I would heed this warning, especially with the numbers. 

I have good luck with them and they have low battery warnings but things can still happen. 

Also charging them a 50$ late fee (if it takes them more then 7 days to pay) im thinking maybe I tell them they need to start paying on the first and kinda frame it like a warning?

This is highly likely to get ugly - one of the occupants will hopefully move out on their own, unfortunately, it's highly likely one will stay.Sooner you hire an attorney the better, but not smoother, this will go.WHy haven't you reported the OD to the "guest's" pobation officer or warn the guest you will to force them out?

People don't believe it comes from the same water source...Be warned in our homes in Florida & Australia it is not.A lot of homes have recycled non-potable water fed back to the homes for outside watering etc.

I even tried syndications (as a LP,) and learned that I can do better on my own - at least without breaking promises/making myself a victim of fraud, the latter I warned others about on a deal I was being pitched (and time proved me right.)

This is what I would tell them.If the offending tenant was warned by police or cited by them as verified by a police report then I talk to them about it and follow up with a written lease violation warning aka notice to correct.

Last month I warned you of the coming heat.

Hey @Ethan Clay Lesperance, technically the lender could call the loan due for violating a possible clause in the loan agreement.I have been someone who has warned about this but so far, many folks have renting their former primary residences without issue with the lender.

Do you think the things you mentioned are bad enough to warn other hosts?
