Thank you for your question. I will try to assist you in answering it today but please feel free to ask as many follow up questions as you like until you are 100% satisfied.
Even though the truth is a defense against defamation I strongly advise against the intended action. Also, truth has a second leg that must be present if you are to use it as a defense. The defamer must prove that the material (defamatory statements) is substantially true and that the public has an advantage or legitimate interest in the material. Both elements must be proven. I can almost guarantee you that it will not have the required result if you proceed to publish the intended advert and it will cause you much stress and heartache and you may end up having to defend yourself against a claim in any event even if you might have a defense.
My advise would be to rather get legal advise to establish if you have cancelled the contract legally and if everything there is sound or else they might deny valid cancellation and stay on in the house.
Secondly, there is no reason whatsoever that you can not sue them for arrears at this stage already and get the sheriff to attach and sell their property if they do not pay. In fact, I always suggest to clients to issue summons while they are still on the property as you will not know where they are moving to later on to serve the summons and the warrant of execution. Also, my experience is that very often when the sheriff attaches property of tenants, they will vacate the property themselves saving you the costs of having to evict them later.
I hope this answered your question.
