New landlord facing first eviction. Any advice?

[Chad Gaither]

Thanks to this amazing forum, real estate networking, and some hard work I closed on my first triplex in Long Beach, CA in December. As part of the contract, the seller's agreed to give 30-day notice (it's allowed in the area even though she's been there for 7 years or so) to one of the tenants so we can house hack. We've met with the tenant numerous times and have offered help through sending her listings and have offered cash for keys. She has paid rent for this month but we've let her know that we cannot have her stay in the unit for the next month as we need to move in. We haven't seen any progress (or packing) and now the 30-day notice has lapsed. We've told her that we'll give her until next week to find a place or we'll have to start the eviction process and she did not seem worried (which worries me). I've talked to a lawyer and we are ready to start the eviction next week. Any advice on trying to avoid the eviction or any advice for the eviction itself would be greatly appreciated!
