Which of the following is defined as a 'triggering term' that requires the disclosure of the advertised mortgage loan's APR?

The required credit score is a criterion used by lenders to evaluate a borrower's creditworthiness, but it does not directly relate to the terms of the loan itself. It does not trigger the obligation to disclose the APR because it does not specify the financial cost or payment obligations of the loan.

The principal loan amount refers to the total sum of money borrowed, but it is not considered a triggering term for APR disclosure. While it is an important figure in understanding the loan, it does not provide information about the cost of borrowing, such as interest or payment terms.

The due date of the loan payment indicates when payments must be made but does not trigger the requirement for APR disclosure. This term focuses on payment timing rather than the financial details of the loan, which necessitate APR clarification for transparency.
