Connie Antoniou

What do Clients Say?

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.

Scott & Molly

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

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.

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.

Stephanie

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.
