# Research and data behind the guides

See how this site checks public information, dates claims and records uncertainty about buying a house in Rotterdam.

## How a claim is checked

Pages that include public facts record the date checked, the provider and the reason the information matters to a buyer. Government, municipality and notary pages are used for rules, public services and transaction steps. Editorial judgement is labelled as judgement.

## What the guides keep separate

A neighbourhood description, a planning document and a buyer’s own viewing test answer different questions. A public policy page cannot settle the noise, condition or cost of one address. A national rule cannot calculate a personal borrowing amount.

## Where uncertainty stays

Prices, tax rules, school information, transport changes and building plans can move. Check the date on the page and follow the linked provider when a decision depends on a current figure. The [editorial method](/en/editorial-method/) explains updates, corrections and the difference between public information and editorial judgement.

## Read the research in context

The [city-centre guide](/en/guides/buying-a-house-in-rotterdam-city-centre/) shows how local public information becomes a buyer comparison. The [purchase plan](/en/guides/buying-a-house-in-rotterdam-10-steps/) shows where contract and transfer checks sit in the wider sequence.
