Principles of Finance Chapter 6 Homework Karen and Mike Harrington would like to add an in-ground pool complete with an outdoor built-in barbecue, a fire pit, and entertainment patio. They received quotes from multiple companies and decided to go with one that provided a quote of $85,000. They would like to start construction in 18 months. The Harrington's have the following plans in place in order to fund the project: 1. Currently have $14,000 in a money market account earning 4% monthly. 2. The Harrington's have committed to saving an additional $1800 a quarter in an account at their local credit union. The account pays 3% compounded quarterly. 3. They expect to receive an inheritance in 8 months. The amount they expect to receive is $30,000. The money will be placed in a separate stock account that they believe will earn 8% compounded monthly. 4. Any monies they are short at the time the construction begins will be supplemented with a home equity line of credit. How much must the couple borrow from the equity in their home? How much will their monthly payment be over 10 years if the bank charges 2.50% compounded monthly? This assignment must be completed in Excel complete with Excel Formulas. (Use the financial calculator function in Excel to complete this problem.)
