If the loan is secured by a dwelling on property that is primarily for agricultural purposes the loan is exempt from reporting regardless what the loan's purpose is.
Official Interpretation
Paragraph 3(c)(9)
1. Loan or line of credit used primarily for agricultural purposes. Section 1003.3(c)(9) provides that an institution does not report a closed-end mortgage loan or an open-end line of credit used primarily for agricultural purposes. A loan or line of credit is used primarily for agricultural purposes if its funds will be used primarily for agricultural purposes, or if the loan or line of credit is secured by a dwelling that is located on real property that is used primarily for agricultural purposes (e.g., a farm). An institution may refer to comment 3(a)-8 in the official interpretations of Regulation Z, 12 CFR part 1026, supplement I, for guidance on what is an agricultural purpose. An institution may use any reasonable standard to determine the primary use of the property. An institution may select the standard to apply on a case-by-case basis.
