Understanding Mortgages: A Complete Guide
A mortgage is a loan used to purchase real estate, where the property itself serves as collateral. If you stop making payments, the lender can seize the home through a process called foreclosure. Because the loan is secured by real property, mortgage interest rates are significantly lower than unsecured loans like credit cards or personal loans.
Types of Mortgages
Fixed-Rate Mortgages lock in your interest rate for the entire loan term. The most common options are:
- 30-Year Fixed — The most popular mortgage in America. Lower monthly payments spread over three decades, but you pay significantly more in total interest.
- 15-Year Fixed — The fastest way to build equity. Monthly payments are roughly 30% higher than a 30-year, but you save tens of thousands in interest and own your home free and clear in half the time.
Adjustable-Rate Mortgages (ARMs) start with a lower "teaser" rate for an introductory period (typically 5, 7, or 10 years), then adjust annually based on a market index.
Frequently Asked Questions
What credit score do I need for a mortgage? Conventional loans typically require 620+. FHA loans accept 580+ (with 3.5% down) or 500-579 (with 10% down). VA and USDA loans have no official minimum, but most lenders prefer 620+.
How much house can I afford? A common guideline is the 28/36 rule: your mortgage payment should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36%.
