Any lease type
Trained on hundreds of thousands of real commercial leases, LeaseAbstractors abstracts every key term from virtually any lease format — typed, scanned or amended — the first time.
Base rent, escalations, RSF, TI allowances, options
Percentage rent, co-tenancy, exclusives, kick-outs
NNN terms, CAM recovery, maintenance obligations
Term, rent resets, reversion, leasehold rights
Tenants, units, rent, deposits, lease terms
Changed terms, extensions, expansions, rent updates
Certified terms, defaults, deposits, prepaid rent
Tenant, suite, RSF, rent, expirations, per unit
How it works
No more 2–4 hours of manual review per lease, no $150–$500 outsourced abstracts. Upload and the AI does the reading.
Drop in leases as PDFs or scans — a single 60-page lease or an entire portfolio. Amendments and exhibits included.
Models read every clause — rent, options, CAM, notice periods — cite the source page, and flag anything needing human review.
Download a structured abstract in Excel, CSV or JSON, or push lease data into your property management or accounting system via API.
Built for portfolios
Skip the abstraction backlog. LeaseAbstractors delivers production-ready lease abstracts with the accuracy, controls and integrations property managers, REITs and lenders require.

"We abstracted a 340-lease office and retail portfolio in under a week — work that used to take our team an entire quarter. Critical dates now land straight in our property management system."
"On an acquisition I had abstracts for 60 leases and the estoppels back the same day. My buyers see the rent roll, options and co-tenancy risks before the competition has even opened the PDFs."
"It catches the renewal options and notice windows buried on page 47 that manual abstractors miss. Our auditors loved the page citations on every ASC 842 data point."

FAQ
Upload a lease as a PDF or scan and the AI reads every clause, identifies the key terms — parties, premises & RSF, commencement and expiration, base rent and escalations, options, security deposit, CAM/OpEx recovery, insurance, assignment and critical dates — and builds a structured lease abstract you can export to Excel, CSV, JSON or pull via API.
Office, retail, industrial, ground and multifamily leases, plus lease amendments, estoppel certificates, SNDAs and rent rolls. You can also build custom abstraction templates to capture fields unique to your portfolio or playbook.
LeaseAbstractors uses AI models trained on hundreds of thousands of commercial leases, achieving high field-level accuracy even on older scanned leases. Every extracted term carries a confidence score and a page citation, and a review queue lets your team verify anything uncertain before export.
Yes. The abstract captures the data lease accounting teams need — payment schedules, escalations, renewal and termination options, commencement dates and incentives — in a structured format ready for your ASC 842 / IFRS 16 compliance workflows and auditors.
All leases are encrypted in transit and at rest, processed under SOC 2 controls, and can be automatically purged after abstraction. Your documents are never used to train models. SSO/SAML, audit logs and GDPR options are available on enterprise plans.
You can abstract your first lease free, no signup required. Paid plans are priced per lease volume and start far below the $150–$500 per lease typical of outsourced abstraction — most teams save 95% of abstraction time and cost. See the pricing page for current plans.
