2. Principal residence. Section 1003.4(a)(6) requires a financial institution to identify whether the property to which the covered loan or application relates is or will be used as a residence that the applicant or borrower physically occupies and uses, or will occupy and use, as his or her principal residence. For purposes of § 1003.4(a)(6), an applicant or borrower can have only one principal residence at a time. Thus, a vacation or other second home would not be a principal residence. However, if an applicant or borrower buys or builds a new dwelling that will become the applicant's or borrower's principal residence within a year or upon the completion of construction, the new dwelling is considered the principal residence for purposes of applying this definition to a particular transaction.
Based on this from 1003.4(a)(6)(2) "However, if an applicant or borrower buys or builds a new dwelling that will become the applicant's or borrower's principal residence within a year or upon the completion of construction, the new dwelling is considered the principal residence for purposes of applying this definition to a particular transaction".....i would report as a primary residence, based on the information you provided. I understand that your scenario isn't a purchase, but i feel like the same logic can be applied.
