CAM and NNN billing
Separate what was billed from what needs proof.
CAM and NNN charges may be permitted under your lease. An overcharge question arises only when a specific billed item, allocation, or calculation does not match the agreement or supporting records.

Caps and fees
Identify exactly which costs are limited and how administrative fees are calculated.
The signed lease, annual statement, and available records determine what can be verified.
A practical review
Four common sources of review questions.
Start with the particular line and the rule that may apply to it. A large total by itself is not evidence of an error.

An illustrative example
$70,000 billed is not $70,000 recoverable.
If a 10,000-square-foot tenant is billed $7 per square foot in annual CAM and NNN, the arithmetic totals $70,000. That is the annual charge, not the amount of any possible overcharge.
Illustrative arithmetic only. Do not treat the bill total or a guessed percentage as verified savings.

What the documents can tell you.
Are all CAM and NNN charges overcharges?
No. The signed lease may permit many of them. The task is to verify the particular billed cost and calculation.
Can I estimate recovery as a fixed percentage of my bill?
No. A percentage without document support is not a reliable recoverable amount.
Does a flagged item prove an overcharge?
No. It is a question to verify against the signed lease, the annual statement, and supporting records. A charge can be valid even when it warrants review.
Is there a standard audit deadline?
No. Read the signed lease and amendments for the trigger, period, required action, recipient, and delivery method. Different review steps may have different rules.
