(A) Installment obligations. A right to installment or other deferred payments from the disposition of an interest in real property will constitute an interest solely as a creditor if the transferor elects not to have the installment method of section 453(a) apply, any gain or loss is recognized in the year of disposition, and all tax due is timely paid. See section 1445 and regulations thereunder for further guidance concerning the availability of installment sale treatment under section 453. If an agreement for the payment of tax with respect to an installment sale is entered into with the Internal Revenue Service pursuant to section 1445, that agreement may specify whether or not the installment obligation will constitute an interest solely as a creditor. If an installment obligation constitutes an interest other than solely as a creditor then the receipt of each payment shall be treated as the disposition of an interest in real property that is subject to section 897(a) to the extent of any gain required to be taken into account pursuant to section 453.
