BC Assessment Watch — Detached Single-Family Homes
Tri-Cities Detached Homes Are Listing Above BC Assessment — What That Means for Buyers and Sellers in 2026
If you’re buying or selling a detached home in Coquitlam, Port Moody, or Port Coquitlam right now, one number deserves your attention: the average list-to-assessed ratio across detached homes with a 2026 assessment on file is 108.9%. That means the typical detached home in the Tri-Cities is listed slightly above its BC Assessment value. For buyers, that means the assessment is not a price ceiling — and for sellers, it is not a pricing guarantee either. Here’s what this data actually tells you. Browse current Tri-Cities listings →
BC Assessment sets property values once a year, frozen to market conditions as of January 1. By the time you’re shopping in mid-2026, those numbers are already six months old — and in a market that has shifted, the gap between assessed value and list price can be dramatic. Across 745 detached single-family homes analyzed in the Tri-Cities this week, 232 properties are listed near their assessed value, which represents the most stable and reliably priced segment of the market. Meanwhile, 74 properties are listed well above assessed value, signaling that sellers in those pockets believe — or have evidence — that demand has pushed prices up since January 1. And 85 homes are listed below their assessed value, meaning those sellers have priced beneath what BC Assessment says their home is worth. That last group is where buyer opportunity — and seller urgency — collides. An average ratio of about 109% across the board tells the broader story: detached asking prices in the Tri-Cities are running ahead of where assessed values were set, and a below-assessment listing stands out enough to deserve a closer look.

Key takeaways
An average list-to-assessed ratio of about 109% does not mean every home is overpriced. It means the current market, as reflected in active list prices, is running modestly ahead of where BC Assessment pegged values on January 1, 2026. This can happen when the market firms up after the assessment date, when assessed values lagged a prior shift, or when sellers price optimistically and let the market respond. Buyers should treat this ratio as a market context tool, not a negotiation shortcut.
Of the detached homes analyzed, 232 are listed within roughly 15% of their BC Assessment value. These are the listings most aligned with the assessed snapshot and tend to attract serious buyers who are using assessment as a reference point. If you’re a buyer looking for a home where pricing logic is easiest to verify, this segment offers the clearest comparison baseline. If you’re a seller, pricing in this band signals confidence and market awareness.
Seventy-four detached properties in the Tri-Cities are currently listed more than 15% above their BC Assessment value. These sellers are signaling that their specific property — whether due to location, renovation, lot size, or neighbourhood demand — has appreciated beyond what January 1 data captured. Buyers approaching these listings should request comparable sales from the past 60 to 90 days and not assume assessed value sets a ceiling. In some submarkets of Port Moody and Coquitlam, recent sales data may justify the premium.
Eighty-five detached homes are listed below their BC Assessment value — the clearest sign of motivated sellers or market-adjusted pricing in this dataset. For buyers, these listings deserve close scrutiny: are they priced low because of condition issues, a dated layout, or a seller who simply needs to move? Or has the broader market in that micro-area softened enough to justify the discount? Either way, these are the listings where a data-backed offer — anchored to recent comparable sales, not assessment — carries the most weight.
Frequently asked questions
Common questions answered
What is BC Assessment and how is it calculated for homes in the Tri-Cities?
BC Assessment is a provincial Crown corporation that estimates the market value of every property in British Columbia as of January 1 each year. For detached homes in Coquitlam, Port Moody, and Port Coquitlam, assessors use recent comparable sales, property characteristics, and neighbourhood data to set values. These assessments are used primarily to calculate municipal property taxes and are mailed to homeowners each January. In 2026, BC Assessment values for Tri-Cities detached homes reflect market conditions from January 1, 2026 — meaning they do not capture any price movement that has occurred since that date.
How does BC Assessment affect home prices when buying or selling in 2026?
BC Assessment does not set or control home prices — the market does. However, assessment values are frequently used as a reference point by buyers, sellers, and their agents when evaluating whether a listing is fairly priced. In the Tri-Cities in 2026, the average detached home is listed at about 109% of its assessed value, which indicates that asking prices are running ahead of the January 1 assessment benchmark. Sellers still need recent comparable sales to justify their price. Buyers who assume assessed value equals market value may misjudge what a home will actually sell for.
Should I offer below BC Assessment value on a Tri-Cities detached home in 2026?
Offering below BC Assessment value can be reasonable on the right listing, but your offer should be anchored to recent comparable sales — not the assessment figure itself. With 85 detached homes currently listed below their assessed value against an overall average ratio of about 109%, below-assessment listings are the exception rather than the rule. That said, a strong offer is always supported by sales data from the past 60 to 90 days in the same neighbourhood. Your REALTOR® should pull those comps and use them alongside the assessment as context, not as your sole negotiation anchor.
Is BC Assessment an accurate reflection of real estate values in Port Moody in 2026?
BC Assessment provides a useful starting point but is not a precise measure of current market value in Port Moody or anywhere else in the Tri-Cities in 2026. Assessments are frozen to January 1 market conditions, which means they can lag significantly in a shifting market. In mid-2026 the broader Tri-Cities detached segment is actually listing slightly above assessed values, which shows how far the market can drift from the January snapshot in either direction. For the most accurate valuation of a specific Port Moody home, use a comparative market analysis based on recent sold data.
How should I use BC Assessment when buying a detached home in Coquitlam or Port Coquitlam in 2026?
When buying a detached home in Coquitlam or Port Coquitlam in 2026, use BC Assessment as one data point among several — not as your primary valuation tool. Start by comparing the list price to the assessed value to understand where the seller is positioned relative to the January 1 benchmark. Then ask your REALTOR® to run comparable sold prices from the past 60 to 90 days in the same area and property type. If the list price is significantly above assessment, ask what justifies the premium. If it’s significantly below, investigate why. In the current Tri-Cities market, where the average detached home lists at about 109% of assessed value, understanding this gap gives you a meaningful negotiating advantage.
