Nev. Rev. Stat. § 675.367
2. The licensee shall notify a borrower of any increase in the rate of interest to be charged or any other change in the terms of the agreement for a loan for an indefinite term:
(b) At least 30 days before the change is to take place for all other loans for an indefinite term.
The change applies only to a debt incurred by the borrower after the effective date of the change, unless otherwise agreed by the borrower. In determining the balance to which an increase in the rate of interest applies, any payment received or other credit made to the borrower’s account applies to the balance existing before the date of that increase until that balance is paid in full.
