Which of the following must be included in advertisements displayed by mortgage loan originators (MLOs)...

Under Regulation Z (TILA), when mortgage loan originators (MLOs) advertise mortgage services, including payment amounts, they must disclose the Annual Percentage Rate (APR). The APR reflects the total cost of the loan, including interest and certain fees, and provides a clear picture of the loan's true cost over time.

Failure to include the APR in an advertisement that mentions payment amounts, interest rates, or other specific loan terms is considered a violation of TILA’s advertising requirements.

Other details (B, C, D), such as the MLO's website or the number of days the rate is available, are not mandatory in all advertisements, but the APR is required.
