There are several ways to help you estimate your property. Above all, you must objectively compare your property with those on the market or already sold recently. The comparison must be made on the number of rooms, the living area or surface area of the land and the location. The DVF or Land Value Application site contains information on real estate transactions that have taken place over the past 5 years. You will therefore find in the map the details of sales such as the type of property, the area, the selling price, etc…. You can see for yourself what goods were sold in your neighbourhood and at what price. This will give you an initial idea of the value of your property.
