All this talk about the Landlord Tenant Act with regard's to the poster's liability is utterly erroneous, as there are issues of surety, guaranty, and statute of fraud at play. 

Once a tenant utters the mold word you pretty much know what you have paying you rent and that alone paints her to me as someone you made a mistake renting to no matter how nicely she decides to play in the short-term.

I'm not getting into numbers of units that I own as that is utterly gauche, and nor do I feel the need to use it to justify my position.

IMO, that is utter nonsense. 

:As for your comment regarding feeling guilty about raising rents there is no place for emotions when it comes to money. ...says the guy who blows a vessel every time the phrase "cash for keys" is uttered.

Don't misunderstand we don't let our tenants chill out in the property without paying but we most certainly pick out battles. 

Now Steve, he might just need to get some permanent, passive income to help him chill out. 

More importantly choosing Airbnb over hotels offers authentic, local experiences utterly missed in chain hotels.

So it was an utter waste of time. 

Tenants expect to pay market rent, they expect a annual rent increase and will never utter a thank you if you don't do either.
