(b) such part, if any, of the amount so received by the taxpayer as has been repaid by him pursuant to a legal obligation to repay all or any part of that amount, in respect of that property and before the disposition thereof by him, and as may reasonably be considered to be in respect of the amount elected under this section in respect of the property.
