Purchasing a Condo with Month to Month Tenant in place

[Tim B.]

I am considering making an offer on a Condo here in LA. Contract price would be below market, and I am considering this as a flip. The condo currently has a tenant that has been there for 8 years and is month to month. Owner says they pay on time but for whatever reason he does not want to evict them before the sale so it will convey with tenant. So I will need to serve them a 30-day notice after I close escrow. Has anyone been in this situation? Anything I should be particularly concerned about, especially given the Covid eviction moratorium? Wondering is this is a pretty standard procedure or if I should consult with a real estate attorney beforehand.
