(c) At least 90 days but not more than 150 days prior to the due date of the final payment on a loan that is subject to this section, the holder of the loan shall deliver or mail by first-class mail, with a certificate of mailing obtained from the United States Postal Service, to the trustor, or his or her successor in interest, at the last known address of that person, a written notice which shall include all of the following:

1. (1) A statement of the name and address of the person to whom the final payment is required to be paid.
2. (2) The date on or before which the final payment is required to be paid.
3. (3) The amount of the final payment, or if the exact amount is unknown, a good faith estimate of the amount thereof, including unpaid principal, interest and any other charges, such amount to be determined assuming timely payment in full of all scheduled installments coming due between the date the notice is prepared and the date when the final payment is due.

4. (4) If the borrower has a contractual right to refinance the final payment, a statement to that effect.

   If the due date of the final payment of a loan subject to this section is extended prior to the time notice is otherwise required under this subdivision, this notice requirement shall apply only to the due date as extended (or as subsequently extended).

(d) For purposes of this section:

1. (1) A “balloon payment loan” is a loan which provides for a final payment as originally scheduled which is more than twice the amount of any of the immediately preceding six regularly scheduled payments or which contains a call provision; provided, however, that if the call provision is not exercised by the holder of the loan, the existence of the unexercised call provision shall not cause the loan to be deemed to be a balloon payment loan.
2. (2) “Call provision” means a loan contract term that provides the holder of the loan with the right to call the loan due and payable either after a specified period has elapsed following closing or after a specified date.
3. (3) “Regulation Z” means any rule, regulation, or interpretation promulgated by the Board of Governors of the Federal Reserve System under the Federal Truth in Lending Act, as amended (15 U.S.C. Sec. 1601 et seq.), and any interpretation or approval thereof issued by an official or employee of the Federal Reserve System duly authorized by the board under the Truth in Lending Act, as amended, to issue such interpretations or approvals.

(f)

1. (1) The validity of any credit document or of any security document subject to the provisions of this section shall not be invalidated solely because of the failure of any person to comply with this section. However, any person who willfully violates any provision of this section shall be liable in the amount of actual damages suffered by the debtor as the proximate result of the violation, and, if the debtor prevails in any suit to recover that amount, for reasonable attorney’s fees.
2. (2) No person may be held liable in any action under this section if it is shown by a preponderance of the evidence that the violation was not intentional and resulted from a bona fide error notwithstanding the maintenance of procedures reasonably adopted to avoid any such error.
