How to Buy a House: The Complete Guide

Buying a home is the largest financial decision most people ever make, and the process has more moving parts than any guide you will find in a bank lobby. In 2026, the average American home costs about $351,000, mortgage rates sit in the mid-to-high single digits, and buyers face a market where preparation matters more than timing. This is the full path, in order, with the numbers that actually matter — from your first budget calculation to the day you get the keys and the years after.

Step 1: Know your real budget before you look

Most buyers start by browsing listings online. That is backwards. The first number to know is your monthly housing budget, not the listing price, because the listing price is only the beginning of what you pay every month. Your real cost is PITI: principal, interest, property tax and home insurance, plus a reserve for maintenance.

The industry standard is the 28% rule. It says your total housing payment should stay under 28% of your gross monthly income. On a $100,000 salary, that is $100,000 divided by 12, times 0.28, which equals about $2,333 a month. That $2,333 has to cover principal, interest, tax and insurance — not just the loan.

Backing out typical tax and insurance in an average-tax state, a $2,333 monthly budget supports roughly a $350,000 home at current rates. If you earn $60,000, your 28% ceiling is $1,400 a month, which supports about a $200,000 home. If you earn $200,000, you have about $4,667 a month, good for a $750,000 home in an average market.

The precise number depends on your interest rate, your local tax rate and your down payment — three variables no rule of thumb can nail down. Use our salary calculator to convert your exact income into a home price, then compare it against our state and city pages to see what that budget actually buys where you want to live. A $350,000 budget goes far in Ohio but barely covers a condo in California.

Step 2: Fix your credit and save the down payment

Your credit score and your down payment decide two things: whether you qualify, and what your rate will be. They are the two levers you control, and together they change your monthly payment by hundreds of dollars.

Credit comes first because it takes time to move. A FICO score of 760 or higher earns the best advertised rates. Scores from 700 to 759 pay slightly more. Below 620, conventional loans become hard to get and FHA becomes your main route. The gap between a 660 and a 760 score can cost half a percentage point or more, which on a $400,000 loan is roughly $40,000 over 30 years. That is the cheapest money you will ever make, and it is earned by paying bills on time and keeping credit card balances low for six to twelve months before you apply.

Down payments are more flexible than most people realize. Conventional loans start at 3% down, FHA loans at 3.5%, and VA or USDA loans at 0% for those who qualify. The catch is that any down payment under 20% triggers mortgage insurance — PMI on conventional loans, MIP on FHA — which adds 0.5% to 1.5% of the loan each year. On a $350,000 loan with 5% down, that is roughly $150 to $300 a month in extra cost.

The 20% down payment everyone talks about is not a requirement; it is simply the amount that removes mortgage insurance and maximizes your equity. Whether it is the right move depends on your savings and your market. We cover this in depth in our down payment guide.

Step 3: Get pre-approved, not just pre-qualified

There is a meaningful difference between pre-qualification and pre-approval, and sellers know it. Pre-qualification is an informal estimate based on numbers you type in yourself. Pre-approval is a lender actually verifying your income, assets, credit and debts, and committing to lend you up to a specific amount.

Pre-approval matters for two reasons. First, it tells you the true ceiling of what you can borrow, so you stop wasting time on homes outside your reach. Second, it signals to sellers that you are a serious buyer whose financing will not fall through. In a competitive market, an offer without a pre-approval letter often goes straight to the bottom of the pile.

Before you apply, gather your documents: two years of tax returns, recent W-2s and pay stubs, bank statements for the last two to three months, and any documentation of other assets or income. Applying with everything ready makes the process faster and prevents the back-and-forth that delays closing.

Step 4: Study the market before you shop

Home prices vary more by location than almost anything else in the economy. The most expensive states average $835,000 in Hawaii and $735,000 in California, while the cheapest average $145,000 in West Virginia and $170,000 in Mississippi. The national average is about $351,000. Your budget means completely different things in different zip codes.

Market	Average home price	What a $2,333/mo budget buys
West Virginia	$145,000	Plenty of room
Mississippi	$170,000	Comfortable
Ohio	$210,000	Comfortable
National average	$351,000	About right
Massachusetts	$580,000	Tight
California	$735,000	Stretch required
Hawaii	$835,000	Out of reach

Knowing your local market prevents both overpaying and under-budgeting. Study recent sales of comparable homes in your target area, not just asking prices. Asking prices are hopes; sold prices are facts. Our state and city pages give you the average price, tax rate and insurance cost for every state and 110 major cities, so you can ground your search in real local numbers before you visit a single open house.

Step 5: Find a home and make a smart offer

Once your budget and market knowledge are solid, the search becomes disciplined. Define your must-haves versus nice-to-haves before you look — the things you cannot change cheaply (location, layout, lot size) matter more than the things you can (paint, fixtures, appliances).

When you find the right home, your offer goes in with the pre-approval letter attached. Expect to negotiate on price, closing costs and contingencies. A contingency is a condition that lets you back out without losing your deposit — the two most important are the inspection contingency and the financing contingency.

In a hot market, buyers are tempted to waive the inspection contingency to win a bidding war. Resist that. Waiving inspection means you buy the home as-is, and a foundation problem, a failing roof or outdated electrical can cost tens of thousands after closing. The downside of losing a bidding war is a few more weeks of searching; the downside of a waived inspection is a money pit. In a slow market, you have more leverage to ask the seller for repairs or a price reduction.

Step 6: Inspect, appraise and lock your rate

After your offer is accepted, three things happen in parallel. First, you order a home inspection — a licensed inspector walks the property and reports on its condition. Attend the inspection if you can, and ask questions. The report is your negotiation tool: significant defects let you ask the seller to fix them, credit you at closing, or lower the price.

Second, your lender orders an appraisal. The appraisal is an independent estimate of the home's value, and it protects you from overpaying and the lender from lending more than the home is worth. If the appraisal comes in low, you either renegotiate the price, bring more cash to closing, or walk away.

Third, lock your interest rate. Rates move daily, and a lock freezes your rate for a set window — typically 30 to 60 days — so it cannot rise while you work toward closing. Lock when you are comfortable with the rate and confident you will close on time. Floating and hoping for a dip can work, but it can also cost you if rates rise.

Step 7: Close and budget for what comes next

Closing is the final meeting where you sign the mortgage documents, pay your down payment and closing costs, and receive the keys. Closing costs run 2% to 5% of the loan amount — on a $350,000 loan, that is $7,000 to $17,500 — and cover the appraisal, title search, title insurance, origination fees and prepaid items like a few months of tax and insurance held in escrow.

Review your Closing Disclosure carefully at least three business days before closing. It itemizes every cost, and federal law gives you that window to catch errors. If the numbers do not match your Loan Estimate, ask why before you sign.

After the keys are in your hand, two more budgets begin. Set aside about 1% of the home value per year for maintenance — $3,500 a year on a $350,000 home — because roofs, HVAC systems and water heaters all fail on their own schedule. And expect your property tax and insurance to rise over time, which means your escrow payment, and your total monthly cost, will climb a little every year.

The mistakes that cost buyers the most

Most buyer mistakes are avoidable with preparation. The biggest is buying at the top of the budget with no cash reserve — one surprise repair then puts the mortgage at risk. The second is changing your credit behavior between pre-approval and closing: opening a new credit card, financing a car or missing a payment can tank your loan approval at the last minute. The third is skipping the inspection, and the fourth is not shopping for a lender, which we address next.

Frequently asked questions

How much do I need for a down payment in 2026?

Conventional loans start at 3%, FHA at 3.5%, and VA or USDA at 0%. Twenty percent removes mortgage insurance but is not required. Most first-time buyers put down between 3% and 10%.

How long does buying a home take?

From offer to closing typically takes 30 to 45 days. The pre-approval, saving and credit work before you make an offer often takes several months.

What credit score do I need to buy a house?

You can qualify for an FHA loan with a 580 score, but 760 or higher gets the best conventional rates. Most successful buyers have scores in the 700s. See our credit guide for the full picture.

Should I buy or keep renting?

If you have stable income, a down payment and plan to stay five or more years, buying usually wins. If your timeline is shorter, the closing costs and transaction friction make renting the safer bet.
