The Opportunity
Lease abstraction costs $75-150 per lease when outsourced, takes 3-5 business days, and often requires multiple rounds of corrections. With AI, you can do it in-house for $15-20 per lease equivalent cost—and get results in hours, not weeks.
The Lease Abstraction Workflow
Step 1: Document Preparation
Gather all relevant documents for each lease: base lease, amendments, extensions, side letters, estoppels. Convert to clean, searchable PDFs if needed.
Step 2: Define Your Extraction Template
Standard Extraction Fields
- Tenant legal name and trade name
- Premises description and square footage
- Lease term: commencement, expiration, any extensions
- Rent schedule: base rent, escalations, percentage rent
- Operating expense structure: NNN, modified gross, gross
- CAM charges and caps
- Renewal options: terms, notice requirements, rent determination
- Termination rights: early termination, kick-out clauses
- Assignment and subletting provisions
- Security deposit and guarantees
Step 3: Run the Extraction
Upload the lease documents to your AI tool and request structured output matching your template. For best results, upload the complete lease package and ask AI to reconcile any conflicts between the original lease and amendments.
Step 4: Verify and Refine
Check dates, dollar amounts, and rent calculations. This verification step typically takes 10-15 minutes per lease compared to 2+ hours for full manual review. AI handles the volume; humans ensure accuracy on critical terms.
Current Options Compared
| Approach | Cost/Lease | Turnaround |
|---|---|---|
| Outsourced abstraction | $75-150 | 3-5 days |
| In-house manual | $100-200 (labor) | 2-4 hours |
| Specialized software | $10K-50K/year | Variable |
| AI-assisted | $15-20 | 15-30 min |
Portfolio Analysis
Once you have abstracted lease data, AI enables portfolio-level analysis that would be impractical manually:
- Identify all leases expiring in next 12/24/36 months
- Flag below-market rents based on comparable data
- Calculate rollover exposure by tenant, building, or vintage
- Identify common lease provisions across portfolio
- Generate reports for lenders, investors, or internal review
Property Due Diligence
Beyond leases, AI accelerates other DD document analysis:
- Environmental reports: Scan Phase I/II reports for flags and RECs
- Title documents: Identify easements, restrictions, encumbrances
- Surveys: Extract key findings and exceptions
- Financial statements: Normalize operating data across properties
Speed as Competitive Advantage
In competitive acquisition processes, having lease abstracts in days instead of weeks can be the difference between winning and losing deals. The cost savings are real, but the speed advantage often matters more.
When AI Isn't Enough
Some lease situations still require significant human expertise:
- Ground leases with complex rent reset provisions
- Build-to-suit leases with extensive exhibits
- Subleases requiring analysis of master lease terms
- Synthetic leases or sale-leaseback structures
AI handles the volume; expertise handles the complexity.
