Home staging is the arrangement of furniture and decorations to best highlights a home's good points while at the same time draw attention away from any negatives. At the same time it neutralizes a seller's personal taste in décor in order to appeal to as wide an audience as possible. Home staging is not interior decorating; it is marketing!
Buyers are going to look at many homes and it is the home that shows the best that is likely to be bought. Buyers equate a messy home with being a dirty home and a dirty home with being a poorly maintained home when in fact there is no correlation. Just because there is laundry on the floor does not mean that the sellers haven't serviced the furnace and taken care of the roof, but this is how buyers view it. Play into this view to your advantage. Make your home the best looking home and they will have a favorable feeling about it.
Even a vacant home can be staged by renting furniture. It is a misconception that an empty house looks bigger. A properly furnished house looks bigger. A vacant room is visually uninteresting - there is no focal point.
Here are two photos of a listing of mine at 16106 Edna St. both before and after home staging. The home was professionally staged.

Home staging is so important that I provide the services of a professional home stager to stage my listings at no cost to the seller!
