Lease Option Buyers - Bad Credit?

[Kelvin Letron Brantley]

I have a question regarding lease option buyers.  Once of the assumptions we make about lease option buyers is that they probably can't qualify for a bank loan.  If that's the case, what are some of the screening techniques I can use to have a warmer and fuzzier feeling that they will pay me every month.  Just because they can give me a large down payment doesn't mean they will pay me on time every month.

Thanks,
Kelvin
