Make sure you give your house a good cleaning, preferably by a professional, before you start showings. Try to minimize excess furniture or clutter in the house. Arrange furniture so it doesn't block windows. Make sure your closets are clean and tidy; potential buyers pay a lot of attention to closets. And make sure your windows are clean and sparkly, shrubs trimmed and flowerbeds weeded. The buyer's decision-making process begins at the curb, not the front door.
