According to figures from the latest edition of the ‘Notary Barometer’, flats in the Brussels-Capital Region cost an average of 297,411 euro. The ‘Notary Baramoter’ is a quarterly report on real estate prices that is published by Notary Federation (Fednot).
The figures for the 3rd quarter of 2025 show that the Brussels-Capital Region remains the most expensive region in Belgium for those wishing to buy a flat. In Flanders the average price of a flat is 286,152 euro, a rise of 1.3% on this time last year. Wallonia remains the cheapest region for flat buyers with flats there costing an average of 209,952 (+5.8%).
The average price of a house in Brussels is also higher than elsewhere in Belgium. Currently, houses in the Brussels-Capital Region cost an average of 577,108 euro, 1.2% more than a year ago.
In Flanders a house costs on average 376,462 (+2.4%). Although Wallonia has seen the sharpest year-on-year rise in house prices (+12.9%) it is still the cheapest of the 3 regions. The average price of a house in Wallonia is 269,551 euro.
Notary Bart van Opstal told the Brussels regional news platform Bruzz that the sharp rise in house prices in Wallonia can be explained by the reduction in property transaction tax that came into force there at the start of the year. "This has led to an increase in sales, while the number of available properties remained relatively limited”.
Property market buoyant
After several difficult years, the property market has picked up. In Brussels, the number of transactions rose by 8.6% compared with the same period in 2024. Nationwide, the increase was 15%. Fednot says that this is a sign that there is “a clear revival of the property market”.
In 2025, the average age of buyers in Brussels is 40, for both houses and flats.
