Zero criminal background.Credit score above 650 and preferably above 700.Different markets have different tolerances, and individual landlords have their own tolerances as well.

It also depends on your tolerance level, your court system, and other factors.

Seems like a bit of overkill to me, but it depends on your risk tolerance. 

Look for deals that fit your budget, criteria, and risk tolerance, and I'd say add a little more reserves for good measure.

I just want to explain from a lender's standpoint why this might be above a lender's risk tolerance, so you can possibly find another alternative.

@Luke J Nelsen You should get used to this rising rate environment and build in tolerance in your analysis.can't imagine an actual "good deal" that would become a bad deal due to a 0.5-1% rate increase.

Once you're comfortable, re-evaluate your situation, experience, and tolerance for this type of risk.

It just happens the "P" are various banks and not individuals  :)  That way I take on debt vs. giving up equity (which is a lot more tolerable IMO)

I think the most important questions is how much hands on management can you afford in these areas, and what is your risk tolerance to C,D,F neighborhoods?
