Here is the specific conforming guideline, so this will apply to those lenders who would offer you the best terms on fixed rate loans, for example:
"Deferred installment debts, such as deferred student loans, must be included as part of the borrowerâ€™s recurring monthly debt obligations. If the borrowerâ€™s credit report does not indicate the monthly amount that will be payable at the end of the deferment period, the lender must obtain copies of the borrowerâ€™s payment letters or forbearance agreements so that a monthly payment amount can be determined and used in calculating the borrowerâ€™s total monthly obligations.
Exception: For a student loan, in lieu of obtaining copies of payment letters or forbearance agreements, the lender can calculate a monthly payment using no less than 2% of the outstanding balance as the borrower's recurring monthly debt obligation. However, if any documentation is provided by the borrower or obtained by the lender that indicates the actual monthly payment, that figure must be used in qualifying the borrower."
Just be certain that your current lender measured you by this standard. Let me know if you have any questions.
