How we work

From our family to yours.

Real estate decisions are personal. Our job is to make the process clearer, more strategic, and better managed from the first conversation through closing.

01

Advice grounded in the market

We use local transaction experience, comparable sales, current competition, market data, and property-level analysis to help clients make decisions with context rather than guesswork.

02

A team with complementary strengths

Our principals bring different areas of expertise across brokerage leadership, negotiation, market statistics, transaction management, industry policy, and client representation.

03

Hands-on representation

We remain directly involved in strategy, communication, negotiation, and execution. Clients are not passed through a large production line or left wondering who is responsible for the next step.

The people behind the work

What our experience means

Depth that extends beyond a transaction count.

Experience is most useful when it improves judgment: how to price, when to push, when to pause, how to evaluate risk, and how to keep a complicated transaction moving.

Since 2008, The Thayer Group has completed more than 780 residential transaction sides representing more than $412 million in recorded closed sales volume across Colorado. Our public transaction record currently includes 726 transaction sides verified against MLS records. Our work spans first-time buyers, growing households, move-up clients, luxury properties, new construction, investment real estate, relocations, divorce-related sales, estates and inheritance, and sellers navigating complex timing or property conditions.

We are based in Castle Rock and affiliated with Keller Williams Action Realty. Our primary footprint includes Castle Rock, The Meadows, Douglas County, Parker, Highlands Ranch, Castle Pines, Lone Tree, Larkspur, the Denver Metro area, and Colorado Springs, with completed transactions extending across 36+ Colorado communities.

The breadth of that transaction history gives our team perspective across different market conditions, price points, property types, and negotiation environments. Clients benefit from that experience at the moments where judgment and execution matter most.

Who we work with

Real estate expertise for different stages of life and ownership.

Our practice is intentionally broad, with dedicated experience in several transaction types that require more specialized guidance.

Buyers

First-time and experienced homebuyers

Education, property analysis, offer strategy, due diligence, and transaction management from initial planning through closing.

Sellers

Homeowners preparing to sell

Pricing, preparation, positioning, marketing, showing strategy, offer analysis, negotiation, and closing coordination.

Move-up

Clients buying and selling together

Coordinated timing, financing considerations, contingency strategy, and transaction planning when two moves need to work together.

Luxury

High-end buyers and sellers

Representation for luxury properties requiring careful positioning, discretion, sophisticated marketing, and detailed negotiation.

Relocation

Out-of-state buyers and sellers

Boots-on-the-ground support for clients managing a Colorado transaction from another state, including property access, vendors, inspections, and logistics.

Copper is not only a knowledgeable number guru when it comes to real estate but a true professional. He’s keeps you informed, knows the market and gets results! Call him!

Jeff Story

The Thayer group did a outstanding job walking us through everything we needed to do to sell our home in Castle Rock. Steve and Susan were very very helpful with guiding us with their knowledge of buyers on what they liked and did not like to get our home ready for listing. They spent a lot of prep time well before listing the home. I would 100% recommend Steve, Susan And Cooper to anyone looking to list their home and getting a very personable agent with a abundance of knowledge about the Castle Rock area. 10 Stars

Kyle Browning

I had a fantastic experience working with The Thayer Group to sell my home in Denver. From start to finish, they were incredibly helpful, responsive, and communicative. I always felt informed about what was happening and knew what to expect throughout the process. Whenever a question or challenge came up, the team was quick to find a solution and kept everything moving forward. They made what can be a stressful process feel smooth and manageable, and I truly felt like I had knowledgeable and dependable partners in my corner every step of the way. I couldn’t recommend The Thayer Group more highly to anyone looking to buy or sell a home. They’re professional, proactive, easy to work with, and genuinely invested in making the experience a positive one. Five stars!

Cherese

When selling our home, we wanted realtor representation that was knowledgeable, professional, and the best in the area. The Thayer Group was not only awarded “The Best of The Best” #1 team in the area, but they brought their heart and soul to a process that could have easily felt like a simple transaction. They are true professionals with extensive market expertise, unparalleled go-get-it-ness, and the highest level of integrity! Selling was expedient and closing was carefree. Huge thanks to The Thayer Group!!!

Colm Smart

Steve knows Castle Rock real estate and is excellent in brokering the best deal for everyone. He sold our house in a day and the negotiation process was painless. Thanks Steve.

Valerie Montano

They are the best in the business. We were so lucky to have them!

Amazing realtor!

Jeff Childers

My wife and I have partnered with The Thayer group to purchase and sell a home. We couldn't recommend them more. They are thorough & professional and do what they say they will do. We really appreciate the advice that they gave us throughout the entire process, both selling and purchasing. And, even more importantly, they are fun to work with. Genuinely nice people, who care about their clients.

richard blair

Working with the Thayers was fantastic! They made buying\selling our home stress-free, answered every question we had, and were always easy to reach. We couldn’t have asked for a better experience and highly recommend them to anyone.

Brian L

The Thayer group has been responsive & professional. Thanks.

Andrew Gallegos

I recently had the opportunity to work with Steve Thayer and The Thayer Group on a transaction where they represented the seller and I was the buyer’s lender. As a lender, you don’t always get a clear picture of how well the listing side is handling a transaction, but in this case, it was easy to see that Steve and his team are great at what they do. They were communicative, proactive, helpful throughout the process, and clearly worked hard to make sure their sellers were well represented and that we had a smooth, on-time closing. It was a pleasure working with Steve and his team, and I would highly recommend The Thayer Group to anyone looking to buy or sell a home.

Frank Sanford

Excellent experience working with the Thayer Group. They got the house sold for top dollar, in a matter of days, for $100,000 more than competing Realtors had predicted! Research them, and you'll see that they're the top Realtors in their area of Colorado. Look forward to working with them again.

Sandra

The Thayer Group dramatically reduced the stress of selling our home. Their excellent advice, quick response time and great communication enabled us to list, sell and close in less than 30 days. It was our pleasure to work with all of them.

max

(Responding back to business) Yes we have worked together (Cooper). Just because I made 2 reviews locally (5 stars for a food place i ate at) doesn’t mean yours is a mistake. Weird you assume that first thing. This reaffirms my 1 star rating with your response and entitled assumptions.

Gabriele Ostrowicki

Susan Thayer was my realtor for the purchase of a beautiful home in Denver’s LoHi district, and I couldn't be happier with the experience. From our first contact, I felt completely at ease. She worked diligently with my daughter and me even before we arrived in Denver, preparing an excellent list of properties for the few days we were in town. She picked us up promptly from our vacation rental and was incredibly knowledgeable, showing us all the neighborhoods we were interested in. We eventually settled on a property that was a perfect fit for us, and she walked us through every step of the process. Her husband, Steve, and son, Cooper, were also part of the team; they guided us through determining the right offer price, making the entire experience feel effortless. They provided great recommendations for home inspectors and closing agents, and the whole family went above and beyond—they even got us measurements we needed before closing. The entire process was seamless, and I truly enjoyed getting to know Susan and Steve. We found the perfect agent and had the support of their whole family throughout the purchase. We found our "gem," and it was such a pleasure to be in such competent hands. I highly recommend them to anyone looking for a home!

Maureen Lesak

Fantastic, very knowledgeable and deal-savvy group, had full confidence in them at every step of the way. Very grateful to have connected with this team in the beginning of my search! While I hope not to move again for a while, I definitely look forward to working with the Thayer team in the future!

Becky Kuzma

We loved the professionalism and straightforwardness of this family. They were so easy to work with and delivered everything they said they would. We'll definitely work with them again in the future.

P K

What an outstanding Team! Every part of the selling process was super easy, because they are very personable, professional, and knowledgeable. Hands down, they are the go-to Realtors for any real estate transaction. Thanks again!

William Schmitz

Cooper was awesome to work with! He was super responsive, always available when we had questions, and made the entire home-buying process so much easier. We really appreciated his guidance and support every step of the way. I’d recommend him to anyone looking for a great real estate agent.
