Pack away piles of paper, especially any sensitive information such as passwords, confidential work documents and similar items.
Keep cords out of the way, and just as in every room, remove clutter and excess furniture.
Make sure it's completely clutter-free, with space for shoes and coats, depending on the season.
If there's a table, add a floral arrangement or another single beautiful decorative item.
GARAGE & LAUNDRY ROOM
These are lower-priority areas but ensure there's no laundry hanging or piled up, ensure the washer and dryer are clean, organize tool/equipment and ensure there's enough room in the garage to park the car.
