If you want  your house to sell you have got to do things that will make it appeal to the buyer. We all keep our homes clean but you must remember that when it comes to showing your home to a client  lets be sure it is neat and well lighted as well.  If you want it to smell good you can put a drop of vanilla on the light bulbs just before they are to arrive to look it over. This also will mask pet and recent cooking smells. Have the outside in great shape. Yard cut and shrubs trimmed does wonders for curb appeal. Remember first impressions will be made when they pull into your drive way.
