Caveats: this measures what sellers choose to highlight, not real equipment. Feature fields are filled on 85.7% of listings and labels aren't normalized, so 1.2% is a floor. Snapshot Aug 17, 2026, active for-sale flats in France, deduplicated across 1,500+ sources.
The catch: the law kicks in May 20, but the government admits the full teleservice won't be live until H2 2026.
So the obligation arrives before the tool. Fines up to €20K for false declarations.
This is what data centralization in France actually looks like in practice.
A seller listed at $600K because "that's what Zillow said."
19 days. 4 showings. 0 offers.
Real market price? $549K. A $51K gap from trusting a single data source.
