The #1 Red Flag in a Home Inspection

As a Massachusetts home inspector, one of the most common questions I get is:

“What’s the biggest red flag you see during inspections?”

The short answer? The #1 red flag in a home inspection depends. Every home is different, and what’s considered a major issue in one property might be a minor concern in another. That said, if I had to name one deal-breaker that consistently raises the most concern, it’s structural problems.

WHY STRUCTURAL ISSUES ARE A TOP CONCERN

Structural problems - like foundation movement, rotted framing, or compromised support systems - are serious because they affect the integrity and safety of the entire home. These aren’t just cosmetic or surface-level defects. They can require:

• Expensive repairs

• Involvement from structural engineers

• Partial demolition or reconstruction

  
  

If you spot any of the following during a home inspection, it’s time to pay close attention:

• Large cracks in foundation walls

• Bowing or leaning walls

• Significant water intrusion in the basement

• Rotted floor joists or support beams

OTHER RED FLAGS THAT MATTER

While structural issues top the list, other serious concerns can also impact the value and safety of a home:

• Moisture damage: Ongoing leaks can lead to mold, rot, or insect infestations

• Electrical hazards: Outdated wiring or overloaded panels can be a fire risk

• Roof problems: Active leaks or heavy wear often mean major repairs are needed

• Sewer line issues: Hidden, costly problems that can result in messy disasters

"A failed sewer line isn't just gross, it can cost you tens of thousands in repairs and turn your yard or basement into a disaster zone. Always scope the sewer line before buying an older home." – Mark Donnelly, P.E., Structural Engineer & Architect

CONTEXT IS EVERYTHING

It’s important to remember: a red flag doesn’t automatically mean you should walk away from a home.

The purpose of a professional inspection is to give you a clear picture of what you’re buying - the good, the bad, and everything in between. Some buyers are comfortable tackling repairs, while others want a turnkey property. Knowing what you're dealing with helps you make an informed decision.
