The National Bank of Belgium published statistics on key developments in the Belgian mortgage market in 2025, showing a sharp expansion in new lending for house purchases and a marked increase in average loan sizes. New mortgage lending volume rose to EUR 40.7bn in 2025 from EUR 31.7bn in 2024, with an annual growth rate of 3.9% compared with around 2.0% in each of the previous two years. The share of new loans for purchasing real estate, with or without renovation works, remained broadly stable at around 75.0%, while the share for new builds fell from 14.1% to 11.0% over two years. Excluding refinancings, the average new loan value increased to EUR 187,632 from EUR 168,656, mainly reflecting larger mortgage loan sizes, and long-term contracts remained the most common product type at 74.3% of average monthly volumes despite rising interest rates on new long-term contracts.
