Notwithstanding the limitations specified in any mortgage, or imposed by a borrower by means of serving and recording a notice of limitation:
shall be secured by the mortgage, even though the mortgage does not specifically provide for future advances, or the advances or disbursements cause the amount of the total indebtedness to exceed the principal amounts stated in the mortgage, or to exceed the credit limit under an open-end mortgage. The priority of the lien of the mortgage, including any advance, increase, or disbursement described in this section, shall be the same as if such advance, increase or disbursement was made on the date of the recordation of the mortgage.
