A home inspection is cheap insurance against buying someone else's expensive problems. It's a visual assessment of the home's condition that helps you buy with eyes open and negotiate from facts.
What it covers
An inspector examines the roof, structure, foundation, exterior, plumbing, electrical, heating and cooling, insulation, and visible signs of water damage or pests. You get a report on the condition and any issues, with photos.
What it doesn't
Inspections are visual and non-invasive — inspectors don't open walls, and they don't typically cover things like radon, mould testing, sewer lines, or oil tanks unless you arrange specialty inspections. Know the limits and add specialists where the stakes are high.
Using the results
Attend the inspection if you can, ask questions, and read the full report. Use significant findings to negotiate price or repairs, or to walk away. A clean inspection still gives you a maintenance roadmap for the years ahead.
