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.

High risk of missing overcharge types without forensic methodology; no dispute letter output

Choose CAMAudit if

  • ✓You need to find CAM overcharges, not just organize lease data.
  • ✓You want quantified findings and the best recovery economics from a flat-fee audit.

Choose DIY CAM Audit if

  • •You only want a rough estimate or quick self-serve check and are willing to do the analysis yourself.

Overcharge detection

DIY CAM Audit can help with rough calculations, but it does not perform a forensic lease-versus-reconciliation audit. CAMAudit wins because it runs the full 14-rule audit on the actual documents.

ROI and fee drag

DIY CAM Audit looks cheaper upfront, but the hidden cost is missed errors and manual time. CAMAudit usually produces better ROI because it gives the tenant a higher-confidence path to recover real dollars.

Implementation burden

DIY CAM Audit shifts the work onto the tenant through manual entry and interpretation. CAMAudit reduces that burden by extracting the lease and reconciliation automatically.

  • ✓Results in under 15 minutes vs. days or weeks of manual spreadsheet work
