Request records
Ask for the controller model, zone map, repair invoices and seasonal-service history. Confirm that app access and any required accounts can be transferred. Missing records are a reason for questions, not proof of a failed system.
Specify the inspection
Ask which zones and accessible components will be operated, what conditions may prevent testing and whether coverage concerns will be documented. A surface inspection cannot promise the condition of every buried connection.
Use the findings
Separate immediate repairs from optional controller or layout improvements. Get a written scope from an appropriate professional before treating an inspection note as a fixed repair price.
Useful question
After ownership changes, will I have the controller access, instructions and system information needed to operate the existing installation?
