Agent Details

Meet Jason

Jason Cox loves working with his clients to connect them to their dream homes across the city and Northshore.

Jason understands the importance of building relationships with his clients and credits these meaningful connections and his client-focused approach for his real estate success. Ever resourceful, Jason’s meticulous attention to detail and unmatched local knowledge offers his clients the tools and expertise they need to navigate the process with ease. Jason is a relentless advocate for his clients and knows that it’s more than just buying or selling a home his clients are looking for a place to establish themselves and grow, a responsibility he takes very seriously. Jason utilizes the latest technology, data, and cutting-edge marketing strategies to ensure his client's real estate goals are always met.

As a seller, you can count on Jason’s knowledge of the market to help you maximize your investment. His interior design skills help his clients skillfully stage their spaces to present their property to the market in the best possible light.

As a buyer you can credit Jason’s ability to confidently negotiate the best price for you and guide you through the buying process, making sure you are aware of the condition and value before you submit an offer. His approach has been to create a long-term relationship with his clients, so they can feel they have an advocate and adviser for years after the closing.

Prior to becoming a broker, Jason worked in interior design where he developed his passion for creating beautiful spaces. Over the course of his career, he found himself drawn more and more to the real estate industry and transitioned into real estate sales where he can combine both passions. His keen sense of design and market expertise affords his clients a unique opportunity as they enter their home journey.

Jason loves living in Chicago and enjoys spending his free time exploring the city and Northshore. He is always on the hunt for the next great culinary experience or taking in the beauty of the lakefront.
