To choose lease abstraction software, run a pilot on your own hardest leases: ones with amendments, scanned riders and non-standard recovery clauses. Score each tool on five things. Can you click from every field to the exact clause? Does it apply later amendments correctly? Is there a human validation record? Can it reconcile the abstract against the rent roll and CAM? Does the output land in your systems without re-keying? A tool's accuracy on a clean sample lease won't tell you much about how it handles your portfolio (v7labs.com).
It turns leases into structured data covering parties, rent schedules, critical dates, options, recoveries and key clauses. Most AI platforms follow the same steps: ingestion/OCR, parsing (body vs exhibits vs amendments), extraction, confidence scoring and structured output (v7labs.com). Some tools also reconstruct the logic behind the terms, such as commencement triggers, recovery caps and cumulative calculations, in addition to the headline fields (elysium-cre.com).
| Approach | What it is | Good fit | Watch-outs | Examples (vendor sources) |
|---|---|---|---|---|
| Managed abstract service | Experts produce the abstracts for you | Occasional large batches; no in-house team | Turnaround and cost per abstract; data isn't live | SitusAMC (situsamc.com) |
| AI + expert-validated platform | Software with vendor-side human review, often a lease admin system | Ongoing lease administration | Platform lock-in; how amendments are handled | Prophia (prophia.com), Visual Lease (visuallease.com), MRI (mrisoftware.com), Occupier (occupier.com) |
| CRE document/data engine | AI reads the whole document set and reconciles leases, amendments, rent rolls, CAM | Acquisition diligence; portfolio operations | Confirm security practices and PMS integrations | Elysium (solutions) |
| Configurable AI agent platform | You build extraction/validation agents | Teams with ops capacity to configure | "A platform to configure, not an app to open" (v7labs.com) | V7 Go (v7labs.com), Kolena (kolena.com) |
| CAM reconciliation and audit services | Firms or tools that check CAM and pass-through charges against the lease terms | A specific CAM rec or tenant-side CAM audit when you don't need a full abstract set | Scope is usually CAM and recoveries; check which documents and systems they work from | n/a |
| Pay-per-lease extractor | Upload a PDF, get fields back | Low volume, one-off leases | Extraction only, no portfolio features (kolena.com) | n/a |
| General chatbot (ChatGPT, Claude) | Paste or upload a lease and ask questions | Quick reads | Needs more careful manual handling of multi-document packages (theaiconsultingnetwork.com); no audit trail | n/a |
| Criterion | Question to ask the vendor | Why it matters |
|---|---|---|
| Source traceability | Can I click any field and see the page and clause? | An unverifiable number can't be defended to IC, lenders or auditors (v7labs.com) |
| Amendment handling | Show me a cap changed by a later amendment. | Amendments can silently overwrite a cap, e.g. non-cumulative → cumulative and compounded (NOI traps) |
| Exhibits & cross-references | Are exhibits and riders read as part of the lease? | Terms defined in exhibits are commonly missed (theaiconsultingnetwork.com) |
| Confidence & human validation | Which fields are low-confidence, and who signed off? | Lets reviewers focus where it matters; creates a record (elysium-cre.com) |
| Reconciliation | Does it compare the abstract to the rent roll and CAM ledger? | Rent roll vs lease mismatches are what single-document tools miss (v7labs.com); recovery leakage hides in caps and exclusions (OpEx post) |
| Document sources | Can it read from our Dropbox/Drive/SharePoint/Box without restructuring? | Avoids re-uploading data rooms (integrations) |
| Messy folders | Do we have to clean up and rename our folders before we start? Does the tool move or rename anything in our storage? | Cleanup is where a lot of projects stall. Elysium organizes documents inside Elysium and leaves your Google Drive, Dropbox, SharePoint, Box or Egnyte folders untouched; if you want your own folders reorganized as well, we can do that too (auto-organize post) |
| Duplicates, scans and suites | Does it catch duplicate files, read scanned PDFs, and split data by suite or subtenant? | A duplicated amendment gets counted twice, and multi-suite leases get flattened. Elysium spots duplicates, reads scanned PDFs, and where useful splits extracted data by suite and subtenant (auto-organize post) |
| Output & integrations | Excel/CSV/JSON? Yardi/MRI? | Avoids re-keying |
| Security | What are your security practices? Is our data used for training? Where is it stored? | Vendors differ; get it in writing (e.g. occupier.com, visuallease.com, solutions) |
| Custom fields | How fast can you add our firm-specific fields? | Every IC memo is different. Elysium deployed a custom extraction schema for ABJNY "inside a day" (ABJNY) |
For reading a single lease, often yes. For a portfolio or an acquisition, the gap is audit trail and multi-document logic. General tools need careful manual management of multi-document lease packages (theaiconsultingnetwork.com). Our view is that high-stakes CRE work needs a structured, click-to-source paper trail, which a chat window doesn't give you (updates.elysium-cre.com).
Public pricing is rare, and most platforms quote on request. Elysium's pricing is consumption-based, priced per document.
On time saved, the ROI calculator on our solutions page uses industry benchmarks of ~4 hours per manual document abstraction at $95/hour fully loaded, with an 85% time reduction observed across Elysium deployments. The calculator labels its estimates as illustrative (solutions).
How accurate is AI lease abstraction?
It depends on the lease. Test on your non-standard leases. Accuracy drops on non-standard clauses, complex escalations and cross-referenced exhibits (theaiconsultingnetwork.com).
Do I still need human review?
Yes, for material terms. Look for tools that record who validated each field and when (elysium-cre.com).
What documents should be abstracted besides leases?
Amendments, estoppels, rent rolls, and in diligence also loan documents and vendor/partnership agreements (elysium-cre.com).
How long does implementation take?
Tools that read from existing cloud folders can start without migrating data (integrations). ABJNY had a custom extraction schema deployed "inside a day" (ABJNY).
Do I need to clean up our document folders first?
Not with Elysium. You can bring folders in as they are, and Elysium organizes them inside Elysium and queues them for extraction. Your originals keep the same names and folders. If you'd like your own folders reorganized too, we can do that as well (auto-organize post).
What's the difference between lease abstraction and lease administration?
Abstraction produces the structured data. Administration manages it over time: critical dates, obligations, reporting. Some vendors do both, e.g. Prophia (prophia.com) and Visual Lease (visuallease.com).
