@George P.who is responsible if the tenants does not pay Phone Bill and Child Support...Also based on your reasoning, they should go after the Bank as well....  

They support your accounting and work right upfront with you.

I Subscribe for PRO membership to have full access to all the knowledge and people on BP and support this wonderful innovation!

Not sure where the line between "emotional support animal" and "service dog" is, or even if it matters in this case

The only service I know that does this is called Universal Credit Service, however, they require that I have my own office space, and that I do volume with them.  

Then right after you get that going, are you starting a BP Addicts Support Group?

do the numbers support it?

If things are unraveling for them, I would call their emergency contact and get their support system involved. 

No matter how much screening you do or rules you have in the rental agreement, your tenants can be a contributing factor.I'd rather improve a neighborhood with involved citizens, grant money, the support of the city, and relationships with other landlords than have it legislated.

If you can be crystal clear and provide examples, then you're more likely to get some support from the agents.
