If you've been reading anything about the Coquitlam, Port Moody, or Port Coquitlam real estate market, you've seen the term "benchmark price" or "MLS HPI". The April 2026 Greater Vancouver REALTORS® release referenced it dozens of times. Most buyers and sellers I talk to nod when it comes up but couldn't define it if their negotiation depended on it.
It does. Here's what the MLS HPI benchmark price is, how it's calculated, and why it's the single most reliable number in any conversation about Coquitlam home values.
The 30-second definition
The MLS Home Price Index (HPI) is a controlled measure of how much a typical home in a defined area would sell for, calculated using a statistical model that adjusts for property features. The benchmark price is the dollar value of that typical home at a specific point in time.
For example, the Coquitlam composite benchmark in April 2026 is $998,300. That's not the average of all April sales. It's the modelled price of a benchmark Coquitlam home — a typical detached, attached, or apartment property — controlled for size, age, location, and other features.
Why it's better than average or median sale price
Here's the problem with relying on average or median sale prices alone.
Imagine April had 49 detached sales in Coquitlam. If three of those sales happened to be on Westwood Plateau in custom-built $3M+ homes, the average sale price would jump even though the typical Coquitlam home value didn't change at all. The next month, if those three sales don't repeat, the average looks like prices "dropped." They didn't. The mix changed.
This is called mix bias, and it's why average and median price reports can mislead month-to-month.
The HPI benchmark removes mix bias by modelling the price of the same standardized home each month. If the benchmark changes, it's because actual market value changed — not because the lineup of sales happened to be different.
How the HPI is calculated (the technical version)
The MLS HPI uses a statistical method called hedonic regression. The Canadian Real Estate Association (CREA) and Greater Vancouver REALTORS® feed every MLS sale through a model that controls for:
- Property type — detached, attached, apartment
- Square footage of finished living space
- Lot size (for detached)
- Age of the building
- Number of bedrooms and bathrooms
- Location (sub-area / neighbourhood)
- Number of parking spaces
- Number of fireplaces
- Other measurable features
The model output is a price index. Each property type and area has its own index. The index value is anchored to a base period (January 2005 = 100), and the benchmark price is calculated by multiplying the current index value against the modelled price of the benchmark property.
For example, in April 2026, the Coquitlam composite price index is 315.6. That means the typical Coquitlam home is now valued at 315.6% of what it was in January 2005 — a 215.6% increase over 21 years.
Reading the April 2026 HPI for the Tri-Cities
Let me show you how to read the most recent verified GVR data so you can use the HPI yourself.
Coquitlam — April 2026
- Composite benchmark: $998,300 · −7.0% YoY · −0.3% MoM
- Detached benchmark: $1,635,700 · −7.7% YoY · +0.7% MoM
- Townhouse benchmark: $1,008,100 · −6.0% YoY · +0.1% MoM
- Apartment benchmark: $664,000 · −8.5% YoY · −0.6% MoM
Port Moody — April 2026
- Composite benchmark: $1,029,100 · −4.7% YoY
- Detached benchmark: $1,936,100 · −5.4% YoY
- Townhouse benchmark: $961,400 · −5.6% YoY
- Apartment benchmark: $703,500 · −4.1% YoY
Port Coquitlam — April 2026
- Composite benchmark: $893,000 · −6.1% YoY
- Detached benchmark: $1,326,700 · −5.7% YoY
- Townhouse benchmark: $896,900 · −5.8% YoY
- Apartment benchmark: $580,400 · −8.8% YoY
Now you can compare. A Port Coquitlam detached at $1.33M benchmark is roughly 19% cheaper than a Coquitlam detached at $1.64M, and 32% cheaper than a Port Moody detached at $1.94M. Those gaps tell you which market your dollar stretches in.
How buyers should use the HPI benchmark
Three practical uses:
- Sanity-check listing prices. A Burke Mountain detached listed at $1.95M when the Coquitlam detached benchmark is $1.64M needs a justification — oversize lot, exceptional view, recent renovation. If the listing matches the benchmark profile and is priced 15% above benchmark, the seller is testing the market.
- Set your own offer anchor. When you write an offer, you have a defensible number from a third party (CREA / GVR). That's stronger than negotiating on instinct.
- Track market direction over months. Watch the year-over-year and month-over-month changes. If the benchmark is rising 0.5–1% per month for three months in a row, the correction is over.
How sellers should use the HPI benchmark
Two practical uses:
- Calibrate your list price. Take the property-type benchmark for your sub-area, then adjust up or down for square footage, lot size, age, condition, and view relative to a "typical" property. The result is your defensible price band.
- Manage your own expectations. If a neighbour sold for $2.1M two years ago, that was a different market. Today's benchmark is the only honest reference for what your home is worth right now.
What the HPI doesn't tell you
HPI is the most reliable price-change measure, but it has limits. It doesn't account for:
- Condition. A renovated home and a tired home of the same age, size, and location have different market values.
- View, exposure, or specific street. Mountain-view properties carry premiums not captured in the benchmark.
- Land value vs improvements. A tear-down on a 10,000 sq ft lot in Burke Mountain can be priced like a custom build.
- Negotiation, motivation, or timing. Two identical homes can sell for different prices based on buyer urgency, seller flexibility, and offer structure.
This is where a REALTOR®'s local knowledge matters. The benchmark is a starting anchor. The final price comes from comparable analysis, the property's specific features, and current buyer demand for that micro-market.
HPI in plain English: an example
Let's say you're considering a Coquitlam townhome in Burke Mountain. The April 2026 Coquitlam townhouse benchmark is $1,008,100. The townhome you're looking at is 1,420 sq ft, 3-bed, 2.5-bath, with a garage and small patio.
If the listing is at $1,015,000 and the property roughly matches the benchmark profile, the listing is essentially at benchmark. That's a fair price for a typical townhome.
If it's at $1,165,000, you'd want to know what justifies the 15% premium over benchmark. New roof? Renovated kitchen? Best unit in the complex? View? Without those, you're paying a premium against the underlying market value.
If it's at $945,000, you'd want to know why it's 6% under benchmark. Strata levy? Foundation issue? Pet bylaw constraints? It might be a bargain or it might be a problem.
The benchmark gives you the anchor. Local diligence tells you which way the home moves from that anchor.
