Can you briefly outline the requirements I must comply with if I put any loan information, such as the monthly payment or interest rate, in an ad?

If the ad contains loan information, those terms must be available to a qualified borrower. If a rate of finance charge is set out (interest, points, loan fees), then the words "annual percentage rate (APR)" must be used. The advertisement must state the APR and whether the finance charge can increase over the term of the loan. If the advertisement contains information about the down payment, term, payment amount, or finance charge, then all of the following information must be disclosed: down payment, term, APR, and whether the rate may be increased. Mentioning only the APR will not trigger the additional disclosures. If specific information other than the APR is mentioned, such as the loan amount, down payment, etc., then the disclosures are triggered.
