- Independence: an engineer who does not sell the repair gives you a neutral opinion to compare contractors' bids.
- Price drivers: size and age of the building, whether a letter or a full report is needed, and whether calculations or drawings are included.
- Deadlines: for a home purchase, mention your inspection period so the engineer can schedule the visit in time.
