Negotiating power in Saskatoon comes from knowing what similar homes actually closed at, not just what is asking. An agent working from recently sold comparables can advise you to offer below asking, hold firm on a condition, or walk away, all of which affect the final number more than any published percentage claim.
The safer way to evaluate a buyer's agent is their track record on deals like yours rather than an unverified industry-wide average, since averages from another country's market do not transfer to Saskatoon's pricing, inventory or negotiating norms.
