A. A mortgage or security interest shall secure additional funds that may be advanced by the mortgagee or secured party for the protection, preservation, repair, or recovery of the mortgaged or encumbered property, or the protection and preservation of the mortgagee's mortgage or secured party's security interest thereunder. A mortgage or security agreement may provide that the mortgagee or secured party may, at its sole election, purchase insurance or pay taxes on the mortgaged or encumbered property should the mortgagor or debtor fail to comply with its contractual obligations to do so.
B. Unless the mortgage or security agreement provides otherwise, all additional sums advanced by the mortgagee or secured party under the provisions of Subsection A are deemed to bear interest at the rate provided under the mortgage note or other secured indebtedness from the date of each such advance until repaid in full by the mortgagor or debtor.
C. Unless the mortgage or security agreement provides otherwise, the mortgage or security interest is deemed without further action to secure additional funds advanced by the mortgagee or secured party under the provisions of Subsection A, together with interest thereon.
