Most guides on this topic say the same thing: student loans raise your debt-to-income ratio, so pay them down. That advice skips the part that actually decides your approval.
Nobody at the lender looks at your $40,000 balance and says no. They look up a monthly number, and each program uses its own formula to produce it. Here is every published formula, what it costs in ten states, and what changes on July 1, 2026.
1. What Underwriters Actually Count
Quick Answer: Underwriters count a monthly payment, never the balance. That payment goes into your debt-to-income ratio alongside your car loan and card minimums. The balance only matters because some formulas calculate the payment as a percentage of it.
Every mortgage decision runs through one arithmetic problem: total monthly debts divided by gross monthly income. Your debt-to-income ratio is the number that has to clear the program’s ceiling.
Student loans enter that equation as a single line item. Three things decide what goes on that line:
- What your credit report says. If a payment above zero is reported, most programs simply use it.
- Whether the reported payment is $0. Deferment, forbearance, and some income-driven plans report zero. That is where the formulas diverge.
- Which program you applied for. FHA, VA, USDA, Fannie Mae, and Freddie Mac each publish their own substitute payment.
No program lets you leave student loans off entirely because the balance is large or the loan is in deferment. Fannie Mae’s guide is explicit that all student debt gets counted. What you can change is the number that gets counted. Send $10,000 against a $50,000 balance that already reports a $340 payment and your ratio does not move. The reported payment is unchanged.

2. How Each Program Counts a $0 Payment
Quick Answer: FHA, USDA and Freddie Mac all use 0.5% of the balance when the credit report shows $0. VA uses 5% of the balance divided by 12. Fannie Mae is the outlier: it lets you qualify with a genuine $0 if you document an income-driven plan.
These rules are published, not negotiable, and easy to check. Here is every formula that governs a mortgage with student loans in 2026. Companies cannot pay for placement in our rankings.
| Program | Payment reported above $0 | Payment reported as $0 | Where the rule is published |
|---|---|---|---|
| FHA | Credit report or documented payment | 0.5% of the outstanding balance | Mortgagee Letter 2021-13 |
| VA | The greater of the reported payment or 5% of balance ÷ 12 | 5% of balance ÷ 12; excluded if deferred 12+ months past closing | VA Circular 26-17-02 |
| USDA | Credit report or documented payment | 0.5% of the outstanding balance | HB-1-3555, Chapter 11 |
| Fannie Mae | Credit report, or the payment on the latest statement | $0 allowed with documented income-driven plan; otherwise 1% of balance or a documented amortizing payment | Selling Guide B3-6-05 |
| Freddie Mac | Credit report or other file documentation | 0.5% of the outstanding balance | Guide Section 5401.2 |
Source: HUD ML 2021-13, VA Circular 26-17-02, USDA HB-1-3555, Fannie Mae B3-6-05, Freddie Mac 5401.2. Compiled by DollarVisor, August 2026.
Two rows deserve a second look. The VA loan program is the only one that can drop student loans to zero without documentation gymnastics, and only when the loan is deferred at least twelve months past closing. Fannie Mae’s $0 route is the single most valuable line in the table, which is exactly why the next few years matter.
3. What the Formula Costs in Your State
Quick Answer: Average federal balances run from $35,014 in Texas to $43,813 in Georgia. Applied to those balances, the formula gap between VA and a deferred conventional loan is $204 a month in Texas and $255 in Georgia.
National averages hide this. The dollar cost of the formula scales with what borrowers in your state actually owe, so the same rule bites harder in Atlanta than in Amarillo.
| State | Average balance | VA (5% ÷ 12) | FHA / USDA / Freddie (0.5%) | Fannie deferred (1%) | Monthly gap |
|---|---|---|---|---|---|
| Georgia | $43,813 | $183 | $219 | $438 |
$255 |
| Florida | $41,162 | $172 | $206 | $412 |
$240 |
| New York | $40,666 | $169 | $203 | $407 |
$238 |
| Illinois | $40,774 | $170 | $204 | $408 |
$238 |
| North Carolina | $40,455 | $169 | $202 | $405 |
$236 |
| California | $39,980 | $167 | $200 | $400 |

4. The Same Borrower, Four Different Price Ceilings
Quick Answer: Hold income, credit and other debts constant and change only the student loan formula. A borrower earning $6,500 a month with a $40,000 balance can support roughly $265,000 of home price on one formula and $219,000 on another, a $45,600 swing.
Here is the math, shown in full. Our borrower earns $6,500 a month before tax, carries a $450 car payment and $150 in card minimums, and has $40,000 in student loans reporting $0. We cap total debts at 45% of income across all four scenarios so the formula is the only thing that moves.
| Scenario | Counted student loan payment | Budget left for housing | Supported home price |
|---|---|---|---|
| Fannie Mae, documented $0 income-driven payment | $0 | $2,325 | $264,900 |
| VA, 5% ÷ 12 | $167 | $2,158 | $245,800 |
| FHA, USDA or Freddie Mac, 0.5% | $200 | $2,125 | $242,100 |
| Fannie Mae, deferred, 1% | $400 | $1,925 | $219,300 |
Illustrative scenario modeled by DollarVisor, August 2026. Assumes 45% total debt ratio, 6.5% fixed rate over 30 years, and taxes, insurance and mortgage insurance at 28% of the housing payment.
Change the rate or the escrow assumption and the dollar figures shift, but the ranking does not. The formula sits between the borrower and roughly $45,600 of purchase price. Your credit score still sets the rate, but the formula sets the ceiling.
The student loan formula is worth more to this borrower than a full point off the mortgage rate.
5. Why the $0 Payment Route Is Closing
Quick Answer: From July 1, 2026, new federal borrowers repay through the Repayment Assistance Plan, which sets a floor of $10 a month. A documented $0 income-driven payment, the one route to a $0 line on a conventional file, stops being available to them.
The Department of Education confirmed that borrowers with new loans get access to two plans from July 1: the Repayment Assistance Plan and a Tiered Standard plan. Payments under the new plan run between 1% and 10% of income, reduced by $50 per dependent, and never fall below $10.
That $10 floor matters more than it looks. Fannie Mae’s friendliest rule needs an income-driven repayment plan that actually produces a $0 payment. A $10 payment is not $0, so the underwriter uses $10, which is still far better than $400, but the guaranteed-zero era is ending.
Two groups are affected differently:
- Borrowers with loans made before July 1, 2026. You have until July 1, 2028 to choose between the new plan, the Tiered Standard plan, or Income-Based Repayment. Existing $0 calculations can still apply in the meantime.
- Anyone borrowing after July 1, 2026. The new plan is the only income-driven option, so $10 is the floor from day one.

6. The FHA Rule Got Four Times Friendlier
Quick Answer: FHA once counted 2% of a deferred student loan balance. It moved to 1% in 2016 and to 0.5% in August 2021. On a $40,000 balance, the counted payment fell from $800 to $200 without the borrower paying a cent.
HUD’s own letter records the history, which is why this table is checkable rather than folklore. It is also the clearest proof that the formula, not the debt, drives the outcome for FHA borrowers.
| Effective | Policy | Formula on a $0 reported payment | Counted payment |
|---|---|---|---|
| 2015 | Handbook 4000.1 as published | 2% of balance | $800 |
| 2016 | ML 2016-08 and ML 2016-10 | Greater of 1% or reported payment | $400 |
| Aug 16, 2021 | ML 2021-13 | 0.5% of balance | $200 |
| 2026 | ML 2021-13 still current | 0.5% of balance | $200 |

7. How to Lower the Payment Lenders Count
Quick Answer: Work the paperwork before you work the balance. Documenting your real payment, or paying off one small loan completely, usually beats sending a lump sum against a large balance that is counted by percentage anyway.
How to reduce the student loan payment on a mortgage application
Run these steps in order, starting at least sixty days before you apply.
- Pull your own credit report first. Find the exact payment each servicer reports. This single line drives everything that follows.
- Get written documentation of your real payment. If your statement shows a lower payment than the credit report, every program will accept the documented figure instead.
- Ask the servicer for an amortizing payment quote. Fannie Mae accepts a documented fully amortizing payment as an alternative to the 1% deferred calculation, and on a long term that quote often lands well below 1%.
- Pay one whole loan off, not a slice of a big one. A balance that is paid in full drops off the file completely. A partial paydown on a percentage-based formula only shaves the percentage.
- Price the file under two programs. Have the loan officer run the same application as conventional and as FHA or VA, then compare the approval, not just the rate. Our breakdown of loan program requirements shows what each one demands.
One popular tip is missing on purpose. Refinancing federal loans with a private lender can cut the payment, but it also ends every income-driven option and the $0 route along with them.
Timing matters too. Servicer updates can take a full billing cycle to reach the bureaus, so paperwork filed the week you apply may not show up in time.
8. When Student Loans Are Not the Real Problem
Quick Answer: A missed student loan payment does more damage than the balance ever will. Delinquency hits your score, and a low score raises your rate or blocks the file entirely, regardless of how the payment is counted.
Student loan balances stood at $1.65 trillion in the second quarter of 2026. The share newly falling 90 days or more behind was 7.83%, down from 12.88% a year earlier, per the New York Fed. Delinquency is easing, but it stays the highest serious-delinquency rate of any consumer debt category.
That is the risk worth managing. Three things sink more of these applications than the DTI formula:
- A recent late payment. Ninety days past due on a student loan reads the same to underwriting as any other major derogatory entry.
- Default status. A federal loan in default triggers CAIVRS screening and blocks FHA, VA and USDA financing until it is resolved. Our guide on what happens when you default on student loans covers the exit routes.
- A thin file. Student loans alone rarely give an underwriter enough history. Two or three seasoned tradelines matter more than a smaller balance.
Other derogatory entries stack on top of this. If your file also carries a charge-off, a judgment or a past foreclosure, those clocks run alongside the student loan math rather than replacing it.
9. The Verdict on a Mortgage With Student Loans
Quick Answer: You can buy with student loans, and no program imposes a waiting period for having them. Choose the program by how it counts your payment, document the smallest legitimate figure, and keep every account current.
Our read: the borrowers who struggle here are almost never the ones with the biggest balances. They are the ones who applied to a single lender, accepted the first formula they were handed, and never learned that four other formulas existed.
Three moves, in order of value:
- Document your payment before you apply. The written figure beats the credit report figure whenever it is lower.
- Compare programs on approval, not rate. A quarter point saved is worth less than the right qualifying formula.
- Fix delinquency first. Nothing in this article helps a file that is ninety days late. Learn more about how DollarVisor compares money decisions before you commit.
Other marks on your file run their own clocks. Read our companion pieces on buying a house with a charge-off, on qualifying for a mortgage with a judgment, and on the waiting periods that follow a foreclosure.
10. Frequently Asked Questions
1. Can you get a mortgage with student loans?
Yes. No loan program sets a waiting period or a balance limit for student debt. The loans are counted as a monthly payment inside your debt-to-income ratio, and every program publishes a formula for that payment. Approval depends on whether the resulting ratio clears the program’s ceiling, not on the size of the balance.
2. Do deferred student loans count against a mortgage?
Almost always. Fannie Mae uses 1% of the balance for deferred loans, while FHA, USDA and Freddie Mac use 0.5%. The one exception is VA financing, which lets the lender skip the payment when the loan is deferred at least twelve months beyond the closing date.
3. Will a $0 income-driven payment be accepted?
Only by Fannie Mae. Its Selling Guide permits qualifying with a $0 payment when documentation from the servicer verifies the income-driven amount is genuinely zero. FHA, USDA and Freddie Mac replace the zero with 0.5% of the balance no matter what the plan says.
4. Should I pay off student loans before buying a house?
Usually not in full. Paying a single small loan to zero removes it from the file entirely, which helps. Sending a lump sum against a large balance only reduces a percentage-based payment slightly, and the same cash used as a down payment normally buys more approval room.
5. How does the new Repayment Assistance Plan affect mortgage approval?
It sets a $10 monthly floor, so genuinely zero payments end for borrowers on it. Payments run from 1% to 10% of income, less $50 per dependent. For most applicants the counted payment stays far below the 1% deferred calculation, so the practical effect on approval is small.
