I have a strict no smoking policy in my lease and she had to be a non smoker for me to even consider her as a tenant. 

Busted doors inside, cigarette butts everywhere outside, dog pee soaked into the carpets and padding, beer splashes all over the walls, complaints from neighbors.

Upstairs unit is already rented by a single woman who has been in it 3 years, smoker with a dog.

Laundry room etiquette, where to put cigarette butts, outdoor furniture rules, etc.

If it's clean and has a bunch of updates I don't want anything to do with it.I want the piece of garbage that smells like cigarettes and is infested with rats.

I did go check it out after and it still reeked of the cigarettes they were chainsmoking all week along with some used band-aids hanging from door frame (meth stuff?)

Pot smokers in another apartment. 

It has created a weird/hostile like dynamic between smokers and non-smokers who live on site, however.

I feel like I should just send a friendly reminder-like letter saying that the lawn care is their responsibility, as well as picking up the cigarette butts as I posted about earlier.
