Eviction with an out of country landlord.

[Julia Shevchenko]

hello community, I hope I can get some help here for my friend. She is living out of the country and bought a rental with inherited tenants in California, oh and doesn't have a property management co. Now the tenants are not paying rent and ignoring notices. What are her options?  Is cash for keys possible in this situation? Does any company or person could represent her in this matter in dealing with the tenants? TIA
