Due to increasing (inter)national regulations, real estate professionals spend more and more time on investigations. Consequences are, for example, that valuation reports have to meet an incredible number of obligations and lots of information is needed for the successful purchase and sale of houses. In short, these are time consuming processes. Our passionate developers have therefore developed a number of APIs that enable you to receive all the necessary information in a fraction of a second. From proofs of ownerships, mortgage statements and WOZ values ​​to cadastral maps, BAG statements, neighborhood information and more! This does not only make a valuation process incredibly efficient, you also meet all requirements and you can easily get a grip on trends and developments within the housing market.

Save time and gain insights

More and more rules have emerged regarding the valuation process. As an appraiser, you therefore benefit from having all the mandatory information available quickly. This way you can save time and give your services a quality boost. In addition, our APIs are also relevant for platform developers and investors. By enriching systems with the housing information, you will gain new insights and you get a grip on trends and developments within the housing market. In this way you can, for example, easily determine investments returns.
