I don't know where Albertsville is....so you may need to talk with a CPA that knows your state's laws
Generally speaking capital gains (I am NOT a CPA) is the cost you paid, plus improvemements.
So Capital gains would be the tax on the difference between what you paid, versus the price you sell, less improvements. Soif you might be looking at a couple of thousand dollars in gain. There are short term and long term capital gains, less than a year is short term.
However, I don't mean to burst your bubble, but the gain will only be a problem is you sell. In most markets, owners selling on their own have two characteristics: They either do not sell and list with a Realtor, or if they do sell, they sell for less than market price.
I would like to encourage you to please consider at least interviewing a couple of Realtors. Ask them to prepare an "estimate of sellers net proceeds". Then you work the numbers.
