What is a lease audit? A lease audit is a systematic process comprised of the examination of all documents associated with your lease, invoices and other correspondance from the landlord, as well as data from other sources to determine whether charges assessed by the landlord under a tenant’s lease have been proper. RTG's goal is to identify errors and overcharges by landlords that will lead to rent refunds and future savings for tenants. A lease audit is also commonly referred to as a Rent Audit, a CAM Audit, an Escalation Expense Audit, Lease Compliance Consulting, or a Lease Review. Typically, we look closely at things like base rent, operating expenses, common area maintenance charges, real estate taxes, etc.
