My question involves real estate located in the State of: South Carolina and Maryland

I sold my home in South Carolina two months into a 6 month TDY (Short term assignment in Maryland). Before sale, I was having all mail forwarded to the place that I am staying in MD. Now that I don't have a permanent residence in SC, what can I do to avoid having to change all my tags, Drivers License, and stuff like that to Maryland since I am going back to SC in less than 4 months? Also, is there anything I am not thinking about that I ought to be? Thanks.
