Sub-prime mortgages have played a significant role in the modern financial landscape, especially in the lead-up to the 2008 financial crisis. They originated in the early 1990s as a way to extend homeownership to individuals with poor credit histories, but their proliferation and misuse led to severe economic consequences.
Types/Categories
Sub-prime mortgages can be categorized based on their interest rate structures and repayment terms:
- Fixed-Rate Sub-Prime Mortgages: These have a fixed interest rate for the life of the loan.
- Adjustable-Rate Mortgages (ARMs): These start with a lower fixed rate that adjusts periodically based on market conditions.
- Interest-Only Loans: Borrowers pay only the interest for an initial period, with principal payments starting later.
- Negative Amortization Loans: Monthly payments may not cover all interest owed, causing the loan balance to increase over time.
Key Events
- Early 2000s Boom: Increased issuance of sub-prime mortgages as lenders sought higher returns.
- 2007-2008 Financial Crisis: Widespread defaults on sub-prime mortgages contributed to a global economic meltdown.
- Post-Crisis Regulation: Introduction of stricter lending standards and regulatory oversight to prevent future crises.

Mathematical Models and Formulas
In sub-prime mortgage calculations, lenders often use risk-based pricing models. One common formula for estimating the interest rate is:
