Again no ... you are not a bank or mortgage company so you do NOT need to file a 1098 ... read the rules.
What you do need to have is an agreed upon amortization schedule and the payer will enter your name, address & tax ID number on their Sch A and you will in turn enter the interest they pay you on your Sch B and enter their name, address & ID number ... this is why you do NOT need to file a 1098.
