Mr Reid,
I live in Lexington and work in Columbia (and my parents were both OSU professors and lived in Columbus). I can answer some questions about the area if you'd like to e-mail or PM me.
I tend to think things here are about like they are in these sorts of secondary markets: lots of demand for flip properties, wholesalers who pop up with a good one now and then but it isn't easy. Actually, it is very easy to buy flips, much harder to find profitable ones and reliable contractors. But we do it every day.
There are parts of Columbia that are the equivalent of the Short North in Columbus the way it was 20 years ago: gentrification, rehabs working their way through entire neighborhoods. I feel sure the cost-to-play here is less than it is in Columbus although maybe Canal Winchester is lower-priced than Arlington, Bexley or Westerville.
Holler if you have specific questions and I will help you connect with people that can answer those intelligently.
Regards,
Christopher Bunge
