The audience knows it's not a good idea but they never seen to have a clue?

My guests did not tell me this during their stay, but it turns out that my regular tenant's guest was chain-smoking out the back door and throwing butts in the lawn.

I'm just throwing out some things to think about.

I think throwing out an offer first is a good way to negotiate.

LOL, in college my roommate set the apartment on fire by throwing a lit cigarette in a trash can. 

I'll bring the keys to his PM on Friday after it funds and I throw a couple GFCI outlets in the place for him as a closing gift.  

After hearing that, I had little faith that we’d be able to tie the property up but that’s never discouraged us enough to quit before, so I decided to throw in a number.

Likely when they move out you'll need to do some heavier clean-up and if you throw some upgrades on top of that, you may be able to substantially raise rent rates.

Alternatively, just throw up a license agreement through a basic web auth that prompts for guest name and email like every hotel chain anywhere is doing now except by asking for your room number and doing the math for you in their reservation system.

Instead of throwing $10,000 in tools on a high interest credit card, buy them from the last washout of the program who will let them go for a song.
