Why NuSource Lease Abstraction

Institutional real estate cannot fully depend on AI-only abstraction.

NuSource Lease Abstraction is AI + humans. Every output passes through a real estate specialist before it reaches your system. NEx4 does the heavy lifting; experienced practitioners are the checkpoint institutional clients require.

Pure AI Abstraction Tools
Fast, but unaccountable.
  • Generic LLM with a real estate prompt layered on top
  • No human checkpoint before delivery
  • Confidence scores you can’t audit
  • Hallucinated data on complex clauses
  • Crowdsourced contractors as fallback
NuSource Lease Abstraction
Fast, and accountable.
  • Custom-trained LLM (NEx4) on real estate leases
  • Human review on every single output
  • Per-field confidence scoring with full audit
  • Edge cases escalated to senior specialists
  • Salaried in-house team — never outsourced QA
What you get

Abstract once, use it in every department and every system.

Each output is delivered into your system in your schema, with full audit trail and per-field confidence scoring. No reconciliation needed downstream.

Core Output

400+ data points, every clause

From the obvious (rent, term, renewal options) to the complex (co-tenancy, exclusives, indemnity caps, percentage rent, CAM caps). Every clause type extracted with per-field confidence.

Quality Output

Human-reviewed before delivery

The largest specialized real estate QA team in the industry checks every output. AI proposes; humans confirm. Edge cases escalate to senior specialists. Nothing reaches your team unchecked.

Critical Dates

Tracked & flagged

Renewal options, termination rights, rent reviews, notice periods — flagged with calendar exports so nothing is missed.

Easy Reporting

Report builder, plus Ask Me+

An intuitive report builder for quick reports — plus the “Ask Me+” feature to ask in any language, in a conversational style.

Audit Trail

Full chain of custody

Every annotation, every reviewer, every change captured for SOC 2 and audit defensibility.

Delivery

Straight into your stack

Pushed to Yardi, MRI, JD Edwards, Argus, and Oracle via open APIs — or Excel, CSV, and JSON for ad-hoc delivery. No manual handoff.

Questions

Frequently asked.

What is NuSource Lease Abstraction?
A co-sourced lease abstraction service. NTrust's NEx4 AI engine reads the lease and extracts 400+ data points across 83 provisions. Every output is then validated by a Real Estate-trained specialist before delivery to your system. Standard turnaround under 4 hours per lease at ~99% final accuracy.
Why human validation if NEx4 is so accurate?
For institutional Real Estate, the difference between 92% and 99% is the difference between operational risk and operational confidence. Edge cases — complex co-tenancy, unusual indemnity structures, custom escalations — are where AI struggles. Humans aren't a backup; they're a checkpoint that institutional clients require.
What languages do you support?
26+ languages with native processing — including English, Spanish, French, German, Italian, Portuguese, Dutch, Mandarin, Japanese, Korean, Arabic, and others. Reviewers speak the source language; abstraction is delivered in your target language.
What lease types do you handle?
Office, retail, industrial, mixed-use, hospitality, ground leases, sub-leases, intercompany leases. Multi-document leases (lease + amendments + exhibits + side letters) are auto-grouped and processed as a single unit.
How does it integrate with our system?
Direct integration with Yardi (Voyager, Elevate), MRI (Platform X, Horizon), JD Edwards, Argus, Oracle ERP, SAP via open APIs. Excel, CSV, JSON, XML for ad-hoc delivery. Web service hooks for real-time integration.
What's the typical turnaround?
Standard commercial leases: under 4 hours from submission to delivered abstract. Multi-document leases: under 6 hours. Bulk migration projects: typically 100–500 leases per day across the team. Rush turnaround available for transactions.
How do you handle security?
SOC 2 Type 2 certified. GDPR-compliant processing. Segregated client environments. MFA required for all users. Full audit trails. Data residency configurable per client. References available on request.
