In the United States, a mortgage is a type of loan used to buy or refinance a home or real estate. When you take out a mortgage, you borrow money from a lender, and the home itself is used as collateral. This means if the loan is not repaid according to the agreement, the lender has the legal right to take back the property through a process called foreclosure.
This guide explains what a mortgage is, how it works in the U.S. market, and what first-time homebuyers should know, with clear explanations and easy-to-understand examples.
A mortgage is a loan used to purchase or refinance real estate, where the property itself serves as collateral for the loan.
In simple terms:
- A lender provides money to buy a home
- You agree to repay that money over time, plus interest
- If the loan is not repaid as agreed, the lender may have the right to take possession of the property through a legal process called foreclosure
In the U.S., mortgages typically have repayment terms of 15 or 30 years, though other terms may be available depending on the loan type and lender guidelines.
How Does a Mortgage Work in the U.S.?
When you get a mortgage, you are signing two key legal agreements:
1) Promissory Note (Your Promise to Repay)
This document states:
- How much money you borrowed
- Your interest rate
- Your loan term (for example, 30 years)
- Your monthly payment structure
Example: If you borrow $400,000, the promissory note explains how and when you must repay that amount plus interest.
2) Mortgage or Deed of Trust (The Home as Collateral)
This document gives the lender a legal claim on the property until the loan is fully paid off.
Simple explanation:
You own the home, but the lender has a legal interest in it until the mortgage is paid in full.
What Does a Monthly Mortgage Payment Include?
In the U.S., most mortgage payments include PITI:
P – Principal
The portion of your payment that reduces the loan balance.
I – Interest
The cost of borrowing money from the lender.
T – Taxes
Property taxes collected monthly and usually held in an escrow account.
I – Insurance
Homeowners insurance, also often paid through escrow.
Example:
Your total monthly payment might be $2,800, but only part of that goes to the loan itself—the rest covers taxes and insurance.
What About PMI or Mortgage Insurance?
- PMI (Private Mortgage Insurance) may apply to conventional loans when the down payment is below a certain threshold.
- FHA loans include mortgage insurance premiums (MIP).
These protect the lender—not the borrower.
Common Types of Mortgages in the U.S.
1) Fixed-Rate Mortgage
- The interest rate stays the same for the entire loan term.
- Predictable monthly payments.
Example: A 30-year fixed-rate mortgage gives you stable payments for long-term planning.
2) Adjustable-Rate Mortgage (ARM)
- Starts with a lower initial rate.
- The rate can change after the introductory period.
Example: A 5/1 ARM has a fixed rate for the first 5 years, then adjusts annually.
- Not directly insured by the government.
- Includes conforming and jumbo loans.
4) Government-Related Loan Programs
- FHA loans – flexible guidelines for many buyers
- VA loans – for eligible veterans and service members
- USDA loans – for qualifying rural areas
Eligibility and terms depend on credit, income, property type, and lender guidelines.

The Mortgage Process: Step by Step
Step 1: Pre-Approval
You share income, assets, debts, and credit info to estimate how much you may qualify for.
Example: A pre-approval helps sellers take your offer seriously.
Step 2: Loan Application & Loan Estimate
After applying, you receive a Loan Estimate, which outlines:
- Estimated interest rate
- Monthly payment
- Closing costs
This makes it easier to compare lenders.
Step 3: Underwriting & Appraisal
- Underwriting reviews your financial profile.
- Appraisal confirms the home’s value.
Step 4: Closing Disclosure & Closing
You receive a Closing Disclosure at least 3 business days before signing. This shows your final loan terms and costs.
Mortgage Costs to Be Aware Of
In addition to monthly payments, borrowers may encounter:
- Down payment
- Closing costs (lender fees, title, appraisal, taxes)
- Prepaid items (insurance, interest, taxes)
- Escrow account (used to manage taxes and insurance)
Tip: Always compare Loan Estimates side by side to understand the true cost—not just the interest rate.
How to Shop for a Mortgage the Smart Way
When comparing mortgage options, ask:
- Is the loan fixed or adjustable?
- What fees are included?
- Are lender credits available?
- What does my total monthly payment include?
Example: Two loans may have the same rate, but very different total costs.
