How the Home Buying Process Works

You’ve done the affordability math. You know roughly what you can spend. What you probably don’t have is a clear picture of what the next three to six months actually look like, who the players are, what you sign, where deals fall apart, and what you’re supposed to do at each stage.

Here is the map.

The Players: Who Is Involved and What They Do

Before anything else, understand who’s in the room and whose interests they actually represent.

Buyer’s agent: Represents you in the transaction, helps you find homes, submit offers, and negotiate. In most transactions, the buyer doesn’t pay the agent directly. The commission is paid by the seller out of the sale proceeds. That sounds great, but remember: your agent only gets paid when a deal closes. A good agent will steer you toward the right home. A mediocre one will steer you toward closing. Know the difference.

Seller’s agent (listing agent): Represents the seller. They’re friendly and helpful, but they’re not on your side. Don’t share anything with them that you wouldn’t want the seller to know, like how much you’re really willing to pay or how desperate you are to find a place.

Mortgage lender / loan officer: The person you apply with, who structures your loan and guides you through the process. They work for the bank or mortgage company. Their job is to get your loan approved and closed.

Underwriter: The person at the lending institution who actually makes the decision to approve or deny your loan. You’ll probably never speak to them directly, but they control everything. When a lender asks for more documents or explains why the loan is delayed, it is almost always because the underwriter asked for something.

Home inspector: Hired by you. Examines the physical condition of the property and produces a written report. Not a pass/fail test, just a detailed list of what they found.

Appraiser: Hired by the lender (and paid for by you, usually added to closing costs). Values the property independently to make sure the lender isn’t loaning more than the home is worth. You don’t choose the appraiser and don’t interact with them.

Title company / closing attorney: Depending on your state, either a title company or a real estate attorney handles the closing. They verify that the seller actually owns the property free and clear, prepare the closing documents, and facilitate the transfer. In attorney states (roughly the northeast and southeast), an attorney is required at closing.

Escrow officer: Holds the funds during the transaction, your earnest money deposit, then eventually all closing funds, and disburses them at closing. This is often part of the title company’s function.

Step 1: Get Pre-Approved (Not Pre-Qualified)

Pre-qualification is a conversation. You tell the lender your income, assets, and debts, and they give you a rough number. No documents checked. No credit pull. Sellers know this, and in any competitive market, a pre-qualification letter is essentially worthless.

Pre-approval is different. You submit actual documentation, pay stubs, W-2s, tax returns, bank statements, and the lender pulls your credit. They verify what you told them and issue a letter stating they’re conditionally willing to lend you up to a specific amount. That letter is what sellers want to see with an offer.

What lenders check during pre-approval:

Credit score: Minimum 620 for most conventional loans, 580 for FHA. But the best interest rates start around 740. A 0.5% rate difference on a $350,000 loan is roughly $90 per month, over $30,000 over 30 years.
Debt-to-income ratio (DTI): All monthly debt payments (car, student loans, credit card minimums) divided by gross monthly income. Most conventional lenders want this below 43%, with better outcomes below 36%.
Employment history: Typically two years of stable employment in the same field. Recent job changes aren’t automatic disqualifiers but require explanation.
Assets: Your savings, checking, investment accounts, proof you have the down payment and reserves. If any of your down payment is a gift from family, there are specific rules. You’ll need a gift letter stating the funds are not a loan, and the lender will trace where the money came from.

One useful warning: The amount you’re approved for is the maximum the lender will give you, not a recommendation. Lenders approve based on the outer limits of your financial picture. What’s comfortable is usually $50,000–$150,000 less than your approval limit, depending on your situation. Run your own math on the all-in monthly cost, mortgage payment plus property taxes, insurance, and PMI, before deciding what price range to search in.

Shopping multiple lenders: Apply with two or three lenders within a 14-day window (the major credit bureaus give you 45 days for mortgage rate shopping, but the older FICO models use 14). All the mortgage credit pulls within that window count as a single inquiry on your credit. There’s no penalty for comparing. The Loan Estimate each lender provides within three business days of your application uses a standardized format. Compare them side by side.

The pre-approval letter states the lender’s conditional willingness to lend up to a specific amount. Sellers require this with offers. Some listing agents will call the lender directly to verify it.

Step 2: Find a Home and Make an Offer

When you find a home you want, your agent prepares a purchase offer, a formal contract that includes the price, terms, contingencies, and your earnest money deposit.

Earnest money deposit: This is “good faith” money you put up to show you’re serious. Typically 1–3% of the purchase price, paid within a few days of an accepted offer. On a $400,000 home, that is $4,000–$12,000. It goes into escrow and is applied toward your down payment or closing costs at closing. If you back out for a reason covered by a contingency (more on those below), you get it back. If you back out without a valid contingency reason, you lose it.

Contingencies are your exits. They’re clauses in the contract that give you the right to cancel and get your earnest money back under specific circumstances:

Inspection contingency: You have the right to have the home inspected and to cancel the contract if the results are unacceptable to you. This is the most common contingency.
Financing contingency: If your loan falls through despite good-faith effort, you can exit without losing your deposit. Never waive this unless you’re buying with cash or have ironclad alternative financing.
Appraisal contingency: If the home appraises below the purchase price, you have the right to renegotiate or walk. Without this contingency, you’re obligated to either cover the difference in cash or find another way to make the deal work.

Waiving contingencies: In highly competitive markets, buyers sometimes waive contingencies to make their offer more attractive. That is real risk, not just paperwork. Waiving the inspection contingency means if you close and then discover a $30,000 problem, the cost is on you. Waiving the financing contingency means if your loan falls through, you can lose your earnest money. Only do this with a clear understanding of what you’re giving up.

Escalation clauses: In competitive markets, you can include an escalation clause that automatically increases your offer above any competing offers up to a ceiling you set. For example: “Offer is $420,000, with an escalation of $2,000 above any bona fide competing offer, up to a maximum of $445,000.” Your agent can walk you through when this makes sense.

After you submit an offer, the seller accepts, counters, or rejects. Counteroffers are common, price, closing date, what stays with the home, seller concessions. This back and forth is normal. Once both parties agree and sign, you’re under contract (also called going into escrow).

Step 3: The Inspection

Once you’re under contract, the clock starts. You typically have 10–14 days to complete your inspection, check your contract for the exact window.

Who pays: You do. A general home inspection runs $300–$600, depending on the size of the home and your market. You pay the inspector directly at the time of inspection.

What it covers: A licensed inspector does a visual examination of the accessible systems and components of the home, roof, foundation, electrical, plumbing, HVAC, walls, ceilings, windows, doors, attic, and crawl space. They’re not allowed inside walls. They’re not always able to access a roof that’s too steep or icy. They note what they see, not what might be hiding.

What inspectors commonly find: Old or end-of-life HVAC systems, outdated electrical panels (knob-and-tube wiring, Federal Pacific panels that are known fire hazards), roof wear or damage, evidence of water intrusion, foundation cracks, missing or improper permits for additions, and deferred maintenance of all kinds.

Specialist inspections you might add:

Sewer scope: A camera run through the sewer line to check for root intrusion, cracks, or blockages. $150–$300. Worth it on any home over 20 years old.
Radon test: Radon is a colorless, odorless radioactive gas that seeps from the ground and accumulates in basements. High levels are a real health risk. Testing kits or inspector add-ons cost $25–$150. Mitigation systems (if needed) cost $800–$2,500.
Mold / air quality testing: Add if the inspector notes water intrusion, musty odors, or visible discoloration.
Structural engineer: If the inspector flags foundation concerns or structural issues, a structural engineer’s assessment ($300–$700) gives you more specific answers before you decide what to do.

After the inspection report: You have three main options, accept the home as-is, request repairs or a price reduction / closing cost credit, or cancel the contract and get your earnest money back (if you have the contingency). Most buyers ask for some repairs or credits. Most sellers respond. This is a negotiation, not a demand.

The inspection is not a pass/fail test. Every home has issues. A 10-year-old house will have a 10-year-old roof, GFCI outlets that need updating, and caulk that needs redoing. The question is which findings are material, meaning they affect safety, habitability, or will cost significant money to address. Focus there. Don’t use the inspection report to renegotiate a deal over cosmetic things you already knew about.

Step 4: The Appraisal

After the inspection negotiation wraps up, the lender orders the appraisal. You pay for it, typically $400–$700, rolled into closing costs, but you don’t choose the appraiser and don’t interact with them directly.

The purpose: The lender won’t give you a mortgage for more than the home is worth. Their security for the loan is the property itself. If you stopped paying, they want to be able to sell the home and recover what they lent. The appraisal is how they verify value.

What appraisers look at: Comparable recent sales (comps) in the neighborhood, the home’s condition, square footage, lot size, location, upgrades, and number of bedrooms and bathrooms. The appraiser synthesizes all of this into a market value estimate.

If the appraisal comes in below purchase price: This is called an appraisal gap. Say you offered $420,000 and the home appraises at $400,000. The lender will only fund based on $400,000 value. You have a few options:

Renegotiate the price down to the appraised value (sellers don’t always agree)
Cover the gap in cash, you bring an extra $20,000 to closing to make up the difference
Walk away if you have an appraisal contingency

Hot markets and appraisal gaps: During rapid price appreciation, appraisals can lag because comps reflect sales from 60–90 days ago, not today’s prices. Appraisal gaps were extremely common during 2020–2022. If you’re in a competitive market with rising prices, think through what you’d do if this happens before you make an offer.

Step 5: Underwriting, the Most Opaque Part

After the inspection and appraisal are handled, your loan file goes to underwriting. This is the opaque part where the bank’s underwriter reviews everything and decides whether to approve your loan.

What they’re checking: Everything in your pre-approval file, again, plus the specific property. They’re confirming that your financial picture hasn’t changed since pre-approval and that the property itself meets their requirements.

Why they ask for more documents: Underwriters follow the money. If your bank statement shows a deposit of $8,000 and no explanation, they want to know where it came from. If you switched jobs since pre-approval, they want to verify the new income. If your credit card balances went up since the initial credit pull, they want to understand it. Every question feels annoying but has a purpose.

What not to do during underwriting:

Do not open new credit cards
Do not finance a car or any large purchase
Do not quit or change your job (talk to your lender first if this is unavoidable)
Do not move large sums of money between accounts without keeping documentation
Do not co-sign any loans

Any change that increases your debt, reduces your income, or changes your credit profile can affect your loan approval, even after pre-approval.

Conditions: Underwriters rarely approve a loan with zero conditions. “Approved with conditions” is the normal outcome. The underwriter lists specific things they need before issuing a “clear to close.” Common conditions: provide a letter explaining that large deposit, provide a current pay stub, provide proof that the earnest money cleared, verify that you paid off a certain debt.

Your loan officer collects the conditions and resubmits. Once all conditions are met, you get the clear to close.

Timeline: Underwriting typically takes 2–6 weeks. In busy markets or if conditions keep coming back, it can take longer. Your purchase contract specifies a closing date, if underwriting is delayed, you may need to request an extension, which requires the seller’s agreement.

Common reasons for denial during underwriting:

Job change or loss after pre-approval
Credit score dropped (a new credit inquiry or a missed payment)
Income verification doesn’t match what was stated
Property issues discovered during appraisal
DTI went above threshold due to new debts

Step 6: Title Search and Homeowners Insurance

While underwriting is happening, two other things need to occur.

Title search: The title company or attorney searches public records to verify that the seller actually owns the property and that there are no liens, unpaid property taxes, judgments, or other claims attached to it. You can’t take clear title to a property that has someone else’s valid claim on it. Most of the time the title comes back clean. Occasionally it doesn’t, there might be an old mechanic’s lien from a contractor who was never paid, or a boundary dispute, or an error in a prior deed. The title company works to resolve these, but in rare cases, a title problem can delay or kill a deal.

Title insurance: There are two types, and they protect different parties:

Lender’s title insurance: Required. Protects the lender if a title defect is discovered after closing. You pay for this at closing.
Owner’s title insurance: Optional, but get it. Protects you if something surfaces after closing, a forgery in the chain of title, an heir who was never disclosed, a survey issue. It’s a one-time premium, typically $500–$1,500, and it covers you for as long as you own the home. This is not a fee to negotiate away.

Homeowners insurance: Your lender requires proof of a policy before closing. Shop for this now, not two days before closing. Get quotes from at least two or three insurers. The first-year premium is often paid at closing as a prepaid item. You’ll need to provide the lender with a declarations page showing coverage.

Step 7: The Final Walkthrough

Typically 24–48 hours before closing, you do a final walkthrough of the property. This is not a second inspection. You’re checking three specific things:

The property is in the same condition it was when you made the offer, the sellers didn’t remove something they were supposed to leave, or leave the place trashed after moving out
Any repairs that were agreed upon as part of the inspection negotiation were actually completed
The agreed-upon personal property (appliances, light fixtures, window treatments if specified in the contract) is still there

Walk through every room. Run water in every sink and shower. Flush toilets. Turn on every appliance. Check the HVAC. Open windows and doors. Look at anything that was flagged in the inspection. If agreed repairs weren’t done, this is the time to raise it, not after you own the house.

If you find problems at the final walkthrough, you have options: delay closing, hold back funds in escrow pending completion, request a credit, or in serious cases, cancel if the seller is in material breach of the contract.

Step 8: Closing

Closing is where you sign everything and get the keys.

Where it happens: At the title company’s office, the closing attorney’s office, or sometimes remotely via a notary (remote online closing, or RON, is available in many states now).

What you’re signing:

Promissory note: Your legal promise to repay the loan. This is the core loan document.
Deed of trust (or mortgage, depending on state): The document that gives the lender a security interest in the property, meaning if you stop paying, they can foreclose. This gets recorded with the county.
Closing disclosure: You should have received this at least three business days before closing. It itemizes every cost, loan terms, monthly payment, closing costs, and how much cash you need to bring. Read it before closing day, not at the table. Compare it to the Loan Estimate you got at the beginning. Flag any fees that changed beyond the allowed tolerances.
Various transfer and title documents, which the closing agent walks you through

What you’re bringing:

Cash for closing: The remaining down payment plus closing costs, minus any deposits already paid. This must come via cashier’s check or wire transfer, personal checks are not accepted. Confirm the exact amount and wire instructions with your title company at least 24 hours in advance. Wire fraud targeting home buyers is common, always verify wire instructions by phone using a number you found independently, not one from an email.
Government-issued photo ID: Passport, driver’s license.

Closing costs recap: For buyers, total closing costs typically run 2–5% of the loan amount. On a $350,000 loan, that is $7,000–$17,500. Major components include lender origination fees, appraisal (already paid), title search and title insurance, prepaid homeowners insurance premium, property tax escrow setup, prepaid interest from closing date through end of month, and recording fees. See What Are Closing Costs? for a full breakdown of each line item.

Signing takes 1–2 hours. After you sign and funds are disbursed (sometimes same day, sometimes the next business day depending on timing), the deed records with the county and you get the keys.

What Can Derail a Deal, and When

Most deals close. But knowing where they fall apart helps you navigate problems when they come up.

Inspection reveals a major problem: If you have an inspection contingency and the inspection reveals something significant, a failing foundation, major structural damage, a roof that needs immediate replacement, you can negotiate or walk. The question is always: is this priced into the deal or not?

Appraisal gap: Home appraises below purchase price. You need to cover the difference in cash, renegotiate, or exit with your deposit if you have the appraisal contingency.

Loan falls through during underwriting: Your financing contingency protects your earnest money if you acted in good faith and the loan was denied. If you waived the financing contingency, you may lose your deposit.

Title issue: Rare, but it happens. The title company typically works to resolve it. In some cases it takes weeks; in others, the deal can’t close until the issue is cleared legally, which could take months.

Seller backs out: Sellers can back out, but it’s harder for them. The purchase contract generally requires them to return your earnest money and may expose them to damages. Your agent and attorney can advise on remedies if the seller tries to walk without valid reason.

Last-minute credit or income change: Job loss, a missed payment, or a new car loan during underwriting can cause a denial at the worst possible moment. If you waived the financing contingency, you risk losing your earnest money. If you have the contingency and can document you acted in good faith, you should be protected.

The Timeline: What to Expect

Pre-approval: 1–5 business days if you have your documents ready. Gather two years of tax returns, two months of bank statements, and recent pay stubs before you apply.

Finding a home: Weeks to months. In competitive markets, you may lose multiple offers before getting one accepted. Budget emotionally for this.

Offer to closing: Typically 30–45 days. Cash transactions can close faster. VA and FHA loans sometimes take longer due to additional requirements. The closing date is negotiated in the contract, sellers often prefer a date that aligns with their own move.

Total from “I’m ready” to keys: Plan for 3–6 months in a normal market. Longer if you’re in a very competitive area with limited inventory. Shorter if you find something quickly and everything goes smoothly.

The process feels long and opaque until you’ve been through it. Each stage has a logic to it, and the paperwork, while voluminous, is covering specific risks that the parties have agreed to manage. Understanding what each step is doing, and what your rights are at each stage, is what separates buyers who feel in control from buyers who feel like things are happening to them.

Frequently Asked Questions

Q: Do I really need a buyer’s agent? Can I just work with the seller’s agent?

You can, but you’re giving up representation in a transaction where the other party has professional representation. The seller’s agent legally can’t advise you in your best interest. Some buyers navigate this successfully, but for a first-time buyer, having your own agent who’s actually working for you is worth it. Since the commission typically comes from the seller’s proceeds, it usually costs you nothing directly, though ask upfront how your agent is compensated, since the post-NAR settlement landscape is shifting.

Q: Can I back out at any point?

You can always back out, the question is whether you get your earnest money back. Before you submit an offer: yes, no consequences. After you’re under contract: your contingencies determine when you can exit with your deposit. After contingencies are released and you exit without cause: you lose your earnest money and possibly face legal action from the seller.

Q: What if the sellers will not make any repairs after the inspection?

That’s their right. You can accept the home as-is (which you were essentially doing before you knew the inspection results), negotiate a price reduction or closing cost credit instead of repairs, or walk if you still have the inspection contingency. Sellers in competitive markets sometimes refuse any concessions and have a backup buyer waiting.

Q: How many homes should I expect to lose before getting one under contract?

In competitive markets, losing two to five offers before landing a home is common. It’s frustrating and demoralizing, but it’s normal. Don’t let repeated losses push you into waiving contingencies you shouldn’t waive or offering more than makes sense. The right home at the right price is a better outcome than any home right now.
