Best mortgage for expats in Belgium (2026)

Buying a home in Belgium as an expat is very possible, but the order of events matters more than in many countries. Banks lend to people who already live here, several want your main income paid in euros, and the purchase triggers a regional registration duty that you pay largely from your own savings. The mortgage rate is only one part of the decision.

This guide is for people who have moved to Belgium, are registered at their commune and are thinking of buying their own home. We compared eight lenders on what they publish: a fixed rate for a term of about twenty years, a representative APR (annual percentage rate of charge, the all-in cost of the loan), the residence and income conditions in their prospectus, whether the information exists in English, and the maximum term.

Three questions decide your shortlist. Do you meet the bank’s residence and euro income conditions? Can you follow the process in the bank’s language? And which discounts can you actually use, given that most of them depend on buying the bank’s insurance or moving your salary?

How to choose a mortgage in Belgium as an expat

Residence and euro income come first

Belgian lenders write their target clients into their legal prospectus. KBC, Argenta, vdk and Beobank prospectuses limit mortgages to people living or domiciled in Belgium; KBC, Argenta, vdk and Crelan also require main income in euros. (source, checked 2 November 2026) In practice this means you apply after you have moved, registered at your commune and started being paid. Crelan goes further: its prospectus excludes consumers whose repayment income is not in euros, even when the payslip shows a converted amount, and people living in a country that does not use the euro.

If you are paid in dollars, pounds or Swiss francs by a foreign employer, ask the bank at the first contact whether your income counts. Do not spend money on a valuation or a notary before you have that answer in writing.

Published rates are a starting point

Banks publish dated rate sheets, but the rate you are offered can differ. vdk states that the final rate depends on the project, the term, the loan-to-value, your repayment capacity and your risk profile. The sheets are also not comparable line by line: term buckets differ, some sheets already include conditional discounts, and others show both a base rate and a discounted rate. Use the published figures to choose which two or three banks to talk to, then compare written offers.

Discounts tied to insurance and your salary

Most of the gap between a base rate and an attractive headline rate comes from conditions. KBC, Argenta and Crelan cut the rate if you take their credit life insurance (a policy that repays the loan if a borrower dies) and their home or fire insurance, and some banks also want your salary paid into an account with them. vdk publishes the opposite: surcharges if you do not move your salary or take its life cover. You can choose another insurer, but you then lose the discount. Compare the full monthly cost, loan plus insurance premiums, not the rate alone.

Energy efficiency also counts. Argenta, vdk, Crelan, Beobank and Belfius all publish a discount or a longer term for energy-efficient homes or renovations that improve the EPC (energy performance certificate).

The registration duty depends on the region

When you buy an existing home you pay a registration duty to the region where the property is, on top of the price. The rules differ a lot, and they changed recently.

In Flanders: Flanders: sales duty is 2% on the purchase of your sole own home (natural persons; register at the address within three years); the basic rate is 12%. (source, checked 2 November 2026) The mortgage itself also carries a duty in Flanders: Flanders: mortgage establishment duty is 1% of the loan amount secured by a mortgage. (source, checked 2 November 2026) Some non-official sources report that the Flemish conditions are changing from 2026; we could not confirm this on vlaanderen.be, so check the official page before you sign.

In Brussels: Brussels: registration duty is 12.5%; no duty on the first EUR 200,000 for a buyer's only home, if the price does not exceed EUR 600,000. (source, checked 2 November 2026) The conditions are strict: Brussels abatement: main residence within 3 years of registering the deed, kept for an uninterrupted 5 years; extra EUR 25,000 abatement per energy class improved, from a minimum of two classes. (source, checked 2 November 2026) Changes to the Brussels conditions from 2026 were mentioned by non-official sources; confirm the current rules on the Brussels Fiscality page.

In Wallonia: Wallonia: since 1 January 2025 the rate for a sole own home is 3% instead of 12.5%. (source, checked 2 November 2026) The conditions: Wallonia 3% rate: move in within 3 years (5 for building land), stay 3 full years; an existing fully owned home (Belgium or abroad) must be sold within 3 years. (source, checked 2 November 2026) And one older advantage has ended: Wallonia: the chèque-habitat no longer applies to homes acquired or built from 2025. (source, checked 2 November 2026) The mortgage registration duty for Brussels and Wallonia was not collected for this guide; your notary will calculate it.

Check that the lender is authorised

Every lender in this guide is a Belgian credit institution. You can check any lender or credit broker in the FSMA search for lenders and intermediaries. The National Bank list was unreachable on the day we checked, so we used the FSMA records.

The providers compared

Lenders appear in score order, as in the table. The scores weight English access and service heavily, so a bank with an accessible English process can come out ahead of banks that publish lower rates. A point we could not verify is left out of the score, and a lender with too few verified points is shown as not rated.

BNP Paribas Fortis is not rated: its website returned a maintenance error throughout our check, so nothing about its mortgages could be verified. If you hold your current account there or at its app brand Hello bank!, ask for a written mortgage offer and compare it with the published rate sheets in this guide.

If you are paid in a currency other than the euro

This is the most common blocker for expats. KBC, Argenta, vdk and Crelan all require your main income in euros, and Crelan excludes even a foreign salary converted to euros on the payslip. If your employer pays you in another currency, raise it before anything else. Options worth discussing with a bank are having the contract changed to pay in euros, or a co-borrower whose income is in euros; whether a bank accepts either is its decision.

If you have only just arrived

Banks lend to people who live here. Beobank requires domicile in Belgium at signing, KBC lends only to residents with euro income, and vdk wants habitual residence. Register at your commune, get your residence card and collect a few months of Belgian pay slips before you start. In the meantime, open a current account and build savings: you will need your own money for the registration duty, the notary and the bank’s fees, because KBC, for example, never lends more than the total cost of the home.

If you are buying your first home

First-time buyers have advantages. KBC offers first-time buyers an extra rate discount and lends up to the full value of the property. The regional duty reductions for a sole own home in Flanders, Brussels and Wallonia described above are designed for you, but each comes with conditions on moving in and staying. Read them on the official pages before you sign the purchase agreement, because signing it commits you to the purchase.

If you plan to leave Belgium within a few years

The Brussels abatement requires you to keep the home as your main residence for five uninterrupted years, and Wallonia’s reduced rate requires three full years. If your contract in Belgium is temporary, check on the official regional pages what happens to the reduction if you move out early.

Step by step: getting a mortgage in Belgium

1. Register at your commune and get your residence card.
2. Collect recent pay slips, your employment contract and an overview of your savings.
3. Run simulations at two or three banks; at least one should be KBC Brussels if you need English.
4. Ask each bank whether your income meets its euro income condition and how much it will lend.
5. Find the property and sign the purchase agreement, ideally with a clause that makes it conditional on obtaining the loan.
6. Send each bank the signed agreement and the EPC certificate; ask for written offers with the APR and the cost of the required insurance.
7. Compare the full monthly cost, choose, and sign the loan and the deed at the notary.

Our verdict

KBC Brussels comes out ahead in the table. KBC Brussels is the pick for most expats who want to follow the process in English: English product information, an English prospectus and a dedicated expat team, at a higher published base rate. Argenta and Beobank published the lowest fixed rates and suit buyers who can deal with a branch in Dutch or French. vdk fits Dutch speakers in Flanders happy with a long initial fixed period, and Crelan fits euro earners buying an energy-efficient home who want a longer term. Belfius, ING and BNP Paribas Fortis could not be fully compared because they did not publish rates we could read; ask them for written offers and compare them with the sheets above.
