LeaseAbstractors reads every lease in your portfolio — office, retail, industrial, multifamily — and delivers a structured abstract with parties, premises, RSF, base rent, escalations, options and critical dates straight into your property management system in minutes, not hours.
Property management runs on leases — and every one of them is different. A single tenant file can hold a 60-page original lease, two amendments, an SNDA and a guaranty, each drafted by a different attorney. Manual abstraction means 2–4 hours per lease, transcription errors in the rent roll and renewal options discovered after the notice window closes. LeaseAbstractors eliminates all of it.
From the original lease to the latest amendment, LeaseAbstractors reads the full stack — without templates and without per-landlord training. See the full list on our document types page.
Capture tenant entity, premises and RSF, commencement and expiration, base rent and the full escalation schedule from office, retail, industrial and multifamily leases — original drafts, landlord forms and heavily negotiated redlines alike.
Changed terms tracked against the original lease, with effective dates
Fixed steps, CPI adjustments, fair-market resets, percentage rent
Expense stops, base years, caps, gross-up clauses, exclusions
Certified rent, deposits, defaults, lease modifications confirmed
Consent requirements, recapture rights, transfer premiums
Guarantor entities, deposit amounts, letters of credit, burn-downs
Renewal windows, termination options, notice periods and addresses
LeaseAbstractors slots into your tenant-onboarding workflow so your team sees a clean, validated abstract — not a PDF queue.
Leases arrive by drag-and-drop, email, API or bulk batch. LeaseAbstractors accepts digital PDFs, scans, TIFFs and photographed pages — even decades-old photocopies.
AI identifies the document — lease, amendment, estoppel, guaranty — then abstracts every key term, clause and schedule, assigning a confidence score per field.
Fields below your confidence threshold surface in a lightweight review UI, linked to the source page. Your team confirms or corrects in seconds, not hours.
Validated abstracts export to Excel, CSV or JSON, or push directly into Yardi, MRI, AppFolio or any property management platform via REST API or webhook.
Leases are messy — scanned originals, hand-initialed amendments, exhibit tables spanning page breaks. LeaseAbstractors handles all of it.

}Lease economics, tenant identities and guaranty terms are commercially sensitive. LeaseAbstractors's controls satisfy the requirements of both infosec teams and institutional owners.
DPA available for processing tenant personal data in residential and mixed-use portfolios across EU and UK assets.
Independently audited security, availability and confidentiality controls — audit report available on request.
TLS 1.2+ in transit and 256-bit AES at rest. Lease files are never stored beyond your configured retention window.
Enable automatic purge immediately after abstraction so lease documents never persist on LeaseAbstractors infrastructure.
Enterprise identity with role-based access — restrict each property manager to their own buildings and funds.
Every abstraction, review action and export is logged with timestamp and user identity for owner and auditor reporting.
"Onboarding a new management assignment used to mean three weeks of analysts re-keying leases into Yardi. LeaseAbstractors abstracted a 340-lease portfolio in two days, and the critical-date register caught four renewal windows we would have missed."
"The accuracy on scanned 1990s leases surprised us. It pulls escalation tables our manual abstracts had transcribed wrong."
"We integrated the API into our MRI instance in a week. Zero-retention mode cleared our owners' data-governance review immediately."

Ask our teamLeaseAbstractors abstracts office, retail, industrial, medical and multifamily leases, plus ground leases, NNN and gross structures. It also handles amendments, subleases, estoppel certificates, SNDAs and guaranties — with no template setup per landlord form.
Yes. The AI handles faded photocopies, skewed scans and typewriter-era originals common in legacy tenant files. Confidence scores are assigned per field so any low-confidence text surfaces for review before the abstract is pushed downstream.
LeaseAbstractors links each amendment to its parent lease and tracks which terms changed — rent, term, premises, options — so the abstract always reflects the current, as-amended position alongside the original economics.
Yes. Base years, expense stops, caps, gross-up provisions and exclusion lists are abstracted as discrete fields per lease, giving your property accountants clause-accurate inputs for the annual reconciliation instead of re-reading every lease.
LeaseAbstractors exposes a REST API and webhooks, so it connects to any platform. Pre-built export mappings exist for Yardi, MRI Software, AppFolio, Buildium and RealPage. Teams typically complete integration in under two weeks.
By default, documents and abstracted data are retained for your configured period (minimum 1 day, maximum 7 years). Zero-retention mode purges everything immediately after abstraction, leaving no tenant data on LeaseAbstractors infrastructure — ideal for GDPR and institutional-owner requirements.
