Why This Matters Financially
Even small CAM allocation errors can cost tenants $5,000–$50,000+ annually. Because CAM and NNN charges recur every year, unnoticed errors compound over time.
Reviewing your lease before audit windows close preserves leverage, protects your ability to dispute overcharges, and helps prevent avoidable costs from becoming permanent.
