They like to see at least $100/unit minimum, and would prefer to see closer to $200/unit if possible when they do this quick litmus test of whether something is a good deal or not.With your numbers above it would seem that taking the 50% of your $319 and then dividing it by the three units, you'd end up with about $53/unit/month in cash flow.  

Do some A/B testing with the approach and let me know how it goes! 

It will be critical to try and pass your test on 1st attempt because the certificate will the be good for 6 years verses 3.IMPORTANT,,,all certificates expire at deed transfer and the new owner has NO GUARATEE of future passing.

(I'm planning on using hard money+my HELOC to Buy, Rehab, Rent, Refinance, Repeat..)He won't pass any tenant screening tests, that's for sure, but I feel like I could probably structure a deal that gives him enough cash at closing to put 12 months of rent into escrow up front.
