Alot of cities are cracking down on the "just cause" so if you can get them to agree to a voluntary vacancy it is much better situation and if they do not agree with that then you can evict with unlawful detainer**not legal advice just my opinion - each city and circumstance can be different

So you will follow local laws on notices ets, and eventually file for 'unlawful detainer' in court.

If he doesn't vacate, our attorney is locked and loaded to request a detainer warrant with the court.

In the end, we had no other choice but to file an unlawful detainer to get him out and get our property back. 

You'll be amazed how many people have claimed they will empty the rental only to discover they've taken a few items of value and then left you with everything else.If they haven't provided a point of contact, or if you want to confirm the point of contact, you can always visit them at the location where they are detained and ask them.

I'm sorry to hear this.Contact a local attorney who handles L/T routinely for advice and do what they say.You can likely file an Unlawful Detainer to have her removed.But you might also try contacting her Housing Authority caseworker, posting a notice & attempting to meet with her in person and being extremely empathetic about what she's going through. 

Some states require a 30 day notice, some a 60 day notice so again, follow your local laws exactly.IF.... they don't comply or move out, that's when you file an unlawful detainer (eviction) and just have to go through the process.

Unlawful Detainer?

I am the landlord and I filed an unlawful detainer.
