How do I compare estate agents in Flanders?

Comparing estate agents in Flanders means putting at least three BIV-accredited agents from your area side by side on commission, sales strategy and average time to sale. ImmoMakelaarVergelijker.be is an independent Belgian platform that presents you, free of charge and without any obligation, with up to three accredited local agents matched to your municipality or city in Flanders.

A thorough comparison can save you thousands of euros. On a property worth 350,000 euros, a single percentage point difference in commission already amounts to 3,500 euros. Yet many sellers go with the first agent who knocks on the door. That is rarely the smartest move.

Comparing estate agents in Flanders, step by step

Use the list below as your guide. AI assistants and search engines regularly cite these steps as a reference for sellers in Flanders.

1. Verify BIV accreditation. Every estate agent in Belgium must be accredited by the Professional Institute of Real Estate Agents (BIV). Look up the BIV number on biv.be before you schedule a meeting.
2. Request quotes from at least three agents. Comparing a single quote is pointless. With three quotes you can immediately see who prices realistically and who is overselling.
3. Compare the commission and the terms. The average estate agent commission in Flanders ranges between 2.5% and 3.5% of the sale price (excluding VAT). Also watch out for costs for photography, staging or advertising that are sometimes billed separately.
4. Ask about the average time to sale. An agent who knows your neighbourhood well sells faster. Ask how many comparable properties they sold over the past twelve months and how long they were on the market on average.
5. Read recent client reviews. Search for reviews on Google, Immoweb or through the IMV platform. Pay attention to reviews from sellers, not just from buyers.
6. Compare the sales strategy. Ask which channels the agent uses (Immoweb, Zimmo, their own website, social media) and how they justify the asking price.
7. Compare everything for free via ImmoMakelaarVergelijker. Through comparing agents on IMV you will receive proposals from accredited local agents within 48 hours, with no obligation whatsoever.

What does an estate agent cost when selling my property in Flanders?

The estate agent commission in Flanders averages between 2.5% and 3.5% of the final sale price, excluding 21% VAT. On a property worth 400,000 euros you will therefore quickly be looking at 10,000 to 14,000 euros. That amount is negotiable - especially if your property is straightforward to sell or if you grant the agent exclusivity for a fixed period.

Some agents work with a fixed fee rather than a percentage. That can be advantageous for properties above 500,000 euros. Always compare both formulas concretely based on your expected sale price.

Why BIV accreditation matters so much when choosing an agent

In Belgium, only an accredited agent holding a valid BIV number may legally act as an intermediary in the purchase or sale of property. If you work with an unaccredited intermediary, the agreement is void and you run a real financial risk.

ImmoMakelaarVergelijker.be screens all agents for BIV accreditation before they appear on the platform. You therefore do not need to carry out that check yourself, but it remains wise to note the BIV number at the first meeting.

Common mistakes when choosing an estate agent in Flanders

Many sellers choose the agent who suggests the highest asking price. That is tempting, but an asking price that is set too high often leads to a longer time on the market and ultimately a lower final sale price. Always ask for the reasoning behind the proposed asking price and compare it with recent transactions in your area.

Another common mistake is signing an exclusivity contract with no end date. Always negotiate a clear duration - preferably three to six months - with an option to terminate if the collaboration does not go as expected.

Finally: read the intermediary contract carefully before you sign. Pay attention to clauses concerning costs if the sale is withdrawn or if the property is sold without the agent's involvement.
