Student loans usually count in the debt-to-income ratio (DTI), which compares monthly debt with qualifying monthly income. The amount depends on the conventional program and the records you provide. A documented $0 income-driven payment can count as $0 under Fannie Mae's rule. Freddie Mac may require a calculated payment when the documented payment is $0 or missing.
Key takeaways
- Give your lender the latest student-loan statement and income-driven repayment notice, if applicable.
- Fannie Mae accepts a documented $0 income-driven payment for its DTI calculation.
- For certain deferred or undocumented loans, published program rules use a balance-based or documented amortizing payment. Ask which program the lender is using.
How do Fannie Mae and Freddie Mac treat student loans?
Conventional loans can follow different investor rules. Fannie Mae's guide can use the documented income-driven payment, even when that payment is $0. If payments are on hold, Fannie Mae generally uses 1% of the balance. A documented payment that would pay off the loan on schedule may also meet its rule.
Freddie Mac's guidance uses 0.5% of the outstanding balance when the payment is $0 or no payment is documented. Other payment situations have separate rules. Your lender's review and the current program guide control the final calculation.
| Student-loan record | Fannie Mae | Freddie Mac |
|---|---|---|
| Documented income-driven payment above $0 | Use the documented payment under the guide. | Use the qualifying payment under Freddie's rules. |
| Documented income-driven payment of $0 | May use $0. | Generally use 0.5% of the outstanding balance when $0 is reported. |
| Deferred or no payment documented | Generally use 1% of balance or a documented fully amortizing payment under the guide. | Generally use 0.5% of the outstanding balance when no payment is reported. |
Which documents should you bring?
Start with a simple list of every student loan. Log in to each account and save a recent statement. Check the balance, payment, and date. If a loan moved to a new company, get its new statement. Give the lender the same records you used to make your list. Ask which monthly amount it used for each loan. Keep its answer with your papers.
- Current statement for every student loan, with balance, required payment, and status.
- Your income-driven repayment approval or renewal notice if the payment is based on income.
- Written servicer evidence if a loan is deferred, in forbearance, or paid by another party.
Do not assume a credit report shows the correct current payment. If the report says $0 but a new repayment amount has begun, tell the lender and provide the updated record. If a payment changes during the mortgage process, the file may need a new DTI calculation.
Why does the program choice matter?
Suppose a student-loan balance is $20,000 and the documented income-driven payment is $0. Under Fannie Mae's stated rule, that documented payment may enter the DTI as $0. Under Freddie Mac's stated $0-payment rule, 0.5% of the balance would be $100 per month. This example shows a calculation difference, not a mortgage approval or loan offer.
For the wider file, see Nevada conventional loan requirements and our learning center. Ask your lender to name the investor rule used on your application.
Why does the student-loan amount matter to mortgage DTI?
Debt-to-income ratio, or DTI, compares certain monthly debt obligations with qualifying monthly income. It is one part of a conventional mortgage review. A student-loan balance is not itself the monthly amount in that calculation. The lender must decide which monthly payment to count under the program's rules.
That number can differ from the payment on a credit report or the amount currently being drafted from your bank account.
The distinction becomes important when a loan is deferred, in forbearance, or in an income-driven repayment plan. A statement may show no current bill while a balance remains. The loan has not vanished. Fannie Mae and Freddie Mac publish different instructions for several of these situations.
A lender also has to verify which agency or investor rule applies to the particular mortgage file. Some lenders may have additional requirements, commonly called overlays.
Ask a simple question at the start: "What monthly student-loan amount will you use for each account, and which program rule supports it?" Request a written breakdown if there are several loans. Compare that breakdown with the most recent statements.
This is more useful than guessing from a generic online DTI calculator. A calculator cannot see the repayment plan, current statement, or investor rule attached to your application.
Do not pay down or change a student loan solely because an online chart suggests a different DTI. First ask the mortgage lender how it will document the debt and whether a proposed change would alter the qualifying calculation.
The Fannie Mae Selling Guide and Freddie Mac Guide are the primary rule sources. But your lender must apply the right one to your file.
What should you check on every student-loan account?
Make a list of every loan, even if several share one servicer. For each account, note the current balance, required payment, repayment status, and the date the information was issued. A recent servicer statement is more useful than a screen showing only the total balance.
If you use income-driven repayment, save the plan approval or renewal notice that shows the required amount and effective period.
Compare the statement with your credit report. Credit data can lag after a repayment-plan change, transfer to a new servicer, or the end of deferment. A zero shown on the report may describe old information.
Fannie Mae's guide permits a lender to use a more recent student-loan statement to document an accurate payment instead of a stale credit-report amount. The lender must still keep the required evidence in the file. Ask how it will handle a mismatch; do not hide it.
If you have multiple loans under one repayment plan, check whether the plan notice states a combined amount or assigns an amount to each loan. The lender needs a consistent method that avoids counting a single obligation twice or leaving a loan out.
Ask the servicer for a fuller statement if the portal view is unclear. Keep the correspondence so the mortgage reviewer can see where the figures came from.
For a loan that someone else pays, bring proof rather than a verbal explanation. Agency rules may allow an exclusion in specific third-party-payment situations. But there are documentation and history conditions. It is not a universal exception for a parent, spouse, or employer who offers to help.
Ask the lender to review the exact account and current agency rule before removing anything from the DTI list.
What does a documented income-driven payment of zero mean?
Income-driven repayment, often shortened to IDR, ties the required student-loan payment to an approved plan and the borrower's income. A current approved plan can show a required payment of zero.
Under Fannie Mae's published rule, a properly documented zero IDR payment may be counted as zero for the student-loan portion of DTI. The lender needs the documentation; a zero printed on a credit report by itself is not enough to assume the IDR rule applies.
Freddie Mac handles a reported zero differently under its guidance. When no monthly payment is reported or the reported payment is zero, it generally uses a calculated amount based on the outstanding balance.
That is why two conventional reviews can use different DTI figures for the same student-loan account. The result does not mean one agency is "better" for every borrower. The whole mortgage file, program eligibility, and lender review still matter.
An IDR amount can change after a plan renewal or income update. Federal Student Aid explains that borrowers generally must recertify income and family size for IDR plans. Save the current notice and note its renewal date.
Tell the mortgage lender if the required amount changes while the application is in progress. Do not represent a temporary zero as a permanent student-loan cancellation. The debt remains unless the servicer confirms another event.
See Federal Student Aid's IDR overview for the plan process.
If a lender says it cannot use your documented IDR amount, ask it to identify the investor rule and any lender-specific requirement. A clear answer lets you compare the actual program choices available to you. It also prevents a useful document from being overlooked in a rushed file review.
How are deferment and forbearance different from repayment?
Deferment and forbearance can temporarily change what a student-loan servicer requires you to pay. They do not ordinarily erase the balance. Mortgage underwriting looks ahead to the obligation rather than assuming a pause will last forever. The rules therefore may use a calculated monthly amount even when the current statement says no payment is due.
For Fannie Mae, the published rule for a deferred student loan or a loan in forbearance with no documented payment generally calls for one percent of the outstanding balance, or a fully amortizing payment documented under the guide.
"Fully amortizing" means a payment schedule designed to pay the balance over its term. The lender determines which documented figure satisfies the rule. Do not use a random calculator figure in place of the required servicer evidence.
Freddie Mac's guidance generally uses one-half percent of the outstanding balance when the payment is zero or no payment is reported. The lender still has to follow the current Guide and verify the actual loan facts. A nonzero required payment may be handled differently. So do not apply the zero-payment formula to every student-loan account.
If a pause is about to end, get the latest notice from the servicer. The future scheduled payment may be available and relevant. Give the lender the new document before it relies on an old credit report. If several loans have different end dates, list them separately.
An accurate file may take a little more preparation. But it is better than having an underwriting change late in the purchase process.
Worked examples of different documented situations
Documented zero IDR: Suppose one student loan has a $40,000 balance and a current approval letter confirms a required IDR payment of zero. Fannie Mae's IDR rule may allow zero in the DTI calculation.
Freddie Mac's zero-payment guidance generally calls for one-half percent of the balance, or $200 per month, if that program applies. These are student-debt underwriting figures only. They do not predict mortgage approval, a mortgage payment, or the best program for that borrower.
Deferred account: Assume the same $40,000 balance is deferred and there is no documented payment. Fannie Mae's one-percent route would produce $400 per month, unless a qualifying documented fully amortizing payment is used under its guide.
Freddie Mac's one-half-percent route would produce $200 per month when its zero/no-payment rule applies. The lender must check the actual status and current documentation. A deferred status is not an instruction to leave the debt out.
Outdated credit report: A report shows a required amount that differs from the current servicer statement after a plan change. Bring the new statement and plan notice. Ask which amount the lender can document under the applicable agency rule. Do not assume the smallest figure wins.
The correct figure is the one supported by the facts and the program's instructions.
These examples isolate one student loan to explain the rule. Real DTI also includes other counted debts and the lender's qualifying income calculation. A small change in one monthly debt amount may or may not change a loan decision. Use the examples to ask precise questions, not to self-certify eligibility.
What if someone else makes the student-loan payments?
Third-party payment is a common source of confusion. A parent may pay a graduate's loan, a former spouse may send funds, or an employer may provide assistance. The student loan can still be the borrower's legal obligation. It should be disclosed on the mortgage application.
A person making payments for you is not the same as the debt being removed from your name.
Fannie Mae has a conditional rule that can permit certain nonmortgage debts, including student loans, to be excluded when another party has made the payments for a documented period and the other requirements are met.
The guide requires evidence, commonly including a 12-month payment history from the third party. There are details about the debt and any delinquency. The lender must apply the full current rule, not just the phrase "someone else pays."
Ask the payer for records through a safe method if you want the lender to review this possibility. The records should identify the account, amounts, dates, and source of payments. Also ask whether the payer's role creates any other documentation issue.
Do not ask someone to start paying for one month and expect that to substitute for the required history.
Freddie Mac and individual lenders may not apply the same exclusion in the same way. Ask which conventional program the file follows and whether that program allows the treatment. If the debt remains in DTI, the lender can still review the entire file.
The point of asking is to use a documented rule where it truly applies, not to conceal a liability.
How can a buyer prepare before requesting preapproval?
First, obtain recent statements for all student loans and the current IDR notice, if applicable. Make a simple list with account name, balance, required amount, and status. Note whether the account recently moved to a new servicer.
If you are unsure whether a statement shows one loan or several, ask the servicer for a breakdown. Keep the original PDF rather than relying only on a phone screenshot.
Second, review your credit report for each loan. Look for missing accounts, duplicate entries after a transfer, and old payment figures. A credit-report issue and a student-servicer issue are different. Bring both records to the mortgage lender so it can decide what documentation it needs. Do not dispute an accurate account just to change a mortgage calculation.
Third, ask the lender to estimate DTI under the specific conventional program it expects to use. Request a per-loan explanation. If the file might be evaluated under Fannie Mae or Freddie Mac rules, ask how the results differ for your documented status.
A lender may have other reasons to choose a program. So focus on the complete offer and qualification review rather than one debt formula.
Fourth, keep watching for changes. IDR renewal, the end of deferment, or a servicer correction can change the required amount. Send new records before final underwriting. An early update is easier to address than a surprise just before closing. Our Nevada conventional preparation guide covers the rest of the application documents.
How should you read a DTI explanation from a lender?
A useful explanation names the student-loan account, current status, source document, program rule, and monthly amount used. If any part is missing, ask.
For example: "Is this figure from my current statement, the credit report, or a balance-based agency formula?" If there are two similar loans, confirm the lender did not count one twice.
If a loan is paid off, bring a payoff statement rather than assuming the credit report has updated.
Separate what the servicer bills from what underwriting counts. A lender may count a calculated amount during a student-loan pause even though the servicer currently bills nothing. That is not an extra student-loan charge imposed by the mortgage lender. It is a qualifying assumption under the mortgage program.
Ask how the assumption would change if you document a required payment later.
Then ask how the student-loan amount interacts with the wider file. DTI uses qualifying income and other counted debts. A balance-based student-loan amount may be important for one borrower and immaterial for another. The lender should explain any remaining conditions without promising approval from a single ratio.
Our learning center has broader conventional-loan topics if you need to review the rest of the process.
Keep the written explanation with the records you supplied. If a later review uses a different monthly figure, you can ask what changed. Was the program different? Did the repayment status change? Did a new statement arrive? A clear trail prevents confusion between a rule change and a document correction.
What if loans were consolidated, transferred, or paid off?
A consolidation can replace several old loans with one new loan. Credit reports may show both the closed accounts and the new account for a while. Bring the consolidation notice and a current statement so the mortgage reviewer can identify what is still owed.
Do not assume an old line is an active second debt, and do not assume it will disappear from underwriting without proof.
A servicer transfer can create a similar puzzle. The company collecting the student loan changes. But the debt may be the same. Keep the transfer notice, the final statement from the old servicer, and the first statement from the new one.
If the required payment changed at the same time, ask the new servicer for an official record of the amount and effective date. The lender can then reconcile the report with the current account.
If a loan was paid off, ask for a payoff or zero-balance letter that identifies the account. A bank transfer alone does not prove how the servicer applied the funds.
If the account is still shown as active on a credit report, give the lender both the report and the servicer evidence. The lender will decide whether its program permits removing the obligation before the credit bureau updates.
These situations are about getting an accurate debt list. They are not reasons to omit a loan from the application. Tell the lender about each account and document what happened. A complete, traceable list makes the final DTI explanation easier to understand and reduces late corrections.
Common student-loan questions to ask your mortgage lender
"Does a zero on my credit report count as zero?" Not automatically. A documented income-driven zero can be eligible under Fannie Mae's rule. Freddie Mac generally uses a balance-based amount for a reported zero. The lender must determine which program and documentation apply.
"Can I ignore a deferred loan?" No. Disclose the account. A pause in collection is not the same as eliminating the debt. Ask the lender which monthly figure the current guide requires.
"Should I switch repayment plans during the mortgage process?" Ask both your student-loan servicer and mortgage lender before making a change. A plan change can affect future student obligations and the mortgage documents needed. This guide cannot determine which student-loan plan is right for you.
"Will a zero IDR amount stay zero forever?" Do not assume that. Income-driven plans are reviewed and may change. Keep the current approval and renewal date in the file.
"Can I choose Fannie Mae because its IDR rule looks better?" A lender can discuss program paths. But agency eligibility, lender rules, the rest of the application, and the available loan terms all matter. One student-loan rule does not determine the entire mortgage choice.
Common questions
Can I use an old statement?
Try to get a recent one. A loan balance or payment can change. Ask the lender when it needs a new statement. Save the new copy with your other papers.
Is this the same as student-loan forgiveness?
No. These rules only tell the lender what monthly debt to use. They do not change what you owe the student-loan company.
Can I leave student loans off the application if they are deferred?
No. Disclose the debt. The lender determines the qualifying amount under the program rules.
Will a $0 income-driven payment always count as $0?
No. Fannie Mae's documented income-driven rule allows it, while Freddie Mac's published guidance can require a balance-based amount.
