The rental offer in Brussels

🤔 We regularly read that the volume of rental listings in Brussels is collapsing.

Is that really the case?

At SmartBlock, we track changes in supply in real time to give experts and investors an objective view of what’s happening on the ground.
Here’s what our data tells us about Brussels:

1️⃣ Structural growth: contrary to popular belief, the underlying trend has been a slight, steady increase for three years.

2️⃣ Strong seasonality: we observe a gap of up to 60% between the low point and the high point within the same year. There is always a dip in December and a peak in listings in June.

The takeaway is simple:
Comparing December inventory to June inventory is like confusing a seasonal decline with a real market trend.

Our conviction:

To assess the true health of supply, avoid quarter-to-quarter comparisons. Always favor year-over-year (Year-on-Year) analysis to smooth out these seasonal variations and identify the real underlying trend. It’s the best way to ensure your investment decisions and valuations are based on reliable data, not temporary fluctuations.
