Buying a house follows a predictable sequence: confirm you are financially ready, set a budget, choose the kind of loan you need, get pre-approved, hire an agent, make an offer, finalize the mortgage, protect the purchase with insurance, an inspection and an appraisal, renegotiate if needed, and close. The steps overlap in practice. You might talk to lenders while you are still browsing listings, for example. Each step depends on the one before it, though, and skipping one (especially the budget or the inspection) is where most expensive surprises come from.

1. Make Sure You Are Ready

A home is a long-term commitment with high transaction costs, so the first question is whether your finances can carry it. List your monthly income, fixed expenses, debts and savings. Lenders look closely at income stability: a steady employment history, typically measured over the past two years, makes approval easier, while a recent job change or irregular self-employment income can mean more documentation.

Next, check your credit. Most credit scores run from 300 to 850, and the score affects both whether you are approved and the interest rate you are offered. Many conventional lenders set a minimum around 620, and higher scores generally earn better pricing. You can pull your credit reports for free through AnnualCreditReport.com, the federally authorized source, and review them for errors such as accounts you do not recognize or late payments that were reported incorrectly. Disputing a mistake before you apply is much easier than explaining it during underwriting.

Readiness is also about the rest of your financial plan. If a down payment would drain your emergency fund or stop your retirement contributions, buying now may cost more than it appears to. Consider how long you expect to stay. Buying and selling both involve closing costs and commissions, so a home you sell after a year or two can easily lose money even if prices hold steady.

Tip: Avoid opening new credit cards, financing a car or making large unexplained deposits in the months before you apply, and keep your finances unchanged until closing. Lenders review recent activity and often re-check credit and employment shortly before closing, so new debt or a job change can delay or derail approval.

2. Set a Budget

Start from the monthly payment you can comfortably afford, then work backward to a price. Lenders describe the core housing payment as PITI:

• Principal: the portion that repays the loan balance
• Interest: the lender’s charge for the loan
• Taxes: property taxes, usually collected monthly into an escrow account
• Insurance: homeowners insurance, also usually paid through escrow

Two more items often sit on top. If you put less than 20% down on a conventional loan, you will usually pay private mortgage insurance (PMI). If the home is in a community with a homeowners association, HOA dues add to your monthly housing cost even though they are paid to the association rather than the lender.

How lenders measure affordability

Lenders compare your debts to your gross (pre-tax) monthly income. This is your debt-to-income ratio, or DTI. A long-standing guideline is the 28/36 rule: housing costs at or below about 28% of gross monthly income, and total debt payments (housing plus car loans, student loans, credit card minimums) at or below about 36%. Individual loan programs allow higher ratios, but the guideline is a useful ceiling for your own planning, because the maximum a lender approves is not necessarily what fits your budget.

Hypothetical example: A household earns $8,000 a month before taxes.

• 28% of $8,000 = $2,240 for the full housing payment
• 36% of $8,000 = $2,880 for all monthly debt payments
• If the household already pays $500 a month on a car loan and student loans, the total-debt limit leaves $2,380 for housing, so the 28% figure ($2,240) is the tighter limit.

Turning a payment into a price

The principal and interest portion of a fixed-rate mortgage follows a standard formula:

M = P × [r(1 + r)^n] / [(1 + r)^n − 1]

where P is the loan amount, r is the monthly interest rate (annual rate divided by 12) and n is the number of monthly payments.

Hypothetical example (assumptions: $300,000 price, 10% down, 30-year fixed loan, 6% annual rate): The loan amount is $270,000, r is 0.005 and n is 360. Principal and interest come to about $1,619 a month. Property taxes, insurance and PMI are added on top of that figure, so the full payment would be noticeably higher. Run the same math at your own price and a rate a lender actually quotes you. Because interest is charged on the remaining balance, early payments are mostly interest.

Upfront cash

The down payment is only part of the cash you need. Lenders commonly accept down payments anywhere from 3% to 20% of the price depending on the loan, and some government-backed loans require nothing down. On top of that, budget for:

• Earnest money, a good-faith deposit submitted with your offer and credited toward your costs at closing
• Closing costs, such as lender fees, title insurance, appraisal and recording fees, and prepaid taxes and insurance
• Inspection fees
• Moving costs and immediate repairs or furnishings

Keep reserves after closing as well. Lenders sometimes require a few months of payments in reserve, and a new owner’s first unexpected repair rarely waits.

3. Find the Right Property

With a budget set, define what you are shopping for. Location usually matters most because you cannot change it later: commute times, school districts, access to stores and services, and neighborhood safety all affect daily life and resale value. Look into planned development nearby, flood zones and property tax rates, which can differ between neighboring towns.

Then separate needs, such as minimum bedrooms and bathrooms, accessibility requirements, a maximum commute or a particular school district, from wants like a finished basement, a larger yard, an updated kitchen or a garage.

Each home type carries different obligations. A condo or townhouse usually comes with HOA dues and rules but less exterior maintenance, while a single-family house gives more control and more responsibility.

Homes that need work often list for less. If you are open to a fixer-upper, be honest about how much time, skill and money you can put into improvements. Renovation costs tend to run over estimates, and some repairs (roofs, foundations, electrical systems) are not do-it-yourself projects.

4. Shop for Financing Options

The loan type affects your down payment, your credit requirements, whether you pay mortgage insurance and which properties qualify. The main options:

• Conventional loans: Offered by banks, credit unions and other private lenders and not insured by a government agency. They generally require good credit. A 20% down payment avoids PMI, but many conventional programs accept far less, with PMI added. PMI on a conventional loan can be cancelled once you build enough equity, under the rules of the federal Homeowners Protection Act.
• FHA loans: Insured by the Federal Housing Administration and available only for a primary residence. Borrowers with a credit score of 580 or higher can put down as little as 3.5%; scores from 500 to 579 require at least 10% down. FHA loans charge their own mortgage insurance premium (MIP), both upfront and annually, rather than PMI, and the premium does not drop off the way conventional PMI can on many loans.
• VA loans: Guaranteed by the U.S. Department of Veterans Affairs for eligible service members, veterans and certain surviving spouses. They allow 0% down and do not require monthly mortgage insurance, though most borrowers pay a one-time VA funding fee.
• USDA loans: Backed by the U.S. Department of Agriculture for eligible rural and some suburban areas, with income limits. They also allow no down payment.
• Jumbo loans: Used when the loan amount exceeds the conforming loan limits set each year by the Federal Housing Finance Agency. They usually require strong credit, a larger down payment and more cash reserves, and they are most common in high-cost areas.
• Renovation loans: Combine the purchase price and renovation costs in one mortgage. The FHA 203(k) program is the government version; conventional renovation loans exist for well-qualified borrowers. Renovation loans typically cost somewhat more than the comparable standard loan because the lender takes on construction risk.

You also choose a term and rate structure. A 30-year fixed-rate loan gives the lowest fixed payment; a 15-year fixed has higher payments but far less total interest. An adjustable-rate mortgage (ARM) starts with a fixed rate for a set period and then adjusts, which can suit buyers who expect to sell or refinance before the adjustment.

Many state and local housing agencies run down payment and closing cost assistance programs for first-time buyers, often defined as anyone who has not owned a home in the past three years. Ask lenders which programs they work with.

5. Get Pre-Approved

A pre-approval is a lender’s conditional statement that it would lend you up to a certain amount, based on a review of your finances. It does three things: it tells you which price range is realistic, it shows sellers you are a credible buyer, and it surfaces credit or income problems while you still have time to fix them. In a competitive market, an offer without a pre-approval letter may be passed over.

Don’t confuse pre-approval with prequalification. Prequalification is usually an estimate based on information you report yourself. Pre-approval involves documentation and a credit check. Expect the lender to ask for:

• Recent pay stubs and W-2s
• Federal tax returns, typically for the past two years
• Bank and investment account statements
• Proof of identity and employment verification
• Information on existing debts

The credit check is a hard inquiry. It stays on your credit report for two years but typically affects scores only for the first year, and the effect is usually small. Credit scoring models treat multiple mortgage inquiries within a short window as a single inquiry for scoring purposes (14 to 45 days, depending on the model), so you can compare several lenders without multiplying the damage.

Pre-approval letters commonly remain valid for 60 to 90 days. Get one when you are ready to shop seriously; if your search runs longer, the lender can update it with fresh documents.

6. Find a Real Estate Agent

A buyer’s agent finds listings, arranges showings, prepares a comparative market analysis, writes and negotiates your offer, and coordinates with the lender, inspector, appraiser and title company through closing. You are not legally required to use one, but for a first purchase the agent’s knowledge of local pricing, contracts and deadlines carries real weight.

Choose for local market knowledge, experience with buyers in your price range, and responsiveness. Ask friends and colleagues for referrals, read reviews and interview two or three candidates. Useful questions include how many buyers they represented in the past year, how they handle multiple-offer situations, and how often they will check in.

Be clear about compensation from the start. Following the 2024 settlement involving the National Association of Realtors, buyers working with an agent who is a Realtor generally sign a written buyer representation agreement before touring homes. The agreement must state the agent’s compensation, which is negotiable. That compensation can be paid by you, by the seller as part of the deal, or through a combination negotiated in the purchase contract. Read the agreement’s length, termination terms and fee before you sign.

7. Go House Hunting and Make an Offer

Searching can take a few weeks or several months depending on inventory and competition. Tour more homes than you think you need, so you understand what your budget actually buys. During showings, look past staging and paint at the things that are expensive to fix: the roof, foundation, windows, water stains, the age of the furnace and water heater, and how the lot drains.

When you find the right home, your agent will prepare a comparative market analysis (CMA), which estimates a fair price from recent sales of similar nearby properties. The offer itself is more than a price. A typical purchase offer includes:

• Price and the amount of earnest money
• Financing terms, including loan type and down payment
• Proposed closing date
• Contingencies that let you exit or renegotiate without losing your deposit if certain conditions are not met
• Any items included in the sale (appliances, fixtures) and requested seller concessions, such as help with closing costs

The three standard contingencies:

• Inspection contingency: lets you inspect the home within a set number of days and renegotiate or withdraw based on the findings
• Appraisal contingency: protects you if the home appraises below the contract price
• Financing contingency: protects you if your mortgage approval falls through before closing

Waiving contingencies can make an offer more attractive to a seller, but it shifts risk to you. If you waive the appraisal contingency and the home appraises low, for example, you may have to cover the gap in cash or forfeit your earnest money.

Expect back-and-forth. The seller may accept, reject or counter, and several rounds of counteroffers are normal. In multiple-offer situations you can lose a home to a stronger bid; set your walk-away price before negotiations begin so competition does not push you past your budget.

8. Get Your Mortgage

Once your offer is accepted, apply formally for the loan. A pre-approval is not binding on you, so this is a good point to compare lenders. Within three business days of receiving your application, each lender must give you a Loan Estimate, a standardized federal form that lists the rate, monthly payment and closing costs. Because the format is identical across lenders, you can line up offers side by side, comparing the APR, origination charges and points, not only the interest rate.

When you have chosen a lender, you will typically lock your interest rate for a set period, ideally long enough to reach closing. You will then resubmit or update your documents: W-2s, tax returns, pay stubs, bank statements, proof of assets for the down payment and closing costs, and ID. Large deposits may need a paper trail; gift funds from family usually require a signed gift letter.

The file then moves to underwriting, where the lender verifies your income, assets, credit and the property itself. Underwriters often ask for additional documents or explanations, and responding quickly keeps the closing date on track. Approval may arrive with conditions that must be cleared before the lender issues final approval, often called “clear to close.” The whole process can take as little as two weeks or as long as two months.

9. Get Homeowners Insurance, a Home Inspection, and a Home Appraisal

Between the accepted offer and closing, three safeguards protect both you and the lender.

Homeowners Insurance

Lenders require proof of homeowners insurance before closing. A standard policy covers the structure and your belongings against perils such as fire and windstorms, and includes liability coverage if someone is injured on the property. Standard policies generally exclude flood and earthquake damage, which require separate coverage; if the home is in a designated high-risk flood zone and has a federally backed mortgage, flood insurance is required. You choose the insurer, but the policy must meet the lender’s minimum coverage. Get quotes from several companies, and ask about deductibles and whether the policy pays replacement cost or actual cash value.

Home Inspection

An inspection is not legally required, and it commonly costs a few hundred dollars (often cited at roughly $300 to $500, varying by home size and region). A licensed inspector examines the structure, roof, electrical system, plumbing, HVAC, attic, foundation and visible signs of water damage or pests, then delivers a written report. Attend the inspection if you can; seeing problems in person makes the report easier to interpret.

General inspectors do not cover everything. If the report or the house raises specific concerns, such as foundation cracks, sloping floors, water stains, musty odors, signs of pests or unpermitted wiring, hire a specialist: a structural engineer, a sewer scope for older drain lines, or radon, mold, termite or asbestos testing where relevant.

Home Appraisal

The appraisal estimates the home’s fair market value based on its condition, location and recent comparable sales. The lender orders it through an independent licensed appraiser, and you usually pay the fee. The lender relies on the appraisal because it will not lend more than the property supports.

If the appraisal comes in at or above the contract price, the deal proceeds. If it comes in below the price, the lender bases the loan on the lower value, leaving a gap. You can ask the seller to reduce the price, pay the difference in cash, split the difference, challenge the appraisal with better comparables, or, if you have an appraisal contingency, cancel the contract and recover your earnest money.

10. Renegotiate With the Seller

The inspection and appraisal results often reopen negotiations. You might ask the seller to make repairs before closing, give a credit toward your closing costs, or lower the price. Your leverage depends on the market: sellers are more likely to agree in a buyer’s market and may refuse in a seller’s market when other buyers are interested.

To negotiate effectively:

• Prioritize safety, structural and major-system issues over cosmetic ones
• Get written repair estimates from contractors to support your request
• Consider a credit instead of seller-performed repairs, so you control the quality of the work
• Let minor items go where needed and keep communication professional

If you cannot reach an agreement and your contingency period is still open, you can typically walk away with your deposit. Watch the deadlines in your contract closely, because contingencies expire on specific dates.

11. Close the Deal

At least three business days before closing, your lender must provide a Closing Disclosure, the final version of your loan terms and costs. Compare it line by line with your Loan Estimate and ask about any changes. The closing costs listed may include:

• Loan origination fees and any discount points
• Appraisal and credit report fees
• Title search and title insurance
• Home inspection fees, if not paid earlier
• Attorney or settlement agent fees, where applicable
• Government recording fees and transfer taxes
• Prepaid property taxes, homeowners insurance and interest, plus initial escrow deposits

Before closing, the title company searches public records to confirm the seller can transfer clear ownership and that there are no unpaid liens. Lender’s title insurance is generally required; owner’s title insurance, which protects you, is usually optional but worth considering.

Shortly before closing, do a final walk-through to confirm the home is in the agreed condition, repairs are complete and included items are still there. Arrange your funds in advance: closing funds are usually sent by wire transfer or cashier’s check. Wire fraud targeting homebuyers is a known risk, so confirm wiring instructions by calling your title or escrow company at a number you have verified independently, not one from an email.

At closing you sign the promissory note, the mortgage or deed of trust, and related documents. Some closing costs can be covered by seller credits or, in certain cases, financed into the loan. Once the documents are signed, funds are disbursed and the deed is recorded, the home is yours.

Ongoing Expenses of Homeownership

Your monthly mortgage payment is the most predictable cost of owning a home, not the only one. Plan for:

• Property taxes: Set by local governments as a percentage of assessed value. They vary widely by location and can rise after reassessments.
• Homeowners insurance: Premiums can increase at renewal. If you pay through escrow, higher taxes or premiums raise your monthly payment even on a fixed-rate loan.
• HOA dues: From about $50 to more than $1,000 a month, plus possible special assessments for major projects.
• Maintenance and repairs: A common rule of thumb is to set aside about 1% of the home’s value each year, more for older homes.
• Unexpected costs: Storm damage beyond your deductible, burst pipes or system failures that insurance does not cover.

The Bottom Line

Anyone planning a first home purchase benefits from following the steps in order, starting with credit, savings and a realistic monthly budget. Get pre-approved, compare Loan Estimates across lenders, and keep inspection, appraisal and financing contingencies unless you can absorb the risk. Plan for property taxes, insurance and roughly 1% of the home's value each year in maintenance after closing.
