About this app
Before a viewing, before making an offer, before signing: take a few seconds to analyze the address.
ImmoRisk compiles in a clear fact sheet everything a buyer needs to know about a property in France — natural and technological risks, surrounding nuisances, the actual market price in the area, and an estimate of the room for negotiation. All based on official public data, with no account required and no advertising.
WHAT THE APP DOES
Address Risk Scan
More than twenty natural and technological risks are reviewed: flooding, rising groundwater, coastal erosion, seismic activity, landslides, clay shrinkage and swelling, forest fires, radon, classified facilities for environmental protection (ICPE) and Seveso sites, and underground cavities. For each risk, a fact sheet explains the phenomenon, its potential financial impact, points to check on-site, and useful arguments to use with the seller. History of Natural Disasters
The app indicates the number and dates of officially recognized natural disaster decrees in the municipality — the area's concrete history. Nuisances and Environment
Beyond regulated risks, ImmoRisk identifies zoning regulations in the Local Urban Development Plan (PLU), nearby cell towers, exposure to aircraft and ground noise, polluted sites and soils around the address, high-voltage power lines, and wind turbines.
Area Prices
The average price per square meter is calculated based on five years of notarial transactions (DVF database). A scale positions the property between the lower and upper end of the local market. Filters for houses or apartments, adjustable radius, and recent sales can be viewed on a map.
Negotiation Simulator
Based on the listed price, surface area, and Energy Performance Certificate (EPC) rating, the app estimates a negotiation margin broken down into three factors: the price premium compared to the market, the impact of the EPC rating, and the costs associated with risks. You select your renovation projects, adjust the amounts with your own quotes, and obtain a ready-to-copy or share offer brief. Complete PDF Report
Your analysis is exported as a two-part PDF file: your personal report to prepare for the purchase, and a section to present to the seller or agent. Market price, risks, costs, and supporting arguments are included.
PUBLIC AND OFFICIAL DATA

USAGE
The first three analyses are free: risks, nuisances, market prices, and quantified negotiation margin are displayed. Detailed leverage points, the complete rationale (the free version shows an excerpt), the mapping of all transactions, and the PDF report require a package: 5 analyses (€3.99), 20 analyses (€9.99), or 75 analyses (€29.99). No subscription is required. Once unlocked, your access remains free: you can return at any time without additional cost.
IMPORTANT INFORMATION
ImmoRisk covers mainland France and the French overseas departments and territories. Estimates are indicative only: they do not constitute professional advice, a real estate appraisal, or financial guidance, and do not replace mandatory diagnostics (risk assessment – ERP). Internet connection required.
