BRRRR on 4plex question

[David Thompson]

Im about to make an offer on my first 4 plex. Im planning on rehabbing the entire property. Currently 3 units are rented. What do you do about tenants during a rehab? Do you evict them? Do you give them first offer after rehab? Do they need 30 days notice? I want to treat people like I would want to be treated, but I also need to do what is best for me. 

Thanks!
