How to Use the NNN Lease CAM Reconciliation Reviewer Prompt to Catch Overcharges Before the Audit Window Closes

Every year, tenants in triple net leases receive a reconciliation statement for common area maintenance, taxes, and insurance. Many pay the balance without checking it against the lease. The most common errors are a pro rata share built on the wrong denominator, capital projects charged in full, and caps that were never applied. The Commercial NNN Lease Abstract and CAM Reconciliation Reviewer: Pro Rata Share Denominator, Expense Exclusions, Controllable CAM Cap, Admin Fee Limits, Audit Deadline, and a Tenant Dispute Letter prompt abstracts the clauses that control your bill, recomputes the statement line by line, and drafts a dispute letter before your audit deadline passes.

What the prompt produces

1. A lease abstract limited to the operating expense clauses, with section numbers and a plain reading.
2. A pro rata share check comparing the lease's percentage to the one on the statement.
3. An expense review marking each line allowed, excluded, or needing backup, with amortization for allowed capital items.
4. Cap math that splits controllable from uncontrollable expenses and applies the cap the way the lease defines it.
5. An admin fee recalculation on the base and rate the lease allows.
6. A corrected reconciliation set beside the landlord's numbers, showing the true balance or credit.
7. An audit deadline computed from the date you received the statement.
8. A dispute letter citing lease sections, corrected numbers, and the documents you want to see.

How to fill the inputs

LeaseExcerpts should quote the actual clauses: operating expense definitions, exclusions, the pro rata share formula, caps, admin fees, gross up, and audit rights. The prompt only uses what you paste.

PremisesAndBuildingArea gives your square footage and the building or center area as the lease defines it.

ReconciliationStatement is the landlord's statement line by line, including the share percentage they used.

EstimatesPaid is what you paid in monthly estimates during the year.

PriorYearBase is last year's controllable expense total, needed if your lease caps increases.

StatementDates records when you received the statement and which year it covers.

Reading the example output

The example reviews a 2,400 square foot retail space in a 48,000 square foot center:

• The denominator is wrong. The lease says leasable area whether or not leased, but the landlord used occupied area, raising the share from 5 percent to 6 percent.
• A parking lot repaving project was charged in full. The lease only allows the annual amortized cost, so the prompt shows the amortization and flags the useful life as an assumption to confirm.
• Leasing commissions are removed because the lease excludes them.
• The controllable cap is applied at 5 percent over the prior year, with snow removal left outside the cap as the lease says.
• The admin fee drops from 15 percent on the whole pool to 10 percent of CAM only.
• The corrected numbers turn a balance due into a credit, with every calculation shown.
• The audit deadline is calculated, and the letter reserves audit rights.

Tips for better results

• Paste the full exclusions list. Short excerpts miss the clause that matters.
• Ask the landlord for last year's reconciliation if you do not have the prior year base.
• Request the general ledger and invoices for large items before agreeing to anything.
• Calendar the audit deadline the day the statement arrives.
• Have counsel review any clause the prompt marks as needing counsel.

Mistakes to avoid

• Do not withhold rent while a reconciliation is in dispute unless your attorney advises it.
• Do not assume a cap or gross up exists if it is not in the lease.
• Do not miss the audit window. Many leases treat the statement as final afterward.
• Do not accept a share percentage without checking the denominator.
