Charleston, SC Outlook?

[Mike Warder]

What are people's thoughts on Charleston, SC's housing, economic, and population trends (including Dorchester and Berkeley)? My wife and I are thinking of buying a third rental property in the area and want to get others' viewpoints before we start putting all of our eggs in one geographic basket. Are companies still moving operations to the area? Population growth projected to continue? Are housing price increases justified and sustainable? 

We continue to be optimistic based on the info we have. That said, I don't want to cherry pick all the positive info without probing any negative trends people aren't talking about.
