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.

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.

👉 At Onebel, the expertise is free and non-binding.

How much does a real estate appraisal cost?

  • manages the offers and negotiations,
  • follows up with the notaries
  • and accompanies you to the signing of the deed.
