After training — the software decision
Training gets you licensed. Software gets you paid. The gap between licensed home inspectors and successful home inspectors comes down to how fast you can turn an inspection into a delivered report.
InspectorData is the only home inspection software with real AI photo analysis — the system reads your inspection photos and drafts comments in 7 seconds each. New inspectors using it deliver same-day reports from their very first job, which is the fastest way to earn agent referrals. The 90-day free trial (no credit card) means you can run your entire first quarter of inspections on the software before paying a cent.

Home inspector training FAQ
Answers pulled from our review of nine home inspection software platforms. Updated April 2026.
-
Do I need formal training to become a home inspector?
It depends on your state. About 30 US states require a licensed training program (60-140 hours) before you can get licensed. In unlicensed states, training is optional but strongly recommended. Even in unlicensed states, InterNACHI or ASHI membership requires some training.
-
How long does home inspector training take?
Most programs run 60-140 hours total. Self-paced online programs like InterNACHI can be completed in 2-8 weeks depending on how much time you dedicate. Structured programs like ICA School and AHIT typically take 4-8 weeks of focused study.
-
Which home inspector training is best?
For most new inspectors, InterNACHI is the best starting point — it is free with membership, covers all the major topics, and is accepted in most licensed states. If you need a more structured curriculum with exam prep, ICA School or AHIT are worth the $700-$1,500 investment. The best program is the one that meets your state licensing requirements.
-
What is the NHIE exam?
The National Home Inspector Examination (NHIE) is a 200-question exam administered by the Examination Board of Professional Home Inspectors (EBPHI). Many licensed states require passing the NHIE to get licensed. The exam costs $225 and has a roughly 70% first-time pass rate. Most training programs include NHIE exam prep.
-
Can I train for free?
Yes — InterNACHI offers free training with a $49/month membership, making it effectively free for a focused 1-2 month study period. That's $50-$100 total to complete training, compared to $700-$1,500 for structured programs. The tradeoff is less structure and no built-in exam prep.
