Average prices of apartments in Belgium 2011-2021, by region

Apartment prices were very different in Flanders, Wallonia and the Brussels-Capital Region in 2021, with an apartment in Wallonia costing about 186,800 euros. Belgium has four governments, one national and three regional: Dutch-speaking Flanders, French-speaking Wallonia and the Brussels-Capital Region (the city of Brussels along with its surrounding villages). All four areas operate independently from each other.

In recent years, the housing market in Belgium remained stable. This was due to Belgium's fiscal system. When purchasing a house in Belgium, consumers pay the asking price plus ten (in Flanders) or 12 percent (in Wallonia and the Brussels capital region) in registration rights. This makes buying a house in Belgium a long-term investment. Between the third quarter of 2015 and the third quarter of 2017, the house price index of Belgium increased from 144 to 153, whilst the indices of Luxembourg and the Netherlands increased from 142 to 162 and 94 to 107 respectively in the same period.
