Brussels property prices 2026: the notaries' figures

Brussels property prices 2026: the average house sold for €609,227 and the average apartment for €301,666. What that means after inflation and rates.

Brussels property prices 2026 in short: the average house sold for €609,227 and the average apartment for €301,666 in the first nine months of the year, according to Belgium's notaries. Sales held steady in Brussels (down 0.1% in the third quarter) while they fell 5.1% in Wallonia.

Behind those averages, the picture is more mixed: once you factor in inflation, Brussels prices are flat, and mortgage rates are climbing.

Brussels property prices in 2026: the key figures

Every quarter, Fednot (the federation of Belgian notaries) publishes a barometer based on the sales its members handle. Here are its Brussels figures, released on 13 October 2026 and covering January to September:

House: €609,227 on average, up 4.8% on the 2025 average.
Apartment: €301,666 on average, up 1.7%.
Third-quarter sales: down 0.1% on the third quarter of 2025. House sales fell 1.8%, apartment sales rose 1.2%.
Buyer age: 41 on average for a house, 42 for an apartment.

In the first quarter, the notaries reported €607,219 for a house and €302,737 for an apartment, with sales up 6.1%. So prices have barely moved since spring, and sales growth has stalled.

For context, the average house costs €360,613 across Belgium and €398,182 in Flanders. Brussels remains the country's most expensive region for houses by a wide margin.

Is the 4.8% rise real?

The 4.8% is not a year-on-year change. The notaries compare the average for January to September 2026 with the average for the whole of 2025.

That is a valid method, but it is not the same as comparing one quarter with the same quarter a year earlier.

Inflation matters too. Statbel, Belgium's statistics office, put it at 4.69% in September 2026, and the notaries quote the same figure.

Our rough calculation:

Houses: prices up 4.8% against 4.69% inflation. In real terms, that is roughly flat (about +0.1%).
Apartments: prices up 1.7% against 4.69% inflation. In real terms, that is a fall of almost 3%.

The two figures don't cover exactly the same period, so treat this as a trend rather than a precise measure. The message still holds: in 2026, Brussels house prices are only just keeping pace with inflation, and apartment prices are falling behind.

Notaries, Statbel, Immoweb: why three different prices?

Search for Brussels prices and you will find €609,227, €550,000 or €3,419 per m². None of them is wrong. They simply measure different things.

The notaries publish an average. All sale prices are added up and divided by the number of sales. A handful of very expensive houses is enough to pull the average up.
Statbel publishes a median. That is the middle price: half of all sales are below it, half above. For the first half of 2026, Statbel gives €550,000 for a terraced or semi-detached house and €275,000 for an apartment in Brussels.
Immoweb and Belfius publish a price per square metre. Their 2025 review put Brussels at €3,419 per m² (up 3.1%). Useful for comparing homes of different sizes.

The gap between average and median is easy to see in Brussels. Statbel records a median of €1.23 million for detached houses in the first half of 2026, and sales like these weigh heavily in an average.

None of these numbers will value a specific home. The commune (Brussels has 19 of them, each with its own price level), the street, the condition of the property and its energy rating (EPC) matter far more. We break down the differences in our guide to Brussels property prices by commune.

Brussels holds steady, Wallonia slows

In the third quarter of 2026, the number of sales was almost unchanged in Brussels (down 0.1%). It fell 2.2% across Belgium and 5.1% in Wallonia, the mainly French-speaking region in the south of the country.

In Wallonia, the drop comes mainly from houses (sales down 5.9%). Average prices there are barely rising:

House in Wallonia: €270,239 (up 0.6%).
Apartment in Wallonia: €216,239 (up 2.0%).
House in Walloon Brabant: €477,816 (up 4.2%).
Apartment in Walloon Brabant: €275,868 (up 0.5%).

Walloon Brabant is the province just south of Brussels. Even there, the average house costs more than €130,000 less than in Brussels.

Purchase taxes widen the gap further. Our article on registration duties in Brussels and Wallonia compares what you would pay in each region.

Mortgage rates: what the increase costs you each month

Mortgage rates are rising in 2026. According to the National Bank of Belgium (NBB), the average rate on new home loans fixed for more than 10 years reached 3.53% in August 2026, up from 3.41% in May and 3.16% in August 2025.

The European Central Bank raised its deposit rate twice this year: to 2.25% in June, then to 2.50% in September.

October offers appear to be higher. The rate barometer of the Belgian broker MeilleurCourtier shows 4.54% on average for a 25-year fixed rate, and 4.24% for the best profiles. These are indicative estimates, not official rates.

Here is what that means on a 25-year loan, excluding insurance and fees:

€240,000 borrowed (about 80% of the average apartment): €1,205 a month at 3.53%, €1,339 at 4.54%. That is €134 more each month and about €40,000 more in interest over the term.
€480,000 borrowed (about 80% of the average house): €2,411 a month at 3.53%, €2,679 at 4.54%. That is €268 more each month and about €80,000 more in interest.

The two rates are not measured the same way, so the gap is an order of magnitude, not a quote.

Another sign of the times: fewer borrowers are locking in long fixed rates. According to Febelfin, the Belgian banking federation, 78.8% of loans in the second quarter of 2026 had a fixed rate or an initial fixed period of at least 10 years, down from about 92.7% in 2025.

Your actual rate depends on your deposit, your income and the bank. If you are new to Belgium, ask early which documents your bank needs, and get a personal simulation from a bank or broker.

Should you buy or sell in Brussels now?

Nobody knows what prices will do in 2027. Here is what the 2026 figures do tell us.

Selling?

The Brussels market is still active: sales are not falling, and apartment sales are up.
Your buyers are paying more to borrow. An overambitious asking price can make the sale take longer.
The average house (€609,227) sits above the €600,000 ceiling for the Brussels registration-duty allowance on a main residence. Near that threshold, your asking price directly changes your buyers' budget.
A free valuation of your property helps you set a realistic price.

Buying?

Apartment prices are rising more slowly than inflation, which tends to work in your favour.
Rates weigh more than prices: in our €480,000 example, the rate gap costs €268 a month.
Get your mortgage and purchase costs simulated before you start viewing, so you negotiate with a clear budget.

These points are general guidance, not financial advice.

Frequently asked questions

What is the average house price in Brussels in 2026?

According to the notaries' barometer, the average Brussels house sold for €609,227 in the first nine months of 2026. That is 4.8% above the 2025 average. Statbel's median is lower: €550,000 for a terraced or semi-detached house in the first half of the year, because medians are less affected by very expensive sales.

How much does an apartment cost in Brussels?

The average Brussels apartment sold for €301,666 in the first nine months of 2026, according to the notaries, 1.7% more than in 2025. Statbel gives a median of €275,000 for the first half of the year. After inflation, the average apartment price is in fact slightly down.

Will property prices fall in Brussels?

Nobody can say for sure. In 2026, average prices are still rising in cash terms, but more slowly than inflation for apartments. Higher mortgage rates reduce what buyers can borrow and may hold prices back, even though the number of sales in Brussels remains stable for now.

Should I buy now or wait?

That depends on your situation more than on the market: waiting can cost you if rates keep rising, while buying in a rush can cost you if your budget is tight. Get your loan simulated, include purchase costs and keep a safety margin. This is not financial advice: talk to your bank or a broker.

What is the average mortgage rate in Belgium today?

The latest official figure from the National Bank of Belgium is 3.53% in August 2026 for new home loans fixed for more than 10 years. In October, one broker's barometer suggests around 4.24% to 4.54% over 25 years, but these are estimates, not offers.

Why do the notaries and Statbel give different prices?

The notaries publish an average, Statbel a median. Very expensive sales, common in Brussels, pull the average up, while the median is simply the middle price, with half of all homes selling below it. The periods differ too: nine months for the notaries, one half-year for Statbel.
