Real Estate Representation

Different real estate decisions require different kinds of expertise.

Buying or selling a home is rarely just about finding a property or putting one on the market. Our team helps clients evaluate the numbers, understand the market, manage risk, negotiate strategically, and coordinate the details from the first conversation through closing.

01

Buying a Home

Search with context, not just filters. We help buyers compare neighborhoods and properties, evaluate value, structure offers, navigate inspections and appraisal, negotiate effectively, and understand the tradeoffs behind each decision.

02

Selling a Home

A successful sale starts before the property reaches the market. We help sellers evaluate pricing, preparation, positioning, marketing, showing strategy, offers, negotiation, and the decisions that affect both timing and net proceeds.

    (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.

    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!

    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.

    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.

    Brianna Schmitz

    Cooper was a phenomenal agent to work with! He is super knowledgeable about the market, incredibly responsive and helped us find our perfect home. I’d recommend him and The Thayer Group to anyone who’s looking to buy or sell!

    Ryan Nicholas

    Cooper and the team took great care of my good friends who I referred to them from here in Virginia, and found them a wonderful home at a great price in the perfect timing that they wanted. As a career Realtor, I know a lot of Realtors in the area, including my Aunt Dana Cottrell who is the President of the Colorado Association of Realtors. So before referring them to an agent I already knew, I knew nobody would have a better recommendation than Aunt Dana! She said Cooper was the right agent to work with them, and that turned out to be true. Can't go wrong working with these guys, they have a stellar reputation!

    Victor Day

    Steve Thayer is a vey friendly and knowledgeable real estate agent. He is honest and extremely helpful. I cannot recommend him too highly.

    Caitlin Harness

    We have had an amazing experience with the Thayer Group! We listed our home with them and it sold in a weekend! Not only did we have great communication, but loved their family dynamic. Each member of this team has been so helpful and exceeded our expectations. They made our home sell, which could have been very stressful, stress free from start to finish.
