Mortgage Basics
Understanding mortgage payments, amortization, interest rates, and how extra payments save money.
What Is a Mortgage
A mortgage is a loan used to purchase real estate, where the property serves as collateral. The borrower makes regular payments (typically monthly) that include both principal repayment and interest.
Understanding how mortgages work is essential for making informed decisions about one of the largest financial commitments most people will ever make.
Key Mortgage Components
- Principal: The amount you borrow to purchase the property
- Interest: The cost of borrowing, expressed as an annual percentage rate (APR)
- Term: The length of the loan, typically 15 or 30 years
- Amortization: The process of paying down the loan over time through regular payments
Understanding Amortization
Amortization is the process of spreading out a loan into a series of fixed payments. Early in the schedule, a larger portion of each payment goes toward interest. Over time, more goes toward principal.
Amortization Example
A $300,000 mortgage at 6.5% for 30 years
Input
Monthly principal and interest: about $1,896.20
Result
Month 1: about $271.20 principal + $1,625.00 interest
The Power of Extra Payments
Adding even a small extra payment each month can save thousands in interest and reduce your mortgage term by years.

Types of Mortgages
- Fixed-Rate: Interest rate stays the same for the entire loan term. Predictable payments.
- Adjustable-Rate (ARM): Rate changes periodically based on market conditions. Lower initial rate but risk of increases.
- FHA Loans: Government-insured loans with lower down payment requirements.
- VA Loans: For eligible veterans and service members, often with zero down payment.
