But Westerman said Shelford-Marsh didn't do that.
The landlord claimed the cost of repairs for damage to the premises, including a "significant number of holes in walls, broken windows, a broken fire door handle and carpet ruined throughout".
Shelford-Marsh also didn't return the keys and remove all the rubbish.
Tenancy Tribunal adjudicator R Lee said it took betterment and depreciation into account but was satisfied that the damage was "more than fair wear and tear" and had been caused intentionally.
The adjudicator ordered Shelford-Marsh pay her landlord $18,604.74 immediately.
