About
Chicago's Responsive Property Manager® After 23+ years as a real estate investor and property manager, we've made every mistake in the book, so you don't have to. That hard-won experience now guides over 1,200 investment properties across the Chicago metro area. Today's landlord landscape is more complex than ever: shifting local ordinances, fraudulent tenant schemes, squatter issues, and rising resident expectations. We stay ahead of it all. Our team actively tracks Cook County and Illinois regulatory changes so your investment stays compliant and protected. What sets us apart: -100% Local Focus – Our office is centrally located in Roselle, and we only manage properties in Chicagoland. We know these neighborhoods, municipalities, and their quirks. -In-House Maintenance – We control quality and cost with our own maintenance team, critical as labor and materials have climbed since 2020. Technology + Human Touch! We use AI to streamline back-office operations so our team can focus on what matters: real relationships with residents, clients, and vendors. -A+ BBB Rating – Our reputation speaks for itself. We encourage you to interview multiple firms, just make sure we're one of them. And if you want to learn more about Chicago real estate investing, check out our podcast, Straight Up Chicago Investor. Mark Ainley, Partner/Founder P.S. If we're not the right fit for your property, we'll tell you, and connect you with a manager who is.

I hired GC Realty to manage my property, and so far, the experience has been great. They are extremely communicative, and they are working to fill my property quickly. I highly recommend them.

I just started working with Mark after he replied to my request on Thumbtack. His thoroughness, knowledge and overall demeanor sold me. He will be helping me rent my property, and then if all goes well, GC Realty will be managing my property for me moving forward. Excited to be working with them!
