Top things that fail home inspections
Quick insights
- A home inspection typically takes place after your offer is accepted and may uncover both minor defects and major safety or structural concerns.
- Significant issues like roof damage, electrical hazards, plumbing issues, structural defects, HVAC failures, mold or pest infestations are typically red flags.
- While a home doesn’t technically “fail” an inspection, significant findings can threaten mortgage approval, cause delays or call for negotiations.
Buying a home for the first time is a big step, and the home inspection can greatly influence the transaction. If you’re searching for “things that fail a home inspection” or worried you’ll hear “failed home inspection,” you’re not alone.
In this article, we’ll break down the home inspection process and which issues are most likely to raise serious concerns.
Why does a home inspection matter?
A home inspection typically takes place after your offer is accepted but before closing. Unless you waive the inspection in your offer, you can hire an independent, licensed home inspector.
The inspector conducts a visual evaluation of the property, examining everything from the roof and exterior to the foundation and major interior systems. Key areas of focus include the roof, structure, electrical system, plumbing, heating and cooling systems, insulation, ventilation and visible signs of water damage or pests. The purpose is to identify potential safety hazards, code concerns and costly repairs that may not be obvious during a walk-through.
Can a home fail inspection?
It’s important to clarify: A home inspection is not technically a pass-or-fail test, even though you’ll sometimes hear the phrase “failed home inspection.” Instead, the inspector delivers a detailed written report outlining observed issues, ranging from routine maintenance items to major defects.
Issues that can cause a sale to fall through
Every home inspection is unique, but certain issues tend to raise red flags more often than others for homebuyers, mortgage lenders and insurance providers. Any of these problems can derail a purchase if a seller will not, or cannot, resolve them. In some instances, multiple major issues appear in a single inspection report. When significant repairs stack up, homebuyers may walk away and continue their home search.
Roof damage or aging
Whether it’s heavy wear, active leaks or missing shingles, roof problems can top an inspection report. That’s because large roof issues impact the safety and habitability of the home. Roof repairs or replacement can be expensive, and unresolved roof damage may make it difficult to secure homeowner’s insurance or obtain mortgage approval. Lenders and insurers often want confirmation that the roof has sufficient remaining life.
Electrical system issues
Inspectors may identify hazards related to the wiring (including knob and tube or aluminum wiring), electrical panels, grounding and exposure, to name a few. More specifically:
- Aluminum wiring: Some older homes used aluminum instead of copper for wires. Aluminum can overheat more easily than copper, which poses a fire risk.
- Overloaded electrical panels: This is like a traffic jam for electricity. Too many wires or devices connected at once can cause the system to overheat or break.
- Poor grounding: Think of grounding as a safety path for electricity. If it’s not done right, electricity might flow where it shouldn’t, which can shock someone or damage appliances.
In short, these are all ways electricity can be very dangerous or unreliable, so it’s essential for inspectors to pay close attention. Electrical defects pose safety risks and are commonly flagged. Mortgage lenders may even require electrical repairs before approving a home loan.
Plumbing problems
Leaks, corroded pipes, low water pressure or visible signs of water damage can indicate larger underlying plumbing issues. Certain materials, such as polybutylene pipes (used in many homes before the mid-1990s), are known to fail prematurely and often require full replacement. These problems can quickly increase repair costs and delay closing.
Structural defects
Foundation cracks, uneven floors, bowing walls or damaged framing may signal settling, water intrusion or pest trouble. Structural concerns are among the most serious inspection findings because they are costly to repair and may affect the home’s long-term stability. Mortgage lenders rarely move ahead until these issues are evaluated and addressed.
Heating, ventilation and air conditioning (HVAC) issues
Non-functioning, unsafe or outdated HVAC systems appear in many inspection reports. Because HVAC systems are important for habitability, major deficiencies often signal upcoming repair or replacement costs. In some cases, mortgage lenders or insurers may require proof that the system is operational before closing.
Mold or moisture
Visible mold, musty smells or signs of ongoing moisture can indicate chronic leaks, poor drainage or inadequate ventilation. Mold remediation can be expensive. Ongoing moisture problems may raise concerns for both insurance coverage and financing approval.
Pest infestations
Evidence of termites, carpenter ants, rodents or other destructive pests threatens both the home’s structure and occupant safety. Lenders generally require documentation that infestations have been treated and that any damage has been repaired before allowing a loan to proceed.
What if the inspection uncovers serious problems?
A “failed home inspection” usually means the inspection uncovered major problems. They could delay the sale of the home, require substantial repairs or lead to changes in the purchase terms. The inspection itself is not a verdict. Instead, its findings become a tool for homebuyers and sellers to decide how they’ll move forward.
After receiving a concerning inspection report, buyers usually have several options:
- Negotiate with the seller to complete necessary repairs before closing.
- Request a price reduction or seller credit to help cover repair costs after moving in.
- Arrange a follow-up inspection to confirm that agreed-upon repairs were properly completed.
- Walk away from the deal if the problems are too serious or can’t be resolved within the inspection contingency period.
The path forward depends on your purchase contract, the severity of the issues and the seller’s willingness to cooperate. Some loan programs, such as FHA loans and VA loans, require certain safety, health or structural concerns to be fixed before the loan can be disbursed.
How first-time buyers can avoid surprises
You can’t predict every inspection result, but there are practical steps first-time homebuyers can take to reduce risk and limit surprises:
- Carefully review the seller’s property disclosures for any known issues. Property disclosures are often provided before you submit an offer.
- Use a pre-inspection checklist during walk-throughs to note visible concerns, such as roof condition, water stains, unusual odors or signs of moisture. What you are able to see may indicate deeper problems.
- Hire a licensed, reputable home inspector. Ask about their credentials, sample reports and experience before selecting one.
- Attend the inspection yourself if possible. Being present allows you to ask questions and better understand the severity of any findings.
- Work with an experienced real estate agent who can identify warning signs, possibly accompany the inspection and explain repair expectations.
- Plan a financial cushion for potential repairs, so inspection results do not jeopardize your budget or peace of mind.
In summary
While not every finding has to be a deal-breaker, the home inspection is an important protection you have as a homebuyer. The process helps uncover safety risks, major defects and costly repairs that may not be obvious during a showing. Major issues are worth addressing or negotiating, depending on the purchase agreement and situation. Preparation and awareness go a long way toward creating a smoother, safer and more informed homebuying experience.
