The first step is granting that authorization before you leave, drafted and witnessed to the standard the Law Society of Saskatchewan requires, since it is what lets your lawyer sign at Information Services Corporation on closing day without you there.
Next comes preparing the home, since photos, staging and a lockbox or trusted local contact matter more once you are 2,000 kilometres away and cannot run back for a forgotten showing. An agent who has done this before builds a schedule that does not depend on reaching you in real time.
Loop your accountant in early too, since a departure from Canada can trigger a Canada Revenue Agency residency review that is easier to handle before closing than after. Get your hand-reviewed valuation from Joel Dyck.
