Common Home Inspection Issues
A long home inspection report is normal, not a verdict: no house is without faults, and most findings are either routine maintenance or negotiating material rather than deal-breakers. The skill is telling the critical items — foundation movement, aluminum wiring, failing panels — from the ones that can wait, and knowing which findings can affect your appraisal and loan. As the lender on many West Michigan deals, we read these reports through exactly that lens.
What does the inspection report really mean?
An inspection’s outcome can significantly affect a home sale — if buyers panic over the repair notes, the deal itself can wobble. Industry inspectors are quick to remind buyers that every house has faults and every problem in a house can be fixed; the decision about what to address first lies with the buyer, seller, and their agents.
Inspectors look over the home’s structure and major systems like electricity and plumbing, then write up and explain their findings. Some items need fixing right away; others become planned future repairs or price negotiations. If you are using an FHA, VA, or USDA loan, some findings also intersect with the appraiser’s checklist — our post on property requirements for FHA, VA, and USDA loans covers which ones.
Understanding the big warnings
Some issues look scarier on paper than they usually are. Typical national repair-cost ranges below are ballparks — local quotes rule.
Structural or foundation concerns
If a house is settling wrong, it can cause big problems later. Inspectors check for signs of trouble, like cracks in the foundation or walls. Small cracks may just need monitoring, but a big crack with a bulge needs immediate expert review — as do doors that will not close right or noticeably uneven floors. Addressing these early prevents expensive repairs down the line.
- Cost: Fixing foundation issues averages between $2,000 and $8,000, depending on the extent of the damage.
Aluminum wiring
Homes built between 1965 and 1973 may have aluminum wiring. Modern homes use copper because aluminum can wear faster and overheat, raising fire risk — and some homeowners do not even know they have it. It is not a guaranteed hazard, but insurance companies often will not cover homes with aluminum wiring, so inspectors suggest talking to an insurance agent or mitigating with special connectors.
- Cost to rewire a house: On average, about $16,000.
Electrical panels
A frequent finding is two wires on one breaker where each should have its own — usually a straightforward fix. Older panels, like Zinsco and Federal Pacific units from the 1950s-1980s, get flagged because they can fail and pose fire risks, and not all insurers will cover homes that still have them.
- Cost for a new electrical panel: Typically around $2,400.
Plumbing
Minor issues — a loose hose, a dripping tap — are common and worth fixing before they invite mold. Inspectors also flag polybutylene plastic pipes (used 1978-1994, leak-prone) and old cast iron or galvanized pipes that rust. These do not always need immediate replacement, but they belong in your planning, especially in older homes.
- Cost to replace plumbing pipes: From $1,500 to $15,000, depending on the house and the pipe type.
Floor joists
Inspectors check wooden beams and floor joists for rot — and for cuts made by past renovations, which can weaken the structure and eventually show up as wall cracks or uneven floors.
- Cost for repair: Averages around $12,500 for major work, but can run as little as $100 up to $2,000 per beam.
HVAC systems
On gas systems, inspectors check the heat exchanger and the flame’s color. A wrong flame color can indicate a crack — potentially dangerous, and a precursor to a broken furnace or gas leak.
- Cost for replacement: Between $5,000 and $12,000 on average.
Safety concerns
Inspectors flag anything hazardous: cracks where you walk, missing railings, and absent smoke or carbon monoxide detectors.
Drainage issues
The exterior check covers gutters and how water flows away from the house. Poorly directed water leads to damage and leaks later.
- Cost for gutters: New gutters usually run between $624 and $1,705.
How findings connect to your financing
A big report does not mean everything must be fixed right away — it is a detailed look at the house so you know what you are getting into. Some items warrant a specialist’s closer look; others just need watching. What matters for your loan: significant safety or structural items can surface in the appraisal, and repairs can be handled through seller concessions, price negotiation, or renovation financing like an FHA 203(k) loan that rolls the work into the mortgage. Send us the report and we will tell you which findings actually touch your financing — most do not, and few should stop you from buying the house.
