A home inspection is a thorough examination of a property's condition, systems, and structural integrity—typically conducted before you commit to buying. It protects you from inheriting costly surprises by identifying existing problems, safety hazards, and maintenance needs. Understanding what happens during an inspection helps you prepare, ask better questions, and make informed decisions.
What Gets Inspected
A standard home inspection covers the major systems and components that affect livability and safety. The inspector examines the foundation and structural elements, roof condition, electrical panel and wiring, plumbing and water pressure, HVAC heating and cooling systems, and insulation or ventilation. They'll also check windows, doors, appliances, and interior surfaces for damage or wear. Many inspectors use thermal imaging or moisture meters to detect hidden issues like water intrusion or inadequate insulation.
Finding and Hiring an Inspector
Start by asking for referrals from your real estate agent, though always verify their independence—you want an inspector working for you, not the seller. Check credentials: look for inspectors certified by the American Society of Home Inspectors (ASHI) or licensed through your state's regulatory body. Compare costs, which typically range from $300 to $500 for a standard residential inspection, depending on the home's size and location. Most inspectors can schedule within 3–7 days, giving you time before your purchase agreement deadline.
Platforms like Mercoly let you compare and find trusted home inspection providers in one place, making it easier to vet options and read verified customer reviews.
The Inspection Timeline
Plan for 2–4 hours, depending on the property's size and age. Older homes or those with complex systems often take longer. You should attend the inspection if possible—it's your chance to ask questions, understand issues firsthand, and learn about the home's maintenance quirks. The inspector will walk you through their findings in real time or schedule a brief summary at the end.
What Happens After the Inspection
Your inspector will deliver a detailed written report within 24–48 hours, usually as a PDF with photos, descriptions, and severity ratings. Reports categorize findings into levels:
- Safety/code violations – items that pose immediate risk or fail to meet building codes
- Major repairs – significant systems failures or structural damage (foundation cracks, roof leaks, electrical problems)
- Minor repairs – cosmetic issues or maintenance items (caulking, paint, worn caulking)
- Monitoring items – things to watch but not urgent (minor water stains, old appliances nearing end of life)
Use this report to negotiate repairs or credits with the seller, request a second opinion from a specialist (like a structural engineer or roofer), or decide whether to move forward or walk away.
Red Flags to Know About
Certain findings are deal-breakers or expensive fixes. Foundation cracks wider than 1/4 inch, signs of active water damage or mold, roof damage requiring replacement (not repair), outdated electrical panels, or failing HVAC systems in harsh climates can cost $5,000–$30,000+ to address. Don't ignore these; consult a specialist before deciding.
Inspection vs. Appraisal
These are different. An appraiser determines market value for financing purposes; an inspector assesses condition and safety. You need both. The appraisal typically happens after the inspection and may be ordered by your lender.
Cost-Saving Tips
Some inspectors offer bundle rates if you also request specialized inspections (termite, septic, radon). Radon testing ($150–$300) is worthwhile in many regions. Septic inspections ($300–$500) are essential if the home uses a septic system rather than municipal sewer. Negotiate who pays for these upfront—sometimes it's cheaper to include them in the initial inspection fee.
Frequently Asked Questions
Q: Can I skip the home inspection if the home "looks fine"? No. Serious problems like foundation shifts, electrical hazards, or plumbing blockages aren't visible without specialized equipment and training. An inspection is worth the cost to avoid buying a house with hidden $10,000+ liabilities.
Q: What if the inspection finds major problems—can I back out? Yes, if you include an inspection contingency in your purchase agreement, which most standard offers do. This gives you a set number of days (typically 7–10) to request repairs, credits, or withdraw your offer without penalty.
Q: Do I need a second opinion on certain findings? If the report flags structural, foundation, or roofing concerns, hiring a specialist inspector ($500–$1,000) is wise before renegotiating. Their focused expertise and detailed report strengthen your position with the seller.
