I am in a similar situation. The only thing being that I believe my tenant when she denies the claims. Three complaints have been made — damage to communal property, noise and defacing the front of the apartment. I know for a fact that the front of the apartment has never been defaced because I drive by often. I therefor think the complainants have the wrong apartment. Management company won't even listen to that opinion and keep sending me fines — which I am not paying due to any lack of proof.
Any ideas how to resolve this? My tenant is threatening the management company with legal action for defamation. Again, they don't seem to care.
