AI Lease Abstraction Accuracy: Benchmarks and What to Expect
What accuracy can you realistically expect from AI lease abstraction tools? We break down field-level accuracy rates, where AI excels, where it struggles, and how to validate output.

Many portfolios operate with paper or scanned leases that have never been digitized into structured data. Building an accurate lease database from scratch requires abstracting every document — a project that takes months manually and is cost-prohibitive with traditional abstraction services.
Scan paper leases to PDF using a multifunction printer or a document scanning service. Ensure resolution is at least 300 DPI for accurate OCR.
Upload all scanned lease PDFs. Lextract uses AWS Textract for OCR, which handles scanned documents including handwritten amendments.
Lextract processes each document and generates a complete structured abstract with confidence scores for every field.
Work through flagged fields for each lease, cross-referencing the original scanned document to confirm values.
Export all abstracts into a consolidated Excel database. This becomes the portfolio's master lease record — the single source of truth for all lease terms.
Learn about the full integration between Lextract and Microsoft Excel, including supported export formats and critical fields.

At $20 per lease, digitizing a 100-lease portfolio costs $2,000 with Lextract. Traditional lease abstraction services typically charge $150–$400 per lease for the same scope.
