Top 10 Common Home Inspection Issues Buyers Shouldn’t Ignore

A home inspection isn’t just a formality—it’s your chance to understand what you’re really buying. Skimming the report or ignoring red flags can lead to major expenses down the line. Whether you’re eyeing your first place or your forever home, here are 10 issues that should always make you pause—and why they matter.

1. Roof Damage 🏚️

Missing shingles, soft spots, or signs of poor drainage can mean leaks, mold, and costly repairs. Roofs aren’t cheap, and if it’s nearing the end of its life, that’s a negotiation point—or a walk-away moment.

2. Electrical Hazards ⚡

Outdated wiring, overloaded circuits, or sloppy DIY jobs are more than annoying—they’re dangerous. Think knob-and-tube wiring, improper grounding, or exposed connections. A fire hazard isn’t worth the gamble.

3. Plumbing Problems 🚿

Leaky pipes, low water pressure, or corroded lines often point to bigger problems. Galvanized pipes? Plan for future replacements. Plumbing issues also invite mold—and that’s another layer of trouble.

4. Foundation Cracks 🧱

Not every crack is serious, but wide, horizontal, or shifting ones can signal structural issues. If the house isn’t on solid ground, repairs can be invasive and expensive.

5. HVAC Issues 🌬️

Old or poorly maintained heating and cooling systems mean inefficiency and costly replacements. Always check the age, condition, and service history of the units. No one wants to move in and immediately sweat—or freeze.

6. Mold and Moisture ☣️

Mold isn’t just a cosmetic issue—it can be harmful to your health. Moisture behind walls or in crawl spaces can signal drainage problems, leaks, or poor ventilation.

7. Poor Insulation or Ventilation ❄️

Inadequate insulation leads to high energy bills and uncomfortable living conditions. Poor attic ventilation can also damage your roof over time. These problems are easy to overlook until you see the impact on your wallet.

8. Pest Infestations 🐜

Termites, rodents, or ants can do more damage than you think. Even small signs—droppings, chew marks, nests—can hint at a bigger issue hiding behind the walls.

9. Drainage and Grading Problems 💧

If water collects near the foundation or flows toward the house, you’re looking at future flooding or foundation trouble. It’s often fixable, but sometimes it’s a red flag for larger problems.

10. Appliance and Fixture Failures 🔧

The dishwasher, water heater, or stove might seem minor—until they break right after closing. Knowing what’s working (and what’s not) helps you plan or negotiate before the deal is done.

Bottom Line:

A home inspection is more than a checklist—it’s your reality check. Every issue on this list could mean thousands in repairs, major safety risks, or just plain hassle. Take the report seriously, ask questions, and get professional opinions when needed. If the fixes are too big and the seller won’t negotiate, it might be time to walk.

Buying a home is exciting—but buying smart is essential.
