You just learned that the neighboring house has been sold, and the first question that crosses your mind concerns its price. This curiosity is legitimate, and especially useful: knowing the price of a house sold in your neighborhood allows you to estimate the value of your own property or to calibrate a purchase offer. The good news is that these real estate sales data have been public in France for several years.
Time Lag of DVF Data: What Transparency Doesn’t Tell You
Most guides direct you to the DVF (Demandes de Valeurs Foncières) database to check the prices of real estate transactions. Few specify a detail that changes the interpretation of the results: the published prices are about six months behind the actual sale.

This delay is explained by the administrative process. The notary records the deed, the Direction Générale des Finances Publiques (DGFiP) compiles the data, and then publishes them during semi-annual updates in April and October. If you are looking for the price of a house sold in January, you probably won’t find it until the following October.
This lag has a direct consequence on your estimation. In a market where prices move quickly, both up and down, the latest visible transactions may reflect a context that no longer exists. Keeping this delay in mind prevents you from basing a purchase or sale decision on outdated data.

To know the price of a sold house with the maximum context, you need to cross-reference the mutation date displayed in DVF with the actual period of the local market.
DVF and DVF+: What Information on the Price of a Sold House
You may have heard of DVF without knowing that there are two versions of this database. The historical version, accessible via the Etalab application, provides basic information: address, mutation date, selling price, area, and type of property.
What DVF+ Adds
Since 2022, the DGFiP also disseminates DVF+, which includes technical variables from the fiscal cadastre (MAJIC database). Specifically, you can find more detailed elements about the building’s consistency and certain comfort criteria. These details help to better understand why two houses sold on the same street display very different prices.
Several specialized portals take this enriched data and display it on interactive maps with search filters. The difference in ergonomics is notable: on the Etalab application, you have to navigate manually on the map of France without being able to type an address. Third-party tools allow direct searches by street or municipality.
What Is Missing in All Public Databases
No DVF database contains the actual condition of the property at the time of sale. A house sold after complete renovation and a house sold as-is appear the same way. The gross price per square meter does not reflect the actual quality of the property. This is the structural limit of any public data on real estate transactions.
- Historical DVF: price, address, area, type of property, mutation date
- DVF+: same data plus technical variables from the cadastre (building consistency, comfort elements)
- Neither database: property condition, work done, quality of finishes, energy performance at the time of sale
Cross-Referencing Sources to Validate the Price of a Sold House
Relying on a single source of information about the real estate market exposes you to distorted conclusions. You look at a DVF price, but without context, that figure remains silent.
The Patrim Tool from the Tax Administration
Accessible from your personal space on impots.gouv.fr, Patrim allows you to consult recorded real estate sales in your area. Its advantage over DVF is that Patrim displays more precise search criteria, such as the construction period or the number of rooms. Access is free but limited to personal use (estimating your own property or preparing for a transaction).
The Concrete Role of a Local Real Estate Agent
A professional in the field has knowledge that databases do not capture. They know that a house was sold below price because the seller was in a hurry, or that another reached a high amount thanks to a south-facing garden. The human context of the sale completes the raw data.
You do not need to sign a mandate to ask questions. Most agents willingly share recent price ranges during an initial exchange, especially if you are a potential seller.
Online Estimation and Real Price: Understanding the Gap
Online real estate estimation tools are multiplying. They calculate a theoretical value by cross-referencing public data (DVF prices, location, area) with statistical algorithms. The result gives a ballpark figure, not a guaranteed selling price.
Why this gap? Because the real price depends on factors absent from the algorithms: the emotional state of the buyer, the pressure of the local market at that moment, the quality of negotiation, or the presence of uncharted nuisances.
- An online estimation reflects an average statistical price, not the specific value of your house
- The price displayed by a seller in an ad is not the final selling price (negotiation can represent a significant part)
- DVF data shows the price recorded by the notary, agency fees sometimes included, sometimes not
Comparing an algorithmic estimation to the DVF price of a similar property in the same neighborhood remains the most reliable method to position yourself. But this comparison is only valuable if the properties are truly comparable in area, condition, and precise location.
The price of a sold house is never an isolated figure. It is a data point that takes on meaning when you know the publication delay, the limits of the consulted database, and the local context of the transaction. Consulting DVF or DVF+ is a good starting point, provided you do not stop there.
