All joints between tiles should be clean and white. Use DAP bathroom tile sealer to reseal the joint between bathtub and wall and floor. All walls should be clean and free of gouges, scratches, smudges, scotch tape, posters, thumbtacks, etc. Walls should only have decorative items. Posters and paper pictures taped to walls should be removed and all evidence of the tape markings removed.
Nothing smells better than fresh air.
On warm days, have your windows open and shades up. Make your home feel and smell bright, fresh and clean and you will have a faster sale. Make very sure that there are absolutely no pet odors.
