Official OMI prices and sales volumes by zone (Agenzia delle Entrate), turned into interactive maps — plus a tool to score any immobiliare.it listing against the real value of its zone. Built for foreign buyers investing in Italy and agents selling Italian property abroad.
Every covered city ships as three linked map views, loaded live from this project's open data.
The one-screen summary of a city's market — ideal for briefing a foreign client fast.
Where prices are highest and where demand is actually moving, zone by zone.
Which zones combine fair price, liquidity and momentum — ranked for investors.
Open data dashboards — no login, no build step. Florence includes the full metropolitan-zone breakdown and is wired to the deal-scoring tool.
Open dataset also covers Genova, Napoli and Torino (market data only — interactive dashboards in progress).
The hard question for any buyer: "€X for this apartment — is that cheap or expensive for this exact street?"
You browse immobiliare.it in your own browser, click a bookmarklet, and a small local server places the listing in its OMI micro-zone, compares the asking price to the official €/m² for that zone, and returns a 0–100 score (STRONG BUY → AVOID).
No automated crawling, no anti-bot circumvention, no headless browser — the tool only reads pages you are already viewing, and stores them only on your own machine. Statistically rigorous engine with 57 passing tests.
Code & methodology: deal-score/ on GitHub. Scoring is calibrated for the Florence metro area.
