Drive towards a solution where you and the tenant come to an agreement and try to remember that he's human...driven by emotional reason. 

Because the service animal is not actually living with the person who it is intended for, I was making my comments under the assumption this was more likely a "emotional support animal."

You can't become emotionally attached to anything in this business because that's when you lose out on opportunity and money.

As a purpose built rental the price is generally driven by the rental income not the emotions of buyers.Pull your home equity to invest but do not expect to be reliant on the income when you are unemployed in 4 years.

Sellers and seller's agents (if it is listed) become emotionally attached to the list price far too often. 

Does anyone know if Emotional Support Dogs, with all their paperwork (whatever that means) are a protected class? 

Don’t get emotionally involved and be willing to live in high ARV potential home so your profits allow you to live wherever you’d like!!

I’m clearly emotionally attached to this property but I feel like it’s gonna be a gold mine when the new development up the street is finished. 

Ignore those emotions.

They are in pain and will make their decision based on emotion.
