Mortgages are simply loans that help you buy homes. They come with terms, interest rates, and monthly payments that depend on your credit profile, income, and the lender you choose. We'll walk you through every part of the process.

A mortgage is a loan you get from a lender (bank, credit union, or mortgage company) to help buy a home. Instead of paying the full cost upfront, you borrow money and repay it over time—with interest.

• Principal: The amount you borrow.
• Interest Rate: The cost of borrowing, expressed as a percentage.
• APR (Annual Percentage Rate): Includes your interest rate plus fees and costs.
• Term: How long you’ll repay the loan—usually 15 or 30 years.
• Escrow: An account used to pay your taxes and insurance.

Pro Tip: Always compare APRs—not just rates—to understand true costs.

This is where you find out how much house you can afford. A lender will check your income, debts, and credit.

“Pre-approval shows sellers you’re serious—and helps you shop smart.”

With your budget in mind, explore homes that fit. Try using Be My Neighbor for real listings curated by lending pros.

Once you find your home, you submit a full mortgage application—W-2s, bank statements, ID, and more.

This is the behind-the-scenes magic. Lenders verify everything and determine if you meet guidelines.

Your loan gets the green light—or you’ll need to submit more documents. Don’t worry—this is normal.
