Mortgage Basics
Understanding the fundamentals of home financing empowers you to make the best decisions for your future.
Pre-Approval
Pre-approval is a lender's conditional commitment to loan you a specific amount based on your credit, income, and assets. It shows sellers you're a serious buyer and gives you a clear budget before you start shopping. Pre-approval is different from pre-qualification, which is a less formal estimate based on self-reported information.
Credit Score
Your credit score is a three-digit number that reflects your creditworthiness. Most mortgage programs require a minimum score — typically 620 for conventional loans and 580 for FHA loans. A higher score generally qualifies you for a lower interest rate, which can save you thousands over the life of the loan.
Fixed vs. Adjustable Rates
A fixed-rate mortgage keeps the same interest rate for the life of the loan, offering predictable monthly payments. An adjustable-rate mortgage (ARM) starts with a lower fixed rate for an initial period — commonly 5, 7, or 10 years — then adjusts periodically based on a market index. ARMs can be a smart choice if you plan to sell or refinance before the rate adjusts.
Loan Terms
The term is the length of time you have to repay the loan. The most common terms are 15-year and 30-year. A 30-year term offers lower monthly payments while a 15-year term means higher monthly payments but significantly less interest paid over time. Choosing the right term depends on your cash flow, financial goals, and how long you plan to stay in the home.
Down Payment
A down payment is the upfront portion of the home's purchase price that you pay out of pocket. While 20% is traditional, many loan programs allow much lower down payments — as low as 0% for VA and USDA loans, 3.5% for FHA loans, and 3% for some conventional programs. A larger down payment reduces your monthly payment and may eliminate the need for mortgage insurance.
Closing Costs
Closing costs are fees associated with finalizing your mortgage, including appraisal fees, title insurance, loan origination fees, and prepaid items like homeowner's insurance. They typically range from 2% to 5% of the loan amount. In some cases, these costs can be negotiated with the seller or rolled into the loan.
PMI (Private Mortgage Insurance)
If you put down less than 20% on a conventional loan, you will typically be required to pay PMI. This protects the lender — not you — in the event you default. PMI usually costs between 0.5% and 1.5% of the loan amount annually and can be removed once you reach 20% equity in the home.
Escrow
An escrow account is set up by your lender to collect and pay certain property-related expenses on your behalf, such as property taxes and homeowner's insurance. A portion of your monthly mortgage payment goes into this account. Escrow ensures these bills are paid on time and removes the burden of managing large annual payments yourself.
Debt-to-Income Ratio (DTI)
Your DTI is the percentage of your gross monthly income that goes toward monthly debt payments. Lenders use it to measure your ability to manage monthly payments and repay debts. Most conventional loans require a DTI of 45% or lower, though some programs allow up to 57%. Lowering your DTI before applying can significantly improve your chances of approval.
Interest Rate vs. APR
The interest rate is the cost of borrowing the principal loan amount. The APR (Annual Percentage Rate) is a broader measure that includes the interest rate plus fees and other loan costs, expressed as a yearly rate. When comparing loan offers, the APR gives you a more complete picture of the true cost of the loan.
Loan Types
Different loan programs are designed for different borrowers. Conventional loans are not government-backed and typically require stronger credit. FHA loans are government-insured and designed for buyers with lower credit scores or smaller down payments. VA loans are exclusively for eligible veterans and active military, offering no down payment and no PMI. USDA loans support homebuyers in eligible rural areas with zero down payment required.
Rate Lock
A rate lock is an agreement between you and your lender that guarantees a specific interest rate for a set period — typically 30 to 60 days — while your loan is being processed. Locking your rate protects you from market fluctuations before closing. If rates drop after you lock, some lenders offer a float-down option to capture the lower rate.
Amortization
Amortization is the process of paying off your loan through regular monthly payments over the loan term. In the early years of a mortgage, the majority of each payment goes toward interest rather than principal. Over time, this shifts so that more of each payment reduces your loan balance. Your lender can provide an amortization schedule showing the exact breakdown for every payment.
Home Appraisal
A home appraisal is an independent assessment of a property's market value conducted by a licensed appraiser. Lenders require an appraisal to ensure the home is worth at least as much as the loan amount. If the appraised value comes in lower than the purchase price, it can affect your financing and may require renegotiation with the seller.
Title Insurance
Title insurance protects both the lender and the buyer against any claims or disputes over ownership of the property. A lender's title policy is typically required and protects the lender's interest. An owner's title policy is optional but strongly recommended — it protects you if someone later challenges your ownership, such as in cases of undisclosed liens or errors in public records.
