The Bureau shall prescribe regulations to carry out the purposes of this subchapter. Except with respect to the provisions of section 1639 of this title that apply to a mortgage referred to in section 1602(aa) ^[1] of this title, such regulations may contain such additional requirements, classifications, differentiations, or other provisions, and may provide for such adjustments and exceptions for all or any class of transactions, as in the judgment of the Bureau are necessary or proper to effectuate the purposes of this subchapter, to prevent circumvention or evasion thereof, or to facilitate compliance therewith.

The Bureau shall publish a single, integrated disclosure for mortgage loan transactions (including real estate settlement cost statements) which includes the disclosure requirements of this subchapter in conjunction with the disclosure requirements of the Real Estate Settlement Procedures Act of 1974 [12 U.S.C. 2601 et seq.] that, taken together, may apply to a transaction that is subject to both or either provisions of law. The purpose of such model disclosure shall be to facilitate compliance with the disclosure requirements of this subchapter and the Real Estate Settlement Procedures Act of 1974, and to aid the borrower or lessee in understanding the transaction by utilizing readily understandable language to simplify the technical nature of the disclosures. In devising such forms, the Bureau shall consider the use by creditors or lessors of data processing or similar automated equipment. Nothing in this subchapter may be construed to require a creditor or lessor to use any such model form or clause prescribed by the Bureau under this section. A creditor or lessor shall be deemed to be in compliance with the disclosure provisions of this subchapter with respect to other than numerical disclosures if the creditor or lessor (1) uses any appropriate model form or clause as published by the Bureau, or (2) uses any such model form or clause and changes it by (A) deleting any information which is not required by this subchapter, or (B) rearranging the format, if in making such deletion or rearranging the format, the creditor or lessor does not affect the substance, clarity, or meaningful sequence of the disclosure.
