“In Flanders, the number of sales fell by 1.1 per cent. The figure was -1.2 per cent for houses and -0.7 per cent for apartments. In Brussels, sales remained virtually stable (-0.1 per cent). In Wallonia, it fell by 5.1 per cent,” said notary Bart van Opstal, spokesperson for Notaris.be.
Rising interest rates drove the decline in sales. “Borrowing has become more expensive in recent months, slightly cooling our property market. Interest rates will remain the decisive factor in the coming months, too. In Flanders, the announced increase in registration tax will also have some effect, but its impact is likely to be limited,” said Bart van Opstal.
