Inheriting M2M tenant who smokes - give them the boot?

[Joel Hecker]

I'm debating buying a 3 unit where the existing tenant in the top unit clearly smokes in the unit (cigarette in ash tray in listing photo). Do I ride him out and take the guaranteed money, then mitigate after he leaves? Or do I set a no smoking policy, evict him, mitigate, and hope to find a non-smoking tenant now? I'm out of state, so I can't smell it.
