Deductions & credits

Yes, if you sold the property for more than it cost you, you have a reportable taxable gain.   If there were no improvements, the basis is whatever you paid for the land in 2002.   The difference between that and what you sold it for is your long-term gain.   There is no depreciation taken on land.   Depending on your income level, your long term gains may not be taxable.  

Where do I enter a capital gain or loss?
