Suppose you bought a condo for $100,000 financing it with a $20,000 down payment of your own funds and an $80,000 mortgage loan from a bank. (10 points) a. Assume that the market value of your condo has now risen to $120,000. Ignoring interest and other costs, and assuming the loan amount is still $80,000, calculate your rate of return on your asset (ROA) and your rate of return on equity (ROE). b. Now assume that, instead of (a), you only put down $10,000 and borrowed $90,000 to buy the condo. Assuming that the market value of your house has risen to $120,000 and ignoring interest and other costs, calculate your rate of return on your asset (ROA) and your rate of return on equity (ROE). c. Now, instead of (a) or (b), suppose the value of the condo fell from $100,000 to $70,000. Assuming you paid $100,000, financing it with $20,000 of your own money and $80,000 with a mortgage loan, and ignoring interest and other costs, calculate your rate of return on your asset (ROA) and your rate of return on equity (ROE). What is the value of your equity stake in the condo after the price fall?
