Out-of-State City Information

[Juan Mendoza]

Hello everyone, I'm from California, and I want to buy either a single-family or a multi-family home out-of-state for cash flow.

Can someone tell me what I should know about an out-of-state city before I decide to buy property there? Also, how would I obtain that information? I'm assuming it's good to know the unemployment rate in some areas, so how would I obtain a credible source that can provide me with that information? 

Thank you!
