There are things a homeowner can do to ensure that the home is appraised for maximum value
1. Information is King--The first one should be a packet of information that you can hand the appraiser as he or she speeds out the door after the inspection. This packet should contain not only the basics about your home but anything that will help back up the buyer's offer.
Include a fact sheet about the home with the address, the year the home was built the square footage, number of bedrooms and bathrooms, and the size of the lot. Also include a listing of recent sales in the area, especially if you know of any for-sale-by-owner homes that have sold or homes that sold for less than they should have for any reason
2. If It's Broken, Fix It --Fix anything that will age the home in the eyes of the appraiser.
3. Give the Home a Quick Cleaning--"Things like overgrown landscaping, soiled carpeting, marks on walls - those do affect value and are part of the property's overall condition rating," Dean Zibas, of Zibas Appraisal in San Clemente, California, tells the Wall Street Journal
