It is HMDA reportable as it is a dwelling and is considered construction to permanent. It would be exempt as temporary financing if it was construction only. See below for guidance from the regulation:
1003.2 Definitions: 5. Construction and permanent financing. A home purchase loan includes both a combined construction/permanent loan and the permanent financing that replaces a construction-only loan. It does not include a construction-only loan, which is considered “temporary financing” under Regulation C and is not reported.
