Appeal of Mapes

*856OPINION.

There is no evidence in this appeal as to the cost of the property; its value at the time of the conversion thereof from residential property into business property; the March 1,1913, value; or the sale price. The Board, therefore, has no facts before it on which it can base a decision that the determination of the Commissioner that no deductible loss was sustained from the sale of the property was in error.
