Deciding which market to invest in?

[Scot Poore]

Hello All! 

I am looking to buy a few buy and hold rentals in the the next 18-24 months. I am doing some research and exploring which market I should invest in.  I live in the Atlanta Metro area, but I am looking to invest in a smaller town that may have better cash flows per door.  A few markets I am thinking about are as follows. 

1. Montgomery, AL

2. Jacksonville, AL

3. Rome, Ga

4. Athens, Ga

5. Huntsville, Al

6. Douglasville, Ga 

If anyone has any insight to which markets they think have good opportunity or any other recommendations please let me know! Thank you!
