Bug Bastion Village, a student apartment complex, generates effective gross income of $26,000. Income tax savings are $12,500 (due to interest and depreciation expense, the owner's income tax liability for the year is $12,500 less than it would have been without the investment). There are no capital transactions, and all operating expenses were tax deductible. The after-tax cash flow to the equity investor was $13,800, and operating expenses equaled 90 percent of net operating income.
