A bargain sale of property is treated as part gift and part sale. The charitable deduction for the gift portion equals the total value of the property, less the total amount of consideration paid by the charity, including any debt to which the property is subject.(1) If you specify that the bargain sale is subject to the reduction rules for ordinary income and short term capital gain property, the charitable deduction is calculated by reference to the cost basis allocated to the gift portion of the bargain sale.(2)
