Just over 9% of the population have a diagnosible personality disorder and many more, while not disordered to the point of a diagnosis, are just "difficult" people-- they have "entitlement issues" they will always be disappointed because no one ever gives them the respect they think they are due.

The apartment falling into disrepair is one thing, but hoarding is now recognized as a mental disorder and you don't want to be accused of discrimination.  

@Joe Gore Banks are changing policy so often I'm starting to think they are all Bipolar.

However, you do need to be aware if one of these tenants is unreasonable-- as this kind of unreasonableness is often the sign of some type of disorder.

Sister 1 says that Sister 2 is bi-polar and won't move out and she has the car and Sister 1 doesn't have a car and there's nothing she can do.  

After she signed the contract and gave me the check she proceeded to tell me she has a bi polar daughter who got out of jail recently and it’s trying to get her to move in.

Brandon Sounds like she may be bipolar or schizophrenic with all the back and forth.
