ING Deutschland and Interhyp launch 30-minute digital mortgage approval
ING Deutschland and Interhyp Group have introduced "Instant-Baufi," a fully digital mortgage process offering binding loan decisions within a maximum of 30 minutes.

Frankfurt am Main/München – ING Deutschland and Interhyp Group have launched "Instant-Baufi," a new, significantly accelerated mortgage financing service. Through Interhyp's baufi.NOW platform, customers can now submit and process applications for existing property financing entirely digitally. The service provides customers with a binding loan decision from ING within a maximum of 30 minutes.
The streamlined process substantially reduces customer effort, requiring only an energy performance certificate. Documents typically needed, such as salary slips and floor plans, are no longer necessary as relevant data is captured digitally and automatically checked. While advisors guide the process, the customer confirms the data before submission.
"Instant-Baufi" is the result of a joint innovation project, enabling a continuous digital financing process in Germany where checks and decisions take minutes instead of days. This establishes a new benchmark for speed and quality in mortgage financing, offering customers early and reliable decision-making certainty.
A key component is the AI-powered automated property data check, which uses address information from public sources to create a digital twin of the property, replacing manual document review. Creditworthiness is assessed via a digital account check, with customer consent, which automatically identifies regular income and equity.
ING and Interhyp anticipate that initially, 15–20% of mortgage applications submitted via Interhyp will be processed as "Instant-Baufi," with plans to increase this share. While initially direct between ING and Interhyp, the baufi.NOW platform is designed for broader use by other banks and sales partners in the German mortgage market.
