If you didn't notice anything inside, then a friendly conversation along the lines of "Hey, I noticed you smoking outside the last time I stopped by - I just wanted to thank you for doing that outside, and as long as you keep it outdoors, we'll be all good!"

It also states that any security deposit refunds owed will be made payable to all parties on the lease agreement.One tenant has stopped contacting the roommates and us, and we are not sure they are planning to return.

.- 12/13 the check of course bounces due to her putting a stop payment on the check- 12/13 I was notified that she turned off utilities on 12/12- 12/14 I provided her email stating I would be checking on the property on 12/15 (24 HR notice)- signed lease through August 2018- I have $1650 ($1350 rent and 300 pet deposit) in security deposits- upon checking on property I found that there are no items of value in my property and she had left all keys and garage door openers that I had originally provided her.

The next step I am considering is stopping contributing all together and putting that capital into our real estate investments.

If the borrower stops paying, they know they can take over the property and make more money by fixing it themselves.On the other hand, if you don't know these things, it is very risky. 

They will probably need to stop by to do an assessment. 

Today I decided to stop putting it off and joined up.

There are a lot of flaky buyers out there even ones that have money.Case in point one this week did not want to give financials so we stopped there.

That way they are more invested to continue to make payments. 100% seller financing can be risky if the market changes and your upside down on it, and the owners stop paying. 

@Angela Armstrong To begin with, you can inform your tenant of the issue, hoping this will prompt them to stop.
