(Unleveraged returns) You plan to invest $10,000 in a security, borrowing $6,000 of the cost from a friend, thus putting up $4,000 of your own money. The cost of debt is 12%, and there are no taxes. With this arrangement, you expect a return of 20% on your equity investment. What would your return be without the leverage? That is, what would your return be if the entire $10,000 was your own money?
