I know very little, but I can say that the question on "average cost per acre" is one of those questions that will generate about 200 more questions that you'll need to answer before you can get an answer to your question.
Being that you are looking in the Carolinas, what land goes for in Texas pretty much has no bearing on where you are looking.
Same with maintenance costs - there are literally thousands of factors that can go in to making that determination. Terrain, geographical features, indigenous wildlife, cows, invasive species, type of trees and grass, etc. all play big roles into what constitutes a maintenance cost.
