Sandstone Valley, Calgary - September 2026 Real Estate Report

Sandstone Valley Real Talk: Your Home Is Worth Less Than the City Thinks

If you have been glancing at your latest city assessment and feeling pretty good about yourself, hold on. The real-world numbers tell a slightly different story right now - and knowing the gap could save you from a costly mistake whether you are buying, selling, or just keeping score.

The Vibe: What Is Actually Happening on Our Streets

Houses - Taking a Breather

Let us be straight with you. The house market in Sandstone Valley is cooling off. The average sale price sits at $574,700 this month - down 8.5% from last month. That is not a cliff, but it is not nothing either. Listings are coming in around $581,633, and homes are selling at about 97.29% of asking price. Translation: buyers are negotiating, and they are winning.

• Average sale price: $574,700 (down 8.5% from last month)
• Average list price: $581,633
• Price per square foot: $371
• Sale-to-list ratio: 97.29% - buyers are paying below ask
• Average days on market: 28 days
• Properties sold this month: 5

Twenty-eight days to sell is slower than nearby Country Hills, where homes are moving in 20 days. That gap matters. When your neighbour's house sits longer, it puts downward pressure on your price too. The HonestDoor predicted value for houses is $614,743 - slightly ahead of the 3-month moving average of $616,820, which is edging down. Not a freefall, but the arrow is pointing the wrong way for sellers right now.

On the leaderboard: Sandstone Valley houses rank 117 out of 238 Calgary neighbourhoods for growth - solidly above average, but not setting the city on fire. Days-on-market ranks 27 out of 82, meaning we are still moving properties at a moderately fast clip compared to most of Calgary. Price rank is 143 out of 220 - below average for the city, which keeps us accessible.

The rental story is genuinely strong though. Estimated rent of $2,990 per month against a predicted value of $614,743 works out to a 5.41% rental yield. For investors, that number is hard to ignore.

Condos - Steady, But Watch the Trend

The condo side of Sandstone Valley is a different animal. Only one unit sold this month at $495,000 - essentially flat from last month. Condos are moving in 18 days on average, which is faster than Country Hills (20 days) but slower than Macewan Glen (9 days). With just one sale, we are working with a thin data set, so take the month-over-month read with a grain of salt.

• Average sale price: $495,000
• Average list price: $499,900
• Price per square foot: $371
• Sale-to-list ratio: 99.02% - very close to full asking price
• Average days on market: 18 days
• Properties sold this month: 1

The HonestDoor predicted value for condos is $422,484, which is dipping slightly from the 3-month average of $424,949. Year-over-year neighbourhood growth for condos is down 0.01% - a small decline, but worth watching. The rental yield on condos comes in at 3.99% with an estimated $2,189 per month in rent. Moderate returns, not spectacular.

Here is a stat worth bragging about though: Sandstone Valley condos rank 32 out of 175 Calgary neighbourhoods by price - putting us among the most expensive condo markets in the city. And on the leaderboard for days on market, we rank 15 out of 75 - that means our condos sell faster than roughly 80% of comparable Calgary neighbourhoods. Demand is real.

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

Here is the thing about your city assessment - it is a snapshot from months ago, built on a formula that does not care what happened on your street last Tuesday. It is not designed to tell you what a buyer will actually pay today.

Right now in Sandstone Valley, the average city assessment for houses sits at $639,056. The average HonestDoor Price is $619,546 - that is a $19,510 gap, and the HonestDoor number is 3.05% lower than the assessed value. For condos, the gap is even wider. The city assessment averages $440,961 while the HonestDoor Price comes in at $414,036 - a difference of $26,925, sitting 6.11% below the assessment.

Why does this matter? If you price your home based on the city assessment, you may be starting the conversation in the wrong place entirely. The HonestDoor Price updates in real time using actual transaction data. It is the number that reflects what buyers are doing right now - not what the city calculated last fall. Think of it as your real-world gut check before you call an agent or set a price.

The condo HonestDoor Price has also slipped 2.00% from the previous period. That is a signal worth paying attention to before you assume your unit held its value.

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

If you are a house owner eyeing a summer sale, the honest answer is: the window is tightening. Prices are down month-over-month, buyers are negotiating below asking, and homes are sitting longer than in some nearby neighbourhoods. That does not mean you should panic - 1,812 properties were assessed here, 64 transactions happened in 2026 already, and Sandstone Valley still outpaces Country Hills, Macewan Glen, and Beddington Heights on neighbourhood growth. We are not a distressed market. But the days of slapping a number on a sign and waiting for a bidding war are on pause.

For condo owners, the picture is more nuanced. You are in one of Calgary's pricier condo markets and your units move fast - but the HonestDoor Price is drifting down and the yearly growth rate just ticked negative. If selling is on your radar, sooner is probably smarter than later.

For anyone staying put, the rental numbers are your friend. A house generating close to $3,006 per month in estimated rent, or a condo pulling $2,152, makes holding a genuinely reasonable strategy while the market finds its footing.

• Thinking of selling a house? Price it sharp - buyers are paying 97 cents on the dollar right now
• Thinking of selling a condo? Move quickly - the trend line is softening
• Holding your property? Rental yields of 5.41% on houses make the wait worthwhile
• Check your HonestDoor Price before you do anything - the city assessment is not your friend in this market

Sandstone Valley is not broken. It is just recalibrating. The neighbourhoods around us are all cheaper and growing slower - that says something real about where we sit in the pecking order. But right now, the market rewards sellers who know their actual numbers, not the ones printed on a government form.
