If they are borderline we keep them in a holding pattern and keep scoring/investigating others.No matter how you do it, you need a consistent approach and criteria that is defendable and non discriminatory.Sounds like a good problem to have!

I write a tough email to other tenants defending this kid and telling them no smoking AT ALL in house.

She called a lawyer and he tried to defend her, but I cited the law and the lawyer responded with "My client will abide by the terms of the rental agreement and vacate by the end of the month". 

I had a judge tell me he has only seen one time in eviction court in 10 years that a tenant gave proper written notice for a repair request.Remember at least in my area the landlord and tenant or plaintiff and defendant has to pledge under oath and penalty of perjury that what they are saying and information provided is true and correct.

Actually, you can file it in any county if you think they have moved to a different oneSuing for Damages and Late Fees Etc- This is a separate suit that will need to be filed and the cost to do in small claims court for amounts up to $10,000 is aprox $175 for 2 defendants. 

Long story short, after talking to the Mgmt company and their attorney the case was pulled at the courthouse and an entry was made in the record to strike my name as a defendant.

We all know someone with a car that lives at the shop, is a legally verifiable lemon, but they defend it to death.

Through a very good lawyer we have started the eviction process and filed counterclaims for legal fees and back rent as well as a cross claim demanding the previous owner defend our interest since we were issued a general warranty deed.

Don't think that a savy ACLU or ADA lawyer wouldn't leverage HIPPA to defend a person's right to not be forced to disclose protected healthcare information to satisfy a landlord's issues with "pets".  

Owners can find themselves having to defend themselves from a very costly lawsuit which could go on for a year or more, all because they left items behind for the tenants to use.
