Wiltshire, Sarnia - August 2026 Real Estate Report

Wiltshire, Sarnia: Here's What Your Home Is Actually Worth Right Now

If you've been glancing at your city tax assessment and feeling pretty good about it, we need to talk. The Wiltshire market is moving - and not always in the direction that old piece of paper suggests. Here's the real picture for homeowners on our street.

The Vibe: Houses vs. Condos in Wiltshire

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

Houses: The average HonestDoor Price for a house in Wiltshire sits at $636,930, down a small 0.34% from the previous period. The predicted forward value comes in at $639,121, but here's the number that should get your attention - that figure is sitting below the 3-month moving average of $657,659. That gap tells us house values have taken a breather recently. On the neighbourhood leaderboard, Wiltshire houses rank 16 out of 19 for growth in Sarnia. That puts us near the bottom of the pack right now. Not a panic moment, but not a reason to sit on your hands either.

• Average HonestDoor Price (Houses): $636,930
• Predicted Market Value: $639,121
• 3-Month Moving Average: $657,659
• Recent Value Change: -4.49%
• Growth Rank in Sarnia: 16 out of 19
• Estimated Monthly Rent: $3,047 - $3,055
• Rental Yield: 5.36%
• Airbnb Estimate: $151 - $152 per night
• Airbnb Rank in Sarnia: 7

Condos: Our condo story is more interesting. The average HonestDoor Price is $305,864, down 2.63% recently. But the predicted value of $314,118 is actually climbing above the 3-month moving average of $289,043 - meaning the forward momentum is turning positive. Condos rank 13 out of 19 in Sarnia for growth, which puts us in below-average territory, but the trajectory is heading in the right direction. A 9.79% recent change in predicted value is a number worth watching.

• Average HonestDoor Price (Condos): $305,864
• Predicted Market Value: $314,118
• 3-Month Moving Average: $289,043
• Recent Value Change: +9.79%
• Growth Rank in Sarnia: 13 out of 19
• Estimated Monthly Rent: $1,643 - $1,683
• Rental Yield: 4.18%
• Airbnb Estimate: $81 per night

One more thing worth noting - compared to nearby neighbourhoods like Guthrie ($454,610 for houses), High Park ($382,887), and Oak Acres ($474,865), Wiltshire houses are priced significantly higher. We're the premium option on this part of the map.

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

Here's the thing about your city assessment - it's a snapshot from the past. It doesn't know what happened to comparable sales last quarter. It doesn't adjust when the 3-month moving average shifts by $18,000. It just sits there, frozen in time, while the actual market keeps moving.

The HonestDoor Price is a real-world check updated in real time. For Wiltshire house owners, that means knowing your home is sitting at $636,930 today - not whatever number the city stamped on your file months ago. For condo owners, it means seeing that predicted values are actually climbing even while the recent average dipped. That's the kind of nuance a static assessment will never show you.

If your tax assessment is higher than your HonestDoor Price, that's a conversation worth having with the city. If it's lower, you now know you have more equity than the government thinks you do. Either way, you deserve the accurate number.

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

For house sellers in Wiltshire, the honest answer is this - the window is there, but timing matters. Values have pulled back 4.49% recently, and sitting at rank 16 of 19 for growth means we're not leading the Sarnia charge right now. That said, a predicted value of $639,121 and a rental yield of 5.36% means buyers with investment intent still have a real reason to look at Wiltshire. A well-priced house here can move.

For condo sellers, the momentum shift is actually working in your favour. The predicted value of $314,118 is running ahead of the 3-month average - that's a sign the floor may be firming up. If you've been waiting for a better moment than six months ago, this might be it.

Bottom line - if you're a Wiltshire homeowner and you haven't checked your HonestDoor Price lately, do it before you make any decisions. The market isn't standing still, and neither should you.
