(a) Notwithstanding any statutory or contractual provision to the contrary, in a consumer credit installment sale contract with an amount financed of five thousand dollars ($5000.00) or more secured by real estate or by a residential manufactured home as defined in G.S. 143‑145(7), any buyer may satisfy the debt in full at any time before maturity, and in so satisfying the debt, shall be credited with all unearned finance charges as computed on the simple interest or actuarial method.
(b) If a seller obtains a judgment on a debt arising out of a consumer credit installment sale described in subsection (a) of this section, or if the seller forecloses or repossesses the collateral securing the debt, the seller shall credit the buyer with all unearned finance charges as computed on the simple interest or actuarial method as if the payment in full had been made on the date the judgment was obtained or 15 days after the foreclosure or repossession occurred, whichever is earlier. If the seller obtains a judgment and repossesses the collateral, the seller shall credit the buyer with all unearned finance charges as if payment in full had been made on the date of the judgment or 15 days after the repossession, whichever occurs earlier.
