To be honest, it would make me feel a sense of justice to go after her, considering her conduct from the start. 

@Mindy Jensen Cash for keys makes me feel like a loser and that there is no justice, but it isn't to make me feel better, its to save money!

In my experience in Eviction Hearings In Austin Texas, the Justice of the Peace (Judge) will NOT allow you to collect Late Fees as part of any Judgement Claim.

However in a Texas landlord -tenant dispute involving less than $10000 in damages it makes no sense to pursue with any other avenue than through the Justice of the Peace(Small Claims) Court for the following reasons :-Costs- No lawyers allowed and the cost including the Abstract in less than $200.  

The guidance also describes the Department of Justice’s revised definition of “service animal” under the ADA, as well as housing providers’ obligations when multiple nondiscrimination laws apply.The Americans with Disabilities Act requires equal access for people with disabilities using trained service dogs in public accommodations and government facilities.

Unlike tenant eviction which is handled at the District Justice level and is easy to do yourself without an attorney, Ejectments must be done in the Court of Common Pleas, and while you CAN do it yourself, in almost all cases you will need an attorney.If they are the former owners or a tenant with a lease, then they are not trespassers, and their removal is not a criminal matter but a civil matter that will not be helped by you calling the police or filing a police report. 

Circuit Court of Appeals in S.F. banned the Justice Department from prosecuting MMJ cases if no state laws were broken.

Remember the tenant can file a complaint with Dept of Justice and then you will be in court. 

If you did a good job on it, make sure you get a nice picture that does it justice, especially if you rehabbed it.
