How Mortgages Work in Belgium

The ECB’s key refinancing rate directly influences Belgian mortgage pricing. Belgian banks add their margin on top of the swap rate for fixed-rate products and the Euribor rate for variable-rate products

Types of Mortgages Available

Belgian buyers can choose between fixed-rate mortgages (taux fixe/vaste rentevoet), variable-rate products that adjust annually or every 3-5 years, and semi-fixed products with an initial fixed period. The most popular product is the fixed-rate mortgage, providing payment certainty. Belgian law caps how much a variable rate can increase — typically it cannot more than double from its initial level, providing built-in protection for borrowers

How Much Can You Borrow?

Belgian lenders assess affordability based on the debt-to-income ratio, typically ensuring total debt repayments do not exceed one-third of net household income. Both borrower and co-borrower incomes are considered

The maximum loan-to-value in Belgium is The National Bank of Belgium recommends maximum 90% LTV for owner-occupied properties and 80% for investment properties. First-time buyers may access up to 90% from some lenders. At least 10% deposit plus funds for registration duties and fees is expected. Loan terms extend up to Standard terms range from 15 to 25 years, with 20-year terms being the most common. Maximum term is generally 30 years, but terms beyond 25 years are rare.

The Application Process

The process begins with a credit simulation at the bank. You will need proof of identity, income documentation (three recent payslips, tax returns), details of existing debts, and information about the property including the compromis de vente. The bank conducts a property valuation. Approval typically takes 2-4 weeks. A notary handles the mortgage deed registration

Costs and Fees

Mortgage registration tax (hypotheekinschrijving) is approximately 1% of the loan amount plus notary fees. Some banks charge a dossier fee of €250-500. Early repayment penalties are capped at 3 months’ interest on the repaid amount

What Makes Belgium’s Mortgage Market Unique

Belgian mortgages often include a mandatory fire insurance policy (brandverzekering) and outstanding balance insurance (schuldsaldoverzekering), which clears the mortgage if the borrower dies. The schuldsaldoverzekering premium is particularly important to factor in, as it can be significant for older borrowers or those with health conditions

Refinancing Your Mortgage

Refinancing is common in Belgium when rates drop significantly. The early repayment penalty (wederbeleggingsvergoeding) is capped at 3 months’ interest. However, you also need to factor in new notary fees and registration tax for the new mortgage, which can offset savings unless the rate difference is substantial — typically at least 1% lower to make refinancing worthwhile

Government Schemes and Support

Flanders offers a reduced registration duty of 3% for primary residences. Some regions provide a housing bonus or tax advantages on mortgage repayments, though the federal woonbonus has been abolished in most regions. Check current regional incentives as these change frequently

Tips for Getting the Best Deal

Always compare offers from at least 3-4 banks, as Belgian mortgage pricing varies significantly between lenders. Use a mortgage broker (hypotheekmakelaar) if you want access to multiple offers without visiting each bank. Pay attention to the AEIR (Annual Effective Interest Rate) which includes all costs, not just the headline rate
