How to build a Lease Abstractor Agent

This intelligent workflow transforms complex commercial lease analysis from a manual, hours-long process into an automated, structured extraction system. Users simply upload their lease documents, and the AI systematically extracts critical information across multiple categories.

How It Works:

1. Document Upload & Processing — Users upload lease files (PDFs, scanned documents) which are processed with OCR capabilities to extract readable text.

2. Parallel AI Analysis — Multiple specialized AI analysts work simultaneously to extract different categories of information:

   • Basic Lease Terms — Property name, addresses, square footage, lease dates, tax clauses, insurance and CAM reimbursements, renewal options

   • Maintenance Responsibilities — Detailed extraction of landlord vs. tenant responsibilities for landscaping, structural elements, roofing, painting, doors, locks, and more

3. Intelligent Conflict Resolution — The system applies a clear precedence hierarchy (Addendum > Base Lease > Riders > Exhibits) when terms conflict, ensuring accurate interpretation.

4. Structured Output — Results are delivered as organized JSON with confidence scores and explanatory notes for each extracted data point, making it easy to identify items requiring human review.

Key Features:

• Handles multiple lease term periods (base lease, extensions, renewal options)

• Flags OCR-unreliable sections to prevent hallucination

• Provides confidence ratings (high/medium/low) for every extracted value

• Extracts 50+ data points per lease including property details, financial terms, and maintenance matrices
