Lease abstraction for property management.
Every term. Every date.

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.

Field-level accuracy on key terms

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.

Document coverage

Every document in the tenant file

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.

Abstraction workflow

From signed lease to structured abstract in four steps

LeaseAbstractors slots into your tenant-onboarding workflow so your team sees a clean, validated abstract, not a PDF queue.

01

Upload

Leases arrive by drag-and-drop, email, API or bulk batch. LeaseAbstractors accepts digital PDFs, scans, TIFFs and photographed pages, even decades-old photocopies.

02

Abstract & classify

AI identifies the document, lease, amendment, estoppel, guaranty, then abstracts every key term, clause and schedule, recording the source page for each field.

03

Review

The abstract opens next to the source document with the page number for each field, so your team confirms or corrects in seconds, not hours.

04

Push to your system

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.

Purpose-built for property management

Capabilities that match how portfolios actually run

Leases are messy, scanned originals, hand-initialed amendments, exhibit tables spanning page breaks. LeaseAbstractors handles all of it.

Critical-date tracking
Renewal exercise windows, termination options, co-tenancy triggers and notice deadlines extracted with the exact notice period and delivery address, feed them to your calendar or PM system before a date ever slips.
Escalation schedule tables
Fixed steps, CPI formulas and fair-market resets captured row by row as a structured rent schedule, ready to drop into your rent roll without retyping a single period.
CAM reconciliation prep
Base years, expense stops, caps, gross-up provisions and exclusion lists abstracted per lease, so annual CAM reconciliations start from clause-accurate data instead of tribal knowledge.
Rent roll accuracy audits
Run your existing rent roll against the abstracted leases to surface mismatched rents, missing escalations and expired terms across the whole portfolio.
PM system integration
Structured output mapped for Yardi, MRI Software, AppFolio, Buildium and any REST-capable platform. Data lands where your property accountants work, not in a silo.

FAQ

Lease abstraction questions from property managers

Have a question not covered here? Our team has answered hundreds of property-management-specific use cases.

Ask our team

Which lease types does LeaseAbstractors support?

LeaseAbstractors 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.

Can it read old scanned leases?

Yes. Scanned and photographed pages are read with OCR, including faded photocopies and typewriter-era originals common in legacy tenant files. Quality varies with the scan, so every field records the page it came from and the abstract opens next to the document for review before it is pushed downstream.

How does it handle amendments to the original lease?

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.

Can it prepare data for CAM reconciliation?

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.

Which property management systems can it integrate with?

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.

Is tenant data stored after abstraction?

Documents and abstracted data are retained for the period you configure (minimum 1 day, maximum 7 years). You can delete them from the workspace at any time, and we will remove everything on request.
