Getting a Belgian mortgage as a foreigner
10 min read · Updated 9 September 2026
Key points
No law stops a foreigner borrowing in Belgium, but lending is a commercial decision and banks apply their own policies. Three things decide your file: the stability of your income, how much of your own money you bring, and how long your right to stay runs. Nationality itself matters far less than newcomers expect; a permanent contract and a five-year residence permit will open more doors than an EU passport with a probation period.
Who can borrow
Every Belgian lender sets its own acceptance policy, and none publishes it. From how files are assessed in practice, three profiles emerge:
- Resident with a Belgian income and a permanent contract. Treated exactly like a Belgian national, whatever the passport. This is the case for most expats after a year or two.
- Resident with a fixed-term contract, probation, or self-employment. Possible, but expect to be asked for more own funds and more history — typically two to three years of accounts if you are self-employed.
- Non-resident, or income earned entirely abroad. The hardest case. Several major banks simply decline; those that accept usually want a substantially lower loan-to-value.
What almost never blocks a file on its own: being non-EU, having arrived recently, or not speaking French or Dutch. What does block files: irregular income, an unexpired probation period, and existing credit commitments abroad that you did not declare.
Loan-to-value: the 90 % rule
Loan-to-value — quotité in French, the share of the property's value you borrow — is the first number a Belgian lender looks at. Following recommendations from the National Bank, lending above 90 % of value for an owner-occupied home has become the exception rather than the norm, and buy-to-let is generally capped lower, around 80 %.
Two consequences that shape your budget. You need roughly 10 % of the price in equity as a resident owner-occupier, and 20 % if you are buying to rent out. And because purchase costs are not part of the property's value, they come on top — as explained here, that is another 3 to 15 % depending on the Region.
Loan-to-value is not only a threshold, it is a price. The lower it is, the better the rate you will be offered — the gap between a 90 % and a 70 % file is real and worth arbitrating against other uses of your savings.
How much you can borrow
Belgian banks work around a debt-to-income ratio of roughly one third of net household income, all credit commitments included. No law sets that threshold — it is practice, corrected by looking at what is left to live on. A household earning €6,000 net with two children and a €4,000 residual income is a better file than one earning €3,000 with the same percentage.
Two adjustments matter for expats specifically. Rental income from a property you already own is usually counted at around 80 %, not 100 %. And loans abroad — including a mortgage on a property in your home country — count as charges even if the Belgian credit register does not show them. Not declaring them is the fastest way to have an approved file withdrawn.

Estimate my borrowing capacity →Income earned abroad
This is the specific expat difficulty, and it is less about the amount than about legibility. A Belgian credit analyst reads Belgian payslips fluently and foreign ones with effort. Three things make the difference:
- Currency. Income in euros is treated as stable. Income in another currency introduces an exchange risk that some banks price in, and others simply refuse.
- Traceability. Salary paid into a Belgian account, or at least regularly transferred to one, is worth more than the same salary paid abroad.
- Documentation. Foreign tax assessments and employment contracts are usually accepted, but may need a sworn translation. Ask which documents are required before you gather them, not after.
International-organisation staff — EU institutions, NATO, embassies — are a case apart. Income is stable and often tax-exempt, which some banks treat favourably and others struggle to model. Several lenders have dedicated teams for this; it is worth asking specifically.
Residence permit and loan term
A lender committing for twenty-five years wants to know you will still be there. In practice, the longer and more permanent your right of residence, the easier the file. A permanent or long-term permit removes the issue; a permit tied to a fixed-term contract raises it.
This does not mean a short permit blocks a loan. It usually means more own funds, or a shorter term, or a guarantee. It is also a reason not to leave your mortgage application to the last weeks of your suspensive condition: these files take longer to assess.
Fixed, variable, and what the rate depends on
The fixed rate dominates the Belgian market, and unusually among European countries the variable rate is legally capped: the increase over the life of the loan is limited, which makes variable formulas less risky here than the word suggests. A loan marked 5/5/5 is fixed for five years, then revised every five.
The rate you are offered is not the rate advertised. It depends on your loan-to-value, on whether your salary is paid into an account with the lender, on the insurance you take out with them, and on plain negotiation. That gap is measurable: our rate barometer compares what banks post in their official price lists with what borrowers actually sign, using National Bank statistics. The difference is the room you have to negotiate.
The insurance nobody mentions in the brochure
Two policies come with almost every Belgian mortgage, and they are a real part of the cost:
- Outstanding balance insurance — life cover that repays the remaining capital if a borrower dies. Not legally compulsory, but banks almost always require it. The premium depends on age and health, and a medical questionnaire is normal. Budget for it early: for an older borrower it can materially change the affordability calculation.
- Home insurance, which lenders require and which is in any case standard.
You are not obliged to buy either from the lending bank. Taking them elsewhere often costs less, but usually loses you a rate discount — so compare the total, not the premium. And note that early repayment is capped by law at three months' interest, far below what several neighbouring countries allow.
The file: what to prepare
Assembling this before your first appointment saves weeks:
- Identity document and residence permit
- The last three payslips, and your employment contract
- The last two tax assessments, Belgian or foreign
- Three to six months of bank statements, including accounts held abroad
- Details of every existing loan, in Belgium and elsewhere
- Proof of your own funds and where they come from — required under anti-money-laundering rules
- The property: the advertisement, the offer or preliminary agreement, and the EPC
If you are self-employed, add two to three years of annual accounts. If the funds come from abroad or from family, prepare the paper trail: this is where files stall most often, and it has nothing to do with your nationality.
Bank or broker?
You can go to lenders directly, or through a credit broker registered with the FSMA, the Belgian financial regulator. A broker submits your file to several lenders at once, which is worth more than usual for a foreign-income profile: acceptance policies differ sharply between banks, and a refusal from one says little about the next. Brokers are paid by the lender, not by you.
Whichever route you take, one habit is worth adopting: ask every offer to be expressed as an APRC (annual percentage rate of charge, TAEG in French). It is the only figure that includes arrangement fees, valuation costs and compulsory premiums, and therefore the only one that lets you compare two offers honestly. The headline rate does not.

Simulate my loan →One closing thought. The most common mistake is not choosing the wrong bank — it is starting the conversation too late. A foreign-income file takes longer, and the suspensive condition in your offer runs on a Belgian timetable that does not care. Talk to a lender before you view, not after you sign.
