If they have truly been there for several years, a repaint and new flooring was probably already needed.I caution owners buying properties that 50-75% of the time you lose tenants when a place sells...

WA statute RCW 59.18.280 requires that Within fourteen days after the termination of the rental agreement and vacation of the premises ..... the landlord shall give a full and specific statement of the basis for retaining any of the deposit together with the payment of any refund due the tenant under the terms and conditions of the rental agreement.They left the unit in reasonable condition, but due to damages done by their small children denting the wood framing around the interior doors along with a bunch of other items needing to be fixed and/or repainted, I spend more than $1100 and sent them an itemized statement showing my costs for labor and materials, which consumed their entire 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.

German roaches were even crawling out of the fridge door seals, and had developed language skills they were that advanced.In my wife's defense, she had her crew in, cleared, cleaned and repainted the place before I managed to get back into town. to this day I haven't seen the photos.

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.

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

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.  

I would also consider repainting at least some of the rooms to give it division.
