Every mortgage lender will determine their own policies, but most mortgage lenders will follow the guidelines of the specific loan program you are applying for (conventional Fannie Mae or Freddie Mac, FHA, VA, or USDA). What matters most is how the lender counts your student loan payment in your debt-to-income (DTI) ratio.
How the monthly payment is counted
- Conventional (Fannie Mae / Freddie Mac): generally uses the actual payment on your credit report, including a $0 IDR payment when it’s documented. If no payment is showing, they may use a small percentage of the balance.
- FHA: historically counted a percentage of the balance even when your real payment was $0 — though the rules have moved toward using the actual documented payment. Confirm the current guideline with your lender.
- VA and USDA: each have their own formulas; ask your lender which one applies.
What you can do
- Get a recent statement showing your actual monthly payment (including $0 IDR payments).
- Ask the lender up front which program guideline they’ll use to count your student loans.
- If your DTI is tight, compare lenders — the way they count the payment can change how much home you qualify for.
The takeaway: your student loans don’t automatically block a mortgage, but the payment amount a lender uses can make a real difference. Know the guideline before you apply.
