Lease abstraction time varies significantly depending on the method and document complexity.
Manual Abstraction Timeline
A trained US-based paralegal or lease abstraction specialist takes 4 to 8 hours per lease:
- Document review (1.5-2.5 hours): Reading the full lease, identifying all relevant provisions, cross-referencing exhibits and addenda
- Data entry (1-2 hours): Populating the abstract template with extracted values
- Quality review (30-60 minutes): Senior reviewer checks accuracy on high-stakes fields
For offshore abstraction services, turnaround is typically 1 to 3 business days per lease, with total labor running 2 to 4 hours per document at lower hourly rates.
AI Abstraction Timeline
Purpose-built AI lease abstraction tools process each lease in 5 to 15 minutes:
- AI extraction: AI reads the PDF and extracts 126 structured fields as part of the 5-15 minute processing workflow
- Confidence scoring: Per-field confidence calculation (a few seconds)
- Output generation: Excel, Word, PDF export (a few seconds)
Lextract processes standard commercial leases in typically 5-15 minutes depending on document length and complexity.
Portfolio Scale Comparison
| Portfolio Size | Manual Abstraction | AI Abstraction (Lextract) |
|---|---|---|
| 10 leases | 40-80 hours | Under 30 minutes |
| 50 leases | 200-400 hours | Under 1 hour |
| 100 leases | 400-800 hours | 1-2 hours |
| 500 leases | 2,000-4,000 hours | 5-10 hours |
What Affects Abstraction Time
Document complexity: A simple 15-page NNN lease with no amendments abstracts faster than a 120-page full service gross lease with 8 amendments and 15 exhibits.
Scan quality: Cleanly scanned PDFs process faster and more accurately than low-resolution scans or documents with complex formatting.
Number of amendments: Each amendment must be reconciled against the base lease to determine which provisions govern. Multiple amendments significantly increase manual review time; AI tools that handle amendment hierarchies process these faster than those that require each document separately.
Field requirements: Extracting 30 fields takes less time than extracting 126. Purpose-built tools extract the full field set in a single pass.
