New to Real Estate Investing

[Sean Hoagland]

Hi Everyone! Love the community here. I currently have one single family rental in Saint Petersburg, FL. I just moved to Chattanooga TN and I am looking to start investing in some cheaper rehab homes that can be used to rent. Is Chatt a good place to do this? Should I be looking in neighboring cities? I am also wondering if it's best to use cash when buying and renovating these properties? 

What do you all think?
