Charleston County office lease: estimated payment true-up case study
A public-record government office case study where the pipeline surfaced a gross-up advisory on a $412,837 expense pool. The Rule 18 true-up finding from the prior pipeline run did not reproduce in the current multi-pass extraction.
What happened
Charleston County leased 5,000 square feet at 4000 Faber Place Drive under a triple-net lease with a 10% pro-rata share. Monthly CAM estimates of $3,000 added up to $36,000 paid during the year. When the 2024 reconciliation arrived, the landlord billed a $8,500 true-up. The math from the building expense ledger suggests the correct true-up is $5,283.76. The current multi-pass extraction pipeline did not extract sufficient true-up data to fire Rule 18, so only a gross-up advisory was produced.
Findings from the pipeline
Lease evidence
- Pro-rata share fixed at 10.00% (5,000 SF / 50,000 SF).
- Triple-net structure with annual CAM reconciliation.
- Monthly estimates of $3,000 collected during the year.
- True-up methodology: actual tenant share minus cumulative estimates paid.
Why this matters
Year-end true-up errors are easy to miss because tenants rarely see the building expense ledger. The landlord presents a single line showing what you owe, and most tenants pay it. The fix is straightforward: multiply total building expenses by your pro-rata share, subtract what you already paid in estimates, and compare. This case demonstrates that extraction quality directly affects detection coverage.
