Like any specialized industry, a boatload of technical terms goes hand-in-hand with the mortgage world. For first-time home buyers, the process can feel overwhelming, with unfamiliar jargon being flung at you left and right.
But just because it can be a lot at once doesn't mean it has to be. We've compiled the most commonly used words and phrases pertinent to the home-buying process. Understanding these terms will help set you up for success as your home loan gets closer to the finish line.
Essential Mortgage Participants and Payments
Borrower / Co-Borrower
This is a simple one to start with. YOU are the borrower! A borrower is the person applying for the loan to purchase the property. If you are applying with a spouse or partner, they are the co-borrower.
Earnest Money
Often called a "good-faith deposit," this is the money you send to the seller to affirm your intent to purchase. This deposit is typically held in an escrow account and applied to your down payment or closing costs at the end. Learn more about the full process in our How It Works guide.
Down Payment
This is the upfront payment you make toward the home's purchase price. While many believe a 20% down payment is mandatory, many loan programs allow for as little as 3% or even 0% down for qualified buyers. Check out our VA loan options for 0% down programs, or explore USDA loans for rural property financing.
Understanding Your Loan Math
Equity
Equity is the difference between the current market value of your property and the amount you owe on your mortgage. Building equity is one of the key wealth-building benefits of homeownership.
Home Equity Line of Credit (HELOC)
A HELOC is a revolving line of credit secured by your home's equity. It works similarly to a credit card and is often used for large expenses like home renovations, debt consolidation, or even as a bridge loan when buying a new home. We offer a Hybrid Fixed-Rate HELOC with rate stability and flexibility.
Annual Percentage Rate (APR)
Note that APR is not the same as your interest rate. The APR reflects the total cost of borrowing, including the interest rate, points, and other lender fees, expressed as a yearly rate. Understanding APR is crucial—read our blog post on what determines mortgage rates for a deeper dive.
Debt-to-Income (DTI) Ratio
This is a key metric lenders use to determine your borrowing power. It is calculated by dividing your total monthly debt payments by your gross monthly income. Most conventional loans look for a DTI of 43% or lower . Use our affordability calculator to see how DTI affects your home buying power.
Loan-to-Value (LTV) Ratio
LTV is a mathematical calculation that compares the amount of your mortgage to the appraised value of the property. A higher LTV means more risk for the lender, which is why loans with LTV above 80% typically require PMI.
The Pre-Approval Process
Pre-qualification vs. Pre-approval
Pre-qualification is a quick, high-level estimate based on unverified financial info.
Pre-approval is a rigorous process where a lender verifies your credit, income, and assets. A pre-approval letter is essential in a competitive market to show sellers you are a serious buyer.

Underwriting
This is the "behind-the-scenes" phase where a lender evaluates the risk of the loan. An underwriter verifies all your documentation to ensure you meet the specific guidelines for the loan program. Our blog on Fannie Mae's credit score changes explains how underwriting guidelines have evolved.
Protection and Insurance
Private Mortgage Insurance (PMI)
If you put down less than 20% on a conventional loan, lenders usually require PMI . This protects the lender if you stop making payments. Use our monthly payment calculator to see how PMI affects your payment.
Homeowners Insurance
Lenders require you to have a policy that covers potential damages or losses to the home. This is separate from PMI and must be established before the loan closes.
Homeowners Association (HOA)
If you buy a condo or a home in a planned development, you may be part of an HOA. They collect dues to manage shared amenities and maintenance. HOA fees are factored into your DTI calculation.
Types of Mortgage Loans
Fixed-Rate Mortgage
Your interest rate remains the same for the entire life of the loan (e.g., 30 years). Great for long-term stability.
Adjustable-Rate Mortgage (ARM)
The interest rate may change periodically based on market fluctuations. Often starts with a lower rate.
Conventional Loans
Loans not insured by the federal government; they typically follow the standards set by Freddie Mac and Fannie Mae.Popular in California.

Reaching the Finish Line
Appraisal
A professional assessment of the home's value. Lenders require this to ensure the property is worth the amount of money they are lending you.
Closing Disclosure (CD)
This is a crucial five-page document provided at least three days before closing. It outlines your final loan terms, projected monthly payments, and how much you will pay in fees and closing costs.
Closing Costs
These are the fees paid at the end of the transaction. They typically range from 2% to 5% of the purchase price and include taxes, title insurance, and origination fees. Property taxes are a significant component—learn more in our property taxes guide.
Title Company
A neutral third party that ensures the property's "title" is clear of liens or disputes and handles the legal transfer of ownership.
Clear to Close (CTC) ✓
The three best words in real estate! This means the underwriter has given the final approval, all conditions are met, and you are ready to sign your final documents.
