Choosing a real estate site for a home project is not just about comparing the number of listings or the free nature of a service. Since 2025, regulatory obligations have changed what a portal must display, and natural language search functions have altered how criteria are formulated. These two developments create concrete gaps between platforms, often absent from usual comparisons.
DPE Compliance and Controls: What Your Real Estate Site Must Display
A decree that came into effect on October 1, 2025, has strengthened the display framework of the DPE in real estate listings. Each listing must now mention the energy class and climate class of the property. Sanctions for non-compliance have been increased for both agencies and publishers.
The DGCCRF has simultaneously intensified its controls on portals and real estate professionals. Listings published without a valid DPE expose their authors to legal action.
For a buyer looking for a house, the consequence is direct. A portal that tolerates incomplete listings obscures the actual energy performance of certain properties. The ability of a platform to filter or flag these listings becomes a selection criterion as crucial as the volume of its catalog.
Consulting a real estate site similar to agorenovation allows access to portals that integrate these regulatory requirements into their standard operation.
Comparison Table of Discriminating Criteria Between Real Estate Portals
Usual comparisons rank platforms based on their general strengths. The table below isolates the criteria that create a concrete gap in the experience of searching for a home.
| Criterion | General Portals (Leboncoin, PAP) | Specialized Portals (SeLoger, Bien’ici) | Aggregators and Proptech |
|---|---|---|---|
| Natural Language Search | Absent | SeLoger: integrated (written and oral) | Advanced chatbots with automatic filtering |
| Systematic DPE Compliance | Variable, frequent listings without DPE | Stricter filtering, possible flagging | Depends on the source of listings |
| Listings Between Individuals | Majority | Minority or absent | Mixed depending on the aggregator |
| Price Estimation Tools | Basic or absent | Integrated with notarial data | Proprietary algorithms |
| Financing Support | None | Partnerships with brokers | Integrated simulators |
A buyer targeting a house with a defined budget and specific energy requirements does not derive the same benefit from a generalist as from a specialized portal. The type of platform determines access to very different functions.
Natural Language Search: A Filter Rather Than a Gadget
SeLoger claims the position of the first French real estate portal to natively integrate a written and oral natural language search into its standard process, according to the Journal de l’Agence and MySweetImmo. Instead of filling out a dozen fields, the user enters a complete query: “4-room house with garden under 300,000 euros near Nantes”.
On the proptech side, advanced chatbots offer comparable interfaces. The overall project (budget, city, number of rooms, neighborhood criteria) is handled in a single interaction. The difference with a classic filter engine is measured in time: formulating a complete project in one sentence significantly reduces the number of pages to browse.
Listings Without DPE: Identifying Portals That Actually Filter
The absence of a DPE on a listing is not simply a technical oversight. It skews the comparison between properties and places the professionals involved in violation of the regulatory framework tightened since 2025.
Three points allow for evaluating the rigor of a portal on this subject:
- The energy class and climate class are visible from the results list, not just in the detailed property sheet.
- A filter allows excluding listings without a DPE or in the process of being completed.
- Old listings without updated DPE are flagged or automatically removed.
No current comparison rates portals on these criteria. However, they determine the reliability of the information on which a buyer bases their visits and offers.
Integrated Financing Tools: An Underestimated Gap Between Platforms
Specialized portals sometimes offer mortgage simulators directly in the listing sheet. Others redirect to partner brokers. Generalist sites, on the other hand, typically do not include any such tools.
For a home purchase, this gap weighs more heavily than for an apartment. The amounts involved are often higher, and the ancillary costs (renovations, connections, soil studies) are more difficult to estimate in advance. An integrated simulator that takes into account notary fees and renovations limits discrepancies at the time of bank assembly.
Aggregators pose an additional problem: the same house may appear multiple times with different prices depending on the source agency. Before relying on an aggregator to compare properties, checking its management of duplicate listings remains a useful reflex.
Selection Criteria for a Real Estate Site for a Home Project
Volume of listings, ergonomics, free access: these classic criteria remain relevant but are no longer sufficient to differentiate platforms. For a home project, five additional points deserve systematic verification:
- DPE compliance is displayed and filterable directly in the search results.
- The search accepts complex queries combining budget, location, and property characteristics.
- A financing simulator integrates the ancillary costs specific to individual houses.
- Duplicate listings between agencies are identified or merged.
- Customer reviews of partner agencies are accessible from the property sheet.
The best real estate site for a house is not the one that displays the most listings, but the one that allows for cross-referencing the most reliable criteria in the least amount of time. Regulatory developments on the DPE and the emergence of natural language search create a measurable gap between platforms, which rankings based solely on the volume of listings do not reflect.
