Multi Units: More Destructive Tenants? What's To Be Expected

[G W]

I’ve dealt with one bad tenant that did some dumb things like set an iron on new carpet in a bedroom, stained several spots in the living room, broke the lease and left early, etc… ended up keeping her security deposit so the damages were sort of evened out. The current tenant has been great so far and inspections of the property show she is taking care of the place.
I’m looking at a couple of 2-units and wondered what you folks have dealt with; relative to your single family rentals? Most of the 2-units I’ve seen seem to have a “higher risk” type of tenant, but on paper they look like they will cash flow Much better.
I know much of this can be sorted out through screening of tenants, picking up the rent in person (then glancing around to make sure things are OK), etc…
What have been your experiences??
