There is a real difference between tidying a photograph and misrepresenting a property, and it sits exactly where you would expect: clutter is yours, defects are the property's. Removing a laundry basket, a bin bag or a tangle of chargers changes nothing a buyer is buying. Removing damp on a ceiling, a crack in a wall, a broken window or the extension your neighbour built is a different act entirely, and in most markets it is the kind of thing that gets a listing pulled and an agent in trouble.
This tool is scoped for the first kind of edit. The instructions keep the room's structure, surfaces and finishes intact and remove movable items — which means it will clear the boxes stacked against a wall but will not repaint the wall behind them.
Where the edit is substantial, disclose it. Many markets and MLS policies require enhanced or edited photographs to be labelled, and doing so costs you nothing while protecting the sale. If a buyer would be surprised standing in the room, the photo went too far.
