Personally I'd rather have a tenant sniffing coke than smoking marijuana, which can leave an odor and possibly the need to re-paint after they leave.If they have been good otherwise, I would pretend I never saw this.

Also, why repaint the kitchen? 

Coming up to renewal, the tenant is asking if he could re-paint the house at my expense because he doesn't like the color (only been 2 yrs since the tenant moved in).

Now that it's done, there's no sense going back and repainting - instead, I would leave that front door light on to brighten the entrance, at night, during the day, anytime the house is being shown.Another thing I would consider, this house, like many newer homes, screams WELCOME TO MY GARAGE DOOR!  

We just put brand new carpet in the house in addition to repainting.

You can figure you will repaint the place every few years or at turn over.

@Chan S. my lease reads like this for early termination: Resident may terminate this agreement by doing all of the following: a) Giving Management sixty (60) days written notice, b) Paying all monies due through date of termination, c) Paying an amount equal to the Security Deposit as an Early Termination Fee, d) Returning dwelling in a clean, ready-to-rent condition, and e) Paying a pro-rated portion of expenses for repainting and cleaning based on the ratio of the number of months then remaining in the initial term to the number of months originally in the initial term.  

Heck, she already owes for the cleaning and repainting, and there's no deposit.  

Tenants are moving out this weekend as they've bought a house, they've been with us 2 years, so I'm sending in professional carpet cleaners next week - only thing i can think of.And like you, we repainted everything, cleaned everything, and it just hangs between the kitchen and living room.
