Free Lease Abstract Discrepancy Matrix

Track CAM caps, expense stops, and admin fee carve-outs across your portfolio.

A lease abstract matrix tracks the key CAM terms across every lease: caps, escalators, expense stops, admin fee carve-outs, and exclusion categories. Without one, property controllers rely on memory or scattered notes. That leads to missed caps and billing errors.

What's inside

One row per tenant: NNN, gross, and modified gross structures
Auto-flags missing CAM caps, stale reconciliations (12+ months), and inconsistent data
Works for inherited portfolios with no existing lease abstracts
Excel-based and formula-driven. No proprietary software needed.

Built for inherited portfolios. Works even if you don't have existing lease abstracts - just enter what you know and let the flags guide you.

Frequently Asked Questions

What is a lease abstract matrix?

A lease abstract matrix is a spreadsheet that pulls and organizes the key financial terms from every lease in a property. For CAM reconciliation, it tracks caps, expense stops, admin fees, base year amounts, pro-rata shares, and excluded expense categories across all tenants.

Why do missing lease abstracts cause CAM errors?

Without a central abstract, controllers must re-read each lease for every reconciliation cycle. This leads to missed cap escalators, forgotten exclusion clauses, wrong base year amounts, and admin fee errors. All of these are common sources of CAM billing mistakes.

What CAM terms should a lease abstract track?

At minimum: tenant name, suite, leased SF, pro-rata share, lease start and end, CAM cap (fixed or CPI), cap escalator percentage, expense stop amount, base year, admin fee percentage, excluded expense categories, and any special terms like anchor exclusions or gross-up thresholds.

How often should lease abstracts be updated?

Review and update abstracts at every lease execution, renewal, amendment, and expansion. Many portfolios also do an annual check of all abstracts before reconciliation season to catch stale data, especially cap escalators that grow each year.

This free tool only gives a rough guess. The numbers may be wrong. Check your own lease and records first. This is not legal or tax advice.
