Connie and her team (Muge and Mari) were exceptional from the start. They gave us clear guidance, provided us a staging assistant to make the presentation great, and were quick to get the sale started. They also did an exceptional job with the pictures, video, and sale presentation. During buyer visits they were exceptionally knowledgeable of the home which motivated much interest. Thanks to the great efforts of Connie and her team, we sold the house in a week. Amazing!
Intimate knowledge of the North Barrington market. Good advise on getting the property ready for sale. Very good negotiation skills. Connies team marketed the property in a very effective manner which enabled us to sell the property sooner. There was no pressure ever to reduce the price of the property to sell quickly. Connie is a cut above the rest. Muge was always there to help. We are glad we went with Connie and team. Connies team also helped us buy our next property and they did a very good job there too.
Connie and Tony are class acts through and through! I could weep over how happy I am with the entire experience. Tony went above and beyond at every step of the way. Not only did he have the best communication, he was such a joy and is genuinely a wonderful human being! His work ethic, commitment, professionalism are top-notch!
Connie by far is the best in town! I have bought & sold 3 homes with Connie and she has always got me the best price possible. But its her understanding of the large market with a small town girl touch. She really connects and goes above & beyond what a realtor does. She will get her hands dirty & truly helps from the bottom of her big heart! She has your best interests on both sides. She made it very easy & smooth transition to a new home.
We had a amazing experience working with Connie and her team (MugA? and Katerina)! Connie is incredibly knowledgeable on the local market, and especially Wynstone. I can be (obnoxiously) picky, and Connie was determined to find the right fit. Having a team around her meant that someone was available to assist us at virtually any time. She ultimately got us into and helped us purchase a home before it hit the market, and we couldn't be more grateful. When it came time to sell our other home, Connie and team made the process extremely easy, ultimately selling the first weekend well over asking price. We couldn't have asked for more! We're so glad to have met Connie and will recommend her to all of our friends looking to move to the area!
I had an outstanding experience working with Connie and her team. From the very beginning, they were knowledgeable, responsive, and incredibly professional. They took the time to understand exactly what I was looking for and guided me through every step of the process with patience and expertise. Highly recommend!
I was fortunate to have the opportunity to work with Connie and her team. Connie is highly knowledgeable when it comes to the demands of the market and recognizing the story built around your home. She is able to bring buyers who appreciate the little things that will make your house a home for years to come. Connie and team are always available to answer questions, whether simple or unexpected. Her honest no nonsense approach enables the seller to relax and trust in the process.
Connie Antoniou is a creative, well-respected, honest, trustworthy, successful, excellent, professional real estate agent. She not only represents herself well, but she also represents Jameson Sothebys well in her far-reaching marketing plans and executions. She goes over and above to meet your needs, meet contractors, do multiple showingsaEUR"all with that great can-do attitude. Her years of experience and her wealth of knowledge are so valuable! Connie did an excellent job in selling our house. We have known Connie for many years, and we highly recommend her as a fabulous real estate agent whether you are buying or selling real estate!
I would like to write this review for my experience in selling my home and using Connie Antoniou as my agent. I chose Connie because she was selling homes in my neighborhood for near asking prices when other realtors were not. Connie suggested staging and provided any contractor needed to improve and update the appearance of my home. Not only did she recommend and provide said contractors, but they responded immediately to her and were often the fairest price for the work involved. After we retained Connie we had two good offers and she saw the last offer through every detail until closing. I recommend her to anyone because she is hardworking and professional and knows the real estate business inside and out. We were happy to sell our home very close to our asking price.
After lack of success with another real estate agent in the area, we asked a colleague who had recently sold his estate for a recommendation; he highly recommended Connie. Our turn to do the same. Extremely competent, knowledgable, and professional. She came up with creative solutions to overcome challenges and help us in fixing and marketing our Barrington house, as we live out of state. Our house sold very quickly. Highly recommend!
Absolutely Awesome! Selling my home with Connie was a truly outstanding experience. We were living in Florida when we decided to sell our home in Illinois. We chose Connie and her team because of their exceptional reputation. Their individualized "hands on" approach was even greater than we anticipated. They managed all the details from marketing, creating our home to show best, to the final closing. The expertise of her entire team made what could have been a challenging and worrisome task, stress free. (A special thanks to Kate for her "above and beyond" help.) Their plan was executed to perfection. Our home sold quickly. They were more than just a realtor. We felt like we were working with trusted friends. We would highly recommend Connie and her team to anyone interested in buying or selling.
Connie and her team helped our family sell our existing home and purchase a new home this summer. Our experience with Connie through this process was nothing short of exceptional. I originally contacted Connie because of her expertise in the location we were looking to purchase as well a strong recommendation from a friend. Purchasing and selling can certainly be stressful. And I think everyone's hope is that they can find an agent that is going to meet their expectations in every aspect of the task. Connie was always prompt with communication, always available to answer questions, had the highest standards of professionalism and had impeccable attention to detail. She and her team made the entire process very manageable. I actually hope that I don't have to sell or purchase another home for quite some time. However if and when that times arises, I would most certainly contact Connie and her team without hesitation. We could not be happier with the fantastic job she did with the selling of our home and the purchase of a new home. Thank you.
Connie and her team helped me through every step of the selling process, from marketing and staging my home to negotiating the sale price. They were a pleasure to work with, and were always responsive to all my questions, and concerns. Connie's professionalism, knowledge, honesty, and hard work ethic all contributed to my home going under contract during processing. Her advice was always reasonable and honest. I would highly recommend Connie to anyone looking for exceptional real estate services.
Connie and her team are outstanding on every level. We had used Connie to help us find our home (her local knowledge and advice in this regard is truly unmatched) and so, when we decided to sell, it made sense to work with Connie again. The service Connie provides is described as a concierge level sales experience, and it does not disappoint. Above and beyond. Excellent advice from valuing the home, staging, marketing and all the way through to negotiating, closing and post-sale Connie and the team assisted to the highest level. We had multiple offers at list price before our property even went live and we closed not long after. I could not recommend Connie and the team more highly.
I would highly reccomend Connie to anyone looking to buy or sell a house. I have bought and sold multiple properties and have worked with several other realtors so I have the experience to make a pretty accurate compairson. Connie is not only the hardest worker out there but she also knows how to get a deal done! I live in a very expensive gated country club community where houses can take more than a year or even two to sell, Connie sold my house in three month and she didn't do it by "low balling" the price. We got the full asking price!! I also bought my new house with Connie. Connie is the best !!
Connie Antoniou home #2! We relocated to the Chicago area September 2019 after 35 years in Kansas City. It was difficult to even know where to begin that house hunt until a former neighbor suggested we give Connie a call. That was the best thing we did because she truly understood all the expectations we wanted in our new home. She actually found the perfect home and location for us the first day we met! Fast forward one year later and we were being transferred back to Kansas City and needed to sell our awesome home quickly. We called Connie and she again worked her magic and got it on the market for us in record time. Within 30 days we had a contract on our house, which made our return to Kansas City much less stressful. Connie and her team once again went above and beyond our expectations. She was always available and made sure the entire process and our move to Kansas City went smoothly. The time she devoted to selling our home made us feel we were her #1 priority. Connie Antoniou is an amazing, professional, caring person and realtor that we highly recommend!
Connie Antoniou is hands down the best real estate broker we have worked with over the years. Connie helped us to sell our Wynstone home and to buy a new home (as well as to rent a house during the interim). In all cases, Connie and her team were professional, responsive and very knowledgeable about the market. Her attention to detail before, during and after the sale ensured that our home was in excellent shape, properly staged to sell, and excellently presented. Connie or someone from her team was always present at each home showing to ensure questions were answered and input provided. We received the same attention to detail from Connie and her team when buying a house. She is hard-working, ethical and always has the best interests of her clients at heart. We not only admire her as a topnotch business professional, but we also admire her as a person that we genuinely trust, like and enjoy working with. We would definitely work with Connie again, and highly recommend her to anyone interested in selling or buying a home! Sincerely, Craig & Cecilia

We first signed on with Connie to sell our house because of her reputation as a highly respected real estate agent in our area. We found her knowledge of the market was insightful and she was extremely helpful in guiding us through the entire process. Connie and her staff were always available to answer any questions and helped us out in any way they could to make a difficult time easier. They are extremely conscientious and we would highly recommend Connie and her staff at Jameson-Sotheby to anyone in need of their real estate expertise.
If you want the job done--Connie is the real estate agent you want. She is professional, yet very approachable. She knows the market and can be trusted. You will not be disappointed.
Working with Connie was like a dream come true. She has been so responsive and on point since our first phone call. She holds her team accountable and equally as charged to get it done. Our purchase took us less than 30 days from start to closing. We are still blown away and can't wait to begin our bigger project that Connie has agreed to support and partner with us since we have many big things to do...and Connie knows everyone! Reviews are easy when you mean every word, and if you had or have any doubts about who you're dealing know one things...Connie's THE VERY BEST!!!Sincerely,Tim & Kristin
Connie and her entire team are wonderfully professional and were most definitely in our corner when searching for our dream home and selling our current home. Their staging, photography, and videography were on target to sell our home very quickly. I highly recommend Connie and Jameson Sothebys International Realty. Simply the best!
Connie was extremely friendly and helpful with purchasing our home. This was our first home buying experience and she made it seem so easy. We had a tight window to close and Connie made it happen with rapid responses and making sure every party involved was on the same page! We will definitely be using Connie again in the future!! Highly recommend anyone buying a home to give Connie a call!
We selected Connie for our purchase on Wynstone because of her wealth of experience in the local market, but we did not anticipate just how good she really is. Weve dealt with a number of realtors in different states and countries, and Connie is by far the best we have ever worked with. Her attention to detail is phenomenal, as is her ability to truly understand your personal preferences quickly and translate that into a house selection that is just right for you. Connie is proactive and inspires confidence for you to trust her to get things right and she is there for her clients 100%. Connie helped us every step of the way, excellent advice and insight from start to finish, a delight to work with and we are very appreciative of all she did for us - we have a perfect home now and a realtor we will use for all our future purchases. We would highly recommend Connie.
Connie helped my wife and I in our re-location from Florida to Chicago. She always has her clients interests at heart, will do whatever it takes to make sure you get the home you want, and knows the marketplace unlike any other. We were so happy we had Connie as our agent. We got the house we wanted, and believe we paid the right amount for this home because of the knowledge Connie shared with us regarding the marketplace.
Connie went above and beyond for us! She was always there to answer any questions we had. Connie knows this area. She is friendly accommodating and very knowledgeable. Anyone would be very happy and lucky to have her as a realtor.
I've known Connie for years and have used her many times in the past for selling real estate. She recently helped me sell a land parcel which was listed for awhile and proving difficult to sell. Not only was she dedicated to getting this parcel sold, once we had a contract signed she became an invaluable source of communication with the buyers and their agent to see the deal through to closing. Her professionalism is unmatched as well as her patience and knowledge of the market. I will be delighted to hire Connie again for future sales and will recommend her to anyone I know looking to sell or buy a home.
Connie was a top level realtor. We chose her because she has great energy, professionalism and knowledge of the markets. She provided several great resources to help us sell our home that we actually used. Also, she had great assistants who were responsive and helpful in all manner of things. Lastly, she had several out of the box, creative ideas that really demonstrated the depth of thought she puts in to doing everything possible to help a home get sold. I would absolutely use her again and recommend her to friends and family. Bryan
Relocating to the Chicago area after 35 years in another city was a huge endeavor for us. We didnt know where to even begin our search and were getting frustrated with an assigned relocation realtor. This all changed when our next door neighbor told us his brother lived in Chicago and gave us Connie Antonious name. Fortunately after one phone conversation with Connie we knew she was going to be the perfect realtor for us.Connie spent time getting to know us and what we looking for in our new suburban Chicago home. Because of her efforts we stopped wasting time looking in areas that werent right for us and quickly narrowed our search to communities we were very comfortable with and fit our list of requirements.We had two days in Chicago to find our home and Connie nailed it!! We looked at 10 plus houses and ended up buying the first home she showed us. Her knowledge of the area and work prior to our visit made the house hunting process a very positive experience. Connie went above and beyond our expectations and we absolutely love the perfect home she guided us to. She was always available and made sure the entire purchase, closing process and our move to Chicago went smoothly. The time she devoted to us made us feel we were her #1 priority. Connie Antoniou is an amazing, professional, caring person and realtor that we highly recommend!
Connie is Savy in social media. She and her staff keep you abreast of the competition and current standing in a difficult market for the seller. The automated app for showings was helpful and timely. Connie kept her cool when challenged by strong personalities and difficult situations.
I had to pack, clean and sell my childhood home - Connie and her team were incredible in helping and supporting me every step of the way. Connie is professional, knowledgeable, personable and caring - I would highly recommend her to anyone and hope to work with her again in the future.
Great attention to detail on my needs. Great follow up, always with great options for me. Definitely recommend working with Connie and her team.Danielle was always in touch and available to go see homes when needed.
We selected Sotheby's in 2017 - Connie Antoniou and her team because we were convinced - and rightly so - that her team would be represent our home - something we treasured living in for more than 15 years. Her team worked so hard to create a great marketing program and we ended up selling to a wonderful family with two young girls who will grow up and make the next generation of memories, attend great schools and be in a neighborhood that we loved.
Connie is an outstanding realtor. From first discussing listing our home through its sale at closing, Connie was knowledgeable, strategic and extremely helpful. We were always impressed with her proactively pitching in personally to help stage, physically move items and improve the probability of a good sale. She followed through in all aspects and we always felt she had our best interests at heart and listened to and responded well to our needs.
We put our house on the market in November which is not an ideal time to sell. Connie did a wonderful job of staging and marketing the house; we were under contract within weeks at a price that we were very pleased with. Connie worked at all hours to make this deal come together and to limit our stress. She was even fabulous with helping us find the best movers and contractors to hire for the sale. We bought a new home thru Connie and that experience was equally as wonderful. Connie is honest, hard working and quick to respond. We will work with her again without question.

Connie not only sold my home in Hinsdale, but also helped me find a new home in Burr Ridge. She got me a very fair price for my home in Hinsdale in 2011 when the market was lousy and an even deal in Burr Ridge. Both transactions were handled quickly and professionally. I have recommended Connie to many friends. She knows all there is to know about residential real estate!! Use her!!! Nancy

Connie sold my home for me in Hinsdale in 2010 when the market was in the dumps. My home was on the market for 18 months before a buyer presented a bid. Connie advised me to take the offer, even though it was a little lower than I wanted. BUT, we found a great house in Burr Ridge for a low price after Connie took me out several times. Connie negotiated a great price and we stood our ground. The sellers accepted. She was professional and courteous and both transactions were handled easily----no problems!!! I have recommended her many times over!Nancy
I have known Connie Antoniou for over 20 years and she has sold two homes to me and has sold my home and that of my father-in-law. She is a true professional who is extremely knowledgeable, personable and represents what you would want to have when choosing a realtor. Connie has demonstrated her ability time and again to get results when it comes to showcasing the strengths of a home and presenting it to the most qualified buyers. She also found the perfect house for my family as soon as it came on the market and advised us expertly on how to proceed once we decided to make an offer. Not only did Connie do a great job with the purchase and closing of our homes, she has been an amazing wealth of knowledge whenever we needed help selecting vendors to assist us with interior design, repairs and maintenance. She has always been available to talk over any concerns we had even long after the purchase or sale of our home was complete. I wholeheartedly recommend her to anyone I know and have done so many times over the years. No one has ever been disappointed. With her expertise and capabilities, I will definitely call Connie when it's time to sell my current house.

We've worked with Connie on a few homes over the years, and have recommended her to numerous friends. Knowledgable, and always shoots straight. It's easy for me to see why she is consistently one of the Top Realtors in the country, year after year, for over 20 years. If you're looking for the BEST, go no further, just call Connie.

My professional experience with Connie Antoniou dates back dto 2001when she sold my home in Oak Brook in 8 days. The transaction went beautifully- as did subsequent transactions - the purchase of a townhome and the sale of a home in Ginger Creek in 2013. I have found her to be responsive, knowledgable and above all, respectful to parties on both sides of a transaction. I would not hesitate to use her again or to refer a friend.
We've had 6 homes over the years, and found Connie in time for our last move. Wish we had met her years sooner!
