The basis upon which the allowance for depreciation is to be computed with respect to any property shall be the adjusted basis provided in section 1011 for the purpose of determining gain on the sale or other disposition of such property. In the case of property which has not been used in the trade or business or held for the production of income and which is thereafter converted to such use, the fair market value on the date of such conversion, if less than the adjusted basis of the property at that time, is the basis for computing depreciation.
