Thanks Courtney! It was great to work with you and your wonderful family!
As a real estate developer, I’ve worked with many agents over the years, none are as easy to deal with as John and team. Most real estate agents are useless door openers, but John is truly a rare breed. True fiduciary! Cares about his clients and will actually hustle to get a deal done. Thank you John. I will recommend you to my friends and family.
Thank you for trusting us with your business!

Thanks Max! Appreciate you!
I would give more than 5 stars if possible. John and his team were amazing. Great communication all around. We had a tricky situation of buying and selling at the same time, and the expertise and knowledge of the entire team was above expectation. I would not hesitate to recommend him for any buying or selling needs.
Thanks for trusting us to help you Brandon!
John is one of the best realtors in Chicagoland and made our home buying experience super easy and relaxed. He was extremely knowledgeable about the market and was able to explain it to first time homebuyers in a thoughtful and digestible way. He quickly captured our style preferences and was able to provide recommendations and neighborhoods we were missing. He had a wealth of contacts for us when it came to getting mortgage, insurance, and inspection services. Overall, he helped us make our decision that my wife and I are very happy about and we can’t thank him enough for putting us in the right situation. John is a great realtor, especially for first time homebuyers!
Thank you Brian! It was such a pleasure working with you and Shannon.
The best!! Look no further for an unbelievable agent. We seriously couldn’t have asked for a better experience with John Sintich and his team. John truly went above and beyond for us from start to finish and made the whole process of buying our home so much easier than we expected. He was always there for us, whether it was answering questions late at night, getting back to us right away, or even rearranging his own schedule to work around ours. We always felt like we were a priority and never just another client. John genuinely cared about finding the right home for our family and making sure everything went as smoothly as possible. We’re extremely grateful for everything he and his team did for us and would recommend them to anyone looking to buy or sell a home!
Thanks for trusting us to help you. It was such a pleasure to work with you. Congrats on your new home!
We had such a great experience working with John! He was honest, knowledgeable, and incredibly flexible throughout the entire process. We always felt like he had our best interests in mind and never pressured us into making a decision. Most importantly, he helped us find and get the house we really wanted. We couldn’t be happier and would absolutely recommend John to anyone looking for a realtor!
Thanks so much for trusting me to help you! Congrats on your new home!
I recently shared the pleasure of working with John to purchase a home. He is incredibly knowledgeable, professional, and I couldn't recommend him enough. From the beginning of the homebuying process, all the way through closing, John was there to answer any questions and help move along the process seamlessly. John, his team, and his network of professionals were some of the best I've dealt with in the homebuying process. i am looking forward to many more interactions in the future.
Thanks Jim, it was so great working with you. I’m glad we could help you!!
John was exceptional throughout both the sale of our home and the purchase of our new one. He’s incredibly knowledgeable and truly knows the ins and outs of the real estate business. What sets him apart is his honesty—he doesn’t just tell you what you want to hear; he gives you the advice you need to hear and always has your best interests in mind. We always felt confident knowing he was looking out for us. We highly recommend John to anyone buying or selling a home!
Thank you for trusting us to help you sell and buy your home. It was great working with you and your family! Congrats!
