u/s 50C the stamp duty valuation (if more than sale price) will be considered for computing capital gain. You cant take lower valuation/cost. The only option with you is to claim before the AO that the stamp duty value is more than the fair market value as on date of transfer. Then he may refer it to Valuation Officer. And if the fair market value determined by the Valuation Officer is lower than the stamp duty value, the AO may take such FMV.
