Does the house have any structural issues, or is this a cosmetic / update fixer-upper?
If the foundation, walls and roof are sound, I'd start going to open houses in your neighborhood, especially the ones like your house. Find out what the asking price is and what they are actually going for. I'd find three or four houses like yours and average their asking price. Know what they're going for so you have a good place to negotiate from.
For example, when we bought our house, market-priced homes (fixers) sold in a week or less for about $25,000 over the asking price, with multiple offers on each home. As a buyer, that was invaluable information to have, but I suspect that I'd also like to have it as a seller.
Also, if you aren't willing to work with a buyer's agent, you may find your stable of potential buyers much reduced.
I think Nords wrote a great post about this over at the Early Retirement forums -- here it is:

Good luck!
