Methodology

CheckBuurt.NL pulls eight official Dutch sources together into one readable verdict: is this home and neighbourhood worth viewing? On this page we explain which sources we use, at what level each figure applies, how the verdict is produced and — just as importantly — what the report is not.

Sources and the level at which they apply

Not every figure applies to a single house. The energy label and year of construction are property-specific; crime, liveability and demographics apply to the neighbourhood, not to the individual home. For each item we state the source and the resolution, so you know how precise a figure is.

CBS — Key figures districts and neighbourhoodsPopulation, housing type, owner/rental split, urbanity and WOZ context.

Neighbourhood / municipality

Leefbaarometer (BZK)Liveability score across five dimensions: housing, amenities, the physical environment, social cohesion and nuisance/insecurity.

Neighbourhood

Politie — registered crimeThe number and type of registered offences per year, with the top categories.

Neighbourhood

RIVM / Atlas LeefomgevingAir quality, noise, greenery and climate/environmental risks.

Location (coordinate)

DUOPrimary schools within walking and cycling distance, with distance and direction.

Address (radius)

EP-Online (RVO)The property's definitive energy label and energy index.

Address / BAG object

PDOK / BAG (Kadaster)Address resolution, year of construction, floor area and use of the property.

Address / BAG object

Address resolution

We turn a postcode and house number, via PDOK/BAG, into an exact BAG object with coordinates and neighbourhood and district codes. If that cannot be done unambiguously, we show no report rather than a guess. The same goes for each item: if a neighbourhood does not appear (separately) in a source, we honestly say "no data available" — that does not mean there is, for instance, no crime, only that the source does not report this neighbourhood separately.

The verdict (AI verdict)

Once the figures have been gathered, a language model summarises them into a neutral, factual verdict: a short characterisation, strengths and risks, a profile fit (for example family, first-time buyer or expat) and concrete questions for the viewing. The model reasons only on the basis of the figures supplied — it invents no prices, names or facts and gives no buying advice. If the verdict cannot be produced reliably, we leave it out rather than show something that is wrong.

What this report is not

Not a valuation or appraisal of the home.
Not buying or investment advice.
Not a structural survey or foundation inspection.
Not a guarantee: sources can be out of date or incomplete. The report is a tool to help you look more closely and ask better questions — not a substitute for your own research or professional advice.

Currency of the data

Source data is refreshed periodically as soon as the source holders publish new editions. We show the most recent available year per source.
