The rental market in Forest in 2026
Forest occupies a pivotal position in the Brussels rental landscape, at the crossroads between premium southern municipalities (Uccle, upper Saint-Gilles) and more affordable western ones (Anderlecht). With an average rent of 920 EUR/month for a 2-bedroom apartment and a +5.4% evolution over one year, Forest is among the municipalities where price dynamics are strongest in 2026.
The rental rate of 50% — below the regional average of 56% — reveals a mixed profile between owner-occupiers and rental investors. This configuration limits competitive pressure for landlords and maintains a controlled vacancy level. The Forest market attracts varied profiles: young first-time renters in the lower part, settled families in the Saint-Denis quarter, and executives seeking the residential calm of Altitude.
Local specifics to know
- 30% upper/lower gap: the Altitude quarter (bordering Uccle) shows average rents of 1,050 EUR/month versus 750 EUR in Bas Forest — a gap that structures the entire rental strategy across the municipality
- Forest National dynamic: redevelopment around the concert hall has driven a +8% rent increase within 500 m, with the arrival of new shops and a young professional population
- Median EPC D: score in the Brussels average, but Bas Forest properties often have an EPC E or F due to the age of the buildings — energy renovation is a significant value lever there
- Sustainable neighbourhood contract: the municipality launched an urban renewal programme in Bas Forest (2024-2030) with supplementary subsidies for landlords who renovate properties intended for rental
Tips for renting in Forest
The optimal strategy in Forest depends directly on the geographic segment targeted. In Altitude, the standard 3-6-9 lease is ideal for stable families with a moderate gross yield (3.5%) but solid patrimonial capital gains. In Bas Forest, yield potential is significantly higher (5.2% gross) thanks to still-affordable purchase prices, but tenant turnover is higher and the guarantee profile requires particular attention.
For both segments, EPC compliance remains the priority lever: properties rated E or worse no longer benefit from indexation since the Brussels reform, and Forest has one of the highest non-compliance rates in the Region. Upgrading from F to D restores indexation while capturing regional RenoLution subsidies and the supplementary neighbourhood contract premiums.
