[Mike9241]

cost less deprecition. depreciation recapture is part of the capital gain that can have a special tax rate of 25%

That would be the cost basis of the assets sold, which would be the cost basis of your assets that you originally entered less the depreciation allowed on them during the time the property was rented. The original cost basis would usually be what you paid for the property and furnishings, but if the fair market value of the property was less than its cost when you started renting it out, the original cost basis would be its fair market value.
