Top 10 Deal-Killing Issues Found During Home Inspections in Missouri

When you're buying or selling a home in Missouri, the home inspection can make or break the deal. While some issues are minor and easy to fix, others are red flags that can stop a sale in its tracks. At UR Home Inspections, we’ve seen it all—and here are the top 10 deal-breaking problems that every buyer and seller should be aware of.

1. Foundation Cracks and Structural Issues

Large horizontal cracks, sloping floors, or sticking doors can point to major structural movement. These repairs are expensive and raise serious concerns about safety and longevity.

2. Roof Damage or Age

A roof nearing the end of its life—or worse, actively leaking—can derail a sale. Missing shingles, sagging, and poor drainage are signs that a full replacement might be needed soon.

3. Water Damage and Mold

Water intrusion isn’t just about visible stains. It can lead to toxic mold, hidden rot, and compromised air quality—issues that are big red flags for buyers and lenders alike.

4. Termite Damage

Missouri homes are especially vulnerable to termites. Damaged wood, mud tubes, and hollow-sounding beams are all signs of infestation. A termite inspection is essential and could be the difference between a smooth sale and a canceled contract.

5. Electrical Panel and Wiring Issues

Outdated or unsafe panels (like Federal Pacific), knob-and-tube wiring, or improper DIY work pose serious fire hazards. These often require full upgrades before a buyer will proceed.

6. Plumbing Problems

Old piping materials like galvanized steel or polybutylene can cause low water pressure, leaks, and future water damage. Sewer line clogs or failures are another deal-breaker—especially if there’s no sewer scope inspection done.

7. HVAC System Failures

Non-functional or inefficient HVAC systems mean discomfort and big-ticket repair bills. If the system is old, expect it to impact negotiations.

8. Radon Levels

Missouri is a known radon zone. Elevated radon levels without a mitigation system in place often scare buyers away, especially those with children.

9. Poor Grading and Drainage

Water pooling around the foundation can lead to major structural and basement issues. If grading isn't correct, it’s a red flag for long-term moisture problems.

10. Decks and Outdoor Structures

Loose railings, improper footings, or rotting supports can turn a dream backyard into a hazard zone. These must be up to code for safety and insurance purposes.
