Skip add-ons unless there's a reason: thermal imaging and drone roof checks are for specific suspicions, not every house.

Ask about pre-auction pricing: If you're outbid you still pay, so some inspectors discount repeat bookings.

Compare on scope, not price: A cheap report that misses the subfloor is the expensive option.

Use the report: Most findings are negotiation leverage on price or repairs before settlement.

What's the difference between a building and a pest inspection?
The building inspection covers structural and general defects. The pest inspection covers termite and timber-pest activity and damage. Most buyers combine them.
