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 explains updates, corrections and the difference between public information and editorial judgement.
Read the research in context
The city-centre guide shows how local public information becomes a buyer comparison. The purchase plan shows where contract and transfer checks sit in the wider sequence.
