Most companies use straight line depreciation. However, if you normally use a different depreciation method that EZLease supports, you may select it here and all new leases will automatically have that method. (You may always change the method for an individual lease.)
When you change the default depreciation method, you are given the option to change the depreciation method of all leases in the current database to the new default.
This option is selected in File/System Options.
