If you have been glancing at your latest property assessment and feeling pretty good about yourself, hold on. The real-world numbers tell a different story right now in Sun Valley - and knowing the gap could save you from a costly mistake this summer.
Sun Valley is taking a breather. Neighbourhood growth is down 0.01% year over year, and whether you own a house or a condo, values have been drifting lower over the past few months. Here is the honest breakdown for each property type.
If you own a house here, the city assessed it at an average of $1,260,593. But the HonestDoor Price - the number that actually reflects what buyers are doing right now - sits at $1,209,863. That is a gap of over $50,000, and the HonestDoor Price has slipped another 0.21% from the previous period. The 3-month moving average for predicted value is $1,230,943, and the current predicted value of $1,212,365 is already trending below that. The market is moving, and not upward.
On the neighbourhood leaderboard, Sun Valley houses rank 4 out of 6 for both growth and price among comparable Port Coquitlam neighbourhoods. That puts us in below-average territory. Oxford Heights is pulling ahead at a predicted $1,315,356, while Birchland Manor sits cheaper at $1,195,466. We are in the middle of the pack, but the trend line is pointing down.
The condo picture is rougher. The city assessed Sun Valley condos at an average of $653,683, but the HonestDoor Price is $590,532 - a gap of nearly $63,000, or 9.66% below assessment. On top of that, the HonestDoor Price has dropped 3.97% from the previous period. That is a meaningful move in a short time.
On the neighbourhood leaderboard, Sun Valley condos rank dead last - 6 out of 6 - for growth in Port Coquitlam. Nearby Birchland Manor condos are sitting at $738,262, which is noticeably higher. If you own a condo here and have been waiting for the right moment, that window is not getting wider.
Your BC Assessment number is a snapshot from July 1st of last year. It does not know what happened to the market in the months since. The HonestDoor Price is updated in real time using actual sales data, current market signals, and what buyers are genuinely paying today.
In Sun Valley right now, that difference is not small. For houses, the HonestDoor Price is over $50,000 below the assessed value. For condos, it is nearly $63,000 below. If you price your home based on the assessment alone, you risk sitting on the market while buyers - who are doing their homework - walk past.
Think of the HonestDoor Price as your real-world check. It is the number a serious buyer is likely to anchor to when they make an offer.
Here is the straight answer: if you are thinking about selling, sooner is better than later based on what the data is showing us right now.
Values are drifting lower across both houses and condos. The 3-month moving averages are above current predicted values - meaning the trend is heading in one direction. There were only 3 total property transactions in Sun Valley in 2026 so far, which tells us buyer activity is thin. Low volume means less competition among buyers, which puts more pressure on sellers to price sharp.
The rental market does offer a reasonable backstop. Houses are pulling an estimated $4,765 per month with a 4.42% yield, and Airbnb potential ranks 5th in Port Coquitlam. So if selling does not feel right, holding and renting is a legitimate option worth running the numbers on.
But if selling is the plan, do not anchor to the assessment. Pull your HonestDoor Price, price it honestly, and get ahead of the curve before the summer market tells you what you should have already known.
