We clean a lot of empty units, and after twenty years the pattern is very consistent. Landlords and property managers inspect the same short list, and tenants lose deposits over the same three things: the oven, the bathroom, and the carpet.
The oven is first because it is the easiest thing to score against you and the hardest thing to fake. Interior, racks, the glass in the door, and under the burners or the cooktop. Same logic for the refrigerator: shelves and drawers pulled out and washed, seals wiped, and the whole thing left running and empty rather than switched off and sealed shut.
Bathrooms get judged on grout, not on surfaces. Tile and grout scrubbed rather than wiped, hard water and soap film treated on glass and fixtures, the toilet cleaned behind and underneath, and the exhaust fan cover taken down and washed. That fan cover surprises people every single time.
Carpet is where the real money sits. Professional extraction on the way out costs a fraction of what a landlord charges to replace carpet, and in many leases the tenant is on the hook for the full replacement if it is stained. Get it extracted, and keep the receipt.
The rest of the walkthrough list: inside every cabinet and drawer, all closets including shelves and rods, baseboards, window tracks and sills, blinds, light fixtures and ceiling fans, switch plates, interior glass, and nail holes patched if your lease requires it. Take date-stamped photos of everything when you are done, including damage that was already there when you moved in.
Plan it for after the last box is gone and before you hand back the keys. An empty unit cleans faster, costs less to clean, and inspects far better than one with a couch still in it.
