Househacking a 4plex- one tenant has a criminal history?

[Ellie Narie]

I'm about to close on a 4plex pretty soon. One of the tenants has recently moved into one of the units, and this tenant has bankruptcies and a criminal history (this includes burglaries) that is recent. I'm not sure why the current property management company that the seller had in place let this tenant in. 

Any advice in general? I will have to live in one unit (one unit is already empty) and will be managing it myself. I'm getting security cameras set up, and some other security things done in my unit. Right now it's coronatime, so no one is allowed to evict anyone here, so I can't really do a non-renew right now.
