A home inspection is a detailed walk-through of a property by a trained inspector who looks for structural problems, safety hazards, and systems that may fail soon
Before you buy a house, a professional inspector examines the foundation, roof, plumbing, electrical system, HVAC, and interior conditions. They produce a written report listing what works, what needs repair, and what poses a safety risk. This report becomes the basis for negotiating repairs with the seller, deciding whether to walk away, or knowing what to budget for after closing.
A home inspection is not the same as an appraisal (which estimates value for the lender) or a title search (which confirms ownership). It is a separate service you pay for directly, usually $300 to $500 depending on the house size and your location. The inspector has no stake in whether the sale closes, so their job is to tell you the truth about the property's condition.
Key Takeaways
- A home inspection reveals structural damage, failing systems, and safety hazards before you sign the final papers, giving you leverage to negotiate repairs or price reductions.
- Inspectors examine the foundation, roof, plumbing, electrical, HVAC, and interior conditions, then provide a written report you can use to make an informed decision.
- You hire and pay the inspector directly; they work for you, not the seller or lender, so they have no reason to hide problems.
- If the inspection uncovers major issues, you can ask the seller to repair them, lower the price, or walk away without losing your earnest money deposit.
What inspectors actually look for and what they report
A standard home inspection covers the major systems and structural elements. The inspector checks the foundation for cracks, the roof for missing shingles or leaks, the plumbing for corrosion or slow drains, the electrical panel for code violations, and the HVAC system for age and function. They also look at windows, doors, insulation, and interior walls for water damage or settling.
The report lists findings in categories: items that are functioning normally, items that need maintenance soon, items that need repair, and items that pose a safety risk. A roof with 15 years of life left might be listed as "serviceable"; one with visible rot might be flagged as "repair needed." A 40-year-old water heater might be noted as "near end of service life." An electrical panel with exposed wiring gets flagged as a safety hazard.
Inspectors do not test every outlet, run water in every fixture, or move furniture. They do a visual walk-through. They will not find every small problem, but they will catch the ones that matter: foundation issues, roof leaks, mold, outdated wiring, failed HVAC systems, and plumbing that backs up.
How inspection results affect your purchase decision
Once you have the report, you have three paths forward. You can ask the seller to repair the items listed, you can ask for a price reduction to cover repairs you will do yourself, or you can walk away if the problems are too severe or expensive.
Most purchase contracts include an inspection contingency, which means you can cancel the deal and recover your earnest money deposit if the inspection reveals major problems. The exact terms depend on your contract, but typically you have 7 to 10 days to order the inspection and decide whether to proceed. If you find serious issues and the seller will not repair or reduce the price, you can back out without penalty.
In a competitive market, sellers may refuse to make repairs or negotiate. In that case, the inspection report still tells you what to budget for after closing. A roof replacement might cost $8,000 to $15,000; a new HVAC system might cost $5,000 to $10,000. Knowing these costs before you buy lets you decide whether the house is still worth the price.
When to order an inspection and who to hire
Order the inspection as soon as your offer is accepted and the contingency period begins. Do not wait until the last day; inspectors book up, and you need time to review the report and decide your next move. Most inspections take 2 to 4 hours, depending on house size.
Hire an inspector who is licensed in your state. Licensing requirements vary: some states require a formal license and continuing education; others have minimal oversight. Ask your real estate agent for referrals, check online reviews, and confirm the inspector carries errors and omissions insurance. An inspector with 10+ years of experience and hundreds of completed inspections is usually more reliable than a newer one.
You can attend the inspection, and you should. Walk through with the inspector, ask questions, and take notes. This gives you a chance to understand the findings firsthand rather than relying only on the written report. Some inspectors offer a follow-up call to explain the report if you have questions later.
What happens if the inspection finds major problems
If the report lists significant issues—a cracked foundation, a roof that needs replacement, mold, or outdated electrical wiring—you have negotiating power. Send the report to the seller's agent and request either repairs or a price reduction. The seller may agree, counter-offer, or refuse.
If the seller refuses to negotiate and the problems are serious enough that you no longer want the house, your inspection contingency lets you cancel the contract and get your earnest money back. This is the main reason inspections matter: they give you an exit if the house is not what you thought.
If you decide to proceed despite the problems, get a second opinion on expensive repairs. A structural engineer can assess foundation cracks; a roofer can estimate roof replacement costs. These specialist inspections cost more but give you precise information before you commit.
Inspections for older homes and newly built homes
Older homes (built before 1980) often have outdated systems, lead paint, asbestos, or foundation settling. An inspector will flag these, but you should also consider a specialized inspection for lead or asbestos if the house was built when these materials were common. These tests cost extra but matter for health and resale value.
Newly built homes may seem like they do not need an inspection, but they do. New construction can have poor workmanship, incomplete punch-list items, or code violations. Builders sometimes cut corners on systems that will not show up until after closing. A new-home inspection catches these before you take possession.
What inspections do not cover
A standard home inspection does not include pest inspections, radon testing, septic system evaluation, or well water testing. If the house is in a rural area with a well or septic system, order those tests separately. If you live in a radon zone, add radon testing to your inspection. If you see signs of termites or other pests, hire a pest inspector.
Inspections also do not cover code compliance in detail. An inspector will note obvious code violations, but they are not building code experts. If you are concerned about whether the house meets current code, hire a code official or structural engineer to review specific systems.
Frequently Asked Questions
Can I skip the home inspection to save money?
You can, but it is a significant risk. An inspection costs $300 to $500 and may reveal problems worth thousands to fix. Without an inspection, you buy the house as-is and lose your chance to negotiate repairs or walk away. Most lenders will not lend on a house you have not inspected, so you would also need to pay cash.
What if the seller will not let me inspect the house?
A seller who refuses inspection is a red flag. Your purchase contract should include inspection rights as a standard contingency. If the seller refuses, you can walk away or negotiate access. A seller who hides the house from inspection is usually hiding problems.
Do I need a separate inspection if I am buying a condo or townhouse?
Yes. Condos and townhouses have shared systems (roof, foundation, exterior walls) that the homeowners association maintains, but your unit still has plumbing, electrical, HVAC, and interior systems that need inspection. The report will note what the HOA covers versus what is your responsibility.
What if the inspection report disagrees with what the seller told me?
The inspector's written report is the official record. If the seller said the roof is new but the inspector dates it at 20 years old, the report is your evidence. You can use this to renegotiate or cancel the contract. Keep the report and all communications with the seller in case you need them later.
Can I use the inspection report to negotiate after closing?
No. Once you close, the house is yours as-is. The inspection contingency only applies before closing. This is why it is critical to resolve all inspection issues before you sign the final papers. After closing, you have no recourse based on the inspection report.
