How to pick a market for our first rental property?

[Shruti Jain]

We're looking to diversify and start investing in rental properties. So far, I've shortlisted these markets but not sure how to pick one from the below selection:

1. Atlanta 

2. Austin

3. Charlotte

4. Reno/sparks

5. Dallas

Are there any other I should be considering? What are the factors I should keep in mind to make the selection? And, finally Once I identify a market, what should be my approach? Should I look for agents, property investment firms etc.?

Any advice would be greatly appreciated. Thanks!
