The JS Group



James Streff, Founder

Always having a passion for everything ‘Chicago’, I decided to pursue a career in residential real estate after receiving a degree in finance from The University of Iowa. Growing up on Chicago’s northwest side, in the Jefferson Park neighborhood, I have spent my life exploring and getting to know the neighborhoods of the city. Chicago is such a unique city and offers so much to people, and there’s nothing I enjoy more than being able to show and sell homes throughout the city. Since becoming a broker in 2012 after learning the industry as an unlicensed assistant for one year before that, I have closed over $100 million in sales and continue to grow each year. I attribute this success to the long-lasting relationships I have created with past clients and am honored to have built my business almost exclusively on client referrals. What sets me apart is my commitment to clear and consistent communication. I make myself available to clients at all times and am dedicated to remaining responsive and reliable.

I pride myself on taking an analytical approach to real estate. Through constant market surveillance I am able to provide clients with a wealth of up to date knowledge regarding home sales and market value in their area, leading to a personalized strategy for each client. I specialize in condo and single family home sales throughout the city and Chicago’s North Shore, and regularly work with first time buyers, sellers & investors.

Having previously lived in Jefferson Park & Roscoe Village, I currently reside in Logan Square with my wife, our sons Everett & Hudson, and our two cats Rosa and Halloween.


Michael Tye, Broker

A lifelong Chicagoan, Michael grew up in the northern suburbs of Chicago, migrated to Evanston and now lives on the north side of the city with his wife, Children, Leo and Olive and their dog, Daisy. Michael worked in banking on the north shore for 10 years and in the construction industry for three. It is this unique blend of experiences that Michael leverages for the benefit of his clients; understanding both the financial aspects of buying or selling a home as well as the repair, maintenance, and construction that goes into them.

He is a true believer in the power of great customer service and it is at the heart of everything he does as a Realtor. Whether personally or professionally, Michael wishes to build meaningful relationships with those he comes in contact with. It’s for this reason that being a Realtor was such a natural fit for him. Michael loves meeting new people, learning of their stories and helping them in any way he can.

When not working he enjoys both playing and watching sports, spending time with his family and visiting the many fantastic eateries that Chicago has to offer.
