Above the Saskatchewan REALTORS Association benchmark of $444,700, a home in this range is well into the upper half of the local market, and the higher price does not change the mechanics of closing, only the dollar amount that percentage represents.
Every sale still closes through a lawyer regulated by the Law Society of Saskatchewan, and title moves through Information Services Corporation regardless of price point, so the process at $750,000 looks the same as it does at half that price.
The percentage range is a starting point for planning, and your actual number should come from a listing agreement built around your specific sale. Get your hand-reviewed valuation from Joel Dyck.
