Buying a home is one of the biggest financial decisions most people will ever make. A mortgage allows you to purchase a home by borrowing money from a lender and repaying it over time with interest. Understanding how mortgages work helps you choose the right loan and save tens of thousands of dollars over the life of your loan.

Fixed-rate mortgages keep the same interest rate for the entire loan term, giving you predictable payments. Adjustable-rate mortgages (ARMs) start with a lower rate that changes periodically based on market indexes. Government-backed loans (FHA, VA, USDA) offer lower down payment requirements for eligible borrowers.
Lenders evaluate your credit score (typically 620+ for conventional loans), debt-to-income ratio (ideally below 43%), employment history, and down payment. A higher credit score and larger down payment result in better interest rates and lower monthly payments.
Start by getting pre-approved, which shows sellers you're a serious buyer. Then shop for homes within your budget, make an offer, and complete the full application. The lender will order an appraisal and title search before issuing a final approval and scheduling closing.
Beyond the principal and interest, your monthly payment may include property taxes, homeowner's insurance, and PMI (if your down payment is under 20%). Closing costs typically add 2–5% of the loan amount. Over a 30-year loan, total interest paid can exceed the original loan amount.
Making extra principal payments reduces your loan balance faster and saves significant interest. Refinancing when rates drop can lower your payment or shorten your term. Even one extra payment per year can cut years off a 30-year mortgage.
