A cloud-native URAR appraisal platform built from the ground up for UAD 3.6. Full MISMO 3.6 XML generation, 729-rule validation, AI-powered QC review, automated fee negotiation, AMC quality dashboards, and GSE submission infrastructure — built for residential appraisers, AMCs, and lenders.
Not a retrofit. The Appraisal Cloud Engine was engineered against the GSE specification — every field definition, every validation rule, every XML path traced directly from the published appendices.
Data-driven XML builder mapping 1,701 of 1,798 fields (94.6% coverage) with full XSD schema validation. Every element traced to its specification xPath.
All 729 UAD compliance rules from Appendix H-1 implemented and passing. Real-time advisory validation with click-to-navigate error resolution.
Legal 8.5"×14" PDF matching the Appendix E-1 Style Guide. Carlito typography, conditional sections, photo embedding, and digital signatures.
Claude-powered QC agent reviews every report end-to-end — assigns an A–F grade, flags critical/major/minor issues, provides inline field suggestions, and answers questions via a contextual chat sidebar.
Full AMC order lifecycle — intake, assignment, scheduling, inspection tracking, fee negotiation, revision requests, and delivery. API-driven with webhook callbacks.
SVG-based floor plan drawing with Shoelace area calculation, multi-floor support, area type classification, and GLA computation directly in the browser.
Role-based access for appraisers, reviewers, and administrators. Status transitions, assignments, field-level audit trail, and supervisory cosignature support.
Real-time property lookups via ATTOM Data API — building characteristics, tax assessments, comparable sales search, and FEMA flood zone data.
Complete dual-GSE submission infrastructure. MISMO 3.6 XML, PDF, and images packaged into the required ZIP format with cross-referenced file structure.
Full support for URAR, Appraisal Update, and Completion Report types — each with dedicated forms, XML builders, PDF templates, and DB schema.
Drag-and-drop photo upload with categorization, workfile document management, and integrated report photo bridging across orders and reports.
RESTful Order Intake API with API key authentication, per-key rate limiting, HMAC-signed webhook callbacks, and programmatic order submission.
Four-tab quality oversight hub for AMC admins and reviewers — live SLA tracking with warning/critical thresholds, overdue order alerts, and per-report scorecards with A–F grades derived from completion and validation scores.
Appraisers publish coverage areas, fee structures, and capacity. AMCs run smart match searches by zip/county/state. Fee proposals, counter-offers, and acceptances flow through a full negotiation thread on every order.
