Insurance Requirements
| Coverage | Recommended Minimum | Annual Cost |

- Skipping pre-inspection agreements — one lawsuit ends your business
- Not photographing enough — your report is your legal defense
- Ignoring agent relationships — they control your pipeline
- No continuing education beyond minimum — miss code changes, lose credibility
- Operating without proper insurance — E&O is non-negotiable
