Unit 6: Credit & Debt

Loan Mechanics
Every loan is just four variables fighting each other. This lesson breaks down how principal, interest rate, term, and down payment interact — and why amortization means you pay mostly interest first.

Loan Types
Not all loans are created equal—a mortgage and a payday loan share a name but live in different financial universes. This lesson explores secured vs. unsecured loans, common loan types, and loan structures.

Mortgages & Amortization
A 30-year mortgage costs more in interest than the house itself—and most buyers never realize it. This lesson unpacks how amortization quietly front-loads interest, why down payments and PMI matter, and how a few extra dollars can save tens of thousands.
