BC Assessment
Annual assessment by BC Assessment Authority. Reflects market value as of July 1 of the prior year. Used for property tax calculation.
Market value
What a willing buyer would pay a willing seller in arms-length transaction at the current moment. Reflected in MLS sold data.
Typical lag
BC Assessment lags by 12-18 months — it is always behind a rising market and behind a falling market.
Mass calculation
BC Assessment uses statistical models on neighbourhood data, not individual property inspection. Specific property features may be over- or under-valued.
Appeal process
Owners can appeal their assessment through the Property Assessment Review Panel — typical deadline: late January each year.
Use BC Assessment for
Property tax, big-picture neighbourhood trend, baseline reference
Use MLS solds + REALTOR® CMA for
Current market value, list-price decisions, offer strategy
Common pitfall
Buyers anchoring on BC Assessment as a 'fair price' — usually behind the market in active periods
No pressure. No obligation. Just a 30-minute call to talk through your specific situation and run the numbers.
Your BC Assessment number and what your Coquitlam home would actually sell for are two different things. Here is why, and how to use each.
Timing
Assessments reflect a valuation date months before you receive them, so in a moving market they can lag what buyers are paying today in either direction.
Method
Assessments are produced at scale using broad data. They cannot see your renovations, your specific view, or the condition a buyer walks through — market value can.
Purpose
The assessment exists to distribute property taxes fairly across a municipality, not to predict your sale price. Using it as a listing price is a common, costly mistake.
Adjustments
Updates, layout, lot, exposure and street all move market value in ways a mass assessment does not capture. Two homes with the same assessment can sell far apart.
Direction
In a rising market, homes often sell above assessment; in a softening one, below. The gap is information, not error — read it in context.
Use it well
Treat the assessment as one input among several. A current comparative market analysis, not the assessment, is what should anchor a pricing decision.
The short version: your assessment is a tax tool built from last year’s broad data, while market value is what a real buyer will pay for your specific home today. When they diverge, it is usually the market value — grounded in current comparable sales — that deserves your attention when it is time to price or plan.
A practical way to use both numbers together: let the assessment reassure you that your property taxes are in a reasonable band relative to your neighbours, and let a current market analysis tell you what to actually list or offer. If your assessment and a fresh analysis of comparable sales point in wildly different directions, that gap is worth a conversation rather than a shrug — it often signals a fast-moving market, a home with unusual features, or an assessment that simply has not caught up. What you should never do is set a list price by adding a round percentage to the assessment, or lowball an offer because "it is above assessed value." Buyers and sellers who anchor on the assessment routinely leave money on the table in both directions. Anchor instead on what genuinely comparable homes are selling for right now, and treat the assessment as the tax document it was always meant to be.
Because the assessment reflects value as of July 1 of the previous year, calculated by mass appraisal without seeing your home. It typically lags the real market by 12–18 months. Market value is what a buyer will pay today, based on your property's actual condition and recent comparable sales.
No. The assessment can be well above or below current market value depending on timing and your home's specifics. Price from a comparative market analysis of recent comparable sales instead.
It sets your share of municipal property tax. The city divides its budget across all assessed properties, so your assessment determines your portion — it's a tax tool, not a selling price.
As of July 1 of the prior year. Assessment notices are mailed in January, so by the time you receive one — and certainly by the time you sell — the market has usually moved.
