Unionville, Markham - September 2026 Real Estate Report

Unionville, Markham: Your Neighbours Are Watching Their Home Values Climb

If you own property in Unionville and you haven't checked your HonestDoor Price lately, you're probably leaving money on the table - or at least leaving yourself in the dark. Here's the real picture of what's happening on our streets right now.

The Vibe: Houses vs. Condos in Unionville

Let's break it down by property type, because the two stories are pretty different.

Houses

We're sitting at an average HonestDoor Price of $2,099,092 for houses in Unionville. That number is moving in the right direction - up 0.49% from the previous period, and the 3-month trend backs it up. The predicted market value of $2,088,960 is running ahead of the 3-month moving average of $2,055,181, which tells us momentum is building, not fading.

• Average HonestDoor Price: $2,099,092
• Predicted Market Value: $2,088,960
• 3-Month Moving Average: $2,055,181
• Recent Value Change: 2.37%
• Average Rental Estimate: $7,020 per month
• Rental Yield: 3.78%
• Airbnb Estimate: $349 per night
• Neighbourhood Growth Rank: 7 out of 14 in Markham - above average

That 2.37% recent value change is the number to pay attention to. For a house priced around $2 million, that's roughly $47,000 in added value. Not bad for doing nothing but owning the place. On the rental side, $7,020 a month with a 3.78% yield puts us in solid "moderate returns" territory - not flashy, but dependable. And if short-term rentals are on your radar, Unionville holds the number 2 Airbnb rank in all of Markham. That's a real edge.

Condos

Our condo market tells a quieter but still positive story. The average HonestDoor Price sits at $699,974, up 0.02% from the previous period. The predicted market value of $699,850 is tracking above the 3-month moving average of $693,073, so the direction is still upward.

• Average HonestDoor Price: $699,974
• Predicted Market Value: $699,850
• 3-Month Moving Average: $693,073
• Recent Value Change: 0.38%
• Average Rental Estimate: $3,283 per month
• Rental Yield: 3.44%
• Airbnb Estimate: $163 per night
• Neighbourhood Growth Rank: 3 out of 14 in Markham - well above average

That growth rank of 3 out of 14 is the headline for condo owners. We're near the top of the Markham leaderboard. A 3.44% rental yield and $3,283 in monthly rent make Unionville condos a genuinely competitive income asset compared to most of the city.

How We Stack Up Against the Neighbours

Context matters. Every nearby neighbourhood - Markham Hagerman, Milliken East, and Markham Village - comes in cheaper than Unionville across both houses and condos. Here's the quick comparison for houses:

• Markham Hagerman: $1,593,052 avg. HonestDoor Price - about $506,000 less than Unionville
• Markham Village: $1,374,638 - roughly $724,000 less
• Milliken East: $1,203,764 - nearly $895,000 less

For condos, the gap is smaller but still clear:

• Markham Hagerman: $541,793
• Markham Village: $567,166
• Milliken East: $488,668

Unionville commands a premium. It always has. The data confirms that premium is holding.

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

Here's the thing about your city assessment - it's a snapshot from the past. The Municipal Property Assessment Corporation updates values on a cycle that can lag real market conditions by years. Meanwhile, your HonestDoor Price is recalculated using current sales data, market trends, and real-time signals. It moves when the market moves.

With Unionville house values up 2.37% recently and the 3-month trend pointing higher, the gap between what the city thinks your home is worth and what a buyer would actually pay today could be significant. For a $2 million property, even a 5% gap is $100,000. That's not a rounding error - that's a real financial blind spot.

Checking your HonestDoor Price right now gives you the real-world number - the one that reflects what's actually happening in our market, not what happened two assessment cycles ago.

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

If selling is on your mind, the data is giving you a green light to at least have the conversation. Here's why:

• House values are trending up, not sideways. The 3-month moving average is rising, which means buyers are still paying more than they were a few months ago.
• Unionville sits above average in Markham's growth rankings for both property types. You're not selling in a struggling pocket - you're selling in one of the stronger-performing neighbourhoods in the city.
• Nearby neighbourhoods are cheaper. Buyers who want Unionville can't easily substitute it with Milliken East or Markham Village at the same price point. That scarcity works in your favour.
• Summer inventory typically rises. More competition from other sellers means the window to list while supply is still relatively tight could be right now, not in August.

The market isn't on fire, but it's not taking a breather either. It's steady, it's growing, and Unionville is outperforming most of its neighbours. If you've been sitting on the fence, pull up your HonestDoor Price today and see exactly where you stand before you decide anything.
