The actual selling price of a house corresponds to the amount recorded in the notarial deed, which is then transmitted to the tax administration. This amount, called net seller price, differs from the price displayed in real estate listings: it excludes notary fees and does not reflect the negotiations that occurred between the initial offer and the final signature. Several public tools now allow access to this data without spending a dime.
What the DVF price actually includes and excludes
The Demande de Valeurs Foncières (DVF) database lists transactions from notarial deeds. The amount recorded is strictly the price paid by the buyer to the seller, excluding ancillary costs.
This distinction has direct consequences on data interpretation. When a house appears at 280,000 euros in DVF, the buyer has actually paid a higher amount once notary fees are added. Conversely, if the seller paid an agency commission included in the price, it is reflected in the DVF amount without being isolated.
Three elements are systematically absent from DVF data:
- The notary fees (transfer duties, fees, expenses), which represent a significant part of the total cost for the buyer
- The details of the agency commission, even when it is included in the selling price displayed in the deed
- Any negotiated work in exchange for a price reduction, which does not appear anywhere in the database
To estimate a property in your area, you can check prices on Ventes Immo to cross-reference the results with official data and refine your understanding of the local market.
Time lag of DVF data: why the latest sale does not appear
A point rarely anticipated by individuals concerns the delay between the signing of a deed and its publication in DVF. The database is not updated continuously.
Since 2026, the update schedule has stabilized around two annual publications. The April update adds all sales from the previous year. The October update covers the first half of the current year.
This process creates a structural lag of at least three to six months. If your neighbor sold their house in March, the transaction will not appear until October at the earliest. For a sale signed in September, you will have to wait until April of the following year.
This delay is not a malfunction. It results from the administrative circuit: the deed goes from the notary to the land publicity service, and then the data is aggregated and anonymized before publication. No public tool provides access to real-time prices.
Reading DVF transactions without distorting your estimate
Accessing prices is not enough. A house sold for 350,000 euros on your street does not mean that yours is worth the same amount. Several parameters radically alter the comparison.
Surface area and type of property in the data
DVF indicates the surface area of the property and the number of rooms, but not the general condition, quality of materials, or presence of recent renovations. Two houses of identical size on the same street can have a considerable price difference if one has been renovated and the other has not.
The price per square meter remains the most useful indicator for comparing properties of different sizes. Divide the selling price by the surface area indicated in DVF to obtain this ratio for each transaction.
Median price rather than average price
The average price of a neighborhood can be skewed by a single exceptional sale. The median price, which divides transactions into two equal halves, provides a more reliable picture of the local market. The data explorer on data.gouv.fr displays this median price per square meter at the national, regional, and municipal levels.
For practical use, isolate transactions involving houses comparable to yours: same size range, same geographic area, same time period. Five to ten recent transactions are sufficient to identify a trend.
Notarial data and DVF: two complementary sources not to be confused
The notaries’ databases (accessible via the site notaires.fr) and the DVF database draw from the same source, notarial deeds, but present the information differently.
DVF offers raw access, transaction by transaction, on an interactive map. The notarial data aggregates prices by sector and property type, with statistical indicators such as quarterly trends. DVF shows the details, while notarial data shows the trend.
Both tools share the same limitation: the time lag. Notarial data experiences a comparable delay, sometimes slightly shorter in certain segments because notary chambers can publish quarterly indices before the semi-annual DVF update.
For a buying or selling project, consulting both in parallel allows you to verify whether a price spotted in DVF falls within the local market range or if it constitutes an anomaly.
Limitations of free tools for low transaction volume areas
In rural municipalities or neighborhoods where few houses change ownership each year, DVF data loses statistical relevance. Three or four sales over five years do not provide a reliable market price.
In these cases, notarial data aggregated at the level of the district or intercommunal area offers a better reference. An estimate by a local professional remains a relevant complement, as they have knowledge of recent transactions that have not yet been integrated into public databases.
The actual selling price of a house is never an isolated figure. It is a net seller amount, published with several months of delay, that only makes sense when compared to similar transactions within a restricted geographic area. Keeping these three parameters in mind helps avoid the most common interpretation errors.
