Mayfair, Calgary - September 2026 Real Estate Report

Mayfair, Calgary: Your Home Is Worth More Than the City Thinks - But the Market Is Sending Mixed Signals

The Vibe Right Now

If you've been watching the "For Sale" signs on your street, here's what's actually happening. Mayfair is sitting in an interesting spot - premium prices, but buyers are getting pickier. We saw just 1 house sell recently, down 50% from the month before. That one sale closed at $1,550,000, and the seller got 96.81 cents on every listed dollar. Homes are sitting for about 28 days before moving, which is slower than nearby Kelvin Grove where houses are gone in 16 days. The market isn't falling apart - it's just taking a breather.

Here's the bigger picture for us in Mayfair. There are 157 assessed properties in the neighbourhood, and only 5 transactions happened in all of 2026. That's a thin market. Low volume means one or two sales can swing the numbers hard in either direction. Don't read too much into a single slow month, but don't ignore it either.

• Average sale price (Houses): $1,550,000 - down 0.3% from last month
• Average list price this month: $1,764,450
• Price per square foot: $702
• Sale-to-list ratio: 96.81% - buyers are negotiating below ask
• Average days on market: 28 days
• Total transactions in 2026: 5

The Secret Sauce - Your HonestDoor Price vs. That City Assessment

Here's something every Mayfair homeowner needs to understand right now. The city's average assessed value for homes here is $1,686,073. That number sounds impressive - and it ranks us 7th in all of Calgary for assessed value, which is genuinely elite territory. But that assessment is a snapshot frozen in time. It doesn't know what happened last month. It doesn't know buyers are negotiating harder. It doesn't update when the market shifts.

The HonestDoor Price tells a different story. Right now, the average HonestDoor Price for Mayfair is $1,554,374 - that's 7.81% below the city's assessed figure. It has also dipped 0.96% from the previous period. The predicted market value for houses sits at $1,569,370, which is actually trending up against the 3-month moving average of $1,547,684. So while the city's number is frozen high, the real-world number is more nuanced - slightly softer than the assessment, but showing a quiet upward trend in predicted value.

Think of the HonestDoor Price as the number a serious buyer would actually put on paper today. The assessed value is what the city used to think your home was worth. Those are two very different things, and right now the gap between them is nearly $132,000. That gap matters whether you're selling, refinancing, or just keeping score.

• City average assessed value: $1,686,073 (ranked 7th in Calgary)
• Average HonestDoor Price: $1,554,374 - down 0.96% from last period
• Gap between assessment and HonestDoor Price: approximately $131,699
• Predicted house value (current): $1,569,370
• 3-month moving average: $1,547,684 - predicted value is trending above it
• Neighbourhood growth: 0.04% year over year

The Neighbourhood Leaderboard

Mayfair punches well above its weight in Calgary's rankings. On growth rate, we sit at 27th out of 238 comparable neighbourhoods - that puts us in the top 12% of the city. On price, we rank 18th out of 220 neighbourhoods. That's top-tier. Days on market ranks 27th out of 82, which is middle-of-the-pack for speed but still respectable for a high-price segment.

Now look at who's next door. Bel Aire is the obvious comparison - average HonestDoor Price of $3,291,198 with rental potential of $9,689 per month, but growing at just 0.03% year over year. Kelvin Grove is cheaper at $1,329,441 but actually growing faster at 0.05%. Meadowlark Park is the entry point of the group at $906,822 with flat growth. Mayfair sits right in the middle of this cluster - not the cheapest, not the priciest, but holding its own with a predicted value that's actually higher than Bel Aire's current predicted figure of $1,467,600 for houses.

• Mayfair growth rank: 27 out of 238 Calgary neighbourhoods - top 12%
• Mayfair price rank: 18 out of 220 - top tier
• Bel Aire (nearby): HonestDoor Price $3,291,198 - growing at 0.03%
• Kelvin Grove (nearby): HonestDoor Price $1,329,441 - growing at 0.05%
• Meadowlark Park (nearby): HonestDoor Price $906,822 - growth flat at 0.00%

The So What - Should You Sell This Summer?

If you're thinking about listing this summer, here's the honest read. Mayfair is a premium address in Calgary - top 10 for assessed value, top 12% for growth, and your rental potential at $5,659 per month (or $5,697 estimated for houses) is real money if you ever wanted to hold and rent. The Airbnb angle is also worth knowing - Mayfair ranks 23rd in Calgary for short-term rental potential at around $281 per night.

But the selling conditions right now require a clear head. Buyers are paying about 3.2% below list price on average. Homes are sitting 28 days - longer than Kelvin Grove next door. And there's a meaningful gap between what the city assessed your home at and what a buyer will actually write a cheque for. If you list at or near the assessed value, expect pushback.

The smart move before you call an agent is to pull your HonestDoor Price and use it as your reality check. Price close to where the market actually is - not where the city's frozen assessment says it should be - and you'll move faster and negotiate from a stronger position. Overprice it and you'll be sitting on the market while Kelvin Grove listings get snapped up in 16 days.

Bottom line: Mayfair is still one of Calgary's best addresses. The fundamentals are solid. But this summer rewards sellers who price smart, not sellers who price proud.
