AI in the mortgage file: choose verifiable source data first
Choose the data route before the AI application
First choose one clearly defined file step in which data is retrieved directly from the original storage location, with the consumer’s consent. NHG describes source data as data that comes directly from the place containing the original information and does not need further processing. That is a useful minimum standard for an AI pilot: do not let the application work from a separate copy whose origin and processing are unclear. The supplied passages say nothing about a specific AI tool, complete file coverage or the quality of individual mortgage advice; the choice is therefore about implementation discipline, not automation as proof of better advice.
Make the advisory software and CRM chain testable
The practical starting point is one process: source data enters the advisory software, an employee verifies the relevant fields, and the CRM receives only the agreed follow-up or contact signal. According to NHG, relevant data can be loaded directly from the source into advisory software when consumer data providers work with advisory software providers; NHG cites greater convenience, less administration and less risk of errors. This is no guarantee of a complete or error-free file, nor does it prove that every CRM integration is appropriate. It does make the decision question concrete: which data flow, which verification and which follow-up may be included for this application?
Treat verification and explanation as part of the process
Automation can make errors systematic; the AFM points out that incorrect use of source data and poor data quality can have adverse consequences for large groups of customers, and identifies testing policies, monitoring and data-quality checks as important. Therefore, for each AI-supported file step, record what was checked, by whom and what was decided afterwards. Use this decision log: for each AI-supported file step, record the original data source, consent/status, responsible reviewer, check performed, deviation identified, and documented follow-up or advisory decision. This ensures an outcome can later be traced back to its source and human assessment. This article does not provide individual mortgage, legal or financial advice and does not replace assessment against the obligations applicable to the specific file, organisation and licence holder.
