  • Mario listed and sold my home

      Second to none! We had been working with other realtors and were very frustrated- then we found MG Group. We dreamed of a Bungalow to call home and with the group behind us we found our dream home! MG Group are simply the best bunch of real estate professionals in Chicagoland - I find myself referring them often to friends and clients. It was like playing on a winning team!

    • Mario listed and sold my home

        Very happy with their services, highly recommended!

      • Mario listed and sold my home

          Very informative kept me in the loop at all times.

        • Mario listed and sold my home

            Kim Smith and her team (and all of the MG Group) were wonderful! We sold our home remotely and needed more help than the average seller. They made our lives so much easier! We needed to complete some repairs on our place prior to listing. Everyone in the MG Group chipped in with ideas on improvements (painting, carpeting, repair work, etc.) and they made a series of introductions with contractors. They also facilitated the entry/exit of those individuals. Overall, the place was transformed (family didn't even recognize it!) From a sales perspective, we thought our unit was appropriately priced. Our unit was under contract within a month and the sales process was very easy on us (given the guidance from Kim and her team). The customer service level was off the charts in every aspect you could want (e.g. immediate responses, willingness to go the extra yard to get something done, and real estate knowledge). I would fully recommend to anyone who needed a broker.

          • Mario listed and sold my home

              This was the second time we enlisted the services of the MG Group to sell our house, and again they did not disappoint. Selling a home can be a time consuming, arduous task fraught with unknowns. The MG group eliminates all of that with expert knowledge of the market, expert knowledge on how to attract the right buyers, and a white glove service that can handle anything that comes up. From the moment Mario sat down with us to discuss the suggested listing price and what we could do to make the property more attractive, it was clear that he knew exactly what to do. As the process unfolded, we were able to see the efficiency of their team approach. Throughout the whole process we felt like we had an entire team of real estate professionals working on selling our house because we, in fact, did. We were kept informed throughout the whole process with real time communication regarding showings, repairs, staging, cleaning services--even checks of the property after heavy rains. In short, it's hard to sell a house, but the MG Group makes it easy. If you've come across the MG group in your search for an agent to sell your house, you can rest assured that you've found the right team, and your search is over.

            • Mario listed and sold my home

                For the last 13 years we have looked to you for guidance in our realty needs and have never been disappointed. Norma and I can’t thank you all so much for not only your professionalism, but also for the genuine care we felt you all provided during this difficult and trying sale and closing. We couldn’t be more pleased with how we were treated. I felt Fred went out of his way to make things easy for us. All the staff has been extremely pleasant and proficient.

              • Mario listed and sold my home

                  Mario and the MG Group are top-notch real estate professionals who in my opinion are the best in Chicago! Mario is extremely knowledgeable about the real estate market and how to effectively sell a property. His team is very responsive, thorough, and supportive --always willing to help. I have sold 3 properties with Mario and each one was completed with insight, acumen, and caring. I could only give them the highest recommendation possible.

                • Mario listed and sold my home

                    A daunting task made easy! Mario, we can’t thank you enough for your efforts in selling our condominium. You and the entire MG team made sure that every step in the process was seamless. Although we never met in person, your accessibility was stellar and we so appreciate all that your team did to make a long distance sale successful. Many thanks! Sharon and Rebecca

                  • Mario listed and sold my home

                      The MG group has been a fantastic sales partner for my home-building company. The team is the most responsive I’ve ever worked with. Their established policies and procedures make listing and selling homes a hands-free experience. I am grateful for their in-depth knowledge of the real estate market and I would recommend them to any builder or home seller as a trusted advisor and superlative sales team for their next real estate transaction.

                    • Mario listed and sold my home

                        Selling a house in Chicago during COVID was challenging enough. Doing it from California just added to the complexity. I wanted an agent who was experienced and knowledgeable about the business and the market. I respected Mario's candor, service, and professionalism. His team was phenomenal and kept me updated on any progress with the property - almost to the minute. Moreover, his relationships helped to expedite any service that was needed around the house. There was no task too small: when a light bulb in the stairway went out, his team got a replacement. After heavy rainfall, Mario's team checked up on the house without being prompted. I appreciated their attention to detail as it offered me some peace of mind being so far away. We worked with a contractor recommended by Mario to ready the house for sale. We ran into a problem which was expediently managed. These things happen in real estate (and in life)! We dealt with it and moved on. Although he and his group are very busy I felt the communication was superb. Mario is patient and direct. He uses approachable and inclusive language. I interviewed 5-10 agents before choosing Mario. I was a first-time seller and looked for the following things during these interviews: 1) Real estate experience (buying and selling) in the neighborhood and in my exact community/unit. 2) Personality and communication style (both during the interview as well as follow-up correspondences). 3) Sale timeline, strategy, and market analysis. 4) Presentation - in person, website, and social media (youtube interviews, Instagram, etc.) In my opinion, the key is finding an agent/team that is the BEST FIT for you and your goals. I am very happy with Mario and the MG Group and have already recommended them to family and friends.

                      • I can honestly say that Mario and The MG Group were absolutely fantastic to work with. While we have bought/sold homes a couple of times before, it is generally a very stressful experience. Prepping the home for sale, ensuring that all items are in working order, keeping the place exceptionally clean, etc. Your team was always on the ball with timely responses, keeping us informed on all upcoming viewings and how they went, and prepping us through the actual sales process. We could not be happier with your Group and the outcome. Keep up the great work!

                      • Thank you for the outstanding job in getting my unit sold. A special call out to the showing summaries you provided after every showing! I look forward to working with Mario and The MG Group again.

                        - Sam & Gayathri
                      • Unquestionably the best real estate agent in the city. Mario Greco and his entire Group make every process seamless and enjoyable. Their follow up is second to no one. Whether a builder, buyer or seller this is the place and these are the people to guide you. Specifically, John Dasdelen has unbridled enthusiasm and passion for each project/property. I found myself in the best hands with John, Mario and the entire MG Group.

                        - Jordan
                      • Thank you, Mario and The MG group. You guys were great! We appreciate all the communication and the facilitation of our sale. Cheers to a job well done! Now that we are no longer landlords, we NEVER have to worry about a clogged toilet at 2 AM on a Saturday. PRICELESS!!!!!!!!!

                      • Everything was great with Mario and The MG Group, from the quick sale through the closing. The recommendations for the roof and attorney were excellent as well. We will recommend The MG Group whenever possible. Thanks again.

                      • Mario Thanks for all the hard work your Group delivered on this transaction. If I could summarize in a few words the performance of The MG Group it would be professional, knowledgeable, effective and friendly. It gave us peace of mind to know that you would handle all questions from showings, and all the inspection and closing matters. I particularly liked the reports after each showing to gauge the prospect of each potential buyer. Im glad we chose The MG Group to sell our house, and I will certainly refer your Group to other people.

We would highly recommend The MG Group to anyone looking for the best service in real estate.
