My sister has a personal loan for the purchase of her manufactured home, issued by the owner. She'd like to be able to deduct the loan interest from her taxes.
As far as I can tell from IRS instructions, a contract that contains a loan to purchase a manufactured home is considered a mortgage, and the interest paid on that mortgage is deductible in federal taxes (we have no state tax).
Is it typical for a personal mortgage issuer to create a 1098? If not, as a payer is there a less formal method which is acceptable for declaring deductible loan interest for tax purposes?
If no 1098 is received, what recourse does one have to declare the interest to deduct?
