Average rents in Brussels rose by 1.5% in the first half of this year compared with autumn 2025, pushing the average monthly rent above €1,400 for the first time.
The average rent across all housing types reached €1,401 a month, according to the Confederation of Real Estate Professions and Korfine, based on an analysis of tenancy agreements signed through estate agencies. The median rent, which means half of homes cost less and half cost more, remained unchanged at €1,250 a month.
Although rents increased more slowly than inflation, CIB said the spring figures should be treated with caution.
