What Is a Mortgage? How Does a Mortgage Work?
Buying a home is one of those milestones that can feel both exciting and a little overwhelming. You finally found a property you love, but now there’s talk of mortgage payments, interest rates, and down payments, and it all starts to sound like a different language.
The good news? It doesn’t have to be that way. Once you get the basics, a mortgage is simply a home loan from a lender that helps you finance your home purchase. We’ll walk you through everything, from what’s in a monthly payment to the types of loans you might consider.

What Is a Mortgage
A mortgage is a secured loan from a lender that helps you buy a home. Since most people don’t have the money to cover the full purchase price upfront, this type of loan lets you borrow a set amount of money and pay it back over time.
You agree to repay the loan amount, plus interest, through monthly payments over a set loan term. The home itself acts as collateral, which means the lender’s right allows them to take ownership of the property if you stop making your monthly payment.
This agreement is legally binding and is part of what’s called a promissory note, a document you sign during the mortgage process that outlines your repayment terms.
There are several types of mortgages, and the kind of loan you choose can affect your interest rate, monthly payment, and other costs.
A conventional loan is one of the most common choices. It’s not backed by the government and typically requires higher credit scores and larger down payments but offers flexible terms and competitive rates.
For borrowers needing more flexibility, government-backed loans provide added support. FHA loans usually allow lower credit scores and smaller down payments, making them popular among first-time buyers. VA loans offer exclusive benefits to eligible service members, veterans, and surviving spouses, including no down payment and favorable terms.
How Does a Mortgage Loan Work
When you apply for a home loan, your mortgage lender will look closely at your financial situation to decide whether to approve your mortgage application.
They’ll review your credit score, credit history, income, and debt-to-income ratio. Basically, they want to know if you can afford the monthly payment and how likely you are to pay back the loan.
Once approved, you’ll receive a Loan Estimate, a document that spells out all the details about your home loan, including your interest rate, total amount borrowed, monthly mortgage payment, and other costs like property taxes and insurance.
Reviewing this information carefully is important, it helps make sure there are no surprises later.
After closing, you’ll start making payments every month, typically for 15, 20, or 30 years, depending on your mortgage term. Staying on top of your mortgage payment is key, not only to avoid foreclosure but also to build home equity, the value of your home compared to what you still owe on your mortgage.
Over time, as your home’s value grows and you pay down your principal, your equity increases, giving you more financial flexibility down the road.
What’s in a Mortgage Payment
Every month, your mortgage payment covers more than just the money you borrowed to buy your home.
It’s made up of four key parts, often referred to as PITI: Principal, Interest, Taxes, and Insurance. Understanding how each piece works can help you better manage your monthly payment and plan for the life of the loan.
Principal
Principal is the set amount of money you borrowed from your mortgage lender to pay for your home. Each monthly payment chips away at this loan amount, helping you build home equity, the difference between your home’s value and what you still owe.
Early in your mortgage term, most of your payment goes toward interest, but over time, more of it will reduce your principal and increase the value of your home ownership.
Interest
Interest is the cost you pay for borrowing money from a lender. It’s calculated as a percentage of your loan amount and is a major part of your mortgage payment, especially in the early years.
Your interest rate depends on your credit score, credit history, and market condition when you apply. Borrowers with a higher credit score often get a lower interest rate, while those with a lower credit score might face a higher interest rate.
Taxes
Property taxes are charges from your local government based on the value of your home. These taxes help fund essential services like schools, police, and fire departments.
Your mortgage servicer usually collects this amount as part of your monthly payment and holds it in an escrow account until it’s time to pay the tax bill. Since property tax rates can vary and increase over time, your monthly payment could adjust slightly.
Insurance
Insurance includes two types: homeowner’s insurance and private mortgage insurance (PMI). Homeowner’s insurance protects your property and belongings against damage, natural disasters, and theft.
PMI is typically required if your down payment is less than 20% of the home’s purchase price. It protects the lender, not you, if you stop making payments. PMI costs vary but can often be removed once you build enough home equity.
Types of Mortgages
There are several types of mortgages, each designed to meet different needs. Knowing your options can help you choose the right kind of loan for your financial situation and work with the best mortgage lender for your home purchase.
Conventional Loan
A conventional loan is a mortgage that isn’t backed by a government agency like the Federal Housing Administration. It’s the most common type of mortgage in the United States and is typically offered by banks, credit unions, and other financial institutions.
Conventional loans often require a higher credit score and a larger lump sum down payment compared to other loan programs, but they may reward borrowers with a lower interest rate and more flexible mortgage terms.
These loans can be a good option if you have a strong credit report, stable finances, and funds available for a down payment. Since the Federal Housing Finance Agency sets limits on how much you can borrow, it’s important to review those limits based on your property’s location and price range.
Fixed-Rate Mortgage
A fixed-rate mortgage is one of the most common types of conventional loans. It offers a fixed monthly payment and an interest rate that stays the same for the entire loan term, typically 15, 20, or 30 years.
A 30-year fixed-rate mortgage is popular because it spreads your mortgage payment over a longer period, making your monthly payment more affordable.
This kind of loan can be a good idea if you prefer stability and want to protect your finances from unpredictable market conditions. Since your rate won’t change, you always know what to expect, helping you manage your bank account and plan your future with confidence.
Adjustable Rate Mortgage
An adjustable-rate mortgage (ARM) often starts with a lower interest rate than a fixed-rate mortgage, but the rate can change after an initial period. For example, a 5/1 ARM keeps the same rate for the first five years, then adjusts annually based on market conditions.
While the lower initial payment can free up funds for other financial goals, ARMs come with the risk of higher monthly payments later. Borrowers should review their financial information and consider their long-term finances before choosing this type of loan.
Consulting a mortgage lender or mortgage broker for legal advice about lender’s rights and the agreement details can help you understand the potential risks.
FHA Loan
FHA loans are backed by the Federal Housing Administration and are often a useful tool for first-time homebuyers or borrowers with lower credit scores.
These loans allow for a lower down payment option, sometimes as little as 3.5%, and offer competitive rates even to those with less-than-perfect credit history.
However, FHA loans require mortgage insurance, which protects the lender if you default. While this increases your monthly payment, it can be a good idea if you need help securing funds to buy a home.
An FHA loan can give you a path to homeownership when other mortgage terms might be out of reach.
VA Loan
VA loans, offered through the U.S. Department of Veterans Affairs, are available to veterans, active-duty service members, and certain military families.
These loans often come with lower interest rates and don’t require a down payment or mortgage insurance, making them a great option for those who qualify.
USDA Loan
USDA loans are backed by the Department of Agriculture and help borrowers in rural areas purchase homes. These loans often come with competitive rates and don’t always require a down payment, making them accessible to buyers with limited funds.
Borrowers must meet certain income requirements, and the property must be in an eligible rural location.
Jumbo Mortgage
A jumbo mortgage is a home loan that exceeds the limits set by Fannie Mae and Freddie Mac, as outlined by the Federal Housing Finance Agency.
These loans are often used to finance high-value properties and typically require a higher credit score, a larger lump sum down payment, and a more detailed review of your financial information.
The stricter requirements mean you’ll need a solid credit report, proof of bank account reserves, and a clear understanding of the lender’s rights before signing the agreement.
