The French real estate market is going through a period where search criteria are evolving faster than the tools available to buyers. Between new regulatory obligations regarding energy diagnostics and the proliferation of listings across dozens of platforms, identifying a property that truly matches a purchase or rental project now requires more than just a simple search engine by price and size.
Energy diagnostics and real estate portal: what listings don’t always show
The reliability of regulatory information displayed in listings remains a blind spot for many platforms. Since January 1, 2025, energy performance certificates (DPE) issued between January 2018 and June 2021 are no longer valid. A buyer consulting an old listing may therefore find themselves facing an outdated diagnosis, without knowing it.
This validity issue directly affects the quality of the results offered by a real estate portal. If the platform does not filter out listings with expired DPEs, it exposes its users to misleading information. A portal that would automatically integrate this control would offer a concrete advantage over generalist aggregators.
Moreover, the mandatory energy audit has been extended since early 2025 to individual houses and single-owner properties classified as E, in addition to classes F and G. For a buyer, checking on the Veritaxis real estate portal that these documents are indeed present in the listing helps avoid surprises when signing the compromise.
Real estate search filters: beyond price and size
The majority of listing sites offer the same sorting criteria: location, budget, number of rooms, type of property. These filters cover basic needs but overlook parameters that weigh heavily in the final decision.
The DPE ranking is becoming a standalone search criterion. With the phased ban on renting thermal sieves, a rental investor needs to filter directly by energy class to exclude properties that will require renovation work before being rented out.
Other criteria are gaining relevance without being systematically proposed:
- The presence of a collective DPE for condominiums, now mandatory in stages for buildings constructed before 2013, which informs about the overall performance of the building and not just the unit
- The orientation and sunlight exposure of the property, which some platforms are starting to integrate via mapping data, but which remains absent from most search engines
- The actual proximity of transport and shops, calculated in travel time and not just in kilometers, which radically changes the perception of a neighborhood
A portal that structures its data around these parameters facilitates comparison between listings and reduces the number of unnecessary visits.
Artificial intelligence and real estate listings: regulatory transparency in 2026
The growing use of artificial intelligence in the real estate sector raises concrete questions. Since August 2, 2026, the European AI Act imposes enhanced transparency obligations on several uses: agency chatbots must indicate that they are automated, and images generated or edited by AI (virtual home staging, for example) must be identified as such.
This regulation directly concerns real estate portals. A buyer who discovers photos enhanced by AI without mention may feel deceived during the visit. Some professionals believe that virtual home staging helps with projection, while others feel it creates a detrimental gap between the image and the reality of the property.
An innovative portal stands out by its ability to clearly indicate AI-generated content. This transparency, now framed by law, becomes a marker of trust for users comparing dozens of listings.
Comparing real estate portals: what criteria to choose your search platform
The choice of a portal is not limited to the volume of listings referenced. A site that aggregates hundreds of thousands of properties without qualitative verification produces noise, not useful information.
Several elements deserve attention when choosing a platform for a purchase project:
- The frequency of listing updates: a sold property that remains displayed for weeks generates frustration and wastes time
- The verification of regulatory data (validity of the DPE, presence of the energy audit when mandatory, mention of the risk of rental ban)
- The quality of email alerts: receiving targeted notifications on specific criteria, rather than a daily stream of irrelevant properties
- The ergonomics of mobile search, which now represents the majority of real estate listing consultations in France
The relevance of results matters more than their volume. A portal that offers fifty properties that truly match the project is better than an aggregator that displays a thousand with approximate filters.
The available data does not allow for concluding that a single portal model is dominant. However, platforms that cross-reference regulatory data, advanced search criteria, and transparency on AI content meet a growing expectation from buyers. The online real estate market is evolving towards more qualified listings, and the verification of published information now weighs as much as the number of properties referenced in the choice of a platform.
