InterNACHI (International Association of Certified Home Inspectors)
InterNACHI is larger by its own account and leans into marketing for its members: it says it runs lead-generation sites for them and offers more than 1,000 hours of free online training. Its best-known feature for buyers is the Buy-Back Guarantee: if a participating Certified Professional Inspector misses something, InterNACHI will buy the home back for the purchase price. The conditions are narrow: primary residence only, the home must be listed with a licensed agent, a 90-day window after closing, and you pay fees and commissions.
