Diamond Valley Realtor: Buying and Selling Homes in Diamond Valley, Alberta
Updated October 30, 2026 · Written by Justin Warthe, Team Lead, The Top Calgary Real Estate Team
Diamond Valley is the town formed in 2023 when Black Diamond and Turner Valley amalgamated, 45 to 50 minutes southwest of Calgary on Highway 22, the Cowboy Trail. It is the gateway to Kananaskis and the Sheep River valley, with two historic main streets, a golf course, the Oilfields hospital and the acreage country of Millarville and Priddis next door. If you are looking for a Diamond Valley realtor, here is how we work and what to expect.
Quick answer: Yes. The Top Calgary Real Estate Team lists and sells homes and acreages in Diamond Valley and represents buyers moving there from Calgary and Okotoks. We are a 10-REALTOR® team brokered by Real Broker with 179 five-star Google reviews and more than $1 billion sold across Calgary and area. Call or text 403-620-8746 or book a call for a free Diamond Valley home evaluation or buyer consultation.
Key takeaways
- Diamond Valley does not get its own CREB® benchmark. Okotoks ($606,800) and High River ($495,000) are the nearest reference points, and Diamond Valley homes generally sit between or below them depending on age and lot.
- This is a lifestyle market: buyers come for the mountains, the river, the trails, the small-town main streets and the acreages, and they are willing to drive for it.
- Acreages around Millarville, Priddis and the Sheep River are a large part of the local market and need rural expertise: wells, septic, county zoning and road access.
- Most Diamond Valley buyers are comparing it with Okotoks and High River, and with Bragg Creek on the other side of the foothills. We work all of them.

What is different about buying and selling in Diamond Valley
Diamond Valley is small, and so is its sales volume, which makes pricing harder than in a big market. A handful of sales can swing a monthly average. Our evaluations go back further, separate townsite homes from acreages, and adjust for age, lot and view rather than relying on a thin monthly number.
The buyer is driving for a reason. Kananaskis trailheads, the Sheep River, the Cowboy Trail, the Oilfields history, the golf course and a quieter pace are the product; the house is only part of it. Listings that sell the setting outperform those that do not.
Acreages are a market of their own. Water wells, septic systems, Foothills County land-use rules, road maintenance and internet options all affect value and financing. One of our REALTORS® holds a rural licence, and we build those checks into every rural purchase.
