Cardiff Acres, Sarnia - August 2026 Real Estate Report

Cardiff Acres, Sarnia: What Your Home Is Actually Worth Right Now

If you've been glancing at your city tax assessment and feeling pretty good about it, here's a reality check. The Cardiff Acres market is moving - and not always in the direction that old paperwork suggests. Here's what's actually happening on our streets right now.

The Vibe: Houses vs. Condos in Cardiff Acres

The two property types in our neighbourhood are telling very different stories this season, and it's worth knowing which one you're sitting in.

Houses

If you own a house in Cardiff Acres, the numbers are taking a breather. The average HonestDoor Price sits at $321,324, down 0.31% from last period. The 3-month moving average is $328,554, and the predicted value of $322,309 is tracking below that - a sign that house prices here have softened slightly in the short term. Values are down 2.95% recently, and on the neighbourhood growth leaderboard, Cardiff Acres houses rank 11 out of 19 comparable neighbourhoods in Sarnia. That puts us in below-average territory for growth right now.

The silver lining? If you own a house here and rent it out, the numbers work. Estimated rent runs $1,720 per month, which translates to a rental yield of 5.96%. That is a strong return. Airbnb potential adds roughly $85 per night, ranking 19th in Sarnia for short-term rental appeal.

• Average HonestDoor Price (Houses): $321,324
• Recent price change: -2.95%
• 3-month moving average: $328,554
• Estimated monthly rent: $1,720
• Rental yield: 5.96%
• Airbnb estimate: $85 per night
• Growth rank: 11 out of 19 in Sarnia

Condos

Condos in Cardiff Acres are a different story - and honestly, a more interesting one. The average HonestDoor Price is $287,200, down 2.32% from last period. But here is the twist: the predicted value of $294,033 is actually climbing above the 3-month moving average of $269,344. That means recent momentum is pointing upward, even if the broader trend has been bumpy. Values have moved up 8.51% recently.

The catch? On the growth leaderboard, Cardiff Acres condos rank 18 out of 19 neighbourhoods in Sarnia. That bottom-of-the-pack position means we are not the hottest condo market in the city right now. Nearby neighbourhoods like Coronation Park, Sherwood Village, and College Park are all priced slightly higher for condos. Rental yield sits at 4.21% - moderate, but not as punchy as the house side.

• Average HonestDoor Price (Condos): $287,200
• Recent price change: +8.51%
• 3-month moving average: $269,344
• Estimated monthly rent: $1,583
• Rental yield: 4.21%
• Airbnb estimate: $77 per night
• Growth rank: 18 out of 19 in Sarnia

The Secret Sauce: Why Your HonestDoor Price Matters More Than Your Tax Assessment

Here is the thing about your city assessment - it is a snapshot from the past. It does not know that house values in Cardiff Acres have shifted 2.95% recently. It does not know that condo momentum just jumped 8.51% in a short window. It is a static number doing a poor job of describing a moving target.

The HonestDoor Price is updated in real time using actual market data. It is the number that reflects what a buyer would likely pay today - not what the city calculated months or years ago. For Cardiff Acres homeowners, that gap between the assessment and the HonestDoor Price could mean thousands of dollars of misunderstanding about what you actually own. Checking your HonestDoor Price right now is the fastest way to get an honest read on where you stand.

The "So What?" - Thinking About Selling This Summer?

If you own a house in Cardiff Acres and are thinking about listing this summer, the timing conversation is real. Prices are softer than the 3-month average, and our growth rank of 11 out of 19 tells us we are not leading the pack. That does not mean do not sell - it means price it right from day one. Buyers are paying attention, and an overpriced listing in a cooling stretch will sit.

If you own a condo, the recent 8.51% value jump is worth watching. That kind of short-term move can create a window - but with a growth rank of 18 out of 19, the longer trend is not your friend. If you have been on the fence, a summer listing while that recent momentum is still fresh could make sense.

Either way, the neighbourhoods around us - Coronation Park, Sherwood Village, and College Park - are all priced higher. That tells us Cardiff Acres still has room to grow relative to our neighbours. We are not the most expensive street on the block, and that is actually an argument buyers will hear.

Bottom line: do not guess what your home is worth this summer. Pull your HonestDoor Price, compare it to your assessment, and make decisions based on what the market is actually saying - not what a piece of government paperwork says it said last year.
