Mortgage basics at a glance
A mortgage is a home loan secured by the property you buy or refinance. You borrow money from a lender and agree to repay it under stated terms. Before choosing a loan, understand the amount borrowed, interest rate, repayment term, fees, and whether the rate or payment can change.
What Is a Mortgage?
A mortgage is financing used to purchase a home or, in some cases, borrow against a home you already own. The property serves as collateral for the debt. If the borrower does not meet the repayment obligations, the lender may have legal rights to pursue foreclosure under the loan documents and applicable law. The exact rights and process depend on the contract and jurisdiction.
The word “mortgage” is commonly used to describe the home loan as a whole. When comparing offers, focus on the loan amount, interest rate, points, closing costs, Annual Percentage Rate (APR), rate type, repayment term, and any special features. The Consumer Financial Protection Bureau’s mortgage overview explains the key terms to compare.
How Does a Mortgage Work?
- You choose a property and loan structure. The price, down payment, loan program, term, and rate structure shape the offer.
- You apply and provide documentation. The lender reviews information such as income, assets, debts, credit history, and the property.
- You receive written loan information. A Loan Estimate describes important terms and estimated costs for the application.
- You review and close. Before signing final documents, compare the terms, cash required to close, and payment obligations.
- You repay over time. Regular payments reduce the balance and pay interest. For a fully amortizing loan, scheduled payments are designed to repay the balance by the end of the term.
What Makes Up a Mortgage Payment?
The scheduled principal-and-interest payment is usually the core loan payment. Your total monthly housing outlay may also include property taxes, homeowners insurance, mortgage insurance, and other ownership costs. Some lenders collect taxes and insurance through escrow; other borrowers pay those bills directly.

Common Mortgage Loan Types
Loan programs have different eligibility rules, insurance or guarantee structures, costs, and down-payment options. A loan type is not automatically better because it has a familiar label; compare the written terms for the programs you may qualify for.
Conventional loans
Conventional loans are not insured or guaranteed by the federal government. Many conforming conventional loans may be purchased by Fannie Mae or Freddie Mac if they meet the applicable eligibility requirements. Conventional loans can have different down-payment and mortgage-insurance rules.
FHA-insured loans
FHA loans are insured by the Federal Housing Administration. They may be an option for some borrowers who need more flexible qualification or down-payment features, but they have program-specific requirements and mortgage-insurance costs. Review current FHA rules and your lender’s offer rather than assuming one down-payment threshold applies to everyone.
VA-guaranteed loans
VA loans are backed by the Department of Veterans Affairs and are available to eligible veterans, servicemembers, and certain surviving spouses. Eligibility, funding fees, and other terms depend on the borrower and the loan. Confirm eligibility and current program rules with the VA and lender.
USDA-backed loans
USDA Rural Development mortgage programs support eligible homebuyers and properties that meet the program’s location, income, and other requirements. The property’s location and household circumstances matter, so use the official USDA eligibility tools before relying on an assumption.
The CFPB provides an overview of conventional, FHA, VA, USDA, and other loan options. Program rules can change; this page does not list individual eligibility thresholds.
Loan Terms: 15 Years, 30 Years, and Other Options
The loan term is the scheduled time allowed to repay the mortgage. A 30-year term generally spreads repayment over more months, which often means a lower required principal-and-interest payment but more interest over the full schedule. A 15-year term generally has a higher monthly principal-and-interest payment and a shorter repayment period. Lenders may offer other terms too.
| Feature | Shorter term | Longer term |
|---|---|---|
| Scheduled payment | Usually higher | Usually lower |
| Time to repay | Less time | More time |
| Total interest, all else equal | Usually lower | Usually higher |
| Budget flexibility | Less room in the monthly budget | More room in the monthly budget |
Fixed-Rate and Adjustable-Rate Mortgages
With a fixed-rate mortgage, the interest rate is set for the loan term. The scheduled principal-and-interest payment generally remains level, although escrowed taxes and insurance can still change the total amount paid each month. With an adjustable-rate mortgage (ARM), the rate is fixed for an initial period and then can adjust at intervals under the contract. This can make future payments less predictable.
Read our detailed Fixed-Rate vs. Adjustable-Rate Mortgage guide before comparing these structures. The CFPB also explains how fixed rates and ARMs differ.
Mortgage Terms Worth Knowing
- Principal: the amount borrowed and still owed.
- Interest rate: the percentage cost of borrowing, before other loan charges are considered.
- APR: a broader annualized measure that reflects the interest rate plus certain other loan charges.
- Down payment: the portion of the purchase price paid up front rather than financed.
- Loan-to-value (LTV): the loan amount compared with the property value used by the lender.
- Amortization: paying down a loan through scheduled payments over time.
- Escrow: an account the servicer may use to collect and pay certain property-related bills, such as taxes and insurance.
- Mortgage insurance: insurance required by some loan programs or structures; it is not the same as homeowners insurance.
- Loan Estimate: a standardized disclosure that helps you understand and compare a mortgage offer.
How to Compare Mortgage Offers
Compare more than the headline interest rate or the advertised monthly payment. Request written offers for the same loan amount, program, term, down payment, occupancy, points, and rate-lock period whenever possible. Then compare the interest rate, APR, monthly principal and interest, estimated total monthly payment, mortgage insurance, origination costs, lender credits, and cash to close.
The CFPB Loan Estimate explanation shows where to find key loan details. Its guide to comparing and negotiating Loan Estimates recommends looking at the complete offer, including monthly costs and upfront charges.
A Practical Starting Checklist
- Review your household budget and decide on a comfortable total monthly housing cost—not just the maximum amount a lender might approve.
- Check your credit reports for errors and organize income, savings, and debt information.
- Learn which loan programs may fit your circumstances.
- Compare multiple written Loan Estimates using matching assumptions.
- Ask how the rate is determined, whether it is locked, how long the lock lasts, and what may cause the offer to change.
- Read the final documents and ask about unfamiliar or risky features before signing.

Mortgage Basics FAQs
Is a mortgage the same as a home loan?
In everyday use, the terms are often used interchangeably. A mortgage loan is the financing used to buy or borrow against a home, with the property serving as security for repayment.
What is the difference between a fixed-rate and adjustable-rate mortgage?
A fixed-rate mortgage keeps the interest rate set for the loan term. An ARM has an initial rate period and may adjust later according to its index, margin, adjustment schedule, and caps.
Is a 30-year mortgage always better than a 15-year mortgage?
No. A 30-year term usually has a lower required monthly principal-and-interest payment, while a 15-year term usually pays off faster and costs less in total interest if other terms are comparable. The payment must fit the household budget.
Does a mortgage payment include property taxes and insurance?
It depends on the loan and escrow arrangement. Some servicers collect these amounts with the monthly payment; some homeowners pay the bills directly. Check the Loan Estimate and servicing documents.
Does preapproval guarantee a mortgage?
No. A preapproval is not the same as final underwriting approval or a promise to lend. The lender still needs to verify the application, property, and conditions before closing.
Where can I compare mortgage offers?
Request and compare written Loan Estimates from multiple lenders for the same loan type and assumptions. Review both upfront costs and ongoing payments.
