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 legal corporate entity leasing the premises.
Also known as: Lessee, Occupant

The tenant entity on the lease determines financial liability, creditworthiness evaluation, and whether a personal guarantee is necessary. If a franchise operator signs under a different LLC than expected, the landlord may have limited recourse against the broader organization in the event of default.
Found in the lease preamble on page one, typically alongside the landlord name. Also confirmed in the signature block and any guaranty exhibit.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the tenant name from your lease PDF. The AI searches for the field name and common aliases like "Lessee", "Occupant" 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.
Landlord Name
The legal corporate name of the landlord/lessor.
Guarantor Name
The entity or individual providing financial backing for the tenant.
Premises Address
The full physical address of the leased space.
Suite/Unit Number
The specific identifier for the tenant's space within a multi-tenant building.
Rentable Area (RSF)
The total area for which the tenant pays rent, including common area allocations.
Usable Area (USF)
The exact private physical space occupied by the tenant.
Not necessarily. The lease should list the legal entity (e.g., "ABC Holdings LLC"), which may differ from the trade name ("ABC Coffee"). The permitted use clause typically specifies what trade names can be used at the premises.
Changing the tenant entity usually requires landlord consent and may trigger assignment provisions. A simple name change (same entity, new name) is typically permitted with written notice, but converting from an LLC to a corporation may constitute an assignment.
