I need to also answer the following questions using the excel files provided and this website: [login to view URL] What would be the rental yearly margin, calculated as: ( yearly revenue - yearly costs )/ purchase price? Assuming costs are 2000€ per year Calculate the price for a 50 square meter property, and consider the following loan Capital: 50% of the purchase price excluding taxes Duration: 10 years (start date 1/1/2018 end date 31/12/2018) There’re two types of mortgages available: Fixed interest rate of 3% Variable interest rate of EURIBOR+1,25 Calculate the loan monthly payment by December 2028 for the fixed interest rate. Using a 10 year forecast of EURIBOR, calculate the loan monthly payment by December 2028 Which type of interest is more efficient for this scenario? Which duration makes one mortgage more appealing than the other? How much capital is it necessary to repay in a one-off payment by 2021, so the monthly payments for both loans to be the same? - Create a new scenario changing the variables: - Fixed interest rate of 2% - Variable interest rate of EURIBOR+0,99 - Duration: 20 years - What would be the interest rate that makes the loan monthly payments equals to 500€?
