Research and data
See how Taxateur in Rotterdam handles dates, definitions, public information and limits in valuation guidance.
Why dates and definitions matter
A number needs a period, definition, area and method. When a guide discusses home value, it states the source and date when they change the meaning.
Public information
The municipality determines the WOZ value for public purposes. Rijksoverheid explains the WOZ process, including the valuation report and the owner’s questions.
Kadaster provides registered sale information. Its Koopsominformatie page describes available details and timing. A sale price is one observation with a date and property facts.
Evidence in a valuation report
A private valuation works within a purpose and value date. The report should explain property facts, comparable homes, assumptions and the conclusion. A mortgage can add conditions from a lender or NHG.
How the editorial check works
For each guide, the editorial process asks:
- What search question does the page answer?
- Which official source supports each factual claim?
- Which date or definition limits the claim?
- What could make the conclusion differ?
The writer then adds an original comparison or checklist so the page helps a reader act on the information.
Limits
The platform organises public information and explains terms. It does not produce a personal valuation, tax assessment or finance decision. Use the contact form to report a correction or ask about a page.
Next steps
Read the editorial method and open the guide that matches your valuation question. Keep the source date with any number you copy into your own notes.
