Valuing your home: how to determine the right asking price

Valuing your home is the first and most decisive step in a successful property sale. Price too high and you scare buyers away. Price too low and you leave money on the table. An accurate valuation gives you a solid foundation from which to negotiate with confidence. In this article you will learn how a valuation works, which methods exist and when it makes sense to bring in a recognised estate agent.

Why an accurate valuation matters so much

Many sellers start with an instinctive feeling about what their property is worth. That feeling is more often wrong than right. The emotional attachment to a home clouds judgement, and comparisons with neighbouring properties or online listings are rarely reliable.

In 2026, the Belgian property market remains under pressure from a combination of higher construction costs, fluctuating interest rates and growing demand for energy-efficient homes. The average sale price of a residential property in Belgium stood at around €325,000 at the start of 2026, but the variation is enormous: a terraced house in Liège is not the same as a semi-detached property on the outskirts of Antwerp.

An asking price that is too high leads to long selling times. Properties that sit on the market develop a negative reputation. Buyers start to wonder what is wrong with them. Eventually you have to reduce the price anyway - but from a weakened position. A realistic price from the outset attracts more interested parties and leads more quickly to an offer close to the asking price.

The three most commonly used methods to value a home

There are several ways to determine the value of a property. Each has its advantages and disadvantages.

1. Comparative market analysis
Your property is compared with recently sold properties in the same area that share similar characteristics: surface area, type, year of construction, condition and EPC rating. This is the method estate agents use most often. It requires access to actual sale prices - not the asking prices you see advertised online.

2. Income approach
For investment properties, the value is calculated on the basis of rental income and expected yield. This is less relevant for owners selling their own home, but does come into play for apartments or mixed-use properties.

3. Cost approach
This method estimates the value of the land plus the reconstruction value of the building, reduced for depreciation. It is used more often by insurers than by property professionals in a standard residential sale.

For most owners looking to sell their home, the comparative market analysis is the most practical and accurate approach.

Online valuation tool or estate agent: which do you choose?

Online tools offer a quick indication based on algorithms and publicly available data. They can be useful as a first orientation, but they do not take into account the specific condition of your property, recent renovations, the plot layout, the view or any distinctive features.

A free valuation from a recognised estate agent goes much further. The agent visits the property, asks targeted questions and combines market knowledge with a physical inspection. The result is a valuation you can use at the negotiating table.

Moreover, an agent who knows the local market is aware of nuances that no algorithm will pick up: the new cycle bridge that improved the neighbourhood, the construction project around the corner putting buyers off, or the shortage of detached properties in a particular municipality.

Which factors influence the value of your property?

A professional valuation takes dozens of elements into account. The most important are:

• Location: municipality, neighbourhood, proximity to schools, public transport and amenities
• Surface area: habitable floor area, plot size, presence of a garden or terrace
• EPC rating: in 2026 energy performance carries more weight than ever; an A or B label noticeably increases the value
• Year of construction and renovations: recent work on the roof, electrical installation or heating system pushes the price up
• Property type: terraced house, semi-detached, detached, apartment or villa
• State of maintenance: a move-in-ready property achieves a higher price than one that requires work
• Legal situation: planning permits, any easements or existing tenancy agreements

All these elements together determine what a buyer is prepared to pay. No two properties are identical, which is why a tailored valuation is not a luxury - it is a necessity.

How much does a home valuation cost?

An official valuation by a sworn property valuer in Belgium typically costs between €300 and €700, depending on the complexity of the property and the region. For court proceedings or inheritance matters, such a formal valuation is sometimes required by law.

If you want to sell your property, however, you do not need to pay for this. Most recognised estate agents offer a free valuation visit as part of a potential sales mandate. Through IMV you can compare estate agents and request up to three free valuations from recognised IPI-registered agents in your area. This gives you multiple perspectives and a clear picture of the market value, with no obligation whatsoever.

When should you bring in an estate agent for a valuation?

Bringing in an estate agent for a valuation makes sense as soon as you are seriously considering selling. But a professional valuation is also useful in other situations:

• In the event of a divorce or inheritance where the value of the property needs to be established
• If you want to know whether renovations will increase the sale price enough to justify the investment
• If you want to increase or refinance a mortgage
• If you want to assess whether it is better to sell now or wait

Bear in mind: an estate agent who values your property also has an interest in getting the price right. An inflated price leads to no sale, which benefits the agent just as little as it benefits you. A good agent will give you honest advice - even if that means a lower figure than you had hoped for.
