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.

  • +CAMAudit: $79 flat fee, results in under 15 minutes, 14 forensic detection rules.
  • -CoStar: $thousands/month per module (multi-year contract), not applicable (market data platform, not an audit tool), none (market intelligence, not tenant cam auditing).
  • iCoStar is built to track leases, compliance, or portfolio operations. CAMAudit is built to detect CAM billing errors against the actual reconciliation and surface overcharge dollars the tenant can act on.

CoStar

Not applicable

CoStar is a market intelligence platform; it does not perform CAM audits

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 CoStar if

  • •You need lease accounting, compliance, or portfolio administration across many leases.
  • •You have the budget and internal team for enterprise software implementation.

Overcharge detection

CoStar is built to track leases, compliance, or portfolio operations. CAMAudit is built to detect CAM billing errors against the actual reconciliation and surface overcharge dollars the tenant can act on.

ROI and fee drag

CoStar typically brings subscription pricing, implementation effort, and internal admin overhead. CAMAudit wins on ROI for audit use cases because the tenant pays a flat fee only when they want to unlock findings.

Implementation burden

CoStar usually needs onboarding, workflow setup, or internal ownership. CAMAudit is faster to value because it behaves like an audit workflow, not a system implementation.

Why tenants choose CAMAudit

  • ✓CAMAudit costs $79/audit; CoStar costs thousands per month
  • ✓Purpose-built for tenant protection vs. market intelligence
  • ✓No data-sharing or lock-in
  • ✓Forensic findings in minutes without a data subscription

CoStar strengths

  • •Integrated lease accounting
  • •Comprehensive comp database
  • •Industry standard

CoStar limitations

  • •Closed ecosystem
  • •No CAM overcharge detection
  • •Requires multi-year contracts

CoStar key features

  • •Lease accounting engine
  • •Comp database
  • •Portfolio analytics

Notable absences in CoStar

  • ✗Closed ecosystem limits external audit use
  • ✗Monopolistic pricing
