This is beyond unreasonable behavior. 

Did the tenant display disruptive behavior?

I would suggest looking for a PM that has those kinds of characteristics and behaviors.

There has been no behavior problem either.  

Hi all, I have an ex-tenant which I evicted due to their hostile behavior which threaten other tenants.

Try to take note of who was who when they signed your list, so you can make notes about rude behavior, etc.I would not require them to turn in the application right then and there, but tell them that you will need it by (whenever you want to start processing applications).Then, when you are ready to start processing the applications you received, start crossing out names off the list that didn't return an application or were denied for any other reason, and make notes to that effect.Then, start doing your credit checks, etc., in order of the ones left on your list you are willing to consider.Then, when you have your short list, start calling them and asking for copies of pay stubs, etc.Then, see what you get, and start calling employers and previous landlords, and Googling them, etc.Then, make your offer to your top choice, on down, if they are no longer interested.Good luck!

Include the CCR in your lease and have the tenant sign that if fines are incured due to the tenant behavior, the tenant will be in breach of the lease.99% of the time the tenant is doing one of a few things: parking in a red zone, having loud parties, bringing to many guests to the pool, unsightly belongings visible, unsupervised pets, not leashed, defacate in the common area, unsupervised children (that make noise and break stuff), speeding in the deiveway, bringing food, glass, beer or marijuana (legal in CO but not CA) into the pool area, indecent or illegal activities in the common area.I've seen it all.

Since she is exhibiting what I would call "attacking" behavior ... this could wind up costing you lots of money if you allow this to continue.    

We'd be having a "talk" about that behavior and hopefully come to an agreement right then and there, and document said agreement. 

Live and learn.And, their ex will be around, maybe move in, move back out, screaming fights, furniture being thrown in the hall - professionals are not immune to this behavior.
