Keep it neat! A clean, neat home allows buyers to see the "home" itself when previewing your property. Clutter tends to divert attention away from the key selling features of your home. Dirty dishes and messy rooms leave buyers with a negative impression of your property.
Be sure that all pets are securely closed within their cages or pet yards since some buyers have an aversion to animals.
Whether or not you are there when your home is previewed, the agent will be sure to advise you of the showing and provide you with constant updates accordingly.
