You also need to consider the legalities of tenants with service and emotional support animals.

A friend of mine living in Utah is trying to get an emotional support animal, but her landlord is having issues.

Just another example of how the Emotional Support Animals are an example of people abusing the system.American Airlines passengers’ shock as traveller takes miniature HORSE onto flight. https://tiny.iavian.net/uucl

The moment that you let your feelings and emotions effect your business decisions, its probably time to hire a property manager.

In the state of CO can you delineate a maximum number of emotional support animals allowed per residence within the leased property? 

I suggest that you practice running numbers on a handful of houses that you have no intention of buying ( it takes the emotion out of it) - get proficient at ARV and repairs, those are the two places people get hurt in this business and oddly enough the two numbers that as investors we are so willing to trust and not verify. 

I asked my lawyer about service and emotional support animals.

Then I came to understand that most people don't really care that they've been caught and exposed as half-a-human-being unless you rub their faces in it and humiliate them with the stupidity of their lie, over and over again.I also learned that most long-term renters are only really capable of feeling two basic emotions toward their landlords: dread and contempt.

Now they are claiming it is an emotional support animal.

The 2 people apparently both have emotional support animal paperwork that had never been disclosed to me during the rental process.
