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.
The number of days allowed to remedy operational or physical breaches after notice.
Also known as: Performance Grace Period

Non-monetary defaults (like failing to maintain insurance, unauthorized alterations, or use violations) are often more complex to cure than simply writing a check. A 10-day cure period for obtaining new insurance coverage may be insufficient if the tenant needs to switch carriers. Standard non-monetary cure periods of 30 days with the ability to extend for good-faith efforts protect the tenant from losing the lease over administrative delays.
In the "Default" section, usually in a separate paragraph from the monetary cure period. Look for "non-monetary default" or "other defaults." Well-drafted leases include a "diligent pursuit" extension if the cure cannot reasonably be completed within the initial period.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the non-monetary cure from your lease PDF. The AI searches for the field name and common aliases like "Performance Grace Period" across 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.
Monetary Cure Period
The number of days allowed to remedy missed financial payments after notice.
Acceleration Clause
Landlord's right to demand all future rent immediately upon a lease default.
Liquidated Damages
A predetermined penalty fee assessed for specific breaches of the contract.
Late Fee %
The penalty percentage applied to overdue rent payments.
Holdover Rate
The multiplier applied to base rent if the tenant remains post-expiration.
Most leases allow 30 days to cure non-monetary defaults, with an extension if the tenant is diligently pursuing the cure and it reasonably cannot be completed in 30 days. Periods shorter than 20 days are unusual and should be flagged.
Common non-monetary defaults include: failure to maintain required insurance, unauthorized alterations, violation of permitted use restrictions, failure to comply with rules and regulations, abandonment of the premises, and failure to deliver an estoppel certificate within the required timeframe.
