I'd simply present the facts plainly without emotion to the owner and ask politely to be reimbursed.

I got the sense that he has an ethic of service and is out to make a contribution, also as someone with military background (discipline) and active faith (trustworthiness).

It takes 5 years to get good at any discipline.  

The problem isn't lack of opportunities, especially in the USA - it's lack of discipline, willpower, and the ability to postpone gratification that is the problem.

(There is a $7K balance on a property worth prob $150K)So the lady who has had the property is a bit 'emotional.'

A divorce after years of marriage with kids, is an expensive and emotional experience. 

Rarity is the amount of emotion that people get when they see your post.

Established PM's don't like to go into D areas: it's a lot more work and emotionally harder on their staff for the same percentage - but of a lower rent. 

A landlord does not need to provide a reasonable accommodation for an emotional support animal when:The property is an owner-occupied building with four or fewer unitsThe property is a single-family home sold or rented by the owner without the use of an agentThe emotional support animal poses a risk to the health or safety of other people, or a risk of substantial damage to property (but this risk must be specific to the animal and cannot be based solely on assumptions about the animal’s breed)"Definitely have a chat with a local attorney to ensure your local laws apply, nonetheless since its an owner occupant, it sounds like you have some recourse to deny this request. 

Now we’re not all Warren Buffets, but I also take him at his word that he and Charlie Munger are not actual geniuses either - it’s mostly knowledge, discipline, and patience.
