PropertyHubUnified valuation workflows without replacing existing systems
The Challenge
PropertyHub, an REA Group company, powers lending decisions and valuation workflows across the Australian real estate market. It was first launched and used by Commonwealth Bank (CBA), and building it for a high-volume lending environment meant confronting the friction many established companies live with.
- Data everywhere, no single source of truth.Ordering and tracking property valuations involved manual, disconnected processes. The goal was to bring them into a single connected space for bankers and mortgage advisers.
- IT investment isn’t paying off.Established internal financial infrastructure had to keep working. The new solution needed to sit between modern third-party data providers and existing systems, getting more from them rather than replacing them.
- Many digital transformations, little to show for them.A new platform would only matter if it changed results at scale: over 10 million property records, more than 1 million monthly updates, and tens of thousands of active professional users, especially during peak weekend auction periods.
The Solution
ToolTwist built a full-stack solution on the ToolTwist Framework, connecting existing systems and data into one workflow.
- Unified valuation workflow.Professionals order, track and receive valuations in one dashboard, replacing disconnected manual steps and drastically reducing administrative turnaround times.
- Intelligent backend orchestration.The backend receives user queries, fetches real-time property intelligence and Automated Valuation Models (AVMs) from the RP Data marketplace, and applies the bank’s own business rules.
- Dynamic enterprise frontend.Built with the ToolTwist Framework’s templating system, the interface quickly generates data-rich property reports and dashboards that stay responsive and lightweight.
- Optimised data pipeline.The framework acts as a data refiner, turning heavy property records from external sources into optimised packets so the experience stays fast, even with complex datasets.
ToolTwist’s Role
As the primary technology partner, ToolTwist took ownership of the entire development lifecycle within a high-compliance environment.
- Full-stack development.We built the frontend and backend together on the ToolTwist Framework, keeping the interface and the underlying data layer fully aligned.
- API integration and mapping.We developed secure connectors to the Cotality Commercial API and RP Data streams, translating complex third-party data structures into the layouts lending staff need.
- Security and compliance hardening.We met rigorous industry security standards, including advanced authentication and comprehensive audit logging for every valuation request.
Impact
- One connected workflow.Valuations are ordered, tracked and received in one place, giving lenders a single trusted view instead of scattered manual processes.
- Faster, more accurate lending.Reduced administrative turnaround lets professionals process applications with greater accuracy and speed.
- More value from existing systems.PropertyHub works alongside established financial infrastructure and third-party data rather than replacing them.
- An investment that lasted.The technical foundation has let the platform scale and evolve with market demands for well over a decade, avoiding costly rebuilds.
