"The rent on this property has been due and unpaid for thirty consecutive days and the landlord believes that you have moved out and abandoned the property. The landlord may declare this property abandoned and remove your possessions from this unit and dispose of them unless you write to the landlord stating that you have not abandoned this unit within ten days of the landlord having both posted this notice on your door and mailing this notice to you. You should mail your statement by regular first class mail and, if you so choose, by certified mail, return receipt requested, to this address ______ (here insert landlord's name and street address)"; and
