7. You are a commercial real estate broker eager to sell an office build- ing. An investor is interested but demands a 20 percent return on her equity investment. The building's selling price is $10 million, and it promises after-tax cash flows of $1 million annually in perpetuity. Interest-only financing is available at 8 percent interest; that is, the debt requires no principal payments. The tax rate is 50 percent.

a. Propose an investment-financing package that meets the investor's return target.

b. Propose an investment-financing package that meets the investor's target when she demands an 80 percent return on equity.

c. Why would an investor settle for a 20 percent return on this in- vestment when she can get as high as 80 percent?
