Loan Management System

[jiyajain]

We are building a banking application which tracks a customer on their loans.
1. A customer can have 3 types of Loans (Auto / Mortgage / Personal)
2. Auto loans contain make information (only GM/Ford/Tesla)
3. Customer can make payments for each loan.
4. A bank can levy late fees on a loan (adding to balance)
5. A bank needs the ability to find all Auto loans by make (ie all GM car loans)

Personal Loan Fico to Apr mapping:
0-600: 21.99%
601-720: 17.99%
721-850: 12.99%

John (1 GM auto loan)
Joe (1 Ford auto, 1 mortgage loan in NY)
Jill (1 Ford auto loan – joint with Megan, 1 mortgage in CA, 1 personal FICO score 820)

All personal loans start with outstanding balance of $5,000, term of 12 months and APR based off the FICO to APR mapping.

Scenarios: (print remaining balance of all loans after each scenario)
John makes a payment of $500 on his GM auto loan
Joe has two loans. Joe pays off his auto loan in full. Joe misses the mortgage payment and the bank charges a $100 late fee on his mortgage loan.
Jill makes payment of $425 on her auto loan, $1800 on her mortgage, and $1000 on her personal loan
Megan pays $800 toward Telsa auto loan and $1000 towards Ford auto loan and $2000 towards mortgage
Tiffany pays $1800 towards her one mortgage and $2000 on another mortgage
Adam pays $500 towards Tesla loan and $300 towards Ford loan. He also pays $250 towards his personal loans.
Jennifer attempts to pay $8,000 towards her personal loan. The bank should reject the payment because it exceeds the remaining balance.
