Seller financing is an equity based loan, look to the UCC as to default of installment contracts, they become void, points or loan fees are not charged on equity financing.......I said not charged when I should say, should not be charged as I'd bet sellers are not in compliance, they can just lose their note and suffer any consequence that goes with unlawful lending.
