N.C. Gen. Stat. § 42A-15
A landlord or real estate broker may require a tenant to pay all or part of any required rent, security deposit, or other fees permitted by law in advance of the commencement of a tenancy under this Chapter if these payments are expressly authorized in the vacation rental agreement. If the tenant is required to make any advance payments, other than a security deposit, whether the payment is denominated as rent or otherwise, the landlord or real estate broker shall deposit these payments in a trust account in a federally insured depository institution or a trust institution authorized to do business in this State no later than three banking days after the receipt of these payments. These payments deposited in a trust account shall not earn interest unless the landlord and tenant agree in the vacation rental agreement that the payments may be deposited in an interest-bearing account. The landlord and tenant shall also provide in the agreement to whom the accrued interest shall be disbursed.
