A professional home inspection is a critical step in the real estate transaction process, providing a detailed assessment of a property's major systems and structural components. The core purpose is to identify existing or potential safety hazards, needed repairs, and signs of damage—from roof to foundation. For buyers, the inspection report provides leverage to negotiate repairs, request financial credits, or, if allowed by the contract's inspection contingency, withdraw their offer. For sellers, a pre-listing inspection can prevent surprises and streamline the sale.
What Are the Key Areas on a Home Inspection Checklist?
A standard home inspection covers the interior and exterior of a home, focusing on systems that are costly to repair or replace. Based on industry standards from organizations like the International Association of Certified Home Inspectors (InterNACHI), the assessment is visual and non-invasive. The inspector evaluates the condition of:
- Roof, chimney, gutters, and downspouts
- Foundation and structural components
- Plumbing and electrical systems
- Heating, Ventilation, and Air Conditioning (HVAC) system
- Appliances included in the sale
- Attic, basement, and crawlspaces
How Do You Assess the Home’s Exterior and Structure?
The inspection begins outside. The inspector looks for clues about the home’s maintenance and potential water issues, which are leading causes of expensive damage.
- Foundation: Are there visible cracks in the walls or signs of previous patching? The inspector checks for indicators of soil movement or pest entry points. A minor hairline crack may be cosmetic, but a widening crack could signal a structural concern.
- Drainage: Does the ground slope away from the house to prevent water pooling near the foundation? Standing water can lead to moisture intrusion in basements and crawlspaces.
- Siding and Trim: Is the paint flaking or the siding warped? This can indicate water intrusion or deferred maintenance. In older homes, the inspector may note the potential presence of asbestos-containing materials.
- Roof: What is the approximate age of the roof? The inspector looks for missing, cracked, or curled shingles, damaged flashing, and clogged gutters. These issues can lead to leaks and interior water damage.
What Do Inspectors Look for Inside the Home?
Inside, the inspection focuses on the functionality and safety of the home's core systems.
- Plumbing System: The inspector tests water pressure and drainage at all fixtures. They will note the age and condition of the water heater and check for visible leaks or corrosion on pipes. For older homes, a separate sewer scope inspection is often recommended to assess the underground line's condition.
- Electrical System: Safety is paramount. The inspector verifies that the electrical panel is modern and properly labeled, checks for the presence of GFCI (Ground Fault Circuit Interrupter) outlets in wet areas like kitchens and bathrooms, and looks for outdated wiring like knob-and-tube, which can be a fire hazard.
- HVAC System: The heating and cooling system is tested to ensure it operates correctly. The inspector will estimate its remaining lifespan and check that air filters are clean and ducts are free of obstructions.
- Attic, Basement, and Crawlspaces: These areas reveal hidden problems. The inspector looks for adequate insulation, proper ventilation, signs of water stains, mold, or pest activity. In crawlspaces, they check that structural beams are sound and that vapor barriers are installed.
How Should You Use the Inspection Report?
The final report is your roadmap for future maintenance and negotiation. Focus on major issues related to safety, structural integrity, and expensive systems rather than minor cosmetic flaws.
- For Buyers: With an inspection contingency in your contract, you can request that the seller make repairs, provide a credit at closing to cover the costs, or adjust the sale price. For significant, undisclosed issues, you may have the option to walk away.
- For Sellers: Reviewing the report allows you to address problems proactively before listing. It also sets realistic expectations and can prevent negotiations from falling apart later.
A thorough home inspection is your best tool for making an informed real estate decision. It provides a clear picture of the property's true condition, empowering you to proceed with confidence or renegotiate terms based on factual findings.
