Inherited tenants damage responsibility

[Alisa SantaAna]

I have an inherited tenant who believes if things were damaged or missing at the time of my purchase, that they are absolved of responsibility for cost of repairs. 
The original lease states tenants responsibility for all repair costs and that the landlord is not responsible to fix damage caused by negligence. 

Of course the original walk-thru document was not given, nor photos. But the lease states everything was in working order and followed all health and safety codes. 

It’s my understanding they would still be liable but with no visual proof I fear my tenant is a professional BSer because she is now trying to force me as the new buyer to fix all of the damage caused. She got the city involved and gave them a long list of damages she expects to be fixed. 

She is also month-to-month and there are other adults and animals living their not on the lease. Which is grounds for eviction in itself. 

I’m worried she will scream retaliation when she gets her non-renewal notice at the end of the month.. Help!

At this point I just want her out so I can gut it and find a normal tenant.
