Audit Landlord CAM Overcharges &
Protect Lease Operating Margins

Engineered for commercial tenants, corporate CFOs, retail franchisees, and commercial brokers. Reconcile annual common area maintenance, enforce cumulative expense caps, and export court-admissible audit dispute notices.

Pro-Rata Share & Gross-Up Audit

Verify tenant proportionate share formulas. Recalculate variable operating expenses against negotiated occupancy floors and base year anchors to catch unpermitted gross-up inflations.

Capital Expenditure & Cap Enforcement

Detect unamortized roof replacements, structural structural repairs, leasing commissions, and executive bonuses improperly billed as routine common area maintenance.

Formal Legal Dispute Notices

Export an itemized calculation worksheet from the figures saved on the lease. It is a draft for review, not a court filing and not legal advice.
