Illumination is like a welcome sign. The potential buyers will feel a glowing warmth when you turn on all your lights for a showing, day or evening. Wash dishes, put away clothes, straighten up newspapers, etc. Make up beds with attractive spreads. Keep pets out of the way when showing.
Many people are allergic to animals.
Avoid having too many people present during inspections. The potential buyer will feel like an intruder and will hurry through the house. Do not allow children to tag along on the visitor's tour. Leave the showing to the salesperson. The salesperson knows the buyer's requirements and can best emphasize the features of your home.
