Student debt and a mortgage: it's possible
Having student debt doesn't mean you can't buy a home. It does mean you'll typically be able to borrow somewhat less than someone without debt. Mortgage lenders look at what you pay each month to DUO (the Dutch student loan agency) and count that as a fixed monthly obligation. The lower that monthly payment, the more you can borrow for your mortgage.
Good preparation makes all the difference. If you know exactly where you stand, you can plan smartly and sometimes borrow more than you'd expect.
How does your student debt factor in?
Since 1 January 2024, mortgage lenders can base their calculation on the actual monthly payment DUO has set for your student debt, rather than the original loan amount. How high that monthly payment is depends partly on the loan system under which you studied:
Old loan system (before 1 Sept 2015)
15-year repayment term. Because of the shorter term, the monthly payment is higher, which has more impact on your maximum mortgage.
New loan system (after 1 Sept 2015)
35-year repayment term. The monthly payment is lower because the debt is repaid over a longer period. That's relatively favorable for your mortgage.
The legally required monthly payment on your student debt is converted by the lender into a gross monthly amount. Based on that, they determine how much impact your DUO debt has on your maximum mortgage. The higher the mortgage interest rate, the bigger this conversion effect. Your mortgage adviser can calculate this precisely for you.
What does this mean for your mortgage in practice?
Say you have € 20,000 in student debt. For the mortgage calculation, the lender doesn't look at the amount you personally repay to DUO each month, but at the statutory monthly payment that applies to your student debt. Based on that, they calculate how much your student debt affects your maximum mortgage. Depending on your income, the mortgage interest rate, and the lender's conditions, this can mean you're able to borrow less.
The good news is that your student debt keeps decreasing over time. The lower the remaining debt, the smaller its impact on your maximum mortgage.
Handling your student debt smartly for your mortgage
- Check your current debt with DUO
Log in to Mijn DUO and check your current outstanding debt and monthly payment. This is the amount the lender uses in its calculation. - Consider extra repayments
Making extra repayments lowers your monthly payment to DUO, which may let you borrow more. Afterwards, always request an updated monthly statement from DUO, otherwise the bank will use the old amount. - Always report your debt honestly
Student debt isn't registered with BKR (the Dutch credit registration agency), but lenders find out through your bank statements. Hiding it is considered fraud and can cost you your NHG (National Mortgage Guarantee) protection. Honesty prevents problems later on. - Have everything calculated by an adviser
We put your income, student debt, housing wishes, and future plans side by side and show you exactly what you can borrow. No surprises afterwards.
Student debt and the National Mortgage Guarantee (NHG)
Want a mortgage with National Mortgage Guarantee (NHG) (in Dutch)? Then it's especially important to report your student debt honestly. NHG offers protection if you have to sell your home at a loss, for example after job loss or divorce. If you've concealed your student debt, that protection no longer applies.
In 2026, the NHG limit is € 470,000 (€ 498,200 if the home is fully energy-efficient). We calculate whether NHG is advantageous for you and whether it's feasible alongside your student debt.
Frequently asked questions about student debt and mortgages
How much less can I borrow with student debt?
That depends on your monthly payment to DUO and your income. Student debt of € 20,000 can lower your maximum mortgage by € 20,000 to € 38,000. An adviser can calculate the exact figure for your situation.
Do I have to declare my student debt when applying for a mortgage?
Yes. Student debt isn't registered with BKR, but you're required to report it honestly. Lenders can see DUO payments on your bank statements. Concealing it is considered fraud and can have serious consequences, including for your NHG eligibility.
Does paying off extra on my student debt help me get a higher mortgage?
Yes, but only if you also request an updated monthly statement from DUO afterwards. The lender calculates using the officially registered monthly payment, so make sure this is in order well before you submit your mortgage application.
Does my partner's student debt count too?
Yes. For a joint mortgage application, both partners' student debts are included in the calculation of your maximum mortgage. We map everything out clearly together during an advice call.
Can I buy a home if I haven't started repaying yet?
Yes, that's possible. Even if you haven't started repaying yet, the lender takes into account the future monthly payment that applies to your debt. We calculate what's feasible for your situation.
