I realize this question is a little "stale" but here are a few things I think are very important:
1. Curb appeal. I can't tell you how many times I have driven to a home with a buyer and they decide not to even bother with going inside b/c the outside is so uninviting or simply neglected. First goal, get them in the door. Clean up the yard, plant some flowers, fix or replace any damaged lighting, etc.
2. Paint. A nice, neutral paint color can go a long way in making your home feel fresh. I like colors sich as Stone House or Shaker Beige by Ben Moore.
3. Updating fixtures - changing out dated lighting can make a huge difference in the look and feel of your home without hitting your wallet too much. Brass is out!
4. Concentrate on the kitchen and bath. It is true, they sell homes. If you have dated cabinets, you may be able to put new handles or pulls on them to update them a bit. If you don't have the money to invest in larger updates like new appliances or countertops, then make sure all things that were on the honey-do list are now on the honey-done list. And CLEAN, CLEAN, CLEAN. Same goes for the bathroom. Outdated faucets can be replaced, a fresh coat of paint can make a difference, and it is amazing what a re-grout of a shower will do!
I hope by now you have sold your home, but if not, good luck!
