Are these tools really free?
Yes — all four tools are completely free with no email required. You get the full results instantly. If you want a forensic audit of your actual reconciliation statements, that requires a paid credit.
How accurate is the CAM Overcharge Estimator?
The estimator uses industry benchmark overcharge rates per lease type — it gives you a plausible range based on what tenants in similar situations typically recover. For an exact number, you need CamAudit to run against your actual documents.
What is gross-up and why does it matter?
Gross-up provisions allow landlords to normalize operating expenses to a hypothetically fully-occupied building. When applied incorrectly — at the wrong threshold, to the wrong expense categories, or using the wrong base occupancy — tenants can pay thousands more than they should.
Should I get a CAM audit even if my landlord seems honest?
Billing errors are common even when landlords are acting in good faith. Complex lease terms, multiple tenants, and year-over-year reconciliations all create opportunities for errors. Many tenants recover money without any dispute at all — their landlord simply corrects the statement.
How is CamAudit different from these free tools?
The free tools give you estimates and red flags based on inputs you enter. CamAudit processes your actual lease and reconciliation statements with AI extraction and 12 deterministic detection rules — finding dollar amounts in your specific documents, not benchmarks.
