Student Loans and Buying a Home: How Lenders Count Your Payment

Having student loans does not keep you from buying a home, but the way a lender counts them can raise or lower how much you qualify for by a meaningful amount. Lenders add a monthly student loan payment to your other debts to calculate your debt-to-income ratio. If your credit report shows your actual payment, that is usually the number used. If it shows $0, or your loans are in deferment or forbearance, each loan program has its own formula, and the result can be much higher than what you pay today.

Why the student loan number matters so much

Lenders look at your total monthly debts, including the proposed housing payment, as a percentage of your gross monthly income. I explain the full calculation in debt-to-income ratio explained. Every dollar of student loan payment counted against you is a dollar that cannot go toward a mortgage payment. In a high-cost area like Northern Virginia, where buyers are often close to their limit, a few hundred dollars a month can change which neighborhoods or home types are realistic.

How each loan program counts student loans

These are general program rules as published by the agencies. Individual lenders can add stricter rules (called overlays), so always confirm with your loan officer.

Situation	Conventional (Fannie Mae)	FHA	VA
Credit report shows a monthly payment above $0	Use that payment (or the payment on a recent servicer statement if the report is wrong)	Use the reported payment	Use the reported payment if it meets VA’s threshold, or document the actual terms
Income-driven plan with a documented $0 payment	$0 may be used with documentation	0.5% of the outstanding balance	Lender follows VA’s threshold and documentation rules
Deferred or in forbearance	1% of the balance, or a documented fully amortizing payment	0.5% of the outstanding balance	May be excluded if deferred at least 12 months past closing; otherwise a calculated payment
Paid by someone else	May be excluded with 12 months of proof the other party paid on time	Program rules apply; ask lender	Program rules apply; ask lender

The conventional rules above come from Fannie Mae’s Selling Guide section on monthly debt obligations. Freddie Mac, the other major conventional investor, generally uses 0.5% of the balance when no payment is reported, so the same borrower can qualify differently depending on where the loan is sold. FHA rules are in HUD’s single-family handbook, available through HUD. For VA loans, VA guidelines compare the reported payment with a calculated threshold of 5% of the balance divided by 12 and require servicer documentation when the reported payment is lower. My VA loan guide and FHA loan guide cover the rest of those programs.

A worked example (illustrative numbers)

These numbers are illustrative only. Picture a buyer earning $9,000 a month before taxes, with a $400 car payment, a $100 minimum credit card payment and $80,000 in student loans. Assume the lender allows a total debt-to-income ratio of 45%, or $4,050 a month in total debts.

Student loan situation (illustrative)	Payment counted	Room left for housing payment
Credit report shows $350 a month	$350	$3,200
Conventional, documented $0 income-driven payment	$0	$3,550
FHA, reported payment of $0	$400 (0.5% of $80,000)	$3,150
Conventional, loans deferred, 1% rule	$800 (1% of $80,000)	$2,750
Conventional, deferred, documented amortizing payment of $600	$600	$2,950

Same buyer, same income, and the housing budget swings by $800 a month depending on how the loans are documented. At typical rates, that difference can mean well over $100,000 in purchase price. Use our affordability calculator to see what each housing payment buys.

Steps to take before you apply

1. Log in to StudentAid.gov and your servicer’s site. Confirm each loan’s balance, status and current monthly payment.
2. Pull your credit reports and check that each student loan shows the correct payment. Errors here are common.
3. Download a recent servicer statement that shows your payment and plan. Lenders often need it.
4. If your loans are deferred, ask your servicer what the fully amortizing payment would be in writing. It is often lower than 1% of the balance.
5. If any federal loan is in default, talk with your servicer about rehabilitation or consolidation. Government-backed loans generally require defaulted federal debt to be resolved first.
6. Share everything with your lender at the start, then get a full preapproval rather than a quick prequalification. My post on preapproval vs. prequalification explains the difference.

A note on changing repayment plans

Federal student loan repayment has gone through major changes in recent years, including a new Repayment Assistance Plan created by 2025 federal legislation and the phase-out of some older income-driven plans. If you are switching plans, your payment may change, and a lender needs the payment that will actually apply. Time any plan change so you have documentation of the new payment before you go under contract, and ask your loan officer how they will treat a payment that is about to change.

For help that may reduce your cash needs at closing, see our down payment assistance tool. A loan officer or HUD-approved housing counselor can review your specific situation.

Common mistakes I see

• Assuming a $0 income-driven payment will count as $0 on every loan type.
• Not checking the credit report for missing or incorrect student loan payments.
• Choosing a loan program before knowing how it treats your student loans.
• Ignoring a defaulted federal loan, which can stop FHA, VA or USDA financing.
• Paying down a student loan with down payment savings without asking the lender which move improves approval more.
• Changing repayment plans in the middle of the purchase.

Frequently asked questions

Can I buy a house with student loan debt?

Yes. Lenders count a monthly student loan payment in your debt-to-income ratio, but many buyers with student loans qualify. The key is knowing which payment your lender will use.

How do mortgage lenders calculate student loan payments if I’m on an income-driven plan?

For a Fannie Mae conventional loan, a documented $0 income-driven payment can be used as $0. FHA uses 0.5% of the outstanding balance when the reported payment is $0, so the program you choose matters.

Do deferred student loans count against me when buying a house?

Usually yes. Conventional lenders following Fannie Mae use 1% of the balance or a documented fully amortizing payment, and FHA uses 0.5% of the balance. VA may exclude loans deferred at least 12 months past closing.

Can I get an FHA loan if my student loans are in default?

Generally not until the default is resolved, for example through rehabilitation or consolidation. Defaulted federal debt can show up in a federal screening system that FHA, VA and USDA lenders check.
