Proceeds from the sale of the property that are received after transfer of title and that are unrelated to the modifications made subsequent to the transfer of title are not considered gross proceeds of sale or gross income from the modifications.
2. 2. If the original owner enters into an agreement separate from the contract for sale of the real property providing for amounts to be paid to the original owner for the modifications to be made in the period subsequent to the transfer of title to the property, the amounts are included in the original owner's gross proceeds of sale or gross income received for the modifications made subsequent to the transfer of title.
3. 3. If the original owner is responsible to the new owner for modifications made to the property in the period subsequent to the transfer of title and derives any gross proceeds of sale or gross income from the project subsequent to the transfer of title other than a delayed disbursement from escrow unrelated to the modifications, it is presumed that the amounts are received for the modifications made subsequent to the transfer of title unless the contrary is established by the owner through its books, records and papers kept in the regular course of business.
