You're going to get the same answer from everybody, but it can't be repeated enough. Get a realtor to come out, preferably 2 or 3, or even more, and see what they say. And dont' pick an agent just because they give you the highest estimate. Because like Hank said in the beginning, you'll just wind up lowering your price, probably repeatedly, and most likely wind up selling for less than you would have otherwise.
Based on the neighborhood, you could be anywhere from 50-80% of your original purchase price. The fence, flooring, and crown molding will help, but it depends on what kind of fence as well as the size of the yard fenced, what kind of tile you installed, as well as where and what kind of crown molding. And things like crown molding may not actually add to the value, but may help you sell faster, which equates to less money out of your pocket in holding costs while marketing the property.
Again, get comparables. Sold comparables. The current for-sale list really doesn't tell you much. An actual appraisal would be better.
