Property prices soar
Property prices have skyrocketed in Belgium in recent years. The price of a typical Belgian house has risen by more than 60% over the past 14 years, outpacing wages, inflation and even the expectations of many homeowners.
Figures published earlier this month by Belgian statistical agency Statbel show the median price of a terraced or semi-detached house in Belgium reached €260,000 in 2024, up from €160,000 in 2010. Detached homes, some of Belgium’s most expensive properties, now average €370,000, while even a modest apartment will cost around €243,000.
Inside the Brussels‑Capital Region, the price ladder is steep. Earlier this year, The Brussels Times reported that the average price of a detached house in Brussels had topped €1.1 million, with terraced houses reaching €485,000.
