That range is a large part of why Stonebridge is one of the busiest entry points into the Saskatoon market for first-time buyers: there is genuinely something at multiple price points inside one neighbourhood, rather than one price tier for the whole area.
Newer construction here also competes directly with resale in a way it does not in an older, fully built-out neighbourhood, since a buyer comparing your resale listing may also be comparing it to a builder's current price sheet. Condition and finish level matter more in that kind of head-to-head comparison.
Which price point a specific Stonebridge property actually competes in depends on its type and age, not the neighbourhood average. Get your hand-reviewed valuation from Joel Dyck.
