To calculate the real cost of the house, we need the house price and the deposit percentage. Since the deposit is given as 8%, we can calculate the loan amount as follows:
Loan amount = House price - Deposit
Next, we need to calculate the monthly repayment amount. The interest rate is given as "Prime + 2%," where the prime rate is 9%. So the interest rate for the loan is 9% + 2% = 11%.
We can use the factor table provided in question 2.1 to find the factor for the interest rate. Let's assume the factor for 11% and a loan period of 20 years is 0.0115.
Monthly repayment amount = Loan amount / 1000 x Factor
Now we can calculate the real cost of the house:
Real cost = Monthly repayment amount x Number of repayments made
To calculate the effect of a 15% deposit instead of 8% on the real cost of the loan, we need to adjust the deposit percentage and recalculate the loan amount, monthly repayment amount, and real cost using the updated deposit percentage.
Please provide the house price and the actual factor values from the factor table so that I can perform the calculations for you.
