In the second quarter of 2026 (April, May, June), 1.5% more homes were sold in Belgium compared with the second quarter of 2025. Apartment sales went up by 4.8%, while the trend for houses remained stable (+0.3%).
"This increase was almost entirely attributable to the flat market," said Notary Bart Van Opstal, spokesperson for Notaris.be.
