What is the average apartment price in Wallonia in 2026?

Walloon apartment prices rose 7.2% across 2025, the latest full-year data read into 2026 (source: Notaire.be, February 2026). Flats climbed more slowly than houses, whose median reached 240,000 euros, so the gap between the two narrowed less than in previous cycles.

Apartments tell a quieter version of the same story. Where Walloon houses jumped 15.4% in 2025, flats rose 7.2% over the same period, according to Notaire.be figures published in February 2026. Both went up, but the split is worth understanding: house demand was supercharged by the 3% registration-duty reform on an own and sole home, which typically favours family buyers looking for a house, while the apartment segment leans more on investors and first-time solo buyers who move on different signals.

Provincial detail sharpens the picture. Namur province recorded a median apartment of 205,000 euros, up a strong 13.9%, while Liège province sat at 183,000 euros (+6.2%). In Dinant, apartment medians reached 175,000 euros with an eye-catching 18.8% rise. The counter-intuitive takeaway is that “apartment” is not a single market: a central Namur flat and a Dinant riverside unit can move at very different speeds in the same year.

Per square metre, apartments often out-price houses in the same town because they cluster in central, well-connected streets. In Marche-en-Famenne, for instance, flats ran near 2,214 euros per square metre against houses at 1,516 (source: Immoweb, January 2025).

Because location, floor, lift and PEB rating swing an apartment’s value sharply, a comparable-sales analysis on your specific building beats any regional average.
