Can You Get a Mortgage With Student Loan Debt?
Learn how student loan payments factor into mortgage qualification and why the rules for counting them differ between loan programs.
Updated 2026-08-17| Applies to: Borrowers with existing student loan debt who are evaluating how it will affect their mortgage qualification.
The short answer
Student loan debt affects mortgage qualification mainly through your debt-to-income (DTI) ratio, which compares your monthly debts to your gross monthly income. Different loan programs use different rules for calculating the student loan payment counted toward that ratio, especially for loans in deferment, forbearance, or on income-driven repayment plans, so the same student loan balance can affect qualification differently depending on the program.
How do student loans affect debt-to-income ratio?
Debt-to-income ratio, or DTI, is calculated by dividing your total monthly debt payments by your gross monthly income. Student loan payments are included in this calculation just like a car payment or credit card minimum, and a higher DTI can limit the loan amount you qualify for or, in some cases, affect approval altogether.
What if my student loan payment is $0 or very low right now?
This is one of the more program-specific areas of mortgage qualification. Some programs require lenders to use the actual reported payment, even if it's temporarily reduced through an income-driven repayment plan. Others require a calculated percentage of the outstanding balance to be used instead, particularly for loans in deferment or forbearance, or loans without a fixed reported payment. This means two borrowers with the same student loan balance could see different qualifying payments used depending on the loan program.
How different programs may treat student loan payments
| Situation | Common treatment (varies by lender) |
|---|---|
| Fixed monthly payment reported on credit | Actual payment often used |
| Income-driven repayment with low reported payment | Some programs use the reported payment; others use a calculated percentage of balance |
| Loan in deferment or forbearance | A calculated percentage of the balance is often used instead of $0 |
| Loan paid by someone else with proof | May sometimes be excluded from DTI under specific documentation rules |
Can student loans in forbearance still count?
Often yes. Because a $0 payment during forbearance isn't expected to continue indefinitely, most programs require a lender to calculate an estimated payment based on the loan balance rather than using $0, which prevents underestimating a borrower's future obligation.
Does paying down student loans before applying help?
It can help in some cases, particularly if reducing the balance also reduces a calculated payment being used for qualification, or if it lowers your overall DTI. However, it's worth discussing with a loan officer before making large payments, since preserving cash for a down payment and reserves is sometimes more valuable than a modest DTI improvement.
What can borrowers with student loan debt do to prepare?
- Ask a loan officer how your specific student loan servicer and repayment plan will be treated under the program you're considering.
- Pull a copy of your credit report to see what payment is currently being reported.
- Compare how conventional, FHA, and other programs treat your specific repayment plan, since rules can differ.
- Avoid assuming a $0 or very low reported payment will be used as-is for qualification.
- Factor in both current DTI and how future repayment changes, like the end of a deferment period, might affect your budget.
Common mistakes to avoid
- Assuming a $0 reported student loan payment means it won't count toward DTI.
- Not confirming how a specific loan program treats income-driven repayment plans.
- Paying down student loans right before applying without checking whether it actually changes the qualifying payment.
- Not disclosing all student loans, including those not yet in repayment.
- Assuming all lenders calculate the qualifying payment the same way.
