I'm accused of not paying the mortgage for a home I was renting out.

I had a tenant accuse my contractor of smoking crack in the house and demand I decrease rent 

I think, for the most part, we have all failed to provide that person with the help and information they were truly seeking and have instead used this platform in the same way most people use facebook: to blurt out our personal opinions and accuse all those who disagree in any way of being shortsighted.  

No one would accuse Cozy of being a property manager - they're just a collection service that moves rent money from the tenant to the owner.

i think tenant is accusing me of building new apartments and installing grounding rod for propane lines gas guy installed cause im switching from paying all heat to each tenant pays own propane. 

So, maybe to get back she accuses her erstwhile employer of child abuse, on facebook of course. 

I know without hard evidence I can't make conclusions or accusations to tenant B, and at the end of the day can't control what individuals do, but is there anything I could do to maybe address or deter the issue?

Somebody wanting to sue for you backing out of a bad deal or accusing you of selling them a property with defects like unknown termite damage).

All this tells me you have probably never done a deal in your life and are just making wild accusations based on fear and negative propaganda. 

Instead of coming in here and and falsely accusing me of being a scammer or a fraud stay in the forums that actually involve what you’re interested in.
