If you own a house in 12 L, the numbers are moving in your favour. The average HonestDoor Price sits at $1,147,443 - up 7.44% from the previous period. That is not a small bump. On the predicted market value side, houses are tracking at $1,067,957, which is already climbing past the 3-month moving average of $1,055,971. The trend line is pointing up, and it has been doing so consistently.
We are also sitting at a 3.08% recent value change, which puts us at rank 33 out of 233 comparable neighbourhoods in Calgary. To put that plainly - 12 L is outpacing roughly 86% of the city right now. That is a leaderboard position worth paying attention to.
For anyone thinking about the income side of things, 12 L holds up well. The average rental estimate is $4,478 per month, with a rental yield of 4.75%. That is considered moderate - not a cash-flow goldmine, but solid and stable for a neighbourhood at this price point. If you are curious about short-term rentals, the Airbnb estimate comes in at $223 per night, with a Calgary Airbnb rank of 68. There is real demand here.
Context matters. Here is a quick look at what is happening around us.
12 L sits in a strong middle ground. We are not the entry-level option, and we are not the top-dollar stretch either. For buyers, that is an attractive position. For sellers, it means there is a real, active pool of people who can afford this neighbourhood and are looking here specifically.
Here is the honest truth about city assessments: they are backward-looking. The City of Calgary calculates your assessed value based on data that can be 12 to 18 months old by the time it lands in your mailbox. A lot can change in that time - and in 12 L, it clearly has.
The HonestDoor Price is updated in real time using current sales data, market trends, and neighbourhood-level signals. Right now, that number is $1,147,443 - and it has moved 7.44% upward. If you are still mentally anchoring to last year's assessment, you are likely undervaluing your own home by a meaningful margin. That gap between the static government number and the live HonestDoor Price? That is real money sitting on the table.
Check your HonestDoor Price today. It takes about 30 seconds, and it gives you the real-world picture - not a snapshot from a year ago.
If you have been on the fence, here is what the data is telling you. Values are up. The neighbourhood is ranked in the top 15% in Calgary for growth. The predicted market value is rising above its own 3-month average, which signals continued momentum - not a plateau.
Summer is historically when buyer activity picks up in Calgary. Combine that with a 7.44% price increase and a top-33 growth ranking, and the case for listing this season is genuinely strong. You are not selling into a soft market. You are selling into a neighbourhood that buyers are actively choosing.
The one thing to do before you call an agent? Pull your HonestDoor Price. Know your number. Walk into that conversation with current data, not a year-old assessment. That is how you negotiate from a position of strength.
