Chapter 5 Cost of Capital and Capital Structure


Leverage (work with at least one other)


Leverage is an important concept for making money. Using leverage in banking allows you to make money on borrowed money.


I want to see how well you can use leverage on your own and as a group. I recommend you try this on your own first; then get a group together to compare notes and see what your best option is.



You can do the following (any combination):


Small houses cost $100,000 and gain in value by 9% per year.

Medium houses cost $150,000 and gain in value by 10% per year.

Big houses cost $350,000 and gain in value by 11% per year.

Putting money in the bank gains 7% per year.

You can also do nothing; put it under your mattress if you want. (Inflation will definitely get you this way.


Explain how you will work with your money, why and how much you made. Again, I advise you to do it on your own, ask questions amongst yourselves, and then come up with the best answer.
