Comparing estate agents: how to find the best agent for your property

Anyone looking to sell their home should start by comparing estate agents in their own area. Your choice of agent has a direct impact on the sale price, the time it takes to sell, and your peace of mind throughout the entire process. Yet many sellers compare only one or two agents, or simply go with the first one who knocks on their door. That is rarely the smartest approach.

What does an estate agent actually do?

An estate agent guides you from start to finish through the sale of your property. It begins with a realistic valuation based on the local market, the condition of the property, and recent comparable sales in the area.

The agent then arranges professional photos, an attractive listing description, and publication on the relevant property platforms such as Immoweb, Immovlan and Zimmo. Interested buyers are screened, viewings are scheduled, and negotiations are handled through the agent.

Finally, a good agent coordinates with the notary and supports you right through to the signing of the deed. You do not have to manage all of this yourself - and that is precisely what you are paying the agent's commission for.

Why does your choice of agent make such a difference?

In June 2026, the average sale price for a property in Belgium hovers around 330,000 euros, but there is considerable variation from one municipality to the next. In certain districts of Antwerp or Ghent, a comparable property can fetch tens of thousands of euros more or less than in a neighbouring municipality. An agent who knows your micro-market inside out can turn that difference to your advantage.

Say two agents achieve a 3% difference in the negotiated price on a property worth 300,000 euros. That is 9,000 euros - more than enough to offset any difference in commission between agents. Local market knowledge pays off.

On top of that, not all agents work at the same pace. Some agencies regularly sell a property within 45 days; others can keep you waiting for months. Every extra month on the market has a cost: mortgage payments, property tax, insurance and maintenance all keep running.

What should you look for when choosing an estate agent?

There are a number of concrete points to check for every agent before you sign a mandate.

• BIV recognition: Every estate agent in Belgium must be accredited by the Professional Institute of Real Estate Agents (BIV). You can verify this for free using the public search tool on biv.be. Never work with an unaccredited intermediary.
• Local references: Ask for recent sales results in your municipality or district. An agent with proven experience in your neighbourhood will know the asking prices, the buyers, and the pitfalls.
• Commission and contract: Commission typically ranges between 2% and 3.5% excluding VAT. Pay attention to the duration of the exclusivity contract and the terms for cancellation. A contract of six months or more with no exit clause is a significant commitment.
• Marketing approach: Ask specifically how the agent plans to bring your property to market. Do they use professional photography, virtual tours or targeted social media advertising? Presentation plays a direct role in how many viewings you receive.
• Communication: You want to be kept informed. How often will the agent report back to you, and through which channel? An agent who is hard to reach during the sales process is a source of frustration.

How much does an estate agent cost in Belgium?

Agent fees in Belgium are freely negotiable and are generally expressed as a percentage of the sale price, excluding VAT (21%). For a standard property, you can expect 2% to 3.5%. On a sale price of 350,000 euros, that works out to a commission of between 8,470 euros and 14,823 euros including VAT.

Some agents work with a fixed fee, or a combination of a low percentage and a fixed amount. There is also a growing segment of online or hybrid agents who charge less, but in that case you take on part of the work yourself - viewings, negotiations or file management.

For a fair comparison, look not only at the percentage but also at exactly what is included. An agent who charges 2.5% and handles everything is often better value than one who charges 1.5% but bills separately for photography, listing fees and advertising.

How do you compare several estate agents efficiently?

Contacting three agents separately, scheduling appointments, comparing quotes and checking references takes a great deal of time. What's more, you often have no way of knowing whether the agents you contact are actually the ones with the best results in your municipality.

Through ImmoMakelaarVergelijker, you can compare up to three BIV-accredited local agents in a single step, completely free and with no obligation. You enter your address and a few basic details about your property, and we select the agents who score highest in your area. You receive targeted proposals and can decide for yourself who to proceed with - no strings attached.

This saves you time and lets you compare on an objective basis. No unsolicited cold calls from agents you never asked to hear from, no endless searching across comparison websites.

When should you bring in an estate agent?

The answer is: as early as possible. Many sellers wait until the property is ready for viewings, but a good agent can support you at an earlier stage - helping you decide which renovations are worth making to boost the sale price, when to time the sale, and how to prepare the file.

In practice, there are a number of documents you will need in any case: the EPC certificate, the urban planning extract, the soil certificate and, where applicable, an electrical inspection report. An experienced agent will help you request these in good time so that there are no delays when signing the sale agreement.

If you wait too long to bring in an agent, you also risk starting with the wrong asking price. Set it too low and you leave money on the table. Set it too high and your property lingers on the market, making buyers suspicious.
