Extract data from lease agreements

Lease agreements are the operating record of real estate portfolios, and they almost never live in a single, queryable place. A national property manager might hold 4,000 active leases across 38 states, in formats that range from a one-page residential template generated out of AppFolio, to a 47-page commercial triple-net lease drafted by counsel for a flagship retail tenant, to a sublease addendum that modifies the master lease in ways that only become relevant during a Section 365 bankruptcy filing. Leasing operations teams need to know, on demand: what's the monthly rent on Unit 4B at 1200 Market Street, when does the term expire, is there an auto-renewal, what is the security deposit, who signed on behalf of the tenant entity, and which state's law governs the agreement. Asking a paralegal to find that across 4,000 PDFs is how renewal deadlines get missed. The hard parts are clauses, not metadata. Term descriptions read like "thirty-six (36) months commencing on the Commencement Date, with two (2) successive options to renew for additional periods of twelve (12) months each, exercisable by Tenant by written notice to Landlord no less than 90 days prior to the expiration of the then-current Term." That structure has to come out as: term length 36 months, renewal options 2 × 12 months, notice 90 days. Rent escalation schedules are often tables embedded mid-document. A Triple Net Lease for retail space at 1200 Market Street in San Francisco might escalate base rent 3% annually starting 2026-06-01, with operating-expense pass-throughs for Common Area Maintenance and a $1,200,000 Tenant Improvement Allowance amortized over the initial term. Operating expense pass-throughs in commercial leases reference exhibits that may or may not be attached. Personal guarantees by individual principals sit alongside corporate signatures. Governing law clauses can name one state (Delaware, New York, California) for general terms and a different one (often New York) for arbitration venue. Talonic extracts the structured contract metadata while preserving the clause text verbatim. Parties are parsed with role tags (landlord, tenant, guarantor). The term is captured as a plain-language description and a structured term length where the document is unambiguous. Rent, security deposit, and renewal options surface as discrete fields when the lease states them cleanly; complex pass-through and escalation language is kept as a clause excerpt so legal can review the source rather than trust a parsed approximation.

What gets extracted from lease agreements

How extraction works for lease agreements

Lease agreements vary across residential, commercial, ground, and equipment lease categories, so a single template-based extractor breaks immediately. Talonic classifies the lease and runs it through the contract schema in the Field Registry, which captures parties, term, governing law, indemnity, and termination structure without requiring per-template configuration. Defined Terms (capitalized words like "Tenant" or "Premises") are resolved in context so that extracted values reflect the contract's intended meaning rather than surface text. Personal guarantees are tagged as additional parties with a guarantor role. Every extracted clause is anchored to its position in the source PDF, with pixel-region provenance for audit review under DIN SPEC 91491 conformity, so counsel can verify any captured term against the original document before relying on it for renewal or compliance reporting.
