The Inspection Contingency

The Inspection Contingency: 10 Deal-Breaker Findings

A home inspection is three hours and $400 to $600 that could save you $50,000—or an entire purchase. It is not a guarantee of perfection, a warranty against future repairs, or a pass/fail test. It is a structured examination of a home's current condition by a trained professional, producing a documented assessment of defects, safety concerns, and items requiring attention.

The inspection contingency in a purchase contract gives you the right to negotiate repairs, request a price reduction, or walk away based on inspection findings. Understanding which findings justify using that contingency—and how to think about the ones that don't—is knowledge that directly affects both your purchase decision and your financial exposure after closing.

WHAT AN INSPECTION COVERS

A standard home inspection examines the visible and accessible components of a home's major systems: structural elements (foundation, framing, roof), exterior (siding, grading, drainage), roofing, plumbing, electrical, HVAC, insulation and ventilation, interior finishes and components, and attic and crawl space conditions.

A standard inspection does not cover: mold testing, radon measurement, sewer scope, septic system evaluation, chimney inspection, pest inspection, pool/spa equipment, or oil tank presence. These require specialized inspections, each typically $100 to $500, contracted separately. For older homes or properties with specific risk factors, these add-ons are often worth the cost.

The inspector observes and reports; they do not open walls, move furniture, or excavate. Their assessment is visual and accessible. Issues hidden behind drywall or under insulation may not be detected until they reveal themselves—sometimes years after purchase. This is not an indictment of the inspector; it is the inherent limitation of non-invasive inspection.

THE 10 FINDINGS THAT SHOULD STOP YOU OR COST THE SELLER

1. Foundation problems

Cracks in a foundation wall or floor slab range from cosmetic to catastrophic. Horizontal cracks in block or poured concrete basement walls typically indicate lateral pressure from soil—often a serious structural issue. Stair-step cracks in block foundations or diagonal cracks from window corners may indicate differential settlement. A general inspector who flags foundation concerns should be followed by a structural engineer's evaluation ($300 to $600) before closing. Repair costs for foundation problems range from a few thousand dollars for crack injection to $30,000 to $100,000+ for helical piers, wall anchors, or underpinning. This is not a repair to accept on the seller's word.

2. Roof at end of life

A roof with 2 to 3 years of estimated remaining life becomes your problem the day you close. Roof replacement costs $8,000 to $25,000+ depending on roof size, pitch, and material. An inspector who notes "roof is 22 years old with multiple layers and signs of wear" is telling you a replacement is imminent. Get a roofing contractor's estimate and negotiate accordingly—either a price reduction or a seller credit at closing sufficient to cover replacement.

3. Active water intrusion

Evidence of active or recent water intrusion—staining on basement walls or floor, efflorescence (white mineral deposits), mold odor, watermarks on ceiling drywall—indicates a problem that will recur and worsen after closing. Minor water management (regrading, downspout extensions) is inexpensive. Active basement waterproofing systems (interior drain tile, sump pump installation) run $5,000 to $15,000. If water has reached finished living space and created mold growth behind walls or under flooring, remediation costs and unknown scope make this a potential deal-breaker.

4. Knob-and-tube or aluminum wiring

Knob-and-tube (K&T) wiring is an early 20th-century electrical system without a ground conductor, typically found in pre-1950 homes. Many insurance companies refuse to insure homes with active K&T wiring or charge significant surcharges. Replacement of an entire electrical system runs $8,000 to $20,000+ depending on home size. Aluminum wiring in branch circuits (common in homes built between 1965 and 1973) creates fire risk at connection points—remediation through COPALUM connectors or CO/ALR devices runs $1,000 to $3,000.

5. Federal Pacific or Zinsco electrical panels

Specific panel brands—Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels—have documented failure rates that have been associated with residential fires in published research. Insurance companies frequently surcharge or decline coverage for homes with these panels. Replacement costs $1,500 to $4,000 depending on amperage and market. An inspector who identifies one of these panels in place is flagging a known safety risk with a defined remediation cost—treat it as a negotiating point, not background noise.

6. Active pest infestation or significant wood damage

A separate pest inspection (often called a WDI—wood-destroying insect inspection) is standard in many regions and typically required for VA loans. Termites, carpenter ants, and wood-boring beetles cause damage that ranges from minor (surface framing) to major (structural beam compromise). Active infestations should be treated before closing with a warranty. Existing damage to structural members requires a contractor's assessment of scope and repair cost before you can evaluate whether the purchase price accounts for it.

7. HVAC systems at end of life

A furnace with an expected 20-year lifespan that's 19 years old is a furnace replacement within 1 to 3 years of closing. Central air conditioning systems typically last 12 to 20 years. Replacement costs: furnace $3,000 to $7,000; central AC $4,000 to $8,000; heat pump $5,000 to $10,000. An inspector noting "HVAC systems are original to a 1998 construction" is communicating that replacement is likely within the first years of ownership. Age and condition should directly affect your offer or negotiation.

8. Galvanized steel plumbing

Galvanized pipes—common in homes built before 1960—corrode from the inside out over decades, gradually reducing water flow and eventually failing. A home with galvanized supply lines has a whole-house replumbing in its near future, typically costing $4,000 to $15,000 depending on home size and access. Inspector notation of "galvanized supply lines with reduced flow at fixtures" describes a known endpoint—the question is timeline and cost.

9. Evidence of unpermitted work

Unpermitted additions, basement finishes, garage conversions, or electrical work can create legal, safety, and resale complications. Unpermitted work is not necessarily dangerous—but it hasn't been inspected, may not meet code, and could require expensive retroactive permitting or removal to sell the home in the future. Some jurisdictions hold the current owner responsible for bringing unpermitted work into compliance regardless of who performed it. Identifying unpermitted work before closing allows negotiation; discovering it after is your problem alone.

10. Septic system failure or age

For homes not connected to municipal sewer, the septic system is the sewage treatment infrastructure. A failing septic system—backed-up drain field, tanks in need of replacement, systems that have exceeded their design life—can cost $5,000 to $30,000+ to replace. Many lenders require a septic inspection as a condition of financing for homes with private septic systems. Even if not required, a separate septic inspection ($200 to $400) is essential due diligence on any property with a private system.

HOW TO USE THE INSPECTION CONTINGENCY

The contingency gives you several options upon receiving the inspection report:

Request repairs: Ask the seller to correct specific defects before closing. Sellers may accept, counter, or reject. Works best for clear-cut safety issues and items with defined repair costs.

Request a price reduction or credit: Rather than asking the seller to manage repairs (which introduces uncertainty about quality), request a closing credit equal to the estimated repair cost. You control the repairs post-closing.

Renegotiate the purchase price: For major findings that change the home's value, renegotiate the purchase price downward by the appropriate amount.

Walk away: If findings are severe enough—foundation failure, systemic water intrusion, end-of-life systems on a home priced as turnkey—you can terminate the contract and recover your earnest money.

Accept and proceed: Many inspection findings are normal maintenance items that don't change the fundamental value proposition. An inspector who flags a missing GFCI outlet, a dripping faucet, and a settlement crack in a driveway has done their job—these are not negotiating points, and treating minor findings as emergencies damages credibility in negotiation.

The inspection is information. How you use it determines whether you buy a home with clear-eyed awareness of what you're taking on—or discover it after closing, one expensive surprise at a time.
