Mark & Kelli Osterman

A real estate team built on design, construction, lending, and marketing expertise

Very few real estate teams can offer expertise in interior design, residential construction, mortgage lending, marketing, and real estate under one roof. Mark and Kelli’s combined experience allows them to evaluate homes from multiple perspectives: how they’re built, how they’re financed, how they’re presented to the market, and how they’ll function for the people who live in them. The result is a more informed, strategic approach that helps their clients make better decisions whether they’re buying, selling, building, or investing.

What our clients say

★★★★★

“Mark and Kelli Osterman helped us sell a home my mother has lived in for the past 50 years. It was a unique 2 acre property on a lake in the middle of OKC. We met several other agents and decided on Mark and Kelli because they understood the uniqueness of the property and had strong marketing ideas. They went above and beyond to get us the most value for our home during this challenging market. During the negotiation processes, their expertise shown through and brought us a higher value than we anticipated. They also had a very kind, compassionate approach to working with my 87 year-old mother and myself. They kept in touch during the entire process. Mark and Kelli handled the process with care, professionalism, and understanding from start to finish. We are truly grateful for their guidance and highly recommend them.”

“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.”

Ryan T., about Mark and KelliClient review

“Kelli was recommended by my new employer to help us in our relocation to Oklahoma. In moving here from out of state, Kelli helped us identify the communities that fit our search criteria, and her organized approach helped us make the most of our short time in locating a home in Edmond that fit our needs. Before our first trip to the state, Kelli set us up with a personal website that identified homes that met our search parameters, which kept track of our favorites and remarks in one easy location, so we were all on the same page once we arrived in town. Kelli is professional and easy to work with, and she helped make the home-buying process a smooth one. She handled all of the details from the initial offer all the way through the final closing on our new home. We would recommend Kelli to others relocating to the Oklahoma City metropolitan area.”

Why this works

Marketing is the part most agents skip

Listing a home puts it in the MLS and waits for someone else to bring a buyer. For a lot of listings, that's where the marketing stops. We put every house in front of thousands of people in the area with a paid ad, and in front of the agents who have sold homes nearby in the last year.

Good to know

Common questions

Will we work with Mark or with Kelli?

Most likely a bit of both. We usually both attend every meeting and walkthrough, so you get all of our expertise in one visit. Then whichever of us fits best with you, your type of home and the expertise needed takes the lead, and the other is always there for backup and support, so your experience is well rounded and you are well represented.

What areas do you cover?

Most of our work is in Edmond and Northwest Oklahoma City, from our home base in downtown Edmond. We also help buyers and sellers across the rest of the OKC metro: Arcadia, Choctaw, Deer Creek, Guthrie, Jones, Midwest City, Moore, Mustang, Nichols Hills, Norman, Oklahoma City, Piedmont, and Yukon.

Do you help buyers with new construction?

Yes. Mark has spent years on the builder side with home builders across the OKC metro, and Kelli has 21 years around new construction. The builder's sales rep works for the builder. We work for you.

Is a home value from you free?

Yes. We call it the Two-Perspective Walkthrough: we both walk through your house, then give you a price range with the reasoning behind it. There's no pressure to do anything with the number.
