The facts base carries no direct inventory count, so this stays a careful read: the 2025 combination of sharply rising prices (houses +15.4%) and rising sales volumes points to demand outpacing available stock (source: Notaire.be and Fednot, 2026), the classic profile of a supply-tight, seller-favourable market.
It is more honest to infer the supply picture from price and volume behaviour than to claim a precise stock figure the data does not provide. What the verified numbers show is telling. In 2025 Walloon house prices rose 15.4% and apartments 7.2%, while transaction volumes climbed around 16% to 17% in the Liège and Namur provinces (source: Notaire.be and Fednot, February 2026).
That pairing is the signature of demand pressing against supply. When lots of buyers compete and prices jump at that pace, it usually means desirable, well-priced stock is being absorbed quickly rather than sitting unsold. The 3% own-home registration reform poured extra demand into the market from 1 January 2025 without adding a matching supply of homes, which tightens the balance further.
The counter-intuitive nuance is that “shortage” is really about the right property, not property in general. Good, well energy-rated homes at realistic prices are what move fast, so for buyers those feel scarce. Meanwhile poorly rated F and G houses can linger, so at the weaker end stock is not scarce at all. Supply pressure is uneven across the quality spectrum.
For a seller, a tight market for good homes is an opportunity: it is why pricing correctly and presenting well can produce a quick sale, the logic behind Easyhome’s promise of a sale in 15 days or the agency fees are waived.
At a glance
- No direct inventory figure in the verified data; this is an inference from price and volume.
- Prices 2025: houses +15.4%, apartments +7.2% (source: Notaire.be, Feb 2026).
- Volumes: up about 16% to 17% in Liège and Namur (source: Fednot, 2026).
- Reading: demand outpacing supply of good stock, a seller-favourable market.
- Added pressure: 3% own-home reform lifted demand without adding supply.
- Nuance: quality, well-rated homes feel scarce; poor-PEB stock lingers.
