All the data that’s processed by Walter Living is imported from public sources, such as the Kadaster, CBS, RIVM, Rijksdienst voor het Cultureel Erfgoed, Rijksdienst voor Ondernemend Nederland, KCAF, and Open data Overheid. 

We check all these data sources (and a few more) to be able to paint an accurate picture of the price trend of a house. We use the data to calculate other things as well, such as a renovation budget, the strength of the local housing market and we can even give you the best bidding strategies.

Since we use data from the entire country, we have the all the info a local realtor has and more. We refresh our data every day to make sure you’re always looking at the most recent numbers.
