A home inspection is one of the most important steps in any real estate transaction. For buyers, it shows you what you’re actually buying. For sellers, it either confirms the asking price or throws a wrench into the deal.
Most inspections turn up minor maintenance items. But certain findings can stall negotiations or blow up a transaction entirely. Knowing what to watch for helps both sides walk into the process with eyes open.
These are the most common inspection red flags that put deals at risk, and how to handle them.

1. Major Foundation and Structural Issues
This is the one that scares everyone, and for good reason. In areas with expansive clay soil like Central Texas, foundation problems are common and almost never cheap to fix.
What the inspector looks for
Large, jagged cracks in exterior brick or interior drywall (especially over doorways), doors and windows that stick or won’t close properly, sloping floors, and gaps between the foundation and walls.
Foundation repairs can easily run tens of thousands of dollars. Worse, they can signal ongoing soil movement or drainage problems that keep affecting the house even after repairs. You’ll want a structural engineer, not just a foundation company, to evaluate the situation.
2. A Failing Roof and Evidence of Leaks
The roof keeps everything else dry. When it fails, you get water damage, wood rot, and mold, often all at once.
What the inspector looks for
Active leaks identified with a thermal camera, water stains on the ceiling, missing or curling shingles, soft spots in the roof decking, and the roof’s age. A standard asphalt shingle roof lasts about 20-25 years.
A full roof replacement is a major expense that most buyers haven’t budgeted for. Insurance companies may also refuse to cover a home with an old or damaged roof, which can make it impossible to get a mortgage.
3. Outdated or Hazardous Electrical Systems
Bad wiring isn’t just an inconvenience. It’s a fire hazard. Inspectors pay close attention to the age and condition of the electrical panel and wiring throughout the house.
What the inspector looks for
Outdated knob-and-tube or aluminum wiring, ungrounded outlets, double-tapped breakers, and signs of DIY wiring. They’ll also flag recalled panels from Federal Pacific or Zinsco, both known fire risks.
Rewiring a house is expensive, invasive work that requires a licensed electrician. Lenders and insurers may require electrical issues to be fixed before they’ll close.
4. Significant Plumbing and Sewer Line Problems
Plumbing issues range from annoying to catastrophic, sometimes with very little warning.
What the inspector looks for
Active leaks under sinks or in walls, low water pressure throughout the house (which can indicate failing galvanized pipes), signs of sewer line problems like slow drains or backups, and the condition of the water heater.
Fixing a leaky faucet is one thing. Replacing old pipes or repairing a main sewer line can cost thousands and often means digging up the yard.
5. Mold and Widespread Water Intrusion
Where there’s mold, there’s a moisture problem. A little mildew in a shower corner is normal. Widespread mold is not.
What the inspector looks for
Visible mold on walls or ceilings, a persistent musty smell, high moisture readings in drywall, and signs of poor ventilation or drainage that create a damp environment.
Mold can cause real health problems, and professional remediation is expensive. You also have to fix the source of the moisture, whether that’s a roof leak, a plumbing issue, or a foundation problem, or the mold will come back.
FAQs
Should I automatically walk away from a deal if the inspection finds a red flag?
Not necessarily. An inspection report is a negotiation tool. If a major issue turns up, you have options during your option period: ask the seller to make the repair, ask for a credit at closing, negotiate a lower sale price, or terminate the contract if no agreement can be reached. Your decision depends on how bad the issue is, what it costs to fix, and how much risk you’re comfortable taking on.
Who pays for repairs after a home inspection?
It’s negotiable. A seller can agree to pay for all, some, or none of the requested repairs. In a seller’s market, they’ll be less willing to budge. In a buyer’s market, they may be more flexible to keep the deal together.
What is the difference between a “red flag” and a minor repair?
Cost, safety, and structural impact. A loose handrail, a dripping faucet, or a broken light fixture are minor repairs. A cracked foundation, a failing roof, or a faulty electrical panel are red flags because they’re expensive, they can make the home unsafe, and they affect its core structure.
Can a seller refuse to make any repairs?
Yes. A seller has no obligation to make repairs. If they refuse, the buyer decides whether to accept the property as-is or walk away during the option period.
Can a home inspection really kill a deal?
Yes. Structural damage, major roof problems, or safety hazards can cause buyers to walk away or lenders to deny financing.
Should sellers fix everything before listing?
Not always. Minor cosmetic issues probably don’t need fixing before you list. But addressing major structural or safety concerns up front can prevent problems during negotiations.
Can buyers renegotiate after a home inspection?
Yes. Buyers often negotiate repairs or request credits based on what the inspection finds. The outcome depends on how serious the issues are and what the market looks like.
What is considered a major red flag in a home inspection?
Foundation problems, extensive water damage, roof failure, and unpermitted structural changes are among the most serious concerns.
Should I get a second inspection if major issues are found?
Sometimes, yes. Hiring a specialist like a structural engineer or licensed contractor gives you a more detailed analysis and accurate cost estimates.
