N.C. Gen. Stat. § 54-109.65
A credit union may loan to its members for such purpose and upon such security and terms as the board of directors prescribes at rates of interest not exceeding eighteen percent (18%) annual percentage rate, unless a greater rate not to exceed the annual percentage rate permitted to be charged by federally chartered credit unions, is otherwise approved by the Credit Union Commission. Such action by the Commission will be uniform and apply to all credit unions.
The term "interest," as used in this section, shall not be deemed to include charges made by a credit union for appraisals of real or personal property; attorneys' fees for searching title to real property, preparing notes, deeds of trust, mortgages and closing loans; and recording fees. Rate of interest and terms of repayment shall appear on each note but the corporation may, for the purpose of making loans, discount and negotiate promissory notes and deduct in advance, from the proceeds of such loan, interest at a rate not to exceed the rate herein fixed, which shall be the legal rate for corporations organized under this Article, and such deductions shall be made upon the amount of the loan from the date thereof until the maturity of the final installment, notwithstanding that the principal amount of such loan is required to be repaid in such installments.
