Your tax assessment and a professional evaluation aren't two opinions. They're two different questions.

Two different questions, not two different opinions

Property assessment exists to answer one question: given a fixed budget the City needs to raise, what's each property's fair share of the tax bill? A market evaluation answers a completely different question: what would a real buyer, competing against other real buyers, actually pay for this specific house right now? Both numbers can be entirely correct and still disagree by tens of thousands of dollars, because they were never trying to answer the same thing.

Assessment is one formula, applied to everyone at once

The City doesn't walk through your home to set your assessment. It uses mass appraisal — a standardized methodology, published every year, applied consistently across roughly 439,000 properties so the tax burden is distributed fairly. That consistency is the whole point of the system, and it's a reasonable one for taxation. It also means your assessment was never built to capture what makes your specific kitchen, your specific basement, or your specific street different from your neighbour's.

It's also always at least a year old

This part is set in provincial law, not a City choice. Under Alberta's Municipal Government Act, every municipal assessment uses a fixed valuation date of July 1 of the year before the tax year. Your current assessment describes the market exactly as it stood on — — not today, and not whenever you actually list. By the time most sellers get around to selling, they're pricing against a market snapshot that's well over a year old.

What a professional evaluation adds that assessment can't

A real evaluation starts where assessment stops: live. It reads MLS® listings competing with your home right now, recent comparable sales from the last 90 days — not last year — and adjusts each one for the ways it actually differs from your home. Then it adds what no mass-appraisal formula ever sees: your condition, your recent renovations, how your basement is finished, whether your street backs onto green space. The walkthrough is what turns a data-driven range into an actual list price, because light, layout, and street appeal are the last things no dataset — assessment or otherwise — can price for you.
