Sherry,
What you want to get and what the market will bear are rarely the same number. Factors influencing sale price:
1.location, 2. tax assessment, 3.condition,4. finished or unfinished,5. comparison with recent sales of similar sized structures in the area, 6.curb appeal and probably some others.
Recommend you contact the local realty folks who handle properties in your est of price range.
Any realtor worth his salt will come up with a good market price.
good luck,
