Financing a house means borrowing money from a lender to buy a home, then paying that money back over time with interest. Instead of paying the full purchase price in cash, you put down a portion upfront and take out a loan, called a mortgage, to cover the rest. The home itself serves as collateral for the loan, meaning the lender can take the property through foreclosure if you stop making payments.
How the Loan Is Structured
When you finance a home, you agree to repay the borrowed amount (the principal) plus interest over a set number of years, most commonly 15 or 30. Your interest rate determines how much the lender charges you for the privilege of borrowing. On a 30-year mortgage for $300,000 at 7% interest, you’d pay roughly $2,000 per month in principal and interest alone, and you’d end up paying nearly $419,000 in total interest over the life of the loan.
Early in the loan, most of your monthly payment goes toward interest rather than reducing your balance. This gradually shifts over time so that by the final years, the bulk of each payment chips away at the principal. This process is called amortization.
What Your Monthly Payment Covers
Your monthly mortgage payment typically includes four components, often referred to as PITI: principal, interest, taxes, and insurance. Principal and interest go directly toward repaying your loan. Property taxes and homeowners insurance are often collected by your lender each month and held in an escrow account, a dedicated holding account that your lender uses to pay those bills on your behalf when they come due.
If your down payment is less than 20% on a conventional loan, you’ll also pay private mortgage insurance (PMI), which protects the lender if you default. FHA loans carry a similar cost called a mortgage insurance premium. These extra charges can add $100 to $300 or more to your monthly bill depending on the loan amount.
Cash You Need Upfront
Financing a house doesn’t mean you avoid paying cash entirely. You’ll need money for two big upfront costs: the down payment and closing costs.
Down payment requirements depend on the type of loan. Conventional mortgages allow as little as 3% to 5% down, though putting down 20% eliminates PMI. FHA loans require a minimum of 3.5% down with a credit score of 580 or higher, or 10% down if your score falls between 500 and 579. VA loans, available to active-duty military members, veterans, and eligible military spouses, require no down payment at all. USDA loans, designed for buyers in eligible rural areas, also offer zero-down financing.
Closing costs cover lender fees, appraisal charges, title insurance, and other transaction expenses. These typically run 2% to 5% of the home’s purchase price. On a $400,000 home, that means $8,000 to $20,000 in addition to your down payment.
What Lenders Look At
To approve your financing, a lender evaluates three main things: your credit score, your debt-to-income ratio, and your income stability.
Your credit score signals how reliably you’ve handled debt in the past. Conventional loans generally require a minimum score of 620. FHA loans accept scores as low as 500, though the required down payment increases at lower scores. VA and USDA loans don’t have official government-set minimums, but most lenders want to see at least 620 to 640.
Your debt-to-income ratio (DTI) measures how much of your gross monthly income goes toward debt payments, including the new mortgage. Conventional lenders prefer a DTI at or below 45%, though borrowers with strong credit may qualify with a ratio up to 50%. FHA loans cap DTI at 43% in most cases. VA and USDA loans generally set the limit at 41%, with some exceptions for borrowers who have compensating strengths like cash reserves or a high credit score.
Income verification is straightforward for salaried employees: recent pay stubs, W-2 forms, and two years of tax returns. Self-employed borrowers face more scrutiny. Most loan programs require two years of personal and business tax returns, and some lenders also want to see a current profit and loss statement.
Types of Financing
The loan you choose affects your interest rate, down payment, and total cost. Here are the main options:
- Conventional loans are not backed by the federal government. They offer competitive rates for borrowers with good credit (620 or higher) and typically require at least 3% to 5% down. They’re the most common choice for buyers with solid credit histories.
- FHA loans are insured by the Federal Housing Administration and designed for buyers with lower credit scores or smaller savings. The trade-off is mandatory mortgage insurance for the life of the loan if you put down less than 10%.
- VA loans are guaranteed by the Department of Veterans Affairs. They stand out for requiring no down payment and no ongoing mortgage insurance, making them one of the most affordable financing options available to eligible borrowers.
- USDA loans are backed by the U.S. Department of Agriculture for homes in qualifying rural and suburban areas. Like VA loans, they offer zero-down financing, though household income must fall below certain limits for the area.
Fixed Rate vs. Adjustable Rate
Beyond choosing a loan program, you’ll pick between a fixed-rate and an adjustable-rate mortgage (ARM). A fixed-rate loan locks in the same interest rate for the entire repayment period. Your principal and interest payment never changes, which makes budgeting predictable.
An adjustable-rate mortgage starts with a lower interest rate for an introductory period, often 5 or 7 years, then adjusts periodically based on market conditions. Your payment could go up or down after the introductory window ends. ARMs can save you money if you plan to sell or refinance before the rate adjusts, but they carry the risk of higher payments down the road.
What Happens After You Close
Once financing is in place and you close on the house, you own the property, but the lender holds a lien on it until the mortgage is fully repaid. That lien is what gives the lender the legal right to foreclose if you default. With a non-recourse loan, the lender can only seize the home itself. With a recourse loan, the lender can also pursue your other assets or garnish wages to recover the remaining debt.
You’ll make monthly payments for the life of the loan unless you pay it off early, refinance into a new mortgage, or sell the home. When you sell, the proceeds first go toward paying off your remaining loan balance, and you keep whatever is left. The portion of the home’s value that you actually own, your equity, grows over time as you pay down the principal and as the property appreciates in value. Building equity is one of the central financial benefits of financing a home rather than renting.
