@Jared Cooper I recommend Barbara Habbeshaw of AZ Residential Management.

I DID tell her to honor her notice and leave but she is not being cooperative at the moment. 

If you are splitting the bill, then it needs to be in your name because you cannot expect separate tenants to cooperatively handle this.

@Charlie Cooper I would want something in the range of $100-200/per door if possible, I wasn't really targeting a specific CoC %, is there generally one that you like to aim for?

I always add some relocation or free rent to get more cooperation. 

On the other hand, if you signed an agreement and genuinely owe them the money, and an honest mistake was made at closing, you probably also signed something like an "Errors and Omissions Compliance Agreement" which states you will cooperate with the closing agent/title company to correct any errors. 

We are currently eviction tenants whom have not cooperated and do not have a declaration of hardship on file.We started this process in September when judges started taking cases.

Seller needs to agree in writing that they will cooperate, sign the forms, show up for hearings.

If this is impossible or the tenant is not cooperating then the landlord can step in. 

You will have to see if you qualify but that would probably alleviate the pressure and make your tenant more cooperative.
