Buying a Home With Student Loans: How Lenders Count IDR and RAP Payments in Your DTI
Student loans don't disqualify you from buying a home, but how lenders count them varies a lot by loan type. Here is what each program uses, why a $0 payment can backfire and how the new RAP plan changes the math.

How we check numbers →
Lenders count a student loan payment in your debt-to-income ratio even if you pay $0. Fannie Mae can accept a documented $0 income-driven payment; FHA, Freddie Mac and USDA substitute 0.5% of your balance when the payment is $0. A small documented payment, like the Repayment Assistance Plan's $10 minimum, is usually counted as-is, which can beat the balance formulas.
Numbers That Matter
| Rule | What it says | Source | Verified |
|---|---|---|---|
| Fannie Mae, income-driven plans | A documented $0 income-driven payment can be used; deferred loans use 1% of the balance or a documented amortizing payment | Fannie Mae Selling Guide B3-6-05 | Sep 28, 2026 |
| FHA | Uses the actual payment if above $0; otherwise 0.5% of the outstanding balance | HUD Mortgagee Letter 2021-13 | Sep 28, 2026 |
| Repayment Assistance Plan (from July 1, 2026) | Payments based on income, never below $10 a month | P.L. 119-21 | Sep 28, 2026 |
| Debt-to-income basics | How lenders weigh your debts against income | CFPB | Sep 28, 2026 |

How Each Loan Type Counts Your Student Loans
| Loan type | Documented payment above $0 | $0 income-driven payment |
|---|---|---|
| Fannie Mae (conventional) | Actual payment | $0 allowed with servicer documentation |
| Freddie Mac (conventional) | Actual payment | 0.5% of the balance |
| FHA | Actual payment | 0.5% of the balance |
| USDA | Actual payment | 0.5% of the balance |
| VA | Rules differ; loans deferred 12+ months past closing can be excluded, otherwise a balance-based or documented payment | Depends on VA's method; ask your lender |

What the Repayment Assistance Plan Changes
The new Repayment Assistance Plan, available from July 1, 2026, sets payments by income with a $10 monthly minimum. Because that payment is never $0, lenders that substitute 0.5% of your balance for a $0 payment should generally be able to count the actual documented RAP payment instead. For borrowers with large balances and modest incomes, that can make a real difference in how much house they qualify for.
Steps Before You Apply
- Get a servicer statement showing your current required payment, plan and balance.
- Make sure your credit report matches; if it shows a higher payment, the lender will need your statement.
- Compare loan programs: a $0 payment helps most with Fannie Mae; a small payment helps everywhere.
- Avoid deferment or forbearance right before applying, which can trigger the balance-based formulas.
- Pay down other debts if you're close to the lender's DTI limit.
Worked Example: $60,000 of Student Loans
- On RAP: with $45,000 of AGI, the payment is about $150 a month, counted as-is.
- If the payment showed $0: FHA, Freddie Mac and USDA would count 0.5% of the balance, $300; Fannie Mae's deferred-loan rule could count 1%, $600.
- The difference: $150 a month is about 2.5 points of DTI on $6,000 of monthly income, room for about $22,868 more mortgage at 6.86%.
RAP payment computed from the plan's income brackets for a single borrower with no dependents; your figures will differ.
Decision Rules
If this, then that
- If your documented payment is $0 → compare a Fannie Mae conventional loan first.
- If you're on RAP → document your actual payment; it's usually better than 0.5% of your balance.
- If your loans are in deferment → consider entering repayment before applying.
- If you're near your DTI limit → pay down a car loan or card before touching student loans.
- If forgiveness is close → ask whether your lender can exclude loans near discharge.
Mistakes to avoid
- Assuming a $0 payment means lenders ignore your student loans.
- Letting your credit report show a higher payment than you owe.
- Entering forbearance right before applying.
- Applying with one program without comparing the others.
- Forgetting to bring a current servicer statement.
