Home Inspection Red Flags

A red flag is a reason to slow down, gather evidence, and involve the right professional. It is not automatically a reason to abandon a property.

How to use this guide

Use this resource to prepare observations and questions, not to approve or reject a property by itself. Record locations, patterns, odors, sounds, dates, and seller disclosures so a qualified professional has useful context.

Start with safety and active water concerns, then review structure, exterior drainage, roof, electrical, plumbing, heating and cooling, interiors, and installed appliances.

Practical checklist

  • Active water entry, repeated staining, widespread moisture, or drainage directed toward the structure.
  • Visible displacement, significant movement patterns, sagging, or unsafe structural access.
  • Sparking, heat damage, exposed conductors, gas odor, combustion concerns, or unsafe equipment.
  • Large areas of deterioration, concealed or inaccessible repairs, and conflicting seller information.
  • Multiple related symptoms across roof, foundation, plumbing, electrical, or environmental systems.

Questions worth asking

  • Is there an immediate safety action?
  • Can the cause and full extent be determined before the contingency expires?
  • Which engineer, electrician, plumber, roofer, environmental professional, or other specialist is appropriate?
  • What written scope and local estimates are needed?
  • How do contract rights and insurance availability affect the decision?

Turn observations into decisions

Separate urgent safety issues from maintenance items and cosmetic defects. Ask for written scope, assumptions, exclusions, and price ranges from the appropriate professional. Your contract, contingency deadlines, local law, and risk tolerance determine what happens next.
