It would be much more effective for you to invite a few Realtors to come and see your home and ask them.
Another idea is look at other listings and see which features they mention.
That the house is free of Clutter and Personal Items.
That the house does not smell.
That the house shows well; no holes in wall or doors.
That the house is priced right; comensurate with Market Value.
Reduce clutter: clean out closets, pick up clutter & pare down what's inside.
Pack away items & "collections" that you have throughout your house. When potential buyers are touring your home, you want them to focus on the house - not your stuff!
Tone down your creativity - you may be in love with the lime-green accent wall in your living room, but that may not appeal to potential buyers. You want your house to appeal to every poteneial buyer! When I'm showing houses to my buyer-clients, I always have them "name" the house: the house that smelled like cat ("The cat house"), the house with the great pool & deck ("The party house")...you don't want your house to be remembered as "the crazy paint house".
It doesn't stop on the inside...take a look at your curb appeal. How does your house stack up with the compitetion? Have your REALTOR take you to tour the houses on the market analysis, so you can see for yourself how your house compares to the others.
