I can't let emotion cloud my good judgement.I've severely truncated my story, as I am more interested in listening than talking, so please what Landlord behaviors do you find to be deal-breakers, and what ones do you just shrug off?

They had jobs that would cover the rent, no other 'bad' behaviors, ie. history of eviction (HATE that), and since lots of people told them no before they got to us, tended to be appreciative, high quality tenants.

We have no affiliation with PetScreening.com, but we do use their services and are generally very happy with the process.For pets, they collect photographs of the pet, as well as information on vaccination records and behavioral/bite history.For service animals, they verify the prescription with the healthcare provider.If nothing else, we can genuinely state (and document) that all applicants/tenants with pets, service animals, and/or emotional support animals are screened the same way and treated exactly the same based on a standardized set of industry-accepted criteria.

Just do your due diligence compulsively, triple-check, and ask questions.

Service dogs are not really the type to have such behavioral issues.And to clarify, the dog attacked another DOG, not the neighbor.

So as long as that tenant's behavior doesn't effect the landlord's income, the landlord is likely not to care. 

BBB is certainly not the only corporate charlatan around, but my personality allows for zero tolerance of this behavior.

Is there some specific behavior or practice of a cotenant you can identify or some aspect of the building...

Then there is the thought some would have about liability to the LL beyond insurance with the injury risks to kids involved, rowdy behavior, etc..
