Examples of errors found
In our experience, there are two types of errors, which are uncovered during the lease audit process: intentional and unintentional. Intentional errors are purposeful deviations from the appropriate application. Unintentional errors include human and oversight errors and are primarily mistakes caused by misinterpretations, misjudgment, and/or carelessness. With the prospect of these errors within your lease charges, there is often more than enough of a reason to have a lease audit performed.

The following is a listing of the errors we most frequently observe during a lease audit process, many of which could be intentional or unintentional.

Operating expense errors

  • Inclusions of commonly excluded expenses, such as corporate overhead, leasing expenses and ground lease payments
  • Capital expenditure inclusions and misapplication of capital amortization periods
  • Gross-up miscalculations, specifically with math errors, occupancy calculations and landlord’s allocations of fixed versus variable expenses
  • Proportionate share miscalculations or expanding building sizes related to measurement standards
  • Above market related party overcharges
  • Management fee miscalculations and overcharges
  • Improper inclusions of expenses directly reimbursed by tenants
  • Improper capital expenditure inclusions and misapplication of capital amortization periods
  • Misallocations of shared expenses
  • Miscalculation of expense caps
  • The restricted application of profit components on expenses
  • Base year misapplication and/or calculations
  • The inclusion of the cost of utilities for vacant spaces
  • Missed indirect expense allocations - mainly to parking garages or other profit centers of a building
  • Improper inclusions of reserves

Real estate taxes

  • Missed indirect real estate tax expense allocations - mainly to parking garages or other profit centers of a building
  • Improper inclusion of personal property or income taxes
  • Failure to return tax refunds
  • Base year errors, typically on new buildings where taxes were not fully assessed in the base year
  • Proportionate share miscalculations

Above standard service and utility charges

  • The application of profit components when services are to be at landlord “cost”
  • Incorrect calculations of the cost of services
  • Incorrect or miscalculated rate applications
  • Miscalculation of meter multipliers related primarily to electricity
  • Above market related-party overcharges
