SC property tax strategy for out of state investor

[Jack Brethauer]

Hi folks -  South Carolina (Greenville, Spartanburg, Columbia, etc) looks like a great market for buy-and-hold rentals but the property taxes are prohibitive for out of state investors.   By my research about 6% of assessed value for out of state investors, but <1% for in state.  

- Can anyone correct me if this is incorrect? 

- Are there any viable work-arounds? such as forming an LLC with an in-state partner, forming a single member LLC in SC, etc.

- How would this apply to general investing and investing via a self-directed IRA (SDIRA) LLC with checkbook control?

- Any other tips that might make this market more accessible? 

Thanks!
