Wear and tear is to be expected in any rental property, and it’s reasonable that there’ll be scuff marks or the carpet will be more worn. It’s also fair to assume that after a while, the electrical items you provide will need replacing.
Having a comprehensive inventory list for a rental property makes it much easier to distinguish between wear and tear and damage. For example, marks on walls, peeling wallpaper and loose edges on carpets can all be considered fair wear and tear. Whereas large sections of ripped wallpaper, heavily stained or soiled carpets, smashed doors, walls and furniture can all count as ‘damage’. An inventory with photos also serves as evidence if you need to claim damages.
