Home Inspection

The home inspection process begins once a purchase offer is accepted and the inspection contingency period is established in the purchase agreement — typically 7 to 14 days after contract acceptance. The buyer selects a licensed home inspector, preferably one certified by ASHI or InterNACHI, who carries errors and omissions insurance and has specific experience with the property type and age. The inspection itself takes two to four hours for a typical single-family home, longer for larger properties. The inspector systematically examines all accessible areas of the property: the roof covering, structure, gutters, and downspouts from the exterior; the attic for insulation, ventilation, and signs of leaks; the basement or crawlspace for moisture, foundation cracks, and pest damage; all plumbing fixtures, water heater, and drainage systems; the electrical panel, outlets, and visible wiring; the HVAC system including furnace, air conditioner, and ductwork; the interior rooms, windows, doors, floors, walls, and ceilings; and major appliances included in the sale. The inspector documents each finding with photographs and assigns a severity rating: minor maintenance item, moderate concern requiring monitoring, or significant defect requiring immediate professional evaluation or repair.

After the inspection, the inspector prepares a comprehensive report, typically delivered within 24 to 48 hours, which serves as the basis for the buyer's negotiation strategy. The report includes an executive summary of the most significant findings, detailed descriptions of each issue with photographs, estimated remaining useful life of major systems (roof, HVAC, water heater, appliances), and recommendations for further evaluation by specialized contractors. The buyer then works with their real estate agent to determine which items warrant renegotiation. Industry norms suggest that safety issues, structural defects, and major system failures near end of life are reasonable repair requests, while minor cosmetic issues and items disclosed by the seller are typically not renegotiable. The buyer can request the seller make repairs before closing, provide a credit at closing for the estimated repair cost, or reduce the purchase price by the repair amount. If the parties cannot reach agreement, the buyer may typically terminate the contract under the inspection contingency and receive their earnest money deposit returned in full. According to the National Association of Realtors 2024 Home Buyer and Seller Generational Trends report, 62% of home buyers included an inspection contingency in their offer, and among those who conducted inspections, 76% received a concession from the seller averaging $8,200.

There are several specialized inspection types beyond the general home inspection that may be recommended depending on property characteristics. A pest inspection (also called a wood-destroying organism inspection) is required by many lenders in certain regions and checks for termite, carpenter ant, and fungal damage. A radon test measures airborne radon levels; the EPA recommends mitigation if levels exceed 4.0 picocuries per liter. A sewer scope inspection uses a camera to examine the main sewer line from the house to the municipal connection or septic system — often recommended for older homes with cast iron pipes that are prone to collapse. A mold inspection tests for elevated spore levels or toxic mold species, particularly relevant in properties with moisture issues or prior flooding. A lead-based paint inspection is required for homes built before 1978 under the Residential Lead-Based Paint Hazard Reduction Act, and sellers must disclose known lead hazards. An HVAC-specific inspection by a licensed contractor is sometimes recommended when the general inspector notes concerns about the furnace or air conditioning system. Each specialized inspection adds $150 to $500 but can uncover critical issues that a general inspection might only flag for further evaluation. Buyers of homes in certain regions should also consider flood zone determination and wind mitigation inspections, which may affect insurance premiums by hundreds of dollars annually.

The home inspection is one of the most financially impactful steps in the home buying process, yet it is surprisingly undervalued by many first-time buyers. A 2024 survey by Clever Real Estate found that 22% of recent home buyers waived their inspection contingency to make their offer more competitive in a tight market — a decision that backfired for 65% of them, who later discovered major defects averaging $15,000 in unexpected repair costs within the first year of ownership. Waiving the inspection is the equivalent of buying a used car without a mechanic's inspection; it transforms a known-cost purchase into an open-ended liability where the buyer assumes all risk of hidden defects. Even in competitive markets, buyers should consider alternatives to a full waiver: offering a pre-offer inspection (conducting the inspection before making the offer), agreeing to a pass-fail inspection (committing not to negotiate on repairs under $2,000), or limiting the inspection to structural and mechanical issues only. These compromises maintain some buyer protection while presenting a more attractive offer to sellers who want certainty.

Beyond the obvious benefit of identifying defects before purchase, the home inspection provides crucial information for budgeting and insurance planning. The inspection report's estimated remaining useful life of major systems — typically 15 to 30 years for roofs, 15 to 20 years for HVAC, 10 to 15 years for water heaters, and 30 to 50 years for major appliances — allows new homeowners to build a capital reserve fund for future replacements. A buyer purchasing a home with a 12-year-old roof and 18-year-old furnace should budget approximately $15,000 in replacement costs within the next 3 to 8 years. The inspection also identifies potential insurance issues: outdated wiring, old plumbing, or roof condition may affect homeowner's insurance eligibility or premiums. Some insurance companies require a Certificate of Inspection or four-point inspection for homes over 25 years old before issuing a policy. Finally, the inspection provides a detailed baseline for the property's condition, which is useful for warranty claims, contractor estimates, and resale disclosure requirements. Borrowers should attend the inspection in person to ask questions, observe the inspector's process, and learn about the home's systems — the educational value of spending three hours with a knowledgeable inspector often exceeds the monetary value of the inspection report itself.
