Final answer:
If an applicant chooses not to provide information about their ethnicity, race, and sex, a loan originator taking an application in person must select the option 'Prefer not to say' in those fields.
Step-by-step explanation:
If an applicant chooses not to provide information about their ethnicity, race, and sex, a loan originator taking an application in person must select the option 'Prefer not to say' in those fields. According to federal regulations, if an applicant does not disclose this information, the lender is required to note it based on visual observation and surname if the application is made in person. It is important to note that the law prohibits discrimination based on the absence of this information, and the applicant should not be discriminated against or penalized for choosing not to provide it.
