We knew what we wanted and TJ knew how to make it happen, and we did it. He constantly kept us informed of what was needed and when, where we were in the process, and advocated for our success every step of the way.

TJ was awesome to work with and found us the perfect place! He knew exactly what we were looking for and delivered. He was very easy to work with through the whole process and was happy to help us navigate the entire process. Very smooth and seamless from showing to negotiation to closing. Highly recommend TJ for helping you find your next home!

As a first-time homebuyer, working with Noell was an absolute blessing. From our initial conversations to the moment I held the keys to my new home, she provided unwavering guidance and support every step of the way. Noell took the time to clearly explain each phase of the homebuying process, offering thoughtful insights into neighborhoods and listings, and expertly breaking down the nuances of crafting competitive offers. Her professionalism was matched by her genuine patience, especially as I navigated moments of indecision and hesitation. No matter the question or concern, Noell was always quick to respond with clarity and encouragement. Thanks to her deep expertise and steady support, what could have been a stressful experience turned into a smooth, exciting journey. I am deeply grateful for Noells dedication, warmth, and sharp real estate acumen. She didn't just help me buy a condo - she helped me find the place I will now call home.

Clay was the best agent I could hope for, he helped with all aspects of the process with lots of guidance, advise and availability to respond to urgent matters. He has many contacts in the real estate world and used them to make the process of selecting people for different tasks a lot easier I was impressed how much he listened to my needs and knew exactly how to help me with the selection of the area and the house itself I would recommend Clay ?? % as your agent and will use his services and expertise again when I need to deal with real estate

I recently bought a condo in Snohomish and had the pleasure of working with Clay Cook as my realtor. He made the entire process smooth and stress free. He was always there to answer any questions I had along the way. His expertise in the market and attention to detail really stood out. I would highly recommend Clay to anyone looking to buy or sell!
