AI lease abstraction for owners, occupiers and finance teams. It reads the lease and every amendment, rebuilds the current rent schedule and options, and cites the page for each field. Your lease administrators and accountants approve before anything posts.
AI lease abstraction is the use of document AI and language models to read commercial leases, amendments and side letters and extract the key terms into a structured record. It outputs parties, premises, term, rent and escalation schedules, renewal, break and purchase options, service charge or CAM terms and critical dates, each linked to its source clause, ready for lease administration and IFRS 16 or ASC 842 calculations.
Portfolios grow through acquisitions, renewals and amendments. Abstracts go stale, critical dates live in spreadsheets, and lease accounting depends on data nobody has re-checked against the documents.

We group each lease with its amendments, licences and side letters, then extract terms using your abstract template.
The system works out which clause is current when amendments overlap, and flags conflicts instead of guessing.
Approved abstracts flow into the systems that run your portfolio and your lease accounting.
We agree your abstract template and pick 50–100 leases across property types and regions, including some with heavy amendment history. One metric is set: field accuracy or hours per abstract.
Your team or existing abstracts provide a verified answer key for 20 leases. We measure field-level accuracy and fix extraction rules where it misses.
Lease administrators review AI abstracts side by side with the source pages, correcting fields in one click. Corrections are tracked.
Approved abstracts load into your lease system and critical-date alerts switch on. We report accuracy, reviewer time per lease and the rollout plan.
| Criterion | Manual or outsourced abstraction | Lease software with built-in AI | Stratgik build + run |
|---|---|---|---|
| Turnaround for a backlog | Weeks to months | Fast for standard leases | Days, with reviewer queue sized to your team |
| Amendments and side letters | Depends on the abstractor | Often abstracted document by document | Reconciled into one current position with conflicts flagged |
| Evidence for auditors | Abstract only | Varies; some link to pages | Clause and page citation on every field |
| Custom fields and jurisdictions | Flexible but slow | Template-bound | Your template, UK, US and UAE lease conventions |
| Systems | Manual re-keying | Best inside that vendor's platform | Writes to Yardi, MRI, Visual Lease, NetSuite or your ERP |
| Best fit | Occasional small batches | Single-platform portfolios with standard leases | Acquisitions, mixed portfolios, lease accounting clean-up |
Since IFRS 16 and ASC 842, a wrong commencement date or missed option changes reported liabilities, not just a property file. Accurate, cited abstracts are the input everything else depends on.
Two sources of value: reviewer hours saved and rent or recovery errors caught when abstracts match the documents. The time saved and error rate are assumptions; the pilot measures both on your leases.

Up to 100 leases, one abstract template, one lease system
Ongoing abstraction of new leases and amendments
Backlogs, acquisitions and lease accounting integration
OCR pages, model usage and cloud hosting billed at cost. Stratgik does not provide accounting or legal advice; lease classification, discount rates and option assessments are decided by your accountants and auditors. Taxes excluded. GBP and AED prices are indicative conversions from USD.
AI lease abstraction is typically most accurate on explicit terms such as dates, rent amounts and parties, and needs more review on judgement-heavy clauses like options conditions or service charge caps. Accuracy varies with scan quality and drafting, so our pilot measures it field by field against a verified set of your own leases. Every field carries a page citation so reviewers can check quickly.
Yes. The system groups each lease with its deeds of variation, amendments, licences and side letters, orders them by date, and rebuilds the current position for each term. Where two documents conflict or the drafting is ambiguous, it flags the conflict with both citations for a lease administrator to decide rather than picking one.
It prepares the inputs, not the accounting judgements. The abstract provides commencement date, term, payment schedule, escalations, incentives and options, and flags items your accountants must assess, such as whether an option is reasonably certain. Those inputs feed your lease accounting tool or ERP, where your team applies discount rates and classification.
Stratgik's pilot is a fixed $12,000 for up to 100 leases using one template and one target system. Run is $2,500 a month for ongoing new leases and amendments. Scale for backlogs, acquisitions and accounting integration starts from $6,000 a month. OCR and model usage are billed at cost. Per lease, this usually compares favourably with outsourced abstraction at volume.
Yes. We configure templates for regional conventions: UK rent reviews, break clauses and service charge; US CAM, operating expense reconciliations and co-tenancy; and UAE lease terms including Ejari registration details and service charge provisions. Arabic-language or bilingual leases are supported, with extraction quality tested during the pilot.
A backlog of several hundred leases can usually be drafted within days once the template is agreed; the pace is set by how quickly your reviewers approve abstracts. In the 21-day pilot we complete up to 100 leases and measure reviewer time per lease, which gives a reliable forecast for the remaining portfolio.
The ones with years of amendments. We will return cited abstracts and a list of conflicts found, so you can judge accuracy on your own documents.
