The French real estate market remains active, with several hundred thousand transactions recorded each year in the old sector. Since January 1, 2025, properties classified as G in the energy performance diagnosis (DPE) can no longer be subject to a new rental lease. Properties classified as F will follow in 2028, and those classified as E in 2034.
In this context, searching for real estate online is no longer just about browsing listings. The platform used determines the relevance of the results, the regulatory compliance of the displayed properties, and the time spent before finding a suitable option.
Real estate search filters: what separates a useful portal from a simple catalog
Most real estate portals offer basic filters: area, number of rooms, location, budget. These criteria were sufficient a few years ago. Today, they allow properties that do not match the actual project of the buyer or tenant to slip through.
A filter by energy class has become a minimum requirement. A property classified as G can no longer be legally rented since January 2025. If the platform does not allow excluding these properties, the tenant risks wasting time on listings that will not lead to a rental, or worse, signing a non-compliant lease.
Specialized platforms stand out by the granularity of their criteria. Some allow filtering by estimated rental yield, proximity to a specific public transport option, or type of co-ownership. Others integrate personalized alerts that send new listings matching a defined profile.
To explore available listings with this type of targeted approach, the site indiz.fr immobilier aggregates properties by applying filters suited to current market criteria.
Non-compliant real estate listings: what platforms do not always verify
Displaying a listing on a recognized portal does not guarantee its compliance. In areas subject to rent control, platforms do not systematically check the legality of the published listings.
The reference rent, set by a prefectural decree in the relevant cities, must be included in the listing. In practice, this mention is often absent or incorrect. A tenant who does not verify this ceiling themselves risks paying a rent higher than the maximum allowed.
Checks to perform yourself before contacting a advertiser
- Compare the displayed rent with the increased reference rent published by the prefecture of the relevant city, taking into account the area, number of rooms, and neighborhood.
- Check that the DPE is mentioned and that the energy class legally allows for rental (class F or better for a lease signed in 2025).
- Ensure that the advertiser does not request any payment before the visit or signing of the lease, which remains a frequent fraud signal, even on established portals.
- Check the consistency between the photos, the announced location, and the requested price. A clear discrepancy between these elements justifies moving on to the next listing.
Field feedback varies on the actual ability of portals to detect fraudulent listings. Some have implemented identity verification systems for advertisers, while others rely on post-reporting by users.
DPE and regulatory calendar: concrete impact on online supply
The gradual ban on renting thermal sieves is changing the very structure of the visible supply on real estate platforms. Properties classified as G have already been removed from the legal rental market. This contraction of supply directly affects search results.
For an investor in rental property, this data changes the analysis. A property classified as F, acquired today without renovation work, will no longer be rentable starting in 2028. The platform that displays this information clearly, by cross-referencing energy class and regulatory deadline, provides a value that generalist portals do not yet systematically offer.
The schedule set by the Climate and Resilience law is as follows:
- Since January 2025: prohibition on renting properties classified as G for new leases.
- From 2028: extension to properties classified as F.
- From 2034: extension to properties classified as E.
An investor who does not filter by DPE risks buying a property that cannot be rented in the short term. Specialized platforms are beginning to integrate this parameter into their recommendation algorithms, but the available data does not yet allow for a conclusion that this feature is widespread.
Comparing real estate platforms: concrete criteria beyond the volume of listings
The common reflex is to choose the portal that displays the largest number of listings. This logic has its limits. A high volume of listings without precise filtering produces noise, not relevance.
Three criteria deserve to be evaluated before committing to a platform:
The first is the freshness of the listings. A property published for several weeks without updates is probably already sold or rented. Platforms that display the date of the last modification and automatically archive inactive listings save time.
The second concerns transparency on prices. Some portals display the price per square meter of the neighborhood, agency fees, or the amount of co-ownership charges. Others limit themselves to the total price, which complicates comparisons between properties.
The third pertains to the quality of the mobile interface. The majority of real estate searches are conducted from a phone. A slow application, difficult-to-access filters, or photos that do not load effectively eliminate the platform, regardless of its catalog.
The market for real estate platforms is evolving towards greater specialization. Generalist portals retain their usefulness for an initial broad sweep. Specialized tools take over when the project becomes clearer and the criteria become more technical, particularly regarding energy and regulatory issues. Cross-referencing multiple sources remains the most reliable method to avoid missing out on a property that meets expectations and complies with current regulations.
