Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Desktop CAM Audit vs Full Forensic Audit

Last updated: April 2026

By Angel Campa, Founder

Desktop audits review the reconciliation as-is. Forensic audits dig into the landlord's books. Start with a desktop audit and escalate if overcharges are found.

Desktop CAM Audit

A desktop audit reviews the reconciliation statement and lease documents without requesting access to the landlord's underlying books and records. The auditor analyzes the numbers as presented, checking for mathematical errors, lease compliance, and obvious anomalies from the documents the tenant already has.

Advantages

  • ✓Fast turnaround, often completed in hours rather than weeks
  • ✓Does not require landlord cooperation or records access
  • ✓Lower cost than a full forensic audit

Disadvantages

  • ✗Cannot verify whether the expense amounts reported by the landlord are accurate
  • ✗Misses overcharges hidden in supporting documentation
  • ✗Limited to what can be detected from the reconciliation statement itself

Full Forensic Audit

A full forensic audit examines the landlord's original invoices, contracts, general ledger entries, and supporting documentation behind every line item on the reconciliation. The auditor traces each expense from vendor invoice to tenant bill, verifying accuracy, lease compliance, and proper allocation.

Advantages

  • ✓Catches overcharges hidden in vendor invoices and internal allocations
  • ✓Provides the strongest evidence for dispute letters and recovery negotiations
  • ✓Comprehensive verification of every dollar charged

Disadvantages

  • ✗Requires exercising formal audit rights and landlord cooperation
  • ✗Time-consuming, often taking weeks to months for complex properties
  • ✗Expensive, especially when using traditional CPA firms

How This Affects Your CAM Charges

Desktop audits serve as an effective first pass to identify the most common and obvious overcharges. They catch math errors, pro-rata share mistakes, cap violations, and charges that clearly violate lease exclusions. Full forensic audits go deeper, catching vendor markup, internal cost allocation errors, and charges supported by inflated or fabricated invoices.

Which Exposes You to More Risk?

Neither is inherently worse for the tenant. Desktop audits miss things a forensic audit would catch, but they cost far less and require no landlord cooperation. The optimal strategy is to start with a desktop audit, and if it finds significant issues, escalate to a full forensic review using your lease's audit rights.
