We are currently running a webpage e-mail add that contains a mortgage calculator. The data in the calculator is manipulated and input by the user (rate, loan amount, term) and will then calculate a payment. To remain compliant with Reg Z are we required to include APR, downpayment, and terms of repayment? Or since we are not providing the rate, loan amount information, and term (input by user) are we exempt from this requirement? Should we include some other type of disclaimer? (terms, rate, etc not deemed reliable)
