Relocating to Martensville rather than into Saskatoon proper is a common landing spot for buyers priced out of the city or wanting a smaller-town feel, and the Saskatchewan REALTORS Association's Saskatoon figures, including the citywide benchmark of $444,700, describe the city market, not Martensville's own.
A Martensville property outside city limits also raises different questions than a Saskatoon lot, from its own municipal water and sewer arrangements to school busing routes, none of which a Saskatoon-specific valuation will answer.
Whether Martensville or Saskatoon fits your relocation better depends on what you are actually solving for. Get your hand-reviewed valuation from Joel Dyck.
