Mark from CIC was an excellent speaker—knowledgeable, engaging, and very practical. He shared valuable real-world insights and explained everything in a clear and easy-to-understand way. I really enjoyed the presentation and learned a lot. Highly recommend attending any event where Mark is speaking!

I can’t say enough good things about GC Realty and the level of service we’ve received. Throughout the entire process, they were responsive, professional, and genuinely cared about helping us. Every question or concern we had was handled quickly, and they always kept us informed. I especially want to recognize Shania Gilharry. She went above and beyond to help my family with every issue that came up. Whether it was resolving a maintenance chargeback, helping with account questions, or finding solutions that worked for us, she was always patient, kind, and proactive. It truly felt like she was advocating for us every step of the way. Excellent customer service is hard to find these days, but Shania made the entire experience stress-free. If you’re looking for a property management company that genuinely cares about its residents, I highly recommend GC Realty. Thank you again, Shania, for everything you’ve done for our family!

I connected with Mark from GC Realty recently, and he has been fantastic to deal with. He is incredibly knowledgeable about the Chicago market, highly professional, and quick to follow up. When I asked him for some resources, he personally emailed them over right away. It’s rare to find that level of responsiveness and genuine helpfulness. If you’re looking for a solid, reliable team to work with, GC Realty is top-tier!

11 months of leaks, bandaid fixes, and incompetence. Two separate leak issues were never fully resolved. Two flooding incidents left over 5 inches of standing water for over a week. Videos attached. Avoid GC Realty.

My fiancé and I were looking to move to a nicer area in Chicago and luckily we came across a listing posted by GC Realty & Development, LLC. Booking a tour was done quickly and professionally. We got to view the apartment and were both happy with the experience, so we decided to submit an application. I got to work with Catherine Quiroz throughout the application process and she was amazing! She is very professional and helpful, answered all my questions right away and made things clear and easy for us. We were very happy and satisfied with her service! Thank you!
