Which state to purchase a Duplex in?

[Michael Hunt]

I'm a novice investor trying to get a better handle on which state to look into for a duplex investment property with a goal of cashflowing. 
I would like to invest in either the Midwest or Southeast as it is my understanding that those regions are great at cash flowing. Based on my research on landlord-favorable states, I came up with:

Midwest: Indiana and Ohio

Southeast: Arkansas, Louisiana, Alabama, Georgia, North Carolina, West Virginia

Would you not invest in any of these states, and if so, why? I was thinking of potentially ruling out Louisiana due to flood risk.

Thanks in advance!
