If you've been watching the "For Sale" signs on your block and wondering what's actually going on, here's the straight story. Marlborough is holding its own in a city where every neighbourhood is fighting for position. Prices are up, homes are moving, and the gap between what the city assessed your property at and what it's actually worth right now is something every homeowner here needs to pay attention to.
Let's break down what's happening for us on both sides of the market.
The house market in Marlborough is showing real momentum. Average sale prices hit $580,167 this period - that's up 5.4% from last month. Six homes sold, and they averaged 35 days on market before finding a buyer. That's not lightning fast, but it's not sitting either.
The combination of affordable entry prices and a 5.60% rental yield is worth noting. If we're thinking about this as an investment, Marlborough houses are punching above their weight class.
The condo side of Marlborough is a different story - smaller numbers, but still active. One condo sold at $263,750, which is actually above what sold recently in nearby Forest Heights ($250,000). Properties are clearing in 28 days on average, which is genuinely quick.
The condo HonestDoor Price of $291,964 is sitting 10.07% below the city's assessed value of $320,111. That gap matters - and we'll explain exactly why below.
Here's the thing about your city assessment - it's a snapshot from the past. The city looks at sale data from a prior period, runs it through their formula, and mails you a number. By the time it lands in your mailbox, the market has already moved on.
The HonestDoor Price is updated in real time. It pulls from current sales, current listing activity, and current market signals. For Marlborough houses, the HonestDoor Price sits at $518,971 - just 0.35% below the city's average assessed value of $520,797. That's actually a pretty tight match, which tells us the city got reasonably close this time around for houses.
Condos are a different story. The city assessed condos here at an average of $320,111. The HonestDoor Price says $287,887. That's a $32,000 gap - and it's not in your favour if you're a condo owner paying property taxes based on a number that's 10.07% higher than what the real market says your unit is worth. That's the kind of discrepancy that's worth challenging.
Bottom line: don't wait for next year's assessment letter to find out where you stand. Check your HonestDoor Price now. It's the real-world check against a number the city set months ago.
If you're a Marlborough homeowner weighing a summer sale, here's what the data is actually telling you.
For house sellers, the timing is decent. Prices are up 5.4% month over month, the predicted market value of $518,481 is climbing above its 3-month average, and buyers are paying 98.17% of list price. You're not going to get a bidding war frenzy, but you're also not going to be sitting on the market for months. With 94 total transactions recorded in 2026 and Marlborough ranking 46th in Calgary for total transaction volume, there's real buyer activity in this neighbourhood.
For condo sellers, be realistic about pricing. The sold-to-list ratio of 94.23% means buyers are negotiating. List sharp, price close to the HonestDoor Price of $291,964, and you'll move faster. The 28-day average days on market backs that up - correctly priced condos here are not collecting dust.
One more thing to keep in mind: Marlborough sits in a competitive spot relative to its neighbours. Marlborough Park condos are averaging $499,421 for houses and $260,020 for condos - both cheaper than us. Franklin is significantly higher priced at $691,967 for houses. We're in the middle of the pack on price, which actually works in a seller's favour - buyers who get priced out of Franklin look at Marlborough next.
The neighbourhood growth rate of 0.01% year over year for houses is modest - this market is taking a breather on appreciation. But with a rental yield of 5.60% and real buyer demand, Marlborough is still a smart place to own. If selling is on your mind, this summer is a reasonable window - just price it right from day one.
