buying homes in "bad" neighborhoods to rent

[Kellen Bradford]

I see a lot of homes in my city in lower income neighborhoods. 25k-40k homes. I could see myself purchasing 3 homes at least and renting out for $650 each to give me a $1950/month income . Sounds GREAT to me but scared of the idea of running into trouble with tenants in that area. Any advice on how to handle it? 

Or I can buy 2 homes in somewhat better neighborhoods and rent for $750 a month and take the lower income
