NBB Loan-to-Value (Quotiteit) Caps

The National Bank of Belgium (NBB) imposes macroprudential lending limits on residential mortgages: a 90% LTV ceiling for first-time owner-occupiers (with banks permitted a 35% portfolio exception tolerance), 80% for buy-to-let investments, and a maximum 50% debt-service ratio (woonquote).

Legal Caps on Variable Rate Loans

Under Belgian consumer credit law, variable rate mortgages are subject to statutory safety caps (e.g. Cap 1, Cap 2, Cap 3): the interest rate can never rise above a legally specified ceiling and can never more than double the initial contractual rate.

Mandatory Insurance (SRD and Brandverzekering)

Lenders require borrowers to obtain outstanding balance life insurance (Schuldsaldoverzekering / ASRD) and comprehensive fire/building insurance. While banks offer bundled interest rate discounts for buying their policies, borrowers are legally free to shop for external insurance.

Regional Registration Duties (Registratierechten)

Property transfer taxes differ significantly across Belgium: 3% for primary residences in Flanders, 12.5% in Wallonia (with base tax abatements), and 12.5% in Brussels (with a €200,000 tax-free abatement for primary purchases).
