Those that will be staying with the home should be in good working condition. If specific equipment does not work and you do not intend to repair it, point this out. Leaky or excessively noisy toilets should be fixed, as well as any dripping faucets. These should be working properly with no broken heads and sidewalk over spray kept to a minimum. One of the best and least expensive ways to improve the showability of your home is to open up as much space as possible.
Openness stimulates positive feelings in the mind of buyers.
You can't change the size of the rooms, but you can try presenting them in a pleasing way. One of the most frequently voiced requirements of buyers is for closet and storage space. Open up your storage area by getting rid of items you aren't using. The same principle applies here. Overcrowding gives the impression of inadequacy.
