If the 5 days has expired and still no rent payment, then file the UD (unlawful detainer)  with the court or with your attorney.

If I were you I'd listen to the others, but this seems a good place to share my working solution for my situation, because it might help someone else wondering about this.One of the things that small urban landlords are sadly known for is using their own set of keys to enter the premises unlawfully while the tenant is away.

Note: If a county recorder, title insurance company, escrow company, real estate broker, real estate agent or association provides a copy of a declaration, governing document or deed to any person, California law requires that the document provided shall include a statement regarding any unlawful restrictions.

Also conduct an eviction search to make sure she was never even named in an unlawful detainer action (I don't allow any prior evictions, ever). 

If the tenant does not comply, it is the landlord’s prerogative to file an unlawful detainer or not.

If no one responds within a reasonable time, file an unlawful retainer.

It is unlawful for any person to engage in the business, actin the capacity of, advertise or assume to act as a real estatebroker or a real estate salesman within this state without firstobtaining a real estate license from the department.

My agent sent her a pretty strongly worded email asking for an explanation for the unlawful intrusion and licensing violation of giving out her key code.Her response was that she checked her logs and claims that she was there with the clients herself and that's she's very sorry for not having made an appointment and she's very sorry for that and "what can I do to help to ease the pain?"

If the former owner after foreclosure doesn't vacate after the 3-day quit notice, you go to an unlawful detainer.  

The case is beyound just churning, from failure to give notice, unlawful entry, theft and wrongful sale...anyway, that's something else.If anyone needs assistance or wants some infromation of L/O, installment contracts or seller financed, feel free to contact me, it free!
