For this you will have to search for your dream house, calculate the down payment, and the monthly payments for a 30 and 15 years fixed loan. You will use the loan payment formula to determine your monthly payments for a 30-year fixed loan with an APR of 3.75% and for a 15-years fix loan with an APR of 2.97% with a down payment of 5%. You will make a decision on which loan you would take and provide reasons for your choice based on comparing the monthly payment amounts and the total interest paid amounts.
