Tenant screening SaaS detects bank statement fraud with PDF forensics
Original: Tenant Screening SaaS: Bank Statement Fraud Detection
Short summary
A detailed analysis of how structural PDF forensics can close fraud-detection gaps in tenant screening SaaS platforms, where applicants upload bank statements that bypass stronger signals like Plaid. The article breaks down the layered signal stack (OCR, Plaid, employer verification, credit pulls) and explains why document-fraud detection is one of the cheapest signals to add per applicant. It also covers the asymmetric indemnity exposure from missed fraud, including direct liability, churn, and fair-housing disparate-impact risk.
- •Structural PDF forensics is a cheap, high-value signal for tenant screening pipelines that already use OCR, Plaid, and credit pulls
- •One missed-fraud case can wipe out gross margin on hundreds of clean screens due to indemnity exposure
- •Tightening models to reject fraud raises false-decline rates, creating fair-housing disparate-impact risk
