We built TERRABI Immobilier to democratize the housing market across France.
We turn fragmented listings, complex notarial transactions (DVF), and overlooked rent regulations into radical transparency for everyday renters, buyers, and independent advisors.
Find below-market & rent-controlled apartments that actually help you afford the city.
Navigating French real estate can be complex and overwhelming. Listing prices fluctuate, raw transaction archives are difficult to decode, and rent regulations are often overlooked.
Rent is up. Inventory is tight. Traditional portals display endless ads. TERRABI was engineered as an objective data intelligence engine to help you find true market value.
Find the best deals in Paris & across France.
TERRABI Immobilier runs advanced models on real listings to find what's undervalued, overlooked, or underpriced. We analyze price per square meter from official notary sales (DVF), statutory rent control caps, days on market, and dozens of other open data points to find you the best deal in the city — statistically.
Finally, a platform that works for real residents.
No sponsored bias. Pure market intelligence.

How TERRABI Immobilier Levels the Playing Field
Radical Data Transparency & Ground-Truth Valuation (FairScore)
Every apartment is algorithmically compared against actual recorded notary sales on the same street and parcel over the last 5 years. We calculate the exact market discount or overpricing percentage before you make an offer.
Statutory Rent Ceiling Simulator & Verification (Encadrement des Loyers)
Our engine parses the official prefectural rent reference grids in Paris, Lille, Lyon, Bordeaux, and Montpellier. If an advertised rent exceeds the statutory ceiling, we calculate the exact variance, providing renters and landlords with verified regulatory benchmarks.
Absolute Independence & Neutrality
We are not owned by a banking conglomerate or real estate franchise. No broker can pay to inflate an apartment's FairScore. The data is objective, uncompromised, and public.
GDPR-Strict Privacy & European Cloud Infrastructure
Hosted in high-security European datacenters with strict GDPR compliance. Zero invasive ad-tracking pixels, zero third-party data reselling. Your searches, calculations, and alerts belong exclusively to you.
