What piece of information must be disclosed in a mortgage loan advertisement?

In mortgage loan advertisements, it is essential to disclose the Annual Percentage Rate (APR). The APR provides borrowers with a clear understanding of the total cost of borrowing, expressed as a yearly interest rate, which includes both the nominal interest rate and any associated fees or costs over the life of the loan. This transparency is critical for consumers, as it allows them to compare different mortgage offers effectively and make informed financial decisions.

Including the APR in advertisements is a regulatory requirement that helps ensure that lenders present their products truthfully and without obscuring the real cost of borrowing. As a result, this disclosure promotes fair lending practices and protects consumers from misleading marketing tactics.

The other options—current housing market trends, the history of the lender's license, and minimum credit score requirements—while informative and relevant in certain contexts, do not carry the same regulatory weight or necessity in comprehensive advertisements as the APR.
