Find Your Papers
Before you exhaust yourself trying to get the fingerprints off the walls, locate all the important papers you'll need to entice a potential buyer. The operating manuals for your appliances and HVAC system, notes about the paint colors you used on your walls and any applicable warranties are important to have on hand. They'll show the listing agent that you have things under control, even if you don't.
While you're at it, pull out your old utility bills. You're probably still in denial about having to pay for the water coming out of the tap -- and going down the drain -- but work through the pain. Those seasonal totals may help make your home look more appealing than the house one county over from you.
