Tri-Cities Detached Homes Are Listed 10% Above BC Assessment — What That Means for Buyers and Sellers
If you are buying or selling a detached home in Coquitlam, Port Moody, or Port Coquitlam right now, BC Assessment is likely on your radar. The latest data from the week of September 14, 2026, covering 717 matched detached single-family home listings across the Tri-Cities, shows that asking prices are running an average of 10.3% above BC Assessment values. That gap tells a specific story about where the market has moved since January 1, 2026 — and it has direct, practical implications for how you price, negotiate, and make decisions.

BC Assessment sets property values as of January 1 each year. By the time listings hit the market in September, market conditions have had nine months to shift. In the current Tri-Cities detached home market, the average list-to-assessed ratio is 110.3%, meaning sellers are, on average, asking $110,300 for every $100,000 of assessed value. This is not a red flag — it is a signal that the market moved upward after the assessment date and sellers are pricing to reflect current demand.
Breaking down the 717 properties analyzed: 235 are listed within the 95–115% range, meaning their asking price aligns reasonably closely with assessed value. These are the most straightforward properties for buyers to evaluate. Another 72 listings are priced above 115% of assessed value, which requires careful due diligence — a seller may have legitimate renovation upgrades or micro-location advantages, or they may simply be testing the ceiling. On the other side, 92 listings are priced below 95% of assessed value, which can signal motivated sellers, deferred maintenance, or properties sitting longer than expected.
For sellers, the 110.3% average ratio confirms that pricing above assessment is broadly accepted in this market — but it is not a blank cheque. Listings priced above 115% of assessment are a smaller cohort of 72 out of 717, meaning most sellers are not pushing dramatically beyond that threshold. Overpricing relative to comparable sales, not relative to assessment, is still the fastest route to a stale listing.
For buyers, the key takeaway is that BC Assessment alone should never anchor your offer. It reflects January 1 values, not September market conditions. Use the ratio to identify outliers — properties listed well above 115% of assessment deserve extra scrutiny, while those below 95% may present a negotiating opportunity worth investigating.

Key takeaways
Across 717 detached home listings in the Tri-Cities, asking prices average 110.3% of BC Assessment values. This confirms that detached home prices have risen meaningfully since the January 1, 2026 assessment date. Buyers should expect to pay above assessed value in most transactions — this is the current market norm, not an anomaly.
The largest single group — 235 listings — falls within the 95–115% band. These properties offer the clearest alignment between assessed and market value and are useful benchmarks when evaluating other listings. If a comparable home in the same neighbourhood is listed at 130% of assessment, that premium needs justification.
Ninety-two detached homes are listed below 95% of their BC Assessment value. For buyers, this group warrants due diligence: some represent genuine opportunity from motivated sellers, while others may reflect deferred maintenance or location disadvantages that the assessment does not fully capture. Never interpret sub-assessed pricing as automatic value — investigate why.
Seventy-two listings are priced above 115% of assessed value, placing them well beyond the market average. Sellers in this group may have significant post-assessment renovations, premium lots, or views that justify the premium. Buyers should request documentation of improvements and run a thorough comparable sales analysis before accepting the premium at face value.
Frequently asked questions
Common questions answered
What is BC Assessment and how is it calculated?
BC Assessment is an independent provincial authority 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, the assessed value is based on comparable sales data, lot size, building characteristics, and location factors as they existed on that specific date. The 2026 BC Assessment values for Tri-Cities properties reflect market conditions from January 1, 2026 — not current September conditions.
How does BC Assessment affect home prices in the Tri-Cities in 2026?
BC Assessment does not set home prices — the market does. However, it serves as a widely referenced benchmark. In the Tri-Cities detached home market as of September 2026, listings are running an average of 110.3% of BC Assessment, meaning the market has risen approximately 10% above January 1 values over the past nine months. Assessment figures influence buyer expectations and seller pricing strategies, but actual sale prices are determined by comparable sales, condition, and buyer demand.
Should I offer below BC Assessment value on a detached home in Coquitlam or Port Coquitlam?
Not necessarily, and not automatically. In the current Tri-Cities market, the average list price is already 110.3% of BC Assessment, meaning most sellers are not pricing at or below assessed value. Only 92 of 717 detached listings are priced below 95% of assessment. Offering below assessed value on a property already listed at 108% of assessment, for example, would likely be dismissed. Your offer should be anchored to recent comparable sales, not the January 1 assessment figure.
Is BC Assessment accurate for Port Moody detached homes in 2026?
BC Assessment is a mass-appraisal estimate accurate as of January 1, 2026, and it cannot account for individual property improvements, unique features, or market shifts that occurred after that date. In Port Moody specifically, waterfront proximity, mountain views, and lot size variability can cause significant divergence between assessed and market value. Current data shows Tri-Cities detached homes listing at an average of 110.3% of assessed value, which illustrates how much the market can move beyond the assessment date. Always use a current comparable market analysis alongside the BC Assessment figure.
How do I use BC Assessment when buying a detached home in the Tri-Cities?
Use BC Assessment as one data point among several, not as a price ceiling or offer anchor. In 2026, a practical approach is to calculate the list-to-assessment ratio for any home you are considering and compare it to the Tri-Cities average of 110.3%. If a home is listed at 130% of assessment, ask what justifies the 20-point premium above market average — renovations, lot size, views. If it is listed at 90% of assessment, ask why it is below the norm. Then cross-reference with actual recent sales of comparable detached homes in the same neighbourhood to determine a fair offer price.
