Property Tax in South Carolina

[Jake Caster]

Hello ~ I am looking at properties in South Carolina (north Augusta specifically) and would like to make sure I understand the property tax rate. From what I read, for rental properties the annual tax is 6% of the appraised value multiplied by a millage. Overall it works out to about 0.5% of the property value.  I've bought several properties through Roofstock and often use them to evaluate properties.  Their pro-forma statements for SC properties has the rate at almost 2%.  I've found errors on their pages before, but if it is an error, I haven't come across one so widespread. 

Any insight would be appreciated!
