Property prices in Beausoleil: where to find the real figures

DVF, impots.gouv, notaries: the official sources, their limits and how to use them

To find out the property prices actually paid in Beausoleil, you can turn to three main sources, all official and free of charge: the French State’s DVF database, the “Rechercher des transactions immobilières” service on impots.gouv and the notaries’ statistics. They are based on signed sales, but with a time lag and little information on the condition or view of the properties. To place your flat in context, they are a starting point, not a valuation.

Asking price or sale price: what are we talking about?

An advertised price is an asking price. The sources below list completed sales, signed before a notary: when it comes to property prices in Beausoleil, they are more reliable than listings.

1. The DVF database: sales published by the French State

The “Demandes de valeurs foncières” (DVF) database, produced by the French Directorate General of Public Finances (Direction générale des Finances publiques, DGFiP), lists property sales over the last five years, based on notarial deeds (actes notariés) and the land register (cadastre). It is published on data.gouv.fr, free of charge and open to all. To consult it:

  • the data.gouv.fr explorer shows the sales in an area on a map, with the price, date, address and recorded characteristics; it also lets you filter by property type and track changes in prices per m²;
  • Etalab’s older DVF application, still online, lets you search by municipality, cadastral section or cadastral plot.

What DVF shows, and what it does not

For each sale, DVF gives in particular the date, the price (called the valeur foncière), the address, the type of premises, the floor area, the number of main rooms and, where stated, the Carrez floor area (surface Carrez, the legally defined private floor area of a unit in a co-owned building). But the official guide is clear: the description of the property in the notarial deed is not included. There is nothing on the condition of the flat, the view, the floor, the terrace or any works.

Four more points to watch:

  • The time lag. The files are updated twice a year: in April for sales registered with the land registration office (service de la publicité foncière) before 31 December of the previous year, and in October for those registered before 30 June. The latest year is generally incomplete. The data.gouv.fr website also points out that averages taken from DVF do not necessarily reflect the current market.
  • A single overall price. If a flat was sold with a parking space or another ancillary unit, the same price appears on each line: there is no way of knowing the value of the flat alone.
  • A price to interpret. The valeur foncière includes agency fees payable by the seller and any VAT, but not agency fees payable by the buyer, notary’s fees or furniture whose value is stated in the deed.
  • A declared floor area. This is the last floor area declared to the land tax services (services fonciers), which does not always match reality.

2. The impots.gouv “Rechercher des transactions immobilières” service

The DGFiP also offers a free service on impots.gouv.fr, in the online account for private individuals (espace Finances publiques). It is open in particular to prospective sellers and buyers, and to anyone who needs to value a property for an inheritance, a gift or the French real estate wealth tax (impôt sur la fortune immobilière).

Once logged in, you choose an area and a period. The service displays the corresponding sales, including their date, price, cadastral references, address, property type, floor area and construction period, over a maximum of nine years, including the current year. Good to know:

  • only sales that genuinely reflect market prices are displayed;
  • the information obtained is for your personal use only;
  • for an accurate valuation, the tax authorities point out that you need to take the property’s own characteristics into account, on your own responsibility, and possibly seek advice from a professional.

3. The notaries’ statistics

Since 1994, notaries have been feeding databases with the deeds of sale drawn up in their offices: Perval for areas outside the Paris region, including the Alpes-Maritimes, and BIEN for the Paris region (Île-de-France). On immobilier.notaires.fr, they publish the number of sales, the median price per m² and the quartiles, over one to eight quarters. These prices exclude transfer duties (droits de mutation) and are net seller prices (prix net vendeur), excluding furniture and agency commission: they therefore cannot be compared directly with DVF values.

The notaries themselves point out their limits: these statistics are only published when there are at least 20 sales for the chosen period, area and property type; they sometimes cover small volumes, and structural effects (the quality of the properties sold) are not adjusted for. They should therefore be treated with caution.

Property prices in Beausoleil: why averages are fragile

At the level of a municipality, and even more so of a neighbourhood such as the Centre, the Moneghetti or the Tenao, there may be few truly comparable sales over the same period. In a small sample, a few sales of flats with a terrace and an open view, or conversely of studios in need of renovation, may be enough to shift a median.

Why online valuation tools can give different results

An automated valuation tool does not visit your property. It applies its own method to data it has selected (period, area, sales included): results may therefore differ from one tool to another. If it relies on recorded sales, it also inherits their limits: time lag, small samples, overall prices, no information on condition, view, floor or works.

What can affect the value of a flat in Beausoleil

Bordering Monaco, Beausoleil wraps around the slopes above the Principality and offers views from Cap Ferrat to Italy; its stairways have earned it the nickname “Petit Montmartre”. Our page on property in Beausoleil introduces the town and its neighbourhoods.

In a hillside town, two flats of the same size in the same street may not be worth the same price. Points to note include:

  • Proximity to Monaco: the journey to the Principality, on foot or by public transport.
  • The view: unobstructed sea view, partial view or none.
  • Outdoor space: terrace or balcony, its size and orientation.
  • Floor and lift: the floor often affects the view and the light; a high floor without a lift does not suit every buyer.
  • Parking and ancillary space: parking space, garage or cellar, sold with the flat or not.
  • The co-ownership (copropriété, the French system of joint ownership of a building divided into units): condition of the building, level of service charges, works already approved or likely to be needed.
  • Interior condition: recent renovation or work required.
  • The energy performance certificate (diagnostic de performance énergétique, DPE): its rating and its validity. The rules (validity, and the new calculation for electricity in 2026 and 2027) are set out in our article on the mandatory diagnostic reports for selling a flat.

Most of these points do not appear in sales databases: that is precisely the gap between an average and the value of a specific property.

How to use these figures for your flat

  1. Look up DVF sales around your address over several years, keeping only flats.
  2. Set aside sales whose price covers several units, off-plan sales (ventes en l’état futur d’achèvement), whose price may include VAT, and any that seem atypical to you.
  3. Compare with the notaries’ indicators, where they are published for the area, bearing in mind that they are net seller prices.
  4. Note what sets your property apart: view, floor, outdoor space, parking, condition, service charges, DPE.
  5. Have these points assessed against the market by a professional who visits the property.

Our agency, at 10 boulevard de la République in Beausoleil, offers a free, no-obligation valuation of your flat, at our office or at the property.
