People will pay extra in order to have their fur babies with them. 

They must have utilities in their name before I will give them the keys.I generally give them the keys on the day the lease starts or the night before if my baby has a dr appointment in the morning of the day the lease starts.

This post reminds me of a situation like you see a baby laying on the train tracks.

You could also add like a mini garden or flowers along the house or side walk leading up to it.

I’ll keep my eyes out for a mini storage purchase.

Maybe a mini Schnauzer, Poodle, Spaniel etc?

That is a way more affordable option than updating the duct systems or adding mini-ductless splits.

I have a heat pump mini split in my ADU in Dallas, works great. 

If possible find a cheap grandpa car or truck, they are usually babied and meticulously maintained. 

They just put a sidecar on their motorcycle for the baby, and continued their trip for the next year hahahaha Nothing can stop you if you are determined!!!
