I agree with that assessment. See commentary below:
Paragraph 3(c)(3)
1. Temporary financing. Section 1003.3(c)(3) provides that closed-end mortgage loans or open-end lines of credit obtained for temporary financing are excluded transactions. A loan or line of credit is considered temporary financing and excluded under § 1003.3(c)(3) if the loan or line of credit is designed to be replaced by separate permanent financing extended by any financial institution to the same borrower at a later time.
