In addition to all the practical information you can find about getting y0ur house ready to sell, a great piece of advice is to think like an auto detailing service. Think inside and out. Think crevices and q-tips.
Picture a newly constructed house — no marks on the walls, no signs of wear and tear, totally “unspoiled.” Imagine a new home sales consultant comparing their model home to a resale house that is lived in or worse “used.”
Now picture your house looking as new and un-lived in as possible. You need an eye for details here, Your time and effort and the efforts of excellent cleaners/painters/flooring experts to go room by room through your house to detail it will pay off. Once you have a detail-cleaned house, then your Realtor can sing the praises of your “better than new” house.
