Your Partner on the Prairie

Cassie Powell

Owner of One Iron Realty | Montana Real Estate Broker

From the Big Flat to the Missouri Breaks—and Everywhere in Between

At One Iron Realty, I'm proud to serve the heart of north-central Montana. From commercial properties and homesteads to farms and ranches, I’m here to help you navigate all your real estate needs with local expertise and a personal touch.

Based in Chinook, the heart of Blaine County, I serve a region built on grit, resilience, and a deep connection to the land. This is where generations of families carved out a living and a legacy—homesteading the prairie, raising cattle in the Breaks, and building tight-knit communities along the Hi-Line. That spirit of independence and hard work is still alive today, and it’s what drives everything I do at One Iron Realty.

Whether you're putting down roots, expanding your operation, or investing in the future, I’m committed to walking alongside you with knowledge, integrity, and true Montana values.

“I'm in love with Montana. For other states I have admiration, respect, recognition, even some affection. But with Montana it is love”

  • "Wonderful agent and incredibly helpful. I just recently purchased a property with Cassie as my agent and the property I purchased came with a lot of challenges that made the sale very difficult and I'm confident that with any other agent the sale would have never gone through. The amount of effort she put in truly went above and beyond."

    -Joe

  • "I had so much fun working with Cassie. She’s passionate about helping her clients and has such a caring heart and positive attitude. Her work ethic is another amazing quality of hers. I couldn’t have been happier with my experience and would recommend Cassie to anyone!"

    -Ali

  • "Cassie was my realtor for the purchase of my first house. She's wonderful to work with and make the "scary" purchase not quite so frightening. We managed to get the property closed on a week earlier than planned with the help of her attention to detail. Cassie is extremely fun and easy to work with 10/10 would suggest her for buying and selling your future property."
