like @John Umphress stated, you may be able to extract a list of charities that help paying the rent. 

Personally, I suspect the time to invest in multi family is behind us for now (wait till next recession) 5 or 6 % cap rates and you have work to do and taxes to pay doesn't sound that interesting when I can get near 5% yields on high yield muni bonds-no taxes and no work.Consider Kitsap county/Bremerton/port orchard for better deals though even there prices have increased meaningfully.

Having them participate in any meaningful way without experience seems disastrous to me so I would want them in the deal in name only. 

What should I be asking to extract all of the pertinent information that will determine if it is actually a deal?

But it is not accurate so I would not even think it is meaningful. 

Sounds like you're on the right track for educating yourself and taking meaningful action.
