Verification Methodology

Only verified partners publish on EstateAL. Before a partner is approved we check who they are, and they accept our published partner rules. A partner may only list a property they have the right to market, and must be able to show it — as owner, exclusive agent, or with written authorisation from the owner (a title, an agency agreement, an owner's written permission, an exclusive mandate, or a developer mandate). This keeps out the single most common source of bad listings: property advertised by someone with no right to sell it.

Every submission passes a human review before publication — it moves through submitted, under review and verified before it can be published. We check the listing against our standard: at least eight good photographs, the ownership or authorisation basis, and accurate core facts (area, price, location, status). We may ask a partner to correct a listing, or decline it, always with a reason. Demonstration and test entries are kept strictly internal and are never published.

Not all sources are equal, and we treat them accordingly.

For legal, tax and risk facts we rely on authoritative, primary sources: national cadastres and land registries, tax authorities, the European Commission, Eurostat, and comparable institutional bodies. We do not take legal or risk facts from marketing pages.

For prices and yields we rely on recorded market evidence and independent statistics — registered transactions, national statistics offices (for example SURS, DZS, ISTAT) and comparable institutional data — cross-checked against asking-price signals, and never a seller's or developer's projection taken at face value. We discount optimism rather than repeat it, and present figures as a range by zone rather than a single cherry-picked number.

Our own data — database scores, partner-supplied information, demand signals — sits on top of, never in place of, the above.

Behind the site is a knowledge base with a strict provenance rule. A fact proposed by our AI is marked as such and is not shown on public, trust-bearing surfaces. It becomes publishable only after a person reviews it and marks it verified. Only human-verified facts reach public pages, structured data, and the confident answers of the AI Advisor. This is how we prevent a plausible-sounding guess from ever being presented as a checked fact.

Information decays: prices and yields age within months, tax and legal rules within a year, EU-status facts change with events. Every fact we hold carries its source and the date it was last verified. When a fact ages, we lower its weight and flag it rather than present stale data as current. Units and currency are normalised once — €/m², and gross versus net yield defined explicitly — so comparisons are like-for-like.

We never show a single optimistic number. Every yield is a pair: a realistic baseline we stand behind on current data, and a conditional upside whose conditions are named (for example a top-tier short-let operator or an extended shoulder season). Where a listing has its own verified figures we show those; otherwise the card shows the range for its zone, marked indicative, until a verified figure exists. These are estimates, not guarantees; the sources behind them are set out in the source hierarchy above.

We do not ask the buyer to verify the law alone, and we do not pretend to replace a notary. The exact price, availability, ownership and legal status of a specific property are confirmed for that property, as part of the transaction, together with the seller, the regional partner and the relevant local professionals, and completed through the competent notary and land registry. EstateAL coordinates this process and keeps it transparent; it does not act as a legal guarantor. No one should ever transfer money on the basis of a listing alone — a genuine purchase always involves viewing the property, inspecting the documents, and completing before a notary.

What must be checked differs by asset class, and our process reflects that. For homes — apartments, villas, chalets (our current focus) the emphasis is ownership, encumbrances, permits and accurate presentation. For land, it extends to zoning and permitted use, building rights, utilities and access. For commercial property, to tenants, leases and income. For long-term residential and commercial rental, to the applicable tenancy regulation. As we open these categories, this page will describe the specific checks for each.

We currently cover five countries — Slovenia, Croatia, Austria, northern Italy and Montenegro — across two regions, the Alps and the Adriatic. Verification reduces the risk of a wasted trip or a misleading listing; it does not remove the buyer's own due diligence on the transaction, and it is not investment, legal or tax advice. Where a matter is genuinely unsettled — for example legislation under debate — we say so plainly rather than fake certainty.
