Confirm the actual schedule, accommodation and travel before choosing a home. An expansive territory in an offer may not describe a predictable week. Assess dependent status separately; a spouse in TD may study but does not receive employment authorization.
Base logistics on the agreed assignment
Ask which absences are expected and how changes are communicated. Keep household commitments flexible if the first assignment is unresolved. Do not assume a spouse can take temporary US work to compensate for variable field income.
The decision the household actually faces is whether to commit to housing before the assignment schedule is confirmed. Both answers carry a cost and they are not symmetric. Committing early secures a school placement and a fixed address, but it assumes a rotation that may not survive the first contract change.
Waiting keeps the household mobile and postpones the school decision, which for a child partway through a year is not free either. Ask the employer for the horizon it can stand behind, either a named first project with dates or an honest statement that the schedule is set month to month, and let that answer drive the choice. Hypothetical example: a household plans around a single destination because the offer mentions a regional territory, then learns the first months are split between two metal fabrication shops several hours apart.
The territory description was accurate; it was never a schedule.
