The OP indicated that the loan was being used to buy real property, but I agree the borrower would need to assess whether or not the interest is deductible ginve their facts and circumstances.
One of the criteria for deductibility is whether or not the loan is secured by the real property. Didn't sound to me like OP's situation meets that criterion. From the instructions on mortgage interest on Schedule A:
"A home mortgage is any loan that is secured by your main home or second home, regardless of how the loan is labeled. It includes first and second mortgages, home equity loans, and refinanced mortgages."
