The Tire Swing platform

Turn certification packets into structured findings.

Explore the platform
Document intelligence

Tire Swing reads paystubs, W-2s, social-security letters, asset statements, applications, TICS, and lease docs, and pulls the fields a certification actually needs.

Regulation validation

Every extracted value is checked against current HUD, LIHTC, PBRA, HCV, and property-specific rules, with the source context reviewers need to act.

How it works

One certification, end to end.
