Only things I can think of are HVAC filters (tenant every 3-6 months), batteries in smoke alarm (tenant twice a year). 

So if it's your first couple deals I do agree with you having an experienced buyer or 2 ready to go so you can reduce the possibility of them backing out, but after a while you'll realize who's legit and who's blowing smoke.

The owner is seeking a quiet, non-smoking responsible tenant to enjoy this great property.This unit is the only studio in the 02215 zip code with a deeded parking space.

If there is a new no smoking ordinance I post that.

If the tenant has somewhere else to go and isn’t getting a smoking deal they should move if they think their landlord is lying.

I had a renter/guy a few months back that I told to quit smoking pot inside.

Like others I was expecting that they replaced the entire unit.Your lease clearly states they need to replace the filters every 3 months, you shouldn't have to remind them but given this happened, I'd also check the furnace filters and anything else (batteries in smoke alarm).

Big burly guys that smell like diesel fuel, drive jacked up 4x4s, chew tobacco for breakfast and have neck tats. 

Since the wage issue does not want to go away, put that into your pipe and smoke it: 2 days ago I had my driveway sealed.

Wood burning fireplaces smoke up the entire, they stink and they are super dangerous.
