This was our second home to purchase but our first to purchase in Madison County. Carolyn was so kind and honest when it came to us looking for the perfect area to live in. It was such a long process but Carolyn was always eager and ready to drive all over the county looking for the perfect home. We appreciate everything she did for us from beginning to end and now we have the perfect house to make a home!

Carolyn's hard work, attention to detail, and good advice made the fast sale of our house possible. I would recommend Carolyn to anyone needing a great realtor.

Carolyn was great to work with. Her knowledge of local tradesmen was a tremendous help in getting accurate estimates we needed in our negotiations and she was critical in helping us to make a winning bid on our new house. We will soon be placing our old house on the market and we will be asking Carolyn to be our realtor again.

- Michael C

It has been an extreme pleasure having Carolyn on our side helping us navigate through the process of purchasing a home, especially in such a demanding market at the time. Carolyn's knowledge and experience of the home purchasing process is second to none and she was by our side from beginning to end! We were relocating from several states away making much of this process virtual and extremely time sensitive when it came to touring homes and getting paperwork delivered on time. Carolyn took on the challenge and exceeded our expectations by helping tremendously by tracking down people, mail and anything else that could of likely cause potential delays. Carolyn was more than professional at all times but also took and extra position on being a friend we could rely on; helping us learn about schools and doctors in the area for our children, showing us all of the abundant culinary favorites, and the many different fun activities and places to explore. It has been so easy and comforting working with Carolyn knowing we have the best and we would highly recommend her to anyone looking for a professional and personable real-estate agent!

We are pleased to inform and recommend anyone deciding to sell their home to quickly contact Carolyn Koester, of Berkshire Hathaway, in Edwardsville, IL. We cannot say enough about Carolyn's professionalism and real estate knowledge, and were impressed by her admiration of the company for which she works, Berkshire Hathaway HomeServices. But even more is her courteous mannerisms, care and respect for your home and your family needs. She listens and responds immediately with sound advice. She is exceptional in taking photos and overseeing the presentation of your home online to potential buyers. We sold our home in only 8 hours after posting online, with a full price offer. And, we closed in 30 days with no issues. Her presentation of our home was exceptional, and her hands-on contact with us was perfect. With deepest regards, and appreciation, Edward and Peggy Barrett
