Overview
Home appraisals are central to HUD's housing programs, and appraisal data has to move accurately between the parties that submit it and the HUD systems that rely on it. Iron Brick architects delivered a complete, complex integration of home appraisal data, built as governed, reusable APIs with validation, security, and monitoring at every step.
The challenge
- Appraisal data came from multiple external parties and had to reach several HUD systems, each with its own formats and rules.
- Appraisals are detailed, structured documents, so the integration had to handle complex data and validate it before HUD systems used it.
- Property and borrower information had to be protected throughout, and every exchange had to be traceable.

The Solution
End-to-end integration design
One integration architecture covering the full appraisal flow, from receipt through validation to delivery into HUD systems.
API contracts first
Each interface defined as a RAML or OpenAPI contract before code, so teams could build and test in parallel.
Validation and transformation
Appraisal data checked for structure and business rules, then transformed into the formats each HUD system expects.
Security by design
Authentication, authorization, and encryption on every exchange, with sensitive fields protected.
Error handling and reprocessing
Failed or invalid submissions captured, reported, and reprocessed instead of being lost.
Monitoring and automated delivery
CI/CD pipelines with automated tests, plus logging and monitoring so operations teams could trace every appraisal.
Results
Complete integration
The full appraisal data flow runs through one governed integration layer.
Trusted data
Validation means HUD systems receive appraisal data that meets their rules.
Traceable exchanges
Every appraisal can be followed from receipt to delivery.
Reusable APIs
The same APIs serve new applications and reports without new point-to-point links.
