Student Loans and Mortgage Qualification

How student loans are counted in DTI

The monthly payment used for DTI calculation depends on the loan program and your repayment status. The rules have changed significantly in recent years — particularly for borrowers on income-driven repayment (IDR) plans.

• Conventional (Fannie Mae): Uses the actual monthly payment if greater than zero. If the loan is deferred or in forbearance, uses 1% of the outstanding balance as the monthly payment.
• Conventional (Freddie Mac): Uses the actual monthly payment. If deferred, uses 0.5% of the outstanding balance.
• FHA: Uses the greater of the actual payment or 0.5% of the outstanding balance. IBR payments of $0 are not accepted — FHA uses 0.5% of the balance in that case.
• VA: Uses the actual monthly payment. If deferred for 12+ months from the closing date, the payment can be excluded from DTI entirely.
• USDA: Uses 0.5% of the outstanding balance if the actual payment is not available or is $0.

Income-driven repayment (IBR) and $0 payments

Borrowers on income-driven repayment plans (IBR, PAYE, SAVE) may have a $0 monthly payment. For conventional loans, a $0 IBR payment is used as-is in the DTI calculation — which can significantly help qualification. For FHA, a $0 IBR payment is replaced with 0.5% of the balance, which can be a meaningful DTI hit for borrowers with large student loan balances.

This difference in treatment is one reason some borrowers with large student loan balances qualify more easily for conventional loans than FHA, even though FHA has more flexible credit requirements.

Public Service Loan Forgiveness (PSLF)

Borrowers pursuing PSLF (teachers, government employees, nonprofit workers) are typically on IDR plans with low or $0 payments. The forgiveness itself doesn't affect mortgage qualification — what matters is the current monthly payment. If you're on an IDR plan with a documented payment, that payment is used in the DTI calculation for conventional loans.
