Sec. 3. "Bona fide discount points" means loan discount points that:
(1) are knowingly paid by the borrower;
(2) are paid for the express purpose of reducing the interest rate applicable to the loan;
(3) reduce the interest rate from an interest rate that does not exceed the benchmark rate; and
(4) are recouped within the first four (4) years of the scheduled loan payments;
if the reduction in the interest rate that is achieved by the payment of the loan discount points reduces the interest charged on the scheduled payments so that the borrower's dollar amount of savings in interest during the first four (4) years of the loan is equal to or greater than the dollar amount of loan discount points paid by the borrower.
