I've been both a buyer and seller in both the hot market and the terrible market -- here are some tips:
Many buyers have no imagination. They have a hard time seeing past cosmetic issues. Additionally, very often buyers become emotional -- getting them hooked into seeing themselves living in your home is key. Based on that:
1. Get rid of wallpaper. It won't be a selling point to anyone, and may send some people headed for the hills.
2. Look at the finishes in your home. It is amazing how much lighting, door knobs and bathroom/kitchen fixtures can date a home. These items are not that expensive to replace.
3. Depending on the condition of your cabinets, consider putting in granite countertops if comps in your area have them, especially if you are at a price break. People often overestimate how much putting in granite costs. If it's on their must do list, they will deduct more than it would cost you to do it from their offer.
4. Consider changing the rose carpet -- or advertise an $XXX allowance for carpet change. That will help control terms of the negotiations.
5. Make sure everything is de-cluttered for every showing. Also, turn on at least one light per room and make sure all window coverings are open.
6. Fresh flowers sparingly, but strategically placed can be helpful, as can green plants (real or fake, but make sure they are dust free).
7. The smell of baking bread or cookies can be helpful. Try to avoid other cooking smells, though, if you can. If I had a last minute showing, I would pour a little vanilla on some tinfoil and warm in in the toaster oven while I was straightening up. House smelled like fresh baked cookies.
8. I would also turn classical music on very softly -- nothing that should be immediately noticeable, but would "warm" the space.
Good luck!
