Bottom Line
A home inspection typically costs $300-$500 and is one of the best investments in the home-buying process. The inspection protects you from expensive surprises and gives negotiating power for repairs or credits. Don’t skip specialized inspections like radon testing or sewer scope if the property warrants them — a $200 sewer scope beats a $15,000 surprise repair.
Key takeaway: The inspection isn’t pass/fail — it’s information. Use it to understand what you’re buying and negotiate fairly.
