Why Houses Are Expensive in Belgium: 8 Economic Reasons

Why houses are expensive in Belgium A question on everyone's lips: why have homes in Belgium become so unaffordable? Ten years ago you could buy a reasonably decent house for €200,000. Today you easily pay €350,000 for the same property. This is no coincidence - there are concrete economic reasons behind this explosion in house prices. In this analysis we explain why houses are so expensive.

1. Housing scarcity (supply < demand)

The biggest reason: there are simply too few homes for too many buyers.

The causes:

• Belgian municipalities are not building enough new housing
• Much land is reserved for other purposes (industry, agriculture, public land)
• Spatial planning rules are strict - you cannot build just anywhere
• Construction procedures take a long time (permits, bureaucracy)

The consequence:
More buyers than available homes = prices go up. This is basic economics: demand higher than supply = price rises.

The numbers:
In Brussels and across Belgium, the housing shortage is chronic. For every property sold, there are at least 2 to 3 potential buyers interested. This pushes prices up sharply.

2. Low interest rates (until 2022)

For the past 15 years, interest rates were historically low. This was a golden era for buying - but it drove prices up considerably.

How it worked:

• Low rates (0.5% to 1.5%) meant low monthly repayments
• If you borrow €300,000 at 3% interest: you pay roughly €1,300/month
• The same loan at 5% interest: you pay roughly €1,600/month

The consequence:
With low rates, more people could get a mortgage, so demand for homes increased. And more demand = higher prices.

Recent shift:
In 2022-2023, rates rose sharply (3% → 5%). This should have pushed prices down. But the opposite happened - many properties were sold quickly before rates climbed even higher. This triggered a last-minute rush, which actually drove prices up further.

3. Inflation and rising costs

Everything has become more expensive - including homes.

What is rising:

• Building materials: timber, steel, cement, insulation - all at least 20-30% more expensive since 2020
• Labour: construction workers demand higher wages (understandably, given inflation)
• Energy: this affects renovation work and the transport of materials
• Land prices: because land is scarce, its price is rising too

Example:
A house that cost €300,000 to build in 2019 now costs €380,000+ for the same quality.

Consequence:
Sellers ask for more because their costs were higher. This puts upward pressure on the entire market.

4. Investors and speculators

Many wealthy foreigners, companies and private investors buy properties not to live in - but to make money.

What happens:

• Investors buy properties speculatively
• They renovate them cheaply and sell them at a high price
• Or they rent them out at high rents
• This draws large amounts of capital into property

The problem:
This capital squeezes ordinary buyers out of the market. Investors can bid more because they do not need to live in the property - they see it as an investment. This drives up prices for everyone.

The numbers:
In Brussels, approximately 30-40% of all housing is owned by investors or companies - not by families who actually live there.

5. Registration duties and transaction costs (passed on by sellers)

Sellers face significant costs when selling. They pass these on in the asking price.

Costs involved:

• Registration duties (paid by the buyer - 12.5% in Wallonia and Brussels, with possible reductions under certain conditions): roughly €30,000-€50,000 on a €400,000 home
• Estate agent commission (3-4%): roughly €12,000-€16,000
• Notary fees: roughly €3,000-€5,000

Total: roughly €45,000-€70,000 on the sale of a €400,000 home!

Consequence:
Sellers increase their asking price to recoup these costs. This weighs on the entire market. A house that is
