Not sure what you mean by "offered". But with any Fannie Mae loan, student loan payments need to be included in the debt to income ratio regardless if they are in deferment or not.
Deferred Installment Debt
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.
