    After nearly a year of frustration with trying to sell my property, I took it off the market to regroup. During that time, I was contacted by Haakon Knutson and The MG Group and knew immediately they were the ones. I was updated every step of the way and absolutely every single person was great to work with and so kind. Even better, I had an offer in 10 days thanks to their relentless followup with prospective buyers. This was a GREAT experience and I will recommend Haakon Knutson and The MG Group to absolutely everyone I know!

    Thank you Mario and The MG Group for all of your efforts to ensure an efficient and highly effective sale process for my condo. Your team’s professionalism is unmatched and your ability to run the sale process much like a corporate M&A transaction is a true differentiator. Thank you!

    t’s been so great as first-time buyers to have all the wisdom and knowledge that your Group has brought. We were able to really relax and enjoy the process of looking at places. Alice was fantastic about getting us in to see what we wanted, suggesting places that we might have overlooked, and helping us be as careful and critical as we needed to in this process. And the whole Group has been wonderful with making us feel like we were being guided and protected through procedures that were totally new to us!

    We recommended you to our friend based on the experience we’ve had, and we will totally continue to recommend you. :>

    I simply can’t say enough. We had a tough property we were trying to sell remotely, and Mario and his folks went so far above and beyond, it was incredible. We had the first contract fall through (no fault of the MG Group – buyer flaked out), and they dove right back in, coordinating getting it back on the market and back under contract fast. Because we sold remotely, MG Group had to do EVERYTHING, and they rocked it. Could NOT have asked for better, and while they may not want any referrals from us after what a pain in the butt our property was to sell, they’re going to get them!

    Mario and his group are outstanding. I had bought through Mario previously and just bought/sold properties to meet our growing family. He has such a deep understanding of the market and entire process. The Group was great and it was an extremely efficient process. And, Mario was extremely helpful in finding a necessary contractor to help with a small issue that arose during the sale process. He was honest, insightful and transparent with all parties. I will continue to use the MG Group.

    We’ve relied on The MG Group several times over the last ten years. They’ve helped us buy and sell a condo, navigate a short sale, find a rental home and buy a house. We really can’t imagine ever using anyone else. Everyone is extremely engaged, friendly and easy to work to work with. They know when to be aggressive and when to be patient and are the ultimate in professionalism. Thanks in particular to Haakon, who’s never too busy to answer a phone call or an email and makes us feel like we’re not just clients, but friends.

    Hi Mario, Alice and team - just wanted to send a quick note of thanks for all of your work on the purchase of our loft! We've been there for a week now and absolutely love it. We appreciate how easy the process was with all of the help and support we received from you guys. Will definitely recommend your team to anyone we know who needs to buy and/or sell in Chicago or the ‘burbs.

    One of the best decisions we ever made was to allow The MG Group to sell our condo! You have a great crew! We will definitely pass your name along and recommend your services to anyone looking to buy or sell a home. Truly the best and most professional group we have ever worked with and we have bought and sold many homes over the years. Thank you again, Mario, from both me and my wife!

    We are both business professionals and understand what it takes to win in business. It is crucial to only work with the best and The MG Group is simply the best in the real estate business in Chicagoland. This is the 3rd property that Mario helped us sell since 2005. They are very unique properties located in different areas of Chicago. Over the years, Mario has established a group that gets the job done regardless of area and price range. Real estate transactions can be stressful enough, but The MG Group really does make it stress free. We will recommend The MG Group to everyone we can.

    Mario Greco and his team did a great job giving us guidance on staging the property, the market price, bring in a good number of potential buyers, communicating to us a summary of the potential buyers feedback, keeping us informed on the next step in the process, negotiating contract terms and quickly closing at our asking market price. The team was extremely responsive to call-backs and answering any questions that we had regarding the sale of the property. My wife and I have purchased and sold a number of homes over the years and Mario and his team rank as #1 in our experience.
