Mark Rantis Broker
When Mark Rantis helped his father transition into senior living, he quickly realized how overwhelming and fragmented the process was for families. That personal experience sparked a mission: to become the go-to resource—“the Google and Easy button”—for families navigating the emotional and logistical challenges of senior transitions.
Today, Rantis is a leading expert and trusted advocate in the aging community. He serves on the board of the Illinois Continuity of Care, a nonprofit that supports professionals serving seniors and their families statewide. He also contributes to I Just Need, a nonprofit connecting veterans with housing and essential resources. His deep involvement in these organizations reflects his commitment to being of service far beyond the real estate transaction.
With over a decade of specialized experience and a reputation built on trust, compassion, and results, Rantis has become a cornerstone for families seeking clarity and confidence in their next chapter. His ability to connect clients with vetted professionals—from estate planners to senior housing advisors—elevates the value he brings as a real estate advisor.
An 11-time Five Star Real Estate Agent and 6-time Chicago Agent Magazine Who's Who honoree, Rantis credits his success to continuous growth, a collaborative mindset, and surrounding himself with great people. “Teamwork makes the dream work,” he says. “I focus on my strengths so I can help others achieve their goals—whether that’s a smooth transition, maximizing wealth, or finding peace of mind.”
With 98% of his business coming from referrals, Rantis’s track record is built on meaningful relationships. He holds himself and his team to the highest standards—rooted in honesty, service, and the values passed down from his parents. As a proud father of three boys, he’s working to pass those same principles on to the next generation.

REVIEWS
Dace Kezbers
Mark and his staff handled everything professionally and in a timely manner. They returned calls and messages speedily saving me time and aggravation.
Daniel Worst
My wife and I just completed a home purchase and we could not be more pleased with the Rantis team. Mark, Michelle, and Angelica went above and beyond to help us move to IL from out of state. Multiple house showings, tons of questions, lots of driving around the northwest suburbs of Chicago, and excellent support leading up to the close, the team was just fantastic. This was the second time we’ve used the Rantis Group for a home transaction, and if we have any other real estate needs in the future, I know we’ll be calling Mark and the team again.

Mark and his team did a fantastic job in helping me sell an Illinois property that was the subject of a guardianship proceeding. I am located in California, and it was incredibly important to have a realtor whom I could trust, as I managed the situation long-distance. Mark absolutely fit the bill!
