Not At Fault Tenant Eviction

[Bryce Travis]

Hey all. I'm venturing into new territory here and looking into tenant eviction for a property I will be putting an offer on. 

The property is a multi unit with a tenant in the back who has been there for 15 years. I've done some research into 'not at fault' evictions, and it seems like I could pay the tenant a 10k relocation fee if i plan to use the space for myself or a family member...

Does anyone in the Los angeles area have experience with this? What are the potential pitfalls to watch out for? How long does this process realistically take? 

Thank guys! Appreciate the guidance!
