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.
The number of days allowed to remedy missed financial payments after notice.
By Angel Campa, Founder · Updated March 2026
A short monetary cure period (3-5 days) gives the tenant almost no time to resolve a missed payment before the landlord can declare default and pursue remedies including eviction. Most bank wire transfers take 1-3 business days to process. A cure period of 5 business days (not calendar days) is the minimum reasonable standard. Missing this field during abstraction means the accounting team cannot properly prioritize payment deadlines.
Found in the "Default" or "Events of Default" section. Look for language about "failure to pay rent within X days after written notice" or "monetary default." The cure period for monetary defaults is usually shorter than for non-monetary defaults.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the monetary cure period 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.
Lextract automatically checks this field against its 15-rule red flag engine. Issues detected for monetary cure period:
Non-Monetary Cure
The number of days allowed to remedy operational or physical breaches 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 commercial leases allow 5 to 10 days to cure a monetary default after written notice from the landlord. Some tenant-friendly leases provide 15-30 days. Periods shorter than 5 days are aggressive and should be flagged during abstraction.
This varies by lease. "Upon receipt of written notice" starts the clock when the tenant actually receives it. "Upon delivery" may start when the landlord mails or sends the notice. The method of notice delivery (email, certified mail, overnight courier) affects the effective start date.
