Riversdale is worth checking carefully before filing, because prices there vary block to block more than almost anywhere else in the city, driven by the neighbourhood's uneven pace of redevelopment over the past decade. Of 3 to 4 comparable sales nearby, one from the wrong stretch can be a poor match even when it looks similar on paper.
The strongest Riversdale filings pull comparables from the same immediate stretch, not the neighbourhood average, since a renovated infill and an untouched older house on the same street can carry very different assessed values for good reason.
Getting the comparable set right matters more here than in a more uniform neighbourhood. Get your hand-reviewed valuation from Joel Dyck.
