Charleston Duplex Taxes

[Patrick Bross]

Hey all,

Question on how Charleston, SC handles taxes on a duplex. I own a downtown Charleston duplex and reside in one of the units (primary residence). I recently submitted my residency application to retain the more favorable tax treatment but was only granted 50% at the lower rate, and the other 50% at 6%. Is this normal or should I get a break on the entire thing? I ask because my mortgage is escrowed to pay taxes on the rate at which the entire property would be considered primary. 

Any help is much appreciated. Thank you!
