Rental Investment Property - GA vs TX vs ID

[Ashley Rodgers]

I'm evaluating on buying 1-2 rental properties (either SFH, Duplex or Triple) planning to hold for long term and looking for some decent positive cash flow.

 After my extensive research, I short listed four state GA, TX, IN & ID.  I was looking for some suggestion or opinion to narrow down my search.  

Which cities from these four I should pick - Atlanta, GA , Fort Worth TX, Indianapolis, IN or 

Boise, Idaho. 

Thanks in advance!
