From APR and escrow to loan-to-value ratios and interest rate locks, this guide explains the mortgage terminology that plays a critical role in the loan approval process.

What Is a Mortgage?

mortgage is a loan used to purchase a home, where the property serves as collateral. While the concept seems simple, the process involves numerous moving parts, all tied to specific financial and legal terms.

To make it easier, we’ve grouped the most important terms into the categories below:

Core Mortgage Terms Explained

Term Definition
Amortization Scheduled payments over time that reduce the loan balance. Early payments primarily cover interest; later ones lower the principal.
APR (Annual Percentage Rate) Reflects the full cost of borrowing, including interest and fees—providing a clearer cost comparison than the interest rate alone.
Principal The original amount you borrow, excluding interest.
Interest Rate The percentage charged on the loan’s balance. Determines total interest paid over the life of the loan.
Loan Term The duration of your loan, usually 15 or 30 years.

Home Value and Equity Terms

Term Definition
Appraisal An unbiased assessment of your home’s market value, used by lenders to ensure the loan doesn’t exceed property value.
Assessed Value Value assigned by your local tax authority for property tax purposes—often different from the appraised market value.
Equity The difference between your home’s market value and your outstanding mortgage balance.
Appreciation An increase in your home’s value due to market conditions or improvements.
Loan-to-Value Ratio (LTV) A percentage comparing your loan amount to your home’s value. Lower LTV usually means better loan terms.

Loan Process and Approval Terms

Term Definition
Pre-Approval A conditional offer from a lender stating how much you can borrow, based on a review of your finances.
Debt-to-Income Ratio (DTI) A key metric showing how much of your monthly income goes toward debt. Lenders prefer a DTI under 43%.
Down Payment The upfront cash paid toward the home’s price. Commonly ranges from 3% to 20%.
Closing Costs Additional fees due at closing, including title fees, insurance, taxes, and lender charges—typically 2% to 5% of the loan.
Earnest Money A deposit showing you’re serious about buying. It’s held in escrow and applied to your closing costs or down payment.

Mortgage Types and Features

Term Definition
Fixed-Rate Mortgage Keeps the same interest rate for the life of the loan. Predictable monthly payments.
Adjustable-Rate Mortgage (ARM) Has a variable interest rate after an initial fixed period. Rates are affected by economic trends.
Balloon Mortgage Features low payments initially, followed by one large lump-sum payment at the end of the loan term. Riskier for most buyers.
