Hood investing war zone or close to it

So I have been looking at property's in the hood evenly and god damn they look like they cash flow really good. However I have heard to get the type of cash flow it requires a lot more work then non hood areas. These are single family homes I've only heard about hood multi what are hood single family like. sense there is high turn over would it make seens to rent by the month. Do you still evict someone if they don't leave after the lease is up or is there another way to do it. And how do I avoid getting shot if I offend or evict someone.
