Do I have to pay tax on the capital gain from the sale?


Yes, in certain cases.

If you sell a non-occupied property that has not been used as the main residence within 5 years of purchase, a tax of 16.5% on the net capital gain may apply.

However, there is no tax due if you sell your main residence.

Which documents do I need to provide to sell my property in Wallonia?


In a real estate sale in Wallonia, the seller must hand over a number of mandatory legal documents to the buyer:

  • Ownership title (proof that you are the lawful owner).
  • EPC certificate (Energy Performance Certificate), valid for 10 years.
  • Electrical inspection certificate (mandatory for all installations), valid for 25 years.
  • Town planning information provided by the municipality.
  • File of subsequent intervention (DLU): includes work carried out since 2001.

  • Rental agreement (if the property is rented) with inventory of fixtures.

How can I correctly estimate the value of my property?


The value depends on various factors:

  • the location,
  • the surface area and the terrain,
  • the general condition and amenities,
  • the demand in the local market.

An accurate estimate guarantees a quick sale at the best price.
An overvalued property remains on the market, loses appeal, and is often sold for less.

How much does a real estate appraisal cost?

What is the role of the real estate agent?


The real estate agent is your intermediary and advisor.
He:

  • objectively evaluates your property,
  • prepares the administrative file,
  • organizes the photos and visits,
  • manages the offers and negotiations,
  • follows up with the notaries
  • and accompanies you to the signing of the deed.

At Onebel, we take care of everything: you remain the decision-maker, we handle the rest.

What are the rates and contract conditions?


  • 1% commission VAT excluded on the achieved price, with a minimum of €2,750 VAT excluded for properties below €275,000
  • Only to be paid upon sale, not before. If the property is not sold, you pay nothing.
  • Contract of up to 3 months, monthly renewable with one month's notice as opposed to other agencies where this is 6 months.

Our contracts are simple, transparent, and without traps.
