How a Home Inspection Actually Works: The Buyer's Process, Start to Finish

How a home inspection works, in six steps

The home-inspection process is one long step-down from "an offer was accepted" to "you closed on the house." Each step has a clear job for the inspector or your agent, a clear job for you, and one decision you make before moving on:

1. Book — choose and schedule the inspector. Decision: which inspector to hire.
2. Prep — collect disclosures, write down concerns. Decision: what to ask the seller for in advance.
3. Walkthrough — 2 to 4 hours on site. Decision: whether to attend, and in what mode.
4. Report — typically delivered within 1 to 2 business days. Decision: how to triage the findings.
5. Respond — send your repair-or-credit ask to the seller. Decision: repair, credit, or walk.
6. Close — optional re-inspection, then closing. Decision: re-inspect or trust the seller's word.

The whole sequence usually fits inside the 5-to-10-day inspection contingency window in your purchase agreement. The pacing matters more than buyers expect.

Step 1: Book the inspection

Booking starts within hours of your offer being accepted. The contingency clock starts at acceptance, not at the inspection, so a day spent shopping for inspectors is a day off the back end of your negotiation window.

You'll get inspector names from your agent, an online search, or someone who's bought recently. Agent referrals are convenient but carry a soft conflict — an inspector who flags too much can get dropped from the referral list. Ask for at least two names and look at each one's sample report yourself.

What to look for: state license (where required), current insurance, ASHI or InterNACHI certification, a sample report on the website, and reviews that describe what the inspector caught. Cost runs in the mid-to-high hundreds for a typical single-family home; add-ons (sewer scope, radon, mold sampling, drone roof imaging) are each a separate fee.

The one decision at this step: which inspector to hire. A weak inspector misses things you'll discover after closing. A thorough inspector gives you the leverage you'll spend in step 5. The price gap between the cheapest and the middle tier is often a hundred or two; the gap in what they find can be a four-figure swing in your negotiation.

Step 2: Prep for inspection day

The 24 to 48 hours between booking and inspection day are where most buyers go quiet, assuming there's nothing to do. Prep is short, but it sets up everything that follows.

Read the seller's disclosure statement before the inspection. It's the list of things the seller is on record acknowledging — past leaks, repairs, replacements, known defects. You want to compare what the seller disclosed to what the inspector finds. An inspector flagging something the seller didn't disclose is a different conversation than a routine finding.

Write down your specific concerns. If the listing mentioned a new roof, you want to confirm the roof was replaced, not patched. If a relative who walked through noticed a crack in the basement or a soft spot in the floor, write it down so the inspector can look closely.

The one decision at this step: what to ask the seller for before the inspection starts. A buyer who walks in cold misses things. A buyer who walks in with a written list of concerns and disclosures in hand gets a more focused walkthrough and a more useful report.

Step 3: Walk through the inspection

A typical inspection takes 2 to 4 hours; older or larger homes can run longer. You don't have to be there the whole time, and some inspectors prefer that you join only for the last hour so they can give you a cleaner summary. Attending in some form — in person or by phone — is one of the higher-leverage things a buyer does.

What you'll see: the inspector walks the roof (or photographs it from a drone), opens the electrical panel, runs the HVAC, tests every plumbing fixture, checks for moisture in the basement or crawlspace, and photographs every finding. They work from a standard systems-by-systems checklist. Scope-of-practice rules vary by state, but the basic approach is consistent.

What you're doing: listening, taking notes, and asking "how should I fix that?" at each flagged item. Your job is to understand which findings are routine, which are bigger, and which ones the inspector is using a flat tone to say something serious about. The phrase "I'd recommend a qualified specialist evaluate this" is the inspector's way of saying "I see something I can't fully scope from up here."

If you're buying remotely: ask the inspector before the day whether they offer a video walkthrough. Most do now. A typical setup is your agent or a paid local representative attends in person, the inspector ends the visit with a 20-to-30-minute video call summarizing the findings, and the photo-rich report follows within a business day. It's a different experience, not a worse one.

The one decision at this step: whether to attend, and in what mode — in person the whole time, in person for the last hour, or remote video. Inspector preferences vary; ask before the day.

For what the inspector is checking (and what's outside scope), see what home inspectors actually check.

Step 4: Read the report

Most inspectors deliver the report by the end of the next business day; some same-day. The report is typically 30 to 60 pages, organized by system, with photos for each finding. The first read is the one that knocks anxious buyers sideways — every house, even a new one, generates a long list of findings, and the report rarely tells you which ones matter.

A useful frame: most items in a typical report are routine homeowner-maintenance notes the inspector documents because that's their job. A smaller share, usually 10 to 30 percent, is what your negotiation will be about. Your task on the first read is to separate the two.

Read it once front to back. On a second pass, highlight every item where the inspector recommended a specialist — those have the most open-ended cost — and look for cumulative patterns at the same time: three drainage findings together can add up to a bigger problem than any one alone, and the inspector won't always connect them explicitly.

The first read is not the time to draft a repair list. Give yourself an afternoon before responding.

The one decision at this step: how to triage the findings — which items are potential deal-breakers, which need specialist quotes before you can decide, and which are routine. The inspector usually won't make that call for you, and they're not supposed to.

Step 5: Respond to the seller

Once you've triaged the report, your agent sends a written response to the seller's side. The formal name varies — repair request, inspection objection notice, inspection response form — but the function is the same. The seller can accept, counter, or refuse; you can then accept their response, counter again, or use the contingency to walk.

The classic structure of the ask is a short list of items you're requesting either a repair on or a credit for. Most buyers don't ask for the whole report. They ask for items that are safety-related (electrical hazards, gas leaks, structural movement, active water intrusion) or expensive enough that the cost would be noticed (roof replacement, HVAC at end of life, sewer-line replacement). Routine maintenance items go on your own first-year list.

The repair-vs-credit choice matters more than buyers think. A seller-managed repair gets done by a contractor the seller chooses, often on a tight deadline. A credit lets you choose your own contractor after closing. Sellers often prefer credits (no liability for repair quality). Lender rules can constrain credits, especially on FHA or VA loans, so check with your loan officer before asking for a large one.

If you and the seller can't agree before your contingency expires, you can usually request a written extension.

The one decision at this step: repair, credit, walk, or extend. The right answer depends on the cost of the items, the seller's willingness, the local market, and how attached you are to this specific house.

For deeper guidance on the response, see what happens after a home inspection.

Step 6: Re-inspect (maybe) and close

If the seller agrees to fix items, you can schedule a re-inspection before closing to confirm the work was done and done correctly. A re-inspection is usually a flat fee for the inspector to come back and check the specific items they flagged — a fraction of the original cost.

Skipping it means trusting that the repairs were done correctly. For low-stakes items (a loose railing, a missing GFCI outlet) that's usually fine. For higher-stakes items (a roof patch, an electrical-panel repair, a water-heater replacement), a re-inspection is cheap insurance against showing up at closing with surprises.

Then the loan moves through final underwriting, the appraisal is confirmed, the title is cleared, and you walk through the home one more time on closing day to confirm nothing has changed since the inspection.

The one decision at this step: whether to re-inspect the seller's repairs before closing. Worth it for high-stakes items; optional for low-stakes ones.

How the contingency clock spends down

Most purchase agreements give the buyer a 5-to-10-day inspection contingency window from offer acceptance. Some markets give longer; Texas-style "option periods" let the buyer extend by paying option fees. Confirm the exact window with your agent at the start, then plan the steps against it. Roughly how the days spend down in a 10-day window:

• Days 1–2: book the inspector, request seller disclosures, write your concerns list.
• Day 3: inspection day.
• Days 4–5: report delivery and your triage reads.
• Days 4–7: specialist quotes if you need them.
• Days 5–8: send your ask to the seller and negotiate the response.
• Days 8–10: accept, walk, or request an extension.

Pacing breaks down most often at two points: buyers who wait too long to book (losing days 1 and 2 before the inspection happens) and buyers who line up specialist quotes in series instead of in parallel. If a finding looks like it needs a specialist, call the specialist the same day you read the report. The contingency window doesn't pause for scheduling.

Common mistakes that cost buyers leverage

A handful of the same mistakes show up across most inspection cycles.

Skipping the walkthrough. Even partial attendance gives you a calibration for the inspector's tone you can't get from the report alone. Skipping it makes the report harder to read.

Treating the report as the inspector's recommendation. The report documents findings. It doesn't tell you which ones to negotiate, accept, or walk for. That's your call. A buyer who treats the report as a list of demands gets pushback on every item; a buyer who treats it as a triage source asks for fewer things and gets more of them.

Asking for everything. A seller treats a list of forty repair requests the way you'd treat a stranger asking for forty favors. Ask for items that are safety-related or expensive enough that the cost would be noticed. Note the rest for your first-year maintenance list.

Lining up specialist quotes in series. If two findings need specialist evaluation, call both specialists the same morning. You want to learn the lead times on day 5, not day 9.

What to do once you have the report

You'll walk away from the walkthrough with a few flagged items in mind, and 24 to 48 hours later the report will land in your inbox with every finding written down. The fastest way to lose leverage in your contingency window is to read the report once, panic, and either ask for everything or ask for nothing.

InspectionTriage reads your report, separates routine maintenance items from negotiation-worthy ones, gives you cost context for the bigger findings, and produces a prioritized list you can send to your agent the same day. It's built for the buyer who has a real report and a real deadline. See what's worth negotiating — free
