Key Concepts:
- Home Value: Current market value of your property
- Mortgage Balance: Remaining loan amount on your home

- Mortgage Balance: $150,000
- Max LTV: 80%
- Interest Rate: 6%
- Loan Term: 15 years
Step 1: Calculate Maximum Loan Amount
80% of $300,000 = $240,000
Step 2: Calculate Available Credit
$240,000 − $150,000 = $90,000
