Residential rental in NSW, periodic (month to month) lease and a 90 day no grounds notice has been given to vacate. I am aware that the tenant can leave before the notice period ends and only pay rent until the day they leave, and section 110 of the NSW act supports that. The question is whether the tenant is required to give a certain amount of notice that they are leaving in this scenario. My reading of the act is that they don't have to, however the property manager in this case is running the line that 21 days notice is still required, as would be the case if the landlord had not given notice. Can anyone clarify this?
