Williamstown, Airdrie - September 2026 Real Estate Report

Williamstown, Airdrie: Your Neighbour Just Got a Surprise - Here's What the Numbers Actually Say

The Vibe Right Now

If you've been watching the "For Sale" signs on your street, here's what's actually happening. Williamstown is sending mixed signals depending on what you own. Houses and condos are telling two very different stories this month, and knowing which one applies to you could be worth tens of thousands of dollars.

Houses - Strong Prices, But Buyers Are Taking Their Time

The average sale price for houses in Williamstown hit $546,120 this month - up 21.9% from last month. That's a number worth reading twice. Listings are sitting at $569,333 on average, and homes are selling at 96.65% of list price, so buyers are getting a small discount but not a big one. At $344 per square foot, we're holding our own in the Airdrie market.

The catch? Homes are sitting for 30 days on average before selling. Compare that to Silver Creek where houses are moving in 15 days, and it's clear our market is taking a bit of a breather. Ten houses sold this month, which puts us at rank 10 out of all Airdrie neighbourhoods for total transactions - that's actually a strong showing for activity.

• Average sale price: $546,120 (up 21.9% from last month)
• Average list price: $569,333
• Price per square foot: $344
• Sale-to-list ratio: 96.65%
• Average days on market: 30
• Properties sold this month: 10
• Rental yield: 5.50%
• Estimated monthly rent: $2,788
• Growth rank: 42 out of 48 neighbourhoods in Airdrie

That growth rank is the one number to watch. On the neighbourhood leaderboard for price growth, houses in Williamstown sit near the bottom - 42nd out of 48. Prices are not falling off a cliff, but we are not leading the pack either. The predicted market value sits at $569,158, which is barely budging from the 3-month average of $569,149. Steady, but not surging.

Condos - A Surprise Bright Spot

Here's where it gets interesting. Condo owners in Williamstown are sitting on something quietly valuable. The predicted market value for condos is $401,093 - well above the 3-month average of $376,308. That's real upward movement. And on the neighbourhood leaderboard, condos rank 5th out of 40 in Airdrie for growth. That puts us near the top of the pack.

Only one condo sold this month, so the sample is thin. But that unit sold at 97.26% of list price in 15 days, which is a clean, stable transaction. The HonestDoor Price for condos is $379,579, though it has dipped 5.36% from the previous period. The predicted value of $401,093 suggests the market sees more upside ahead than that dip implies.

• Average sale price: $355,000
• Average list price: $365,000
• Price per square foot: $243
• Sale-to-list ratio: 97.26%
• Average days on market: 15
• HonestDoor Price: $379,579 (down 5.36% from previous period)
• Predicted market value: $401,093
• Rental yield: 4.02%
• Estimated monthly rent: $2,089
• Growth rank: 5 out of 40 neighbourhoods in Airdrie

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 months ago, sometimes longer. It doesn't know that house prices in Williamstown jumped 21.9% last month. It doesn't know that condo predicted values are climbing toward $401,000. It's working with old film in a digital world.

The HonestDoor Price is updated in real time using actual transaction data, current listings, and live market signals. For houses, that number sits at $577,332 right now - up 1.44% from the previous period. For condos, it's $379,579. These are the numbers a buyer's agent is looking at when they walk through your door. Your tax assessment is not.

If you're a house owner in Williamstown, your HonestDoor Price is already $31,000 higher than the average sale price this month. That gap is your negotiating room. If you own a condo, the predicted value of $401,093 is sitting $21,000 above the current HonestDoor Price - which suggests the market is pricing in more growth ahead. Either way, checking your HonestDoor Price today costs nothing and could reframe every conversation you have about your property.

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

For house sellers, the timing question is real. Prices are up sharply month-over-month, but homes are taking 30 days to move and the growth rank is near the bottom of the Airdrie leaderboard. That combination means you can still get a strong price - but you need to list smart. Price it right from day one. Buyers in Williamstown are paying 96.65% of list, not 100%. They have options and they know it.

For condo sellers, the story is more encouraging. You're in a top-5 growth neighbourhood for condos in all of Airdrie. The predicted value is rising. If you've been sitting on the fence, this summer is worth a serious look. One condo sold this month - if yours is the only one on the market, you control the conversation.

For anyone thinking about renting instead of selling, the numbers hold up. A 5.50% rental yield on a house is genuinely strong. At $2,825 per month in estimated rent, Williamstown is competitive with every nearby neighbourhood - above Silver Creek at $2,661 and within reach of Reunion at $2,979.

Bottom line - Williamstown is not a market to ignore right now. It's also not a market to walk into without knowing your real numbers. Check your HonestDoor Price, compare it to what's actually selling on your street, and make your move with real data in hand.
