Assume that your neighbor took a loan of $300,000 five years ago

Assume that your neighbor took a loan of $300,000 five years ago. At that time, she took a 30-year loan for 5.8%. She now wants to consider re-financing her loan. She went to a bank and was told that re-financing her loan for 30 years would cost her $6,500 upfront and re-financing her loan for 15 years would cost her $5,000 upfront. Your neighbor is low on cash and would prefer to add the upfront fees into her new loan. 
Your neighbor comes to seek your help with her mortgage dilemma. 
Can you use your Time Value of Money skills to help guide your neighbor if she should go for re-financing? You can guide her in terms of helping her understand her current interest expense versus future interest expense, current PMT versus future PMT, how a 15-year loan versus a 30-year loan would affect her finances, etc. Help her understand by giving her different scenarios so she can make a good decision that suits her best. You can get the current rates from any bank 
website by searching under Mortgage Rates. 
Provide your work using tables/graphs/explanations. Also, attach a PDF of the website you used to obtain the mortgage rates. 
Some hints: 
1. You need to prepare your own excel amortization tables to support your explanation and 
decision. Entering the numbers in the boxes in different websites and using those to get 
your answers cannot be accepted and does not serve the purpose of this extra credit 
assignment. 
2. You would prepare the 3 amortization tables (current loan, new 15-year loan, and new 
30-year loan) using monthly compounding just like how we solve using Chapter 4 
Amortization Notes. 
3. Also, when calculating the PV for the new 15-year and 30-year loans, note that it will not 
be $300,000 because the neighbor has already paid off some part of the loan amount in 
the previous 5 years. The PV for the new 15-year and 30-year loans will be balance still 
remaining on the current loan after 5 years (obtained from Balance Remaining at the end 
of Year 5) plus the upfront fees. 
4. You also need to provide a clear explanation of your excel work and provide an analysis 
for your findings. Your neighbor may not understand what the different amortization 
tables mean and how to read, analyze, and apply them. You need to give your 
recommendation under different scenarios for your neighbor in terms of when 15-year 
would be preferred or when 30-year would be preferred, etc. For example, compare the 
PMT under each option as it will directly affect the liquidity of your neighbor, compare 
the total interest amounts under each option. Based on what is important for the neighbor, 
she can make the correct decision that suits her situation.
