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.

Very professional, highly recommend

Where to even begin with all the assistance Mark provided me when I was trying to sell a deceased family member’s house in another state?
He’s not just average realtor; instead, he’s someone who can take care of every possible issue that might arise. And I literally mean every issue: radon in the basement, water leaks, broken locks, furnishings that remain in the house, valuables that need to be sold. If he can’t take care of it himself, he’ll quickly find someone who can—and someone who will get the job done right and at the right price.
And on the realty side, Mark will work with you to get you the best price possible. He was in constant touch with me, apprising me of developments and advising me on options.
Not once did I wonder, “Gosh, I wonder if Mark will ever call me back.”
With Mark, you get a one-stop shop, which is just what you need when you’re trying to manage a sale from afar. He was a true Godsend.

Mark, and his team, are awesome! He worked so well with us and was incredibly patient with all of our questions and concerns. As it turns out, we had quite a few questions! The crazy thing is that we originally thought we would sell By Owner. But, other things in our life required more attention than we anticipated, so we decided to delegate this responsibility. We sure are glad we did! Once we were deep into the sale process, we realized that selling our house was too complicated to have done without a professional like Mark by our side. Our house sold within a few weeks and we got what we wanted for it. It was definitely less stressful than if we had done this ourselves. We will be renting for a while, but our son (who was living in our house) needed to buy a place. Mark was the buyer's agent for our son to find his condo. He is now our family realtor.
