Hi Fred & Ruby-
If you are very worried about this and if the statistics support your concerns, then consider staging the home (if it isn't already) and express your concerns to the stager. A professional stager will have plenty of inspiring ideas to help minimize any negative aspects and accentuate the positive characteristics of your home. They will compare your home to others in the area and a real pro will know how to utilize every inch of space to make it comparable or better than other 3 or 4 bedroom comps. For more information, you can take a look at my website (below) or check the Home Staging Resource directory for a home stager at http://www.homestagingresource.com.
