Property valuation in Belgium: how it works and what it costs

Property valuation in Belgium: how it works and what it costs

A property valuation is the first step every seller should take before putting their home on the market. An asking price that is too high drives buyers away. A price that is too low costs you money you will never recover. Both situations are avoidable if you start from a correct, well-founded valuation.

What is an official property valuation?

A valuation - also referred to as a property appraisal or expert report - is a professional assessment of the market value of your property at a given point in time. That market value reflects what an average, informed buyer is willing to pay under normal market conditions.

In Belgium, this type of assessment is carried out by three categories of professionals: a CIB-recognised estate agent, a sworn valuer, or a mortgage expert appointed by a bank. Each category has a different approach and a different purpose. An estate agent values with a view to selling, a sworn valuer produces a legally usable document, and a bank expert works on behalf of the lending institution.

For sellers, a valuation by a recognised estate agent is generally the most practical choice. It is free, non-binding, and directly linked to the sales strategy. Through ImmoMakelaarVergelijker you can request up to three CIB-recognised agents from your area, each of whom will carry out a free valuation.

What about online property valuations?

Requesting an online valuation is today the most accessible way to get a first idea of what your home is worth. Algorithms compare your property with recently sold homes in the same neighbourhood, taking into account factors such as living area, year of construction, plot size and property type. Most tools draw on public sales data from the General Administration of Patrimonial Documentation (AAPD) and supplementary sources such as listings on property platforms. The result is an estimate delivered within seconds, without anyone having visited your home.

That has its advantages: it is fast, free and anonymous. At the same time, it comes with real limitations. An algorithm cannot see that your kitchen was recently renovated, that a garage was added, or that your garden backs onto a railway line. That kind of context is missing entirely.

Accuracy depends heavily on the region and the available sales data. In a densely populated city such as Ghent or Antwerp, where many comparable transactions take place, an automated valuation can be fairly reliable. In rural municipalities, or for atypical properties such as a farmhouse, a loft or a home with significant defects, the margin of error is often considerably larger. According to property analysts, automated valuations typically deviate by between 8 and 15 per cent from the final sale price. On a property worth 350,000 euros, a 10 per cent deviation already means a difference of 35,000 euros. That is not a small margin when you are looking to sell.

An online valuation fits well in a number of concrete situations:

• You are considering selling at some point and want to know what price range you are in.
• You want to benchmark your property against the market without contacting agents straight away.
• You are thinking about a gift or inheritance and want a first idea of the value.
• You are negotiating a mortgage and want to get your own sense of what your property is worth as collateral.

For a final asking price, an online estimate is not sufficient on its own. A valuation by a recognised estate agent, a sworn valuer, or a bank-appointed expert will always be the more reliable foundation for a well-informed decision.

What methods do valuers and agents use?

Several methods exist for determining the value of a property. The choice depends on the type of property and the purpose of the valuation.

Comparative method: This is the most widely used approach for residential property. The valuer compares your home with similar properties that have recently sold in the same neighbourhood. Price per square metre, year of construction, condition, and location all play a role. In 2025 and 2026, transaction databases such as those of Statbel and the Federation of Notaries have become the standard reference for this type of analysis.

Cost method: This involves calculating the theoretical replacement value, reduced by depreciation for age and wear. Useful for new-build properties or unusual homes for which little comparable data exists.

Income method: For investment properties or commercial premises, the valuer bases the calculation on rental income and yield to arrive at a capital value. Less relevant for the average owner-occupier.

An experienced estate agent typically combines the comparative method with their knowledge of local market dynamics. This often makes their valuation more accurate than what an online tool or algorithm can provide.

What determines the value of your property in 2026?

The Belgian property market remained relatively stable in 2025 and early 2026, but with clear regional differences. In Antwerp and Ghent, the average price of a family home is above 350,000 euros. In rural parts of Wallonia, properties are sometimes available for under 180,000 euros. That gap is exactly why local expertise matters.

These factors carry the most weight in a valuation:

• Location: proximity to schools, public transport, shops and green space
• EPC score: energy performance weighs more and more, not least because of the renovation obligations that apply or are being phased in across the Belgian regions
• Living area: for urban properties, the net habitable floor area counts for more than the total plot size
• State of maintenance: a recently renovated kitchen, bathroom or roof adds noticeably to the value
• Planning status: permitted extensions, alignment plans and any easements

A poor EPC score can already lower the sale price by several thousand euros today, because buyers factor in the renovation work that awaits them.

Do you pay for a valuation by a recognised agent?

No. In Belgium, a CIB-recognised estate agent values your home free of charge, without obligation and without a later invoice if you end up not selling through them. The agent is paid only through the commission on an actual sale, never for the valuation visit itself.

That free valuation is not a one-off gesture. It is the standard business model in the sector. The agent invests an hour or two in your property because they hope to win the sales mandate. You remain free to decline, to invite several agencies and to sign nothing. No recognised agent can charge you for a valuation visit you did not order in writing beforehand.

When does a valuation cost money? In three specific cases:

• A sworn expert report: for an inheritance, a divorce, a gift, an expropriation or a tax dispute. You then need a document that holds up against third parties, which a commercial valuation is not. Expect roughly 300 to 800 euros, depending on the complexity and the type of property.
• A mortgage valuation: requested by your bank as part of a loan. These costs, usually 150 to 400 euros, appear in your loan statement and are charged by the lender, not by the estate agency.
• A contracted valuation assignment: you explicitly order a detailed written report, separate from any plan to sell. The price and the scope of the assignment must be agreed in writing before the visit.

Outside those three situations, an ordinary seller pays nothing. If an agent announces fees for a simple valuation visit ahead of a sale, ask on what contractual basis they charge them and get a second opinion.

The real cost of a free valuation lies elsewhere. Some agents deliberately overvalue a property to win the mandate. The home then sits online for months, loses visibility with buyers and ends up with a price cut that often lands below its original market value. That overvaluation costs you far more than any paid expert report. The remedy is simple: have your property valued by several agents and treat the highest figure with caution rather than enthusiasm.

Want to know what your property is worth without committing to an agency straight away? Our free valuation page gives you a first indication, after which recognised local agents contact you for a visit. You can also compare up to 3 recognised agents in your municipality and weigh their valuations before you decide.

How to prepare for a valuation

Good preparation helps you get the most out of the visits and stops the valuer or agent from noting negatives you could have fixed yourself.

Have all documents to hand: the EPC certificate, the electrical inspection report, the soil certificate, the planning information and, where relevant, plans or permit applications. Agents and valuers appreciate transparency and take it into account positively in their report.

Make the property presentable for the visit as well. A tidy, bright space looks larger and better kept. That shapes perception, even for professional visitors.

Finally, always ask for several valuations. Price differences between agents are normal and informative. They give you a range within which you can set your asking price, together with the agent you eventually choose.
