Whether you are a first-time homebuyer or refinancing an existing mortgage, this tool gives you the information you need before you speak to a lender.
What Is a Mortgage Loan?
A mortgage is a secured loan used to purchase or refinance a home. The property itself serves as collateral, which means if you fail to make payments, the lender has the legal right to repossess the property through foreclosure. Mortgages in the United States are typically repaid over 15 or 30 years in equal monthly installments that cover both principal and interest.
In addition to principal and interest, your monthly mortgage payment may also include property taxes, homeowner's insurance, and private mortgage insurance (PMI) if your down payment is less than 20%.
How Does a Mortgage Work?
When you apply for a mortgage, the lender evaluates your credit score, income, employment history, and existing debts to determine how much you can borrow and at what interest rate. Once approved, you receive the loan amount to purchase the property. You then repay the loan in monthly installments over your chosen loan term.
For example, if you take a $300,000 mortgage at a 6.5% annual interest rate for 30 years, your monthly principal and interest payment would be approximately $1,896. Over 30 years, you would pay roughly $382,000 in total interest, making your total repayment about $682,000.
Types of Mortgage Loans in the USA
- Conventional Loan: The most common type, not backed by the government. Usually requires a credit score of 620 or higher and a down payment of at least 3% to 20%.
- FHA Loan: Backed by the Federal Housing Administration. Allows down payments as low as 3.5% and accepts lower credit scores, making it popular with first-time buyers.
- VA Loan: Available to eligible veterans and active military personnel. Offers no down payment requirement and competitive rates.
- USDA Loan: For eligible rural and suburban homebuyers. Offers 100% financing with no down payment required.
- Jumbo Loan: For loan amounts exceeding conforming loan limits, typically above $766,550 in most US counties for 2026.
Fixed-Rate vs Adjustable-Rate Mortgage
When choosing a mortgage in the USA, one of the most important decisions is whether to choose a fixed-rate or adjustable-rate mortgage:
- Fixed-Rate Mortgage: Your interest rate stays the same for the entire loan term. Your monthly payment never changes, making budgeting easier. Best for buyers who plan to stay in the home long-term.
- Adjustable-Rate Mortgage (ARM): Your rate is fixed for an initial period (such as 5 or 7 years) and then adjusts periodically based on market rates. Can offer lower initial payments but carries the risk of rising payments later.
Current Mortgage Rates in the USA – 2026
Mortgage rates fluctuate based on Federal Reserve policy, inflation, and broader economic conditions. Always check with multiple lenders for current rates. Here are typical ranges based on loan type:
- 30-year fixed: Typically ranges from 6% to 7.5% depending on credit profile
- 15-year fixed: Usually 0.5% to 0.75% lower than the 30-year rate
- 5/1 ARM: Often starts lower but adjusts after 5 years
How Much Down Payment Do You Need?
The down payment is the portion of the purchase price you pay upfront. A larger down payment reduces your loan amount, lowers your monthly payment, and eliminates PMI if you put down 20% or more.
- Conventional loan: Minimum 3% for first-time buyers, 5% for repeat buyers
- FHA loan: Minimum 3.5% with a credit score of 580 or higher
- VA and USDA loans: No down payment required
What Is Private Mortgage Insurance (PMI)?
If your down payment is less than 20% on a conventional loan, lenders typically require PMI. This is an additional monthly cost that protects the lender if you default. PMI typically costs between 0.5% and 1.5% of the loan amount per year. Once your equity reaches 20%, you can request to cancel PMI.
15-Year vs 30-Year Mortgage — Which Is Right for You?
The two most common mortgage terms in the United States are 15 years and 30 years. Each has advantages depending on your financial situation:
- 30-year mortgage: Lower monthly payments, more cash flow flexibility, but significantly more total interest paid over the life of the loan
- 15-year mortgage: Higher monthly payments, but much less total interest and the loan is paid off in half the time
Use our mortgage calculator to compare both scenarios and see the difference in total interest paid.
How to Qualify for a Mortgage in the USA
- Credit score: Minimum 620 for conventional loans; 580 for FHA loans
- Debt-to-income ratio (DTI): Most lenders prefer a DTI below 43%
- Stable employment: Typically two years of consistent employment history
- Down payment: Sufficient savings for down payment and closing costs
- Property appraisal: The home must appraise at or above the purchase price
What Are Closing Costs?
Closing costs are fees paid at the time of settlement, typically ranging from 2% to 5% of the loan amount. Common closing costs include loan origination fees, appraisal fees, title insurance, attorney fees, and prepaid property taxes and insurance. These costs are separate from your down payment and should be factored into your home buying budget.
Frequently Asked Questions
How much mortgage can I afford?
A common guideline is to keep your total housing payment below 28% of your gross monthly income. Use our mortgage calculator to test different loan amounts and rates to find a payment that fits your budget.
What credit score do I need to buy a house in 2026?
A credit score of 620 or higher is typically required for a conventional mortgage. FHA loans accept scores as low as 580. Higher scores unlock better interest rates and lower monthly payments.
Can I get a mortgage with student loan debt?
Yes. Student loan debt is factored into your debt-to-income ratio. As long as your DTI remains within acceptable limits, student loans do not disqualify you from a mortgage.
