Interior layout — DO:Incorporate a smooth and open layout. Anything that feels too cramped or doesn't make sense might need help from a good contractor before going on the market. Think about potential. Does a basement have the capability of turning into a media room, or are the ceilings too low? Fix negative features when possible. Small bathrooms, rooms that are accessed through other rooms, slanted second-floor ceilings and small kitchens can be a downside.DON'T worry about changing features that are common for the home's age and area. Appraisers do take into account the way the home functions in the area and for its age. "In Atlanta, the downtown-area homes built in the 1920s had two bedrooms and one bathroom, which is common for this area. But that house wouldn't function properly in suburban Atlanta, with newer homes that have three to four bedrooms," says Mark Skapinetz of What's It Worth? Appraisals.
