What TwinTC™ Does
Every File. Every Time.
- Audits purchase agreements for missing signatures and initials
- Flags contingency dates that conflict with close of escrow
- Catches inconsistent buyer and seller names across all documents
- Identifies missing disclosures before they become a problem
- Tracks deadlines and sends proactive reminders
- Checks document consistency across the entire transaction file
- Provides licensed broker review on every completed audit
- Returns a clear audit report within 24 hours
No document generated. No forms created. TwinTC™ audits what your agent already produced — and makes sure it's right before it goes anywhere.
The workflow
The whole transaction on autopilot — RPA to close.
TwinTC™ isn't a scanner — it's your digital twin. It acts on your behalf using your preferred vendors, your tone, your timeline. And every step is reviewed by a human broker before it leaves your hands.
- 01
Drop the whole file
RPA, TDS, SPQ, AVID, NHD, HOA docs, lead-paint, addenda — drag the entire transaction into the deal room. PDFs, scans, anything.
- 02
Audit every disclosure
AI checks every required C.A.R. form for missing initials, signatures, dates, and timeline conflicts — then a licensed CA broker reviews and co-signs.
- 03
Auto-draft escrow
Pre-written email to your Title Officer with the executed RPA and addenda attached — the forms escrow actually needs to open the file. Disclosures stay with you until contingency removal. Review, hit Approve & Send.
- 04
Run the transaction
Inspections booked, contingency dates tracked, disclosures chased to signature — through close of escrow.
Real License. Real Experience.
Not a Bot. A Broker.
Every TwinTC™ audit is reviewed by Cessna Barrett, California licensed real estate broker since 2000. DRE License 01281555. 27 years of transactions, compliance, and knowing exactly what to look for.
When your file comes in, a real licensed professional reviews it — not just an algorithm. That's the difference between a tech tool and a defensible audit.
