How Student Loans Count When You Apply for a Mortgage

October 23, 2026•5 min read

Here is the thing nobody tells you about student loans and buying a house. The payment on your credit report may not be the payment the underwriter uses. Sometimes a zero turns into a real number. And which number counts depends on the type of loan you apply for.

That one detail can swing what you qualify for, so let's take it in baby steps.

Why do student loans matter so much in a mortgage approval?

Debt to income. That is your monthly debts plus the new house payment, divided by your gross monthly income. Every student loan counts, even the ones you are not paying right now. A bigger student loan number leaves less room for the house.

My credit report shows a zero payment. Doesn't that mean it counts as zero?

Not necessarily. Income-driven plans can carry a legitimately low or zero payment, and deferred loans often report zero too. As of October 2026, here is the general picture from each agency's own guide:

  • Conventional, Fannie Mae: If documentation shows your income-driven payment really is zero, Fannie Mae's Selling Guide lets the lender qualify you at zero. For loans in deferment or forbearance, the lender uses either one percent of the balance or a fully amortizing payment based on the documented terms.

  • Conventional, Freddie Mac: Freddie Mac will not count a student loan at zero. When the credit report shows zero, its guide generally has the lender use half of one percent of the outstanding balance, unless other documentation supports a different payment above zero.

  • FHA: Under HUD's rule from Mortgagee Letter 2021-13, the lender uses the reported or documented payment when it is above zero, and half of one percent of the outstanding balance when the credit report shows zero.

  • VA: The VA Lender's Handbook lets a loan be left out if you have written proof it is deferred at least 12 months past closing. Otherwise the lender compares the credit report payment to five percent of the balance divided by 12 and uses the higher one, unless a current servicer statement documents a lower actual payment.

Same borrower, same loans, four different qualifying numbers. Nobody should guess at this.

Why would the underwriter use a different number than my credit report?

Credit reports lag. If you just switched plans or recertified your income, the report may still show the old number. Some servicers report zero during a deferment even though a real payment is coming. And the underwriter is asking one question: what will you actually owe after closing? A zero that becomes a real payment a few months after you move in is exactly the hidden wall these rules are built to catch.

Federal repayment plans also got reshuffled this year, with the SAVE plan winding down and the new Repayment Assistance Plan opening July 1, 2026, as widely reported this summer. If your plan moved, your paperwork may lag.

So which loan type is better for me?

That depends on your whole file: credit, down payment, the property, your income. But the student loan math often tips it. A large balance on a documented zero income-driven payment can look very different on a Fannie Mae conventional loan than on FHA. Loans deferred well past closing can open room for a VA eligible buyer that nobody else in the comparison has. As a broker, I can run the same file against different programs and loan types instead of forcing it through one door.

What should you bring so the right number gets used?

  • Your most recent statement from each student loan servicer, showing the balance, the payment, and the plan.

  • If you are on an income-driven plan, the letter or online screen showing your current payment and when you recertify next.

  • If you are deferred, written proof of the deferment and the date it ends.

Download them before you apply, not after the underwriter asks. Swallow the frog early.

Should you change your student loans before you buy?

Maybe. Sometimes paying off one small loan removes a payment and opens room. Sometimes that cash does more as down payment or reserves. Do not drain your savings on a hunch. Let's run it both ways first. And do not switch plans or consolidate mid-mortgage without talking to me, because a payment that moves mid-file means new documents and fresh questions.

Guidelines change and every file is different, so treat this as general education, not advice for your specific situation.
