The following is from the preamble to the Reg B Valuation rules:
Footnote 32 states: Similarly, questions about the rule’s coverage of temporary loans, such as bridge or construction loans, and renewals of credit, relate to the overall scope of Regulation B. The final rule is not intended to address whether these loans are subject to ECOA in the first place. If a temporary loan or a renewal is subject to ECOA, and a an appraisal or other written valuation is developed for that loan, then the applicant has a right to receive a copy under the final rule. This approach is consistent with existing comment 14(a)(1)-2 concerning the application of § 1002.14 to renewals, which is maintained in the final rule.
