A couple has decided to purchase the $375,000 home they were considering. They will be taking out a conventional mortgage since their down payment of $75,000 represents 20% of the value of home. The couple obtains a $300,000 closed mortgage with a 5-year mortgage term that is amortized over 25 years at an interest rate of 6%, compounded semi-annually. Their monthly mortgage payment will be $1919.42. I have problem in calculating the $1919.42 without using a financial calculator.
