The disclosures required by this section shall be given not less than 3 business days prior to consummation of the transaction.
After providing the disclosures required by this section, a creditor may not change the terms of the extension of credit if such changes make the disclosures inaccurate, unless new disclosures are provided that meet the requirements of this section.
The Bureau may, if it finds that such action is necessary to permit homeowners to meet bona fide personal financial emergencies, prescribe regulations authorizing the modification or waiver of rights created under this subsection, to the extent and under the circumstances set forth in those regulations.
A mortgage referred to in section 1602(aa) 1 of this title may not contain terms under which a consumer must pay a prepayment penalty for paying all or part of the principal before the date on which the principal is due.
For purposes of this subsection, any method of computing a refund of unearned scheduled interest is a prepayment penalty if it is less favorable to the consumer than the actuarial method (as that term is defined in section 1615(d) of this title).
A mortgage referred to in section 1602(aa) 1 of this title may not provide for an interest rate applicable after default that is higher than the interest rate that applies before default. If the date of maturity of a mortgage referred to in subsection  1602(aa) 1 of this title is accelerated due to default and the consumer is entitled to a rebate of interest, that rebate shall be computed by any method that is not less favorable than the actuarial method (as that term is defined in section 1615(d) of this title).
No high-cost mortgage may contain a scheduled payment that is more than twice as large as the average of earlier scheduled payments. This subsection shall not apply when the payment schedule is adjusted to the seasonal or irregular income of the consumer.
A mortgage referred to in section 1602(aa) 1 of this title may not include terms under which the outstanding principal balance will increase at any time over the course of the loan because the regular periodic payments do not cover the full amount of interest due.
A mortgage referred to in section 1602(aa) 1 of this title may not include terms under which more than 2 periodic payments required under the loan are consolidated and paid in advance from the loan proceeds provided to the consumer.
A creditor shall not engage in a pattern or practice of extending credit to consumers under mortgages referred to in section 1602(aa) 1 of this title based on the consumers’ collateral without regard to the consumers’ repayment ability, including the consumers’ current and expected income, current obligations, and employment.
No creditor shall recommend or encourage default on an existing loan or other debt prior to and in connection with the closing or planned closing of a high-cost mortgage that refinances all or any portion of such existing loan or debt.
If a payment is otherwise a full payment for the applicable period and is paid on its due date or within an applicable grace period, and the only delinquency or insufficiency of payment is attributable to any late fee or delinquency charge assessed on any earlier payment, no late fee or delinquency charge may be imposed on such payment.
If, in the case of a loan agreement the terms of which provide that any payment shall first be applied to any past due principal balance, the consumer fails to make an installment payment and the consumer subsequently resumes making installment payments but has not paid all past due installments, the creditor may impose a separate late payment charge or fee for any principal due (without deduction due to late fees or related fees) until the default is cured.
No high-cost mortgage may contain a provision which permits the creditor to accelerate the indebtedness, except when repayment of the loan has been accelerated by default in payment, or pursuant to a due-on-sale provision, or pursuant to a material violation of some other provision of the loan document unrelated to payment schedule.
Any mortgage that contains a provision prohibited by this section shall be deemed a failure to deliver the material disclosures required under this subchapter, for the purpose of section 1635 of this title.
For purposes of enforcement by the Federal Trade Commission, any violation of a regulation issued by the Bureau pursuant to subsection (l)(2) shall be treated as a violation of a rule promulgated under section 57a of this title regarding unfair or deceptive acts or practices.
A creditor, successor in interest, assignee, or any agent of any of the above, may not charge a consumer any fee to modify, renew, extend, or amend a high-cost mortgage, or to defer any payment due under the terms of such mortgage.
Except as provided in subparagraph (B), no creditor or servicer may charge a fee for informing or transmitting to any person the balance due to pay off the outstanding balance on a high-cost mortgage.
When payoff information referred to in subparagraph (A) is provided by facsimile transmission or by a courier service, a creditor or servicer may charge a processing fee to cover the cost of such transmission or service in an amount not to exceed an amount that is comparable to fees imposed for similar services provided in connection with consumer credit transactions that are secured by the consumer’s principal dwelling and are not high-cost mortgages.
Prior to charging a transaction fee as provided in subparagraph (B), a creditor or servicer shall disclose that payoff balances are available for free pursuant to subparagraph (A).
If a creditor or servicer has provided payoff information referred to in subparagraph (A) without charge, other than the transaction fee allowed by subparagraph (B), on 4 occasions during a calendar year, the creditor or servicer may thereafter charge a reasonable fee for providing such information during the remainder of the calendar year.
A creditor may not extend credit to a consumer under a high-cost mortgage without first receiving certification from a counselor that is approved by the Secretary of Housing and Urban Development, or at the discretion of the Secretary, a State housing finance authority, that the consumer has received counseling on the advisability of the mortgage. Such counselor shall not be employed by the creditor or an affiliate of the creditor or be affiliated with the creditor.
No counselor may certify that a consumer has received counseling on the advisability of the high-cost mortgage unless the counselor can verify that the consumer has received each statement required (in connection with such loan) by this section or the Real Estate Settlement Procedures Act of 1974 [12 U.S.C. 2601 et seq.] with respect to the transaction.
The Board  may prescribe such regulations as the Board determines to be appropriate to carry out the requirements of paragraph (1).
