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 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).
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.
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.
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.
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.
