Belgian residential market in 2025: stable inflation amid rising price levels and local contrasts
Despite stability in inflation, price levels continue to rise
Belgium’s residential real estate market in 2025 is characterized by stable inflation for residential prices but persistently rising price levels. The average annual inflation rate of residential property prices remained unchanged in 2025 at 3.2%, identical to 2024, despite moderate quarterly movements. In the fourth quarter of 2025, inflation of residential real estate prices eased slightly to 3.5%, down from 3.7% in the previous quarter, signaling some short term cooling.
Nevertheless, residential real estate prices continued to increase in absolute terms: the average annual Housing Price Index (HPI) rose from 140.42 in 2024 to 144.87 in 2025, reaching 147.10 points in Q4 2025 (2015 = 100). This confirms that buying a home in Belgium became more expensive throughout the year, despite an overall stable inflation environment.
Diverging dynamics across market segments and regions
Beneath this apparent stability, however, important shifts occurred across market segments and regions. Inflation for new homes fell sharply, with the average annual rate declining from 6.0% in 2024 to 1.8% in 2025 (2.5% in Q4 2025), while inflation for existing homes accelerated from 2.6% to 3.8% (3.9% in Q4 2025). Because existing dwellings account for more than 70% of transactions, their stronger price increases largely offset the slowdown in new construction prices, resulting in stable aggregate inflation.
Regionally, the Brussels Capital Region recorded a stable and relatively low inflation for existing homes, falling to 0.9% in the last quarter of 2025 (1.7% on average in 2025), while Flanders (3.3%) and Wallonia (7.3%) recorded higher increases at the end of the year. When comparing Belgium’s inflation for residential prices with neighboring countries in Q3 2025, Belgium (3.7%) continued to sit in the middle range with Germany (3.3%), but well below the Netherlands (7.7%) and higher than France (0.7%) where price growth remained subdued.
Price increases across all housing types
Price increases throughout 2025 were visible across all major housing types. Closed and semi-detached houses recorded the strongest year-on-year growth, with median prices rising by 7.7%, from €260,000 to €280,000, reflecting sustained demand in urban and suburban locations. Prices for detached houses increased by 5.4%, reaching a median of €390,000, while apartments experienced a more moderate increase of 2.9%, up to €250,000.
During 2025, Wallonia remained the most affordable region across all housing types, with a median price of €198,000 for semi-detached or closed houses and €325,000 for detached houses. Brussels Capital Region continues to command the highest prices, particularly for detached houses, where median prices exceed €1 million and semi-detached or closed houses reach €510,000. Despite a moderation in overall inflation for residential real estate prices during 2025, these developments underline that affordability pressures persist especially in high-demand markets where price growth continues to outpace income evolution.
Most expensive municipalities for houses
At the municipal level, significant price differences remain visible, highlighting strong local concentration effects in the Belgian housing market. According to Statbel data for the full year of 2025, Sint-Martens-Latem emerges as the most expensive municipality for houses, with a median price of €792,500. Its high valuation reflects a combination of residential exclusivity, the prevalence of spacious, high-quality housing, proximity to Ghent, excellent accessibility to the coast via the E40, and a distinctly rural character. Sint-Martens-Latem is followed by Elsene (€785,000) in Brussels Capital Region, Lasne (€740,000) in Wallonia, and Knokke-Heist (€732,500) in Flanders, where for the latter, its coastal appeal and constrained supply continue to support elevated prices.
Overall, the Brussels Capital Region dominates the upper end of the market, accounting for five of the ten most expensive municipalities: Elsene, Woluwe Saint Pierre, Uccle, Woluwe Saint Lambert, and Forest. These municipalities benefit from sustained demand, international appeal, high living standards, affluent resident profiles, and limited opportunities for new residential development.
The Flemish Region follows closely with four municipalities in the top ten: Sint Martens Latem, Knokke-Heist, Kraainem, and Schilde. While Knokke Heist stands out as the only coastal municipality in the ranking, the others derive their high prices mainly from proximity to major urban centres such as Brussels, Ghent, or Antwerp, as well as their status as affluent suburban areas.
Most expensive municipalities for apartments
A similar but even more pronounced pattern emerges in the apartment segment. The Flemish coastal municipality of Knokke Heist clearly leads the ranking, with a median apartment price of €570,000, making it not only the most expensive municipality for apartments but once again the only seaside location in the top ten. It is followed at some distance by other Flemish municipalities such as Bierbeek (€405,000), Wezembeek-Oppem (€402,500), Schilde and Keerbergen, both with a median apartment price of €400,000. Only two non-Flemish municipalities appear in the top ten: Waterloo (€380,000) in Wallonia and Woluwe-Saint-Pierre (€371,250) in the Brussels Capital Region. Both benefit from a combination of residential appeal and close accessibility to the capital.
Overall, the Flemish Region clearly dominates this ranking, accounting for eight of the ten most expensive municipalities for apartments. Elevated apartment prices in these locations reflect structural supply constraints, sustained demand from higher income households, and continued interest from both domestic and international buyers. While, housing inflation at the national level has stabilised, these findings confirm that price pressures remain highly concentrated in specific high demand locations, particularly for apartments in Flanders and the Belgian coast, where local market fundamentals increasingly outweigh national pricing dynamics.
