**Question 408** leverage, portfolio beta, portfolio risk, real estate, CAPM

You just bought a house worth $**1,000,000**. You financed it with an $**800,000** mortgage loan and a deposit of $**200,000**.

You estimate that:

- The house has a beta of
**1**; - The mortgage loan has a beta of
**0.2**.

What is the beta of the equity (the $200,000 deposit) that you have in your house?

Also, if the risk free rate is **5**% pa and the market portfolio's return is **10**% pa, what is the expected return on equity in your house? Ignore taxes, assume that all cash flows (interest payments and rent) were paid and received at the end of the year, and all rates are effective annual rates.
