BC Assessment Watch — Detached Single-Family Homes | August 2026
Tri-Cities Detached Homes Are Listed at Half Their BC Assessed Value — What That Really Means in 2026
If you’re buying or selling a detached home in Coquitlam, Port Moody, or Port Coquitlam right now, you’ve probably glanced at the BC Assessment value and wondered what it actually tells you about price. The short answer: less than most people think — but more than most people use. Across 742 matched detached single-family homes in the Tri-Cities this week, the average list price is sitting at just 49.2% of the BC Assessment value. That is not a typo. It means sellers are, on average, listing their homes at roughly half of what BC Assessment says their property is worth. Understanding why that gap exists — and how to use it — can change how you negotiate, price, and ultimately close a deal. Browse current Tri-Cities listings →
BC Assessment values are frozen in time. Every property in British Columbia is assessed as of January 1 each year, meaning the 2026 BC Assessment reflects market conditions from January 1, 2026 — not today. By the time a home hits the market in August 2026, market conditions may have shifted significantly. In a rising market, list prices run above assessed values because the market has moved upward since the assessment date. In a softening or corrected market, list prices can fall well below assessed values. What we’re seeing in the Tri-Cities right now is the latter: an average list-to-assessed ratio of 49.2% across 742 detached homes signals that current market pricing has moved meaningfully below where BC Assessment pegged values at the start of the year. Breaking that down further: 84 properties are listed below assessed value with a ratio above 110% — meaning their list price is actually lower than BC Assessment suggested. Another 199 properties are listed near assessed value in the 90–110% range. And 58 properties are listed above assessed value, with a ratio below 90% — those sellers are pricing above what BC Assessment says, which in this environment requires strong justification. For buyers, this data is a negotiating baseline, not a ceiling. For sellers, it is a pricing reality check.

Key takeaways
When the average list price across 742 detached homes is 49.2% of BC Assessment, it tells you the market has repriced significantly since January 1, 2026. Buyers have more room to negotiate than the headline assessment number suggests, and sellers who anchor their expectations to their BC Assessment figure risk overpricing and sitting on the market.
Eighty-four detached properties in the Tri-Cities are currently listed below their BC Assessment value, meaning the seller’s asking price is already lower than what the province’s assessment model estimated at the start of 2026. These are the listings worth scrutinizing most carefully — some may represent motivated sellers, estate sales, or properties with deferred maintenance, but others may simply reflect a realistic seller in a corrected market.
The 199 detached homes listed within 90–110% of their BC Assessment value represent the most stable pricing tier in today’s Tri-Cities market. These sellers are pricing close to the assessed benchmark, which makes comparisons cleaner and negotiations more straightforward. If you’re a buyer seeking predictability, or a seller wanting to move quickly, this is the pricing range that tends to attract the most serious interest.
Fifty-eight detached homes are listed above their BC Assessment value, with list prices coming in at less than 90% of the assessed figure. In a market where the average ratio is already 49.2%, pricing above assessed value requires concrete justification — a major renovation, a premium lot, a location with demonstrated demand. Without that evidence, these listings face uphill negotiations and longer days on market.
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 that value. The 2026 BC Assessment for Tri-Cities detached homes reflects market conditions as of January 1, 2026 — not the current market. That distinction matters enormously when you’re pricing or negotiating a purchase in August 2026.
How does BC Assessment affect home prices in Port Moody and Coquitlam in 2026?
BC Assessment does not set home prices — the market does. However, BC Assessment values serve as a common reference point for buyers, sellers, and their agents when evaluating whether a listing is priced fairly. In the Tri-Cities in August 2026, the average detached home is listed at 49.2% of its BC Assessment value, which reflects how much the market has moved since the January 1 assessment date. A buyer or seller who treats the BC Assessment figure as the current market value will be working with outdated information.
Should I offer below BC assessed value when buying a detached home in the Tri-Cities in 2026?
Not necessarily — but the current data suggests there is room to negotiate. With 742 detached homes in the Tri-Cities averaging a list-to-assessed ratio of 49.2% as of August 2026, many homes are already listed well below what BC Assessment said they were worth at the start of the year. The right offer price depends on recent comparable sales, days on market, and the seller’s situation — not on the BC Assessment figure alone. Use BC Assessment as one data point in your analysis, not as your offer anchor.
Is BC Assessment accurate for detached homes in Port Moody and Port Coquitlam?
BC Assessment is a mass appraisal model that performs reasonably well across large property pools, but it is not a precise individual property valuation. For detached homes in Port Moody and Port Coquitlam specifically, the assessment can diverge significantly from current market value — especially in a year like 2026, where market conditions have shifted since the January 1 assessment date. The 49.2% average list-to-assessed ratio across 742 Tri-Cities detached homes shows how wide that gap can become. A comparative market analysis from a local REALTOR® will give you a more current and property-specific picture.
How do I use BC Assessment when buying a detached home in the Tri-Cities in 2026?
Use BC Assessment as a starting point for context, not as a pricing truth. When you find a Tri-Cities detached home you’re interested in, compare the list price to the BC Assessment value to understand where the seller is positioning relative to that benchmark. In August 2026, the average detached home is listed at 49.2% of assessed value, so a home listed significantly above that ratio may be overpriced relative to current market conditions. From there, ask your REALTOR® for recent comparable sales, review days on market, and assess any features or conditions that would justify a premium or support a lower offer.
