They didn't start inching up again until 2014.

A 17 percent jump in total assessments from last year -- verified as the single highest property assessment increase in a decade.

The county's valuations are 33 percent higher than they were in 2014.

But is that out of step with the market? Our analysis shows Fulton County homes in the aggregate are selling at or above the average tax valuation.

But with no increase in tax rates at all, the average property owner in Fulton County will still see a 16.5 percent jump in their tax bill because of these valuations.

So it is VERIFIED -- a double-digit increase in the average property valuation.

But your actual property values have grown, and these assessments are not wildly out of step with the market on the whole.

The average homeowner will see a huge tax increase unless they file an appeal, or convince the county commission, cities and schools to lower their millage rates.
