Most real estate advice tells you to work on the outside of the house first, but unless there is a major project involved, we believe it is best to do it last. There are two main reasons for this. First, the first steps in preparing the interior of the house are easier. They also help develop the proper mind set required for selling - beginning to think of your "home" as a marketable commodity. Second, the exterior is the most important. A homebuyer’s first impression is based on his or her view of the house from the real estate agent’s car.
So take a walk across the street and take a good look at your house. Look at nearby houses, too, and see how yours compares.
