What is CAM reconciliation?

Common Area Maintenance charges are estimated monthly but reconciled annually against actual property operating expenses. The system calculates each tenant's share, issues credit or charge invoices, and tracks the reconciliation workflow.

How does the critical date calendar work?

All date-sensitive lease events (option exercise deadlines, rent bumps, expiry dates, notice periods) are entered as critical dates. The system sends configurable advance warnings to the asset manager and leasing team.

Weighted Average Lease Term is the average number of years remaining across all leases, weighted by square footage. It's a key investor metric showing the portfolio's income stability risk.

The Challenge

Why building a Lease Management from scratch is hard

Building a Commercial Lease Management System from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing lease management-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Lease Management needs

ProjectCode generates a production-ready Lease Management with all the modules your team needs from day one.

Lease abstraction with key terms and critical date extraction

Lease calendar with rent escalation and option tracking

CAM (Common Area Maintenance) reconciliation

Tenant estoppel certificate management

Lease renewal and expansion negotiation workflow

Rent invoice generation and payment tracking

Operating expense auditing tools

Portfolio analytics: occupancy, WALT, lease expiry ladder

Architecture

How it's built

The generated Lease Management follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for lease management workflows

NestJS REST API with dedicated lease management modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all lease management entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live lease management status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Lease Management

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

leases (id, property_id, tenant_id, unit_id, type, start_date, end_date, base_rent, escalation_rate, cam_rate, deposit, options jsonb, signed_at)
rent_schedules (id, lease_id, period, base_rent, cam_charge, total, status, invoice_id, paid_at)
cam_reconciliations (id, lease_id, year, estimated_cam, actual_cam, variance, credit_or_charge, status)
critical_dates (id, lease_id, type, date, description, notice_required_days, alert_sent, owner_id)

FAQ

Common questions about building a Lease Management

Lease abstraction is the process of extracting key terms from the full lease document (rent, escalations, options, notice requirements, restrictions) into structured data. The generated system includes an abstraction form and supports importing from legal databases.
