Tax rate in Dekalb County, GA

Hi,

I'm trying to figure out what the property tax rate is supposed to be for an out-of-state investor. I own a SFR in the city of Decatur in Dekalb county, GA. From reading online the rate is supposed to be like 1.2% (which was indicated on the MLS sheet). However I understand that investors don't get the Homestead exemption. That said I'm not sure if 1.2% if supposed to be the "official" tax rate from which the onto which the Homestead exemption is applied (meaning homeowners would pay LESS than that) or if that's the rate already with the exemption factored in, in which case I would be paying significantly more than that.

Thanks,
Olivier
