Assessed value drives property tax, market value drives what a buyer will actually pay, and the two drift apart between reassessment cycles, especially after a renovation, a secondary suite conversion or simply several years of a rising market. Confusing the two leads to either overpaying tax on a stale number or underpricing a home based on an outdated one.
For anyone within a few years of a potential sale, whether prompted by downsizing, a health change or simply wanting to be closer to family, the useful move is separating those two numbers now rather than discovering the gap under time pressure later. An online estimate typically catches neither an unpermitted improvement nor a permitted one that was never reassessed.
Getting both figures right early gives an owner options instead of a scramble. Get your hand-reviewed valuation from Joel Dyck.
