About Mark Osterman | Mark and Kelli Osterman

Mark Osterman

Mark didn't stumble into real estate; he built his way into it. He began his career in the mortgage industry, giving him a ground-level understanding of how real estate transactions are financed and what actually makes a deal work from the financial side. From there, he moved to the builder side, spending years working directly with one of Oklahoma's top home builders, where he learned what goes into building a home: the decisions made before a buyer ever walks through the door, the construction behind the walls, and the details that determine long-term value. This foundation alone sets him apart from most agents, who only ever see a transaction from one side.

After earning his real estate license, he continued working with new construction builders, but his experience spans far beyond that. Mark holds a Bachelor's degree in Marketing and a Bachelor's degree in Management, and he brings both into how he approaches real estate. He understands how to position a property, how to communicate its value, and how to manage the moving parts of a transaction with precision, a combination of skills that make a measurable difference for his clients on both sides of the deal. Whether a client is building from the ground up, purchasing an existing home, or navigating a sale, Mark brings the same depth of knowledge and attention to detail to every transaction. And his approach is straightforward: integrity first, every time.

Mark works alongside his wife, Kelli, who is a licensed REALTOR® with over fifteen years of real estate experience and a background in interior design. Together, they bring over 30 years of combined real estate experience. You work with one of them, you unlock the collective depth of both. Each brings the full power of the partnership to the table.

Success Stories

"We loved working with Mark and Kelli. Mark sold us the house and knew every detail of the house, so it was a no-brainer when we asked them to list and sell our house. They are truly honest agents, and they go above and beyond what an agent's duties are supposed to be. If opportunities arise in the future, we would definitely work with them!"

Seller

"Mark did an excellent job helping us pinpoint a residence in the area we were interested in. He was very helpful during the negotiation process and finally with the closing on our house. All in all, an excellent job. Thanks, Mark!"

Buyer

"This couple was absolutely amazing! They helped my boyfriend and me find the perfect home. They helped us look for issues we were concerned about in houses, and they were very friendly! I almost want to buy another house to go house hunting with them again! Too bad the house we found is perfect."

Buyer

"Mark and Kelli assisted my wife and me in finding our new home in Edmond, Oklahoma. We were from out of town, but visited regularly during the search process. In the beginning, Mark and Kelli took the time to understand our housing needs and wants, and provided appropriate advice to make our search more efficient. They were flexible in schedule and most responsive. As experienced buyers, my wife and I had high expectations, and Mark and Kelli delivered. They combine outstanding knowledge of the market, neighborhoods, and builders, with the utmost professionalism and integrity. Mark even provided factual considerations on building quality and efficiency. They were also a pleasure to be around and reduced the stress of the overall process. Needless to say, my wife and I plan to refer colleagues, friends, and family."
