How do I know if my Johns Creek property taxes are too high?

Comparing your Johns Creek home's assessed value to what genuinely similar homes on your street or in your subdivision have recently sold for is the clearest way to spot an over-assessment, since property tax is billed on 40 percent of fair market value. A jump in assessed value that outpaces what comparable homes actually sold for is a signal worth investigating. Your annual assessment notice from Fulton County lists the current figure. Ask Joel to pull the comparable sales for your specific street.
