It benefits ME as much as them.

They had explained that one member of the family had a diagnosed condition which would benefit from a service dog (sorry to be vague, but I'm not sure if saying the actual diagnosis is illegal).  

Post back, you will like the results, and others will benefit from this knowledge. :)

Our business model is to become the bank and hold paper -- not own assets and essentially become glorified landlords with a borrower who may or may not pay off the contract while in the meantime who may or may not create more liabilities for myself or my companies. 

I would say you are in a good position to benefit.

What would you think about one of the cheaper ones as essentially my start up/learning curve house.  

there by just raising rents even higher and making things worse.. those that can afford houses and have credit will buy instead of risking continual rent increases this will be a benefit to those that build homes or flip homes. 

Not so important for an opportunity zone although there are some tax deferral benefits available with those.The only advantage I can easily see is that the LLC itself has value. 

We in Phoenix, on the other hand, are greatly benefiting from people running from CA, another great socialist state :)

I get the buyers motives and benefits.
