Buying a house with student loans: how lenders count the payment

Student loans do not stop you from buying a home, but they change the math. The key question is which monthly payment the lender counts, because a deferred loan or a $0 income-driven payment can still add hundreds of dollars to your debt-to-income ratio on paper.

Student loan debt is common among first-time buyers, and it rarely rules anyone out on its own. It does shape how much you can borrow, because lenders add a monthly student loan payment to your other debts when they work out your debt-to-income ratio. The surprise for many buyers is that the payment a lender counts can be different from the payment they actually make.

Why the counted payment matters

Lenders compare your monthly debts with your gross monthly income. Fannie Mae's Selling Guide caps the total ratio at 36 percent for manually underwritten loans, up to 45 percent with strong credit and reserves, and 50 percent for loans approved through its automated system. Every $100 of counted student loan payment uses up part of that room. On a $6,000 monthly income, $100 is 1.7 percentage points of ratio.

How Fannie Mae counts student loans

Fannie Mae's rules start with the credit report. If it shows a monthly payment, the lender may use it. If that figure is wrong, the lender may use the payment on your most recent student loan statement.

When the credit report shows no payment or $0, the lender picks a method:

Income-driven plan with a $0 payment. If your student loan documents verify that the actual payment is $0, the lender may qualify you with $0.
Deferred or in forbearance. The lender may count 1 percent of the outstanding balance, or a fully amortizing payment using the documented repayment terms.

How FHA counts student loans

HUD's Handbook 4000.1 requires FHA lenders to include every student loan, whatever its status. The lender uses the payment on the credit report or the actual documented payment when it is above zero. When the reported payment is zero, the lender must use 0.5 percent of the outstanding balance. FHA does not accept a $0 payment, even on an income-driven plan.

The handbook also lets the lender leave a loan out when written documentation shows it has been forgiven, canceled, discharged or paid in full.

Ways to lower the counted payment

Get the real payment on paper. If you are in repayment, a statement showing the actual payment may let the lender use it instead of a percentage of the balance.

Check the credit report. A wrong balance or payment can inflate the counted figure. The CFPB's student loan resources explain how to reach your servicer and fix problems.

Compare programs. As the example shows, the same loan can count differently under Fannie Mae and FHA. A loan officer can show you both.

Pay down other debt. A credit card or car payment counts in full. Removing one can make room for the student loan.

Ask before you change plans. Switching repayment plans changes the documented payment. Talk to your servicer and your lender before you make a change in the middle of a mortgage application.

Keep the real budget in view

Qualifying is not the same as being comfortable. If your loan is deferred today, plan for the payment you will owe when deferment ends. Add it to your monthly budget alongside the full housing payment, and keep an emergency fund. The true monthly cost guide shows how to build that budget.

The bottom line

Student loans count in your debt-to-income ratio, and the counted payment depends on the program. Fannie Mae can use a documented $0 income-driven payment or 1 percent of a deferred balance. FHA uses the reported payment or 0.5 percent of the balance. Ask your lender which rule applies, and run the numbers before you shop.

Questions buyers ask

Can I get a mortgage with student loans?

Yes. Student loans count as a debt like any other. What matters is the monthly payment the lender uses, your income and your other debts, which together set your debt-to-income ratio.

How does Fannie Mae count a deferred student loan?

Fannie Mae's Selling Guide lets the lender use 1 percent of the outstanding balance as the monthly payment for loans in deferment or forbearance, or a fully amortizing payment based on the documented repayment terms.

What if my income-driven payment is $0?

Fannie Mae allows the lender to qualify you with a $0 payment if your student loan documents verify that the actual payment is $0. FHA does not: when the reported payment is zero, HUD's handbook requires 0.5 percent of the balance.

Do VA and USDA loans count student loans the same way?

Each program has its own rules, and lenders can add their own. Ask the lender which method applies to your loan before you compare offers.
