How Much Was That House Sold For in Belgium - A Guide to Transaction Data

How much was that house sold for? It is a question many people in Belgium ask themselves - whether you are curious about a neighbouring property, want to estimate the value of your own home, or simply want to know what the market is doing right now. In Belgium, the answer is not always easy to find, but there are ways to track it down. In this guide, we explain how to discover sale prices and what you can do with that information.

Why do you want to know how much a house sold for?

There are many good reasons to want to know what houses in your area have sold for:

Determining the value of your own property: Thinking about moving or investing? The sale prices of similar homes in your neighbourhood give you a realistic idea of what your own property is worth.

Market insight: By tracking past sale prices, you can spot trends. Are prices rising or falling in your area? This helps you make better-informed decisions.

Mortgage negotiation: Banks use comparable recently sold properties to assess your mortgage application. Knowing these prices helps you negotiate from a stronger position.

Investment: For property investors, tracking transaction prices is essential for calculating returns and analysing the market.

Curiosity: Sometimes you simply want to know what your neighbours paid or how much the house further down the street sold for!

The complicated reality in Belgium

In many countries (the US, the UK), house sale prices are publicly available. In Belgium, it is a little more complicated. Sale prices are not automatically public, but there are ways to find this information.

Why not automatically public? It is largely a historical matter. In Belgium, property transactions are handled through notaries, and many Belgians value their privacy - they do not want everyone to know what their home cost. This sensitivity is culturally more pronounced than in other countries.

That said, the government does publish anonymised data covering all transactions, and you can use these to identify trends and price levels.

The best ways to find sale prices

1. Property portals (the fastest method)

Websites such as Immoweb, Zimmo, Vlan and Idea.be display current listings, but also historical sale data for some properties. Not everything is available - some agents enter prices, others do not - but it is a good starting point.

How it works:

• Go to Immoweb.be or a similar site
• Search for the neighbourhood or street
• Filter by “recently sold” or “sold”
• Click on individual properties to see previous sale prices (where available)

Advantages: Free, fast, often up to date.
Disadvantages: Not all transactions are included; some prices are missing.

2. Notary data and public registration (the most reliable method)

In Belgium, every property sale is registered with the notary. This data is published in anonymised form, but is not directly accessible to the general public in a straightforward way.

IN FLANDERS:
If you live in Flanders, the government provides statistics on all transactions via:

• https://crab.agiv.be (Centraal Referentieadressenbestand)
• https://www.vlaanderen.be/digitale-diensten (search for “huizenprijzen” or “transacties”)

IN WALLONIA:
Wallonia offers similar data, though it is somewhat less accessible. These figures are available through the FPS Finance and statistics published by the Walloon Region.

MONITEUR Notarial (all of Belgium):
Notaries publish all transactions anonymously via the Moniteur Notarial. This is public, but not always easy to find online. Your notary does have access to it.

Advantages: Official, reliable, covers all transactions.
Disadvantages: Less user-friendly; requires some research.

3. Consulting your own notary

Your local notary has access to all transactions in your area. This is a perfectly legitimate approach - notaries are happy to help members of the public with questions about local market prices.

How it works:

• Get in touch with a notary
• Ask what houses in your street or neighbourhood have recently sold for
• Many notaries do this free of charge, as it demonstrates their market knowledge

This can be particularly valuable because notaries know the actual sale prices, not just the asking prices.

Advantages: Personal advice, complete information, professional expertise.
Disadvantages: You need to visit or call; not all notaries are equally willing to help.

4. Information from estate agents

Estate agents also have access to recent transactions. If you contact agents in your area and express an interest, they will often provide you with free market analyses featuring comparable properties and their sale prices.

It is actually a clever tactic - agents want to win you as a client, so they are happy to share data.

How it works:

• Contact 2 or 3 local estate agents
• Say you want to understand the market value in your area
• Ask for comparable properties and their sale prices
• They will often send you a free “market report”

Advantages: Free, fast, local expertise.
Disadvantages: They may push you towards selling; information is selective.

Practical example: how to go about it

Say you live in Antwerp and you want to know how much the house two doors down sold for.

Step 1: Open Immoweb.be, search for your street, filter by “sold”.

• You see: “This house sold for €325,000 in October 2024”

Step 2: Check this with a notary.

• You call the local notary: “Can you tell me what a house in my street recently sold for?”
• The notary replies: “Yes, I can give you the general price levels in your area” (anonymously).

Step 3: Ask an estate agent.

• You contact a local agent: “I am curious about recent sales in my area.”
• The agent sends you a report featuring 5 to 10 comparable properties and their prices.

Result: You now have a clear picture of the local market.

What you can learn from sale prices

Sale prices tell you more than you might think:

Local trends

If you see that houses in the same neighbourhood sold for €250,000 last year and are now selling for €270,000, prices are rising. That is useful information for your own plans.

Price per square metre

A 150 m² house that sold for €300,000 = €2,000 per m². You can use this figure to value other houses in the same neighbourhood.

Negotiating position

If you want to buy a house and you know that similar properties have sold for less, you have grounds to negotiate.

Investment return

For property investors, sale prices help determine whether a rental yield is attractive.

Warnings: what you need to know

Asking price ≠ sale price: What an agent asks for is not always what the house ends up selling for. The actual sale price may be lower (especially after negotiation).

Circumstances vary: A house that had to be sold quickly may go for a lower price than an identical property that was carefully brought to market.

Every property is unique: Two houses on the same street can differ considerably (aspect, renovation needed, etc.). Always compare multiple transactions.

The market moves fast: Prices from 2023 are less relevant in 2025. Focus on recent transactions (the last 6 to 12 months).

Anonymised does not always mean identifiable: Sale prices are anonymised, so you will not know the exact house numbers - but a notary can sometimes help you with that.

In summary: how much was that house sold for?

The question “How much was that house sold for?” is not always straightforward to answer in Belgium, but there are routes:

1. Property portals (Immoweb, Zimmo): Fast and free, but incomplete.
2. Notary data: Official and reliable, less user-friendly.
3. Your notary: Personal advice, anonymised data.
4. Estate agents: Free market report, selective information.

Combine these sources for a complete picture of your local market.
