What is the lease audit process? The entire lease audit process is a multi-step review that generally takes from two to six months to complete. It often includes negotiating with the landlord and verifying that overcharges are recouped. Nearly all RTG clients request that RTG complete all the steps in the entire process: from initial lease screening for feasibility, to lease audit, to recovery of funds from the landlord. For more detailed information about the actual steps of the process, and the intricacies for each one, please refer to the section of this website entitled "The Lease Audit Process."
