Flush toilets and turn on faucets simultaneously to check water pressure. Look under sinks for signs of active leaks or corroded pipes. 4. Windows and Insulation Drafty windows can skyrocket your utility bills.

While your own walkthrough is essential, it is a replacement for a professional home inspection. A certified inspector has the tools (like thermal cameras and moisture meters) to see what you can’t. Use your personal inspection to decide if you want to make an offer; use the professional inspection to decide if you want to close the deal.

Cosmetic cracks in drywall are common as houses settle, but structural issues are a dealbreaker.

Check your phone's signal strength in various rooms.

Ensure the home doesn't have outdated wiring (like knob-and-tube) or a recalled electrical panel (such as Federal Pacific), which can be fire hazards and make the home uninsurable. 2. Foundation and Structural Integrity

Ask for the roof’s age. Look for missing shingles, "cupping" (edges curling up), or heavy moss growth. Check the attic for water stains or daylight peeking through.

Check if doors and windows stick or won't close properly—this often indicates a shifting foundation.

Check the manufacturing dates on the furnace and AC unit. If they are over 15–20 years old, they are nearing the end of their lifespan.
