1. Calculate the realized annual net returns for the house prices in Boston. (2 points) 2. Calculate the average realized net return and its standard deviation from 2010 to 2020.

Is it worthwhile to borrow to buy a house in Boston? Why? (2 points) 4. How does the return on your levered investment vary with the leverage, D/E? Provide the formula and a plot. (2 points) 5. How does the standard deviation of your levered investment vary with D/E? Derive the formula. Compare it with the standard deviation of house price returns.
