Understanding Mortgage Terms Before You Buy

Buying a home is one of the most significant financial decisions you’ll ever make—and for most people, it means taking out a mortgage. However, the home financing process is filled with terminology that can be confusing or overwhelming if you’re not familiar with it.

By learning key mortgage terms in advance, you’ll feel more confident navigating the homebuying journey—and be better prepared to make informed financial decisions.

In this guide, we’ll break down the most important mortgage terms to understand before you apply for a loan.

Mortgage

Definition: A mortgage is a loan from a financial institution that helps you purchase a home. You agree to repay the loan over time—typically 15 to 30 years—plus interest.

Considerations: If you fail to make your payments, the lender can foreclose on your home. Mortgages come in several types, including fixed-rate and adjustable-rate loans.

Principal

Definition: The principal is the amount you borrow from the lender to buy your home.

Considerations: The larger your down payment, the smaller your principal—and the less interest you'll pay over time.

Interest Rate

Definition: The interest rate is the cost of borrowing money, expressed as a percentage of the principal.

Considerations: Lower interest rates reduce your total repayment. Rates are based on your credit score, income, loan type, and market conditions.

Annual Percentage Rate (APR)

Definition: The APR includes both the interest rate and any lender fees, giving you a better idea of the loan’s total cost.

Considerations: Use APR—not just the interest rate—when comparing mortgage offers.

Fixed-Rate Mortgage

Definition: A mortgage with an interest rate that remains the same for the life of the loan.

Considerations: Ideal if you want stable, predictable monthly payments over time.

Adjustable-Rate Mortgage (ARM)

Definition: A mortgage with an interest rate that changes periodically after an initial fixed period (e.g., 5 or 7 years).

Considerations: ARMs often start with lower rates but can increase significantly depending on the market.

Loan Term

Definition: The length of time you have to repay the loan—commonly 15, 20, or 30 years.

Considerations: Shorter terms often come with lower interest rates and cost less over time, but have higher monthly payments.

Amortization

Definition: Amortization is how your loan payments are split between principal and interest over time.

Considerations: Early payments go mostly toward interest. Over time, more goes toward the principal.

Down Payment

Definition: The initial amount you pay upfront when purchasing a home.

Considerations: Typically 3%–20% of the purchase price. A larger down payment lowers your loan amount and can eliminate the need for PMI.

Private Mortgage Insurance (PMI)

Definition: Insurance that protects the lender if you default on your loan—typically required if you put down less than 20%.

Considerations: PMI adds to your monthly cost but can be canceled once you build 20% equity.

Escrow

Definition: An escrow account is used to hold funds for property taxes and homeowners insurance, which are paid by your lender on your behalf.

Considerations: Your monthly mortgage payment may include escrow costs, even though it’s not part of your principal or interest.

Closing Costs

Definition: One-time fees due at closing, including appraisal, attorney, title, and loan origination fees.

Considerations: Typically 2–5% of the loan amount. Review these closely in your Loan Estimate and Closing Disclosure.

Loan Estimate

Definition: A 3-page document provided by your lender within 3 days of applying for a mortgage.

Considerations: It details the loan terms, projected payments, and estimated closing costs. This helps you compare lenders and stay informed.

Closing Disclosure

Definition: A 5-page document provided 3 days before closing that confirms the final details of your loan.

Considerations: It should closely match your Loan Estimate. Review it thoroughly and ask questions if anything has changed.

Pre-Approval

Definition: A lender reviews your credit and finances to determine how much you can borrow.

Considerations: Shows sellers you're serious and can afford the home—often required when submitting an offer.

Pre-Qualification

Definition: A less formal estimate of how much you might qualify to borrow based on basic financial information.

Considerations: Helpful early in your home search, but not as solid as pre-approval.

Loan-to-Value Ratio (LTV)

Definition: The ratio of your loan amount to your home’s appraised value.

Considerations: Lower LTVs may get better interest rates and avoid PMI. For example, a $200,000 loan on a $250,000 home has an LTV of 80%.

Debt-to-Income Ratio (DTI)

Definition: Compares your monthly debt payments to your gross income.

Considerations: Lenders use DTI to assess your ability to manage mortgage payments. Aim for a DTI of 43% or less.

Appraisal

Definition: An evaluation of your home’s value by a licensed appraiser.

Considerations: Lenders require this to ensure the home is worth the purchase price. A low appraisal can impact loan approval.

Flood Certification

Definition: A document that determines if a home is in a FEMA-designated flood zone.

Considerations: If the home is in a flood zone, you’ll be required to purchase flood insurance—which may impact your budget.

Title Insurance

Definition: Protects the lender (and optionally the buyer) against issues with the property’s title—like liens or ownership disputes.

Considerations: A one-time fee at closing, but important for protecting your ownership rights.

Points (Discount Points)

Definition: Optional upfront payments that reduce your interest rate. One point typically equals 1% of your loan amount.

Considerations: If you plan to stay in the home long-term, buying points can save money over time.

Origination Fee

Definition: A fee charged by the lender to process your loan, often around 0.5%–1% of the loan amount.

Considerations: This is part of your closing costs. Compare origination fees when shopping lenders.

Underwriting

Definition: The process where the lender verifies your financial information and assesses the risk of approving the loan.

Considerations: Underwriting can take several days to a few weeks. Provide requested documentation promptly to keep things moving.

Refinance

Definition: Replacing your current mortgage with a new one—typically to get a lower rate, change your term, or cash out equity.

Considerations: Refinancing can reduce monthly payments or save interest, but it comes with closing costs.

Equity

Definition: The difference between your home’s value and your mortgage balance.

Considerations: As you pay down your loan and your home’s value rises, you build equity—which can be borrowed against with a HELOC or used when selling.

Homeowners Insurance

Definition: Insurance that covers damage to your home and personal belongings.

Considerations: Required by lenders and included in your escrow. Be sure your coverage is adequate for your location and home value.

Buyer’s Agent Commission

Definition: The fee paid to your real estate agent, typically by the seller, though recent regulation changes may shift responsibility to the buyer.

Considerations: Always clarify who is responsible for paying this fee before signing a contract. It may now need to be negotiated directly with your agent.
