Financing pre-approval should happen before you start looking, ideally while still in your current province, since a lender needs to assess income and credit through the same process Canada Mortgage and Housing Corporation insures regardless of where you are moving from, and having that done removes the biggest delay once you find a home.
Remote viewings add real time to the search phase. A relocating buyer typically needs several rounds of video walkthroughs and honest agent notes before narrowing to a shortlist, compared to a local buyer who can see three homes in an afternoon.
Once you have an accepted offer, the Saskatchewan process, a lawyer-handled closing through Information Services Corporation, runs on the same 2 to 4 week timeline for a relocation buyer as for anyone else. Get your hand-reviewed valuation from Joel Dyck.
