The gap narrows further when supply is tight. At 1.63 months of supply, well priced listings attract offers quickly, and much of the perceived delay with an agent actually comes from an overpriced listing sitting on the market, not from the listing process itself.
What that extra time buys is real. A licensed agent markets to the full buyer pool through the MLS System rather than a single investor, and a lawyer regulated by the Law Society of Saskatchewan protects the seller through the closing rather than leaving the paperwork to the buyer's side alone.
A short delay for meaningfully more money is usually the better trade, but the right answer depends on how much delay you can actually afford. Get your hand-reviewed valuation from Joel Dyck.
