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.
Indicates a ROFO to lease space before it hits the open market.
By Angel Campa, Founder · Updated March 2026
A ROFO requires the landlord to offer available space to the tenant before marketing it publicly, giving the tenant first-mover advantage on expansion opportunities. Unlike a ROFR, the terms are proposed by the landlord rather than dictated by a third party, giving the tenant more negotiating room. However, if the tenant declines, the landlord can lease to anyone -- making the initial evaluation critical.
Found in the "Options" or "Expansion Rights" section. Look for language about the landlord's obligation to "first offer" space to the tenant before marketing. The response period, eligible spaces, and reactivation triggers should be specified.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the right of first offer from your lease PDF. The AI searches for all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty. Fields with lower confidence are flagged for human review.
Has Renewal Option
Indicates the presence of a contractual right to extend the lease term.
Renewal Terms
The specific parameters of the renewal.
Renewal Notice (Days)
The deadline prior to expiration by which the tenant must exercise the renewal.
Has Termination Option
Indicates the right to break the lease prior to the natural expiration date.
Termination Penalty
The fee or liquidated damages required to execute an early termination.
Right of First Refusal
Indicates a ROFR on specific adjacent or building spaces.
A ROFO is triggered when the landlord becomes aware that covered space will become available, typically upon receiving notice of an existing tenant's non-renewal or early termination. The landlord must then offer the space to the ROFO holder before marketing it to outside parties.
Well-drafted ROFOs include a "reactivation" clause: if the landlord offers the space to a third party at terms materially more favorable (e.g., 10% less rent) than what was offered to the tenant, the ROFO rights reactivate and the tenant gets another chance.
