“"Working with Kim Wirtz was such a great experience! She made the whole process easy and really took the time to listen to what we needed. Kim was always available to annswer questions and guided us every step of the way . I couldn't have asked for a better realtor"”
“John was a great Realtor many years of experience definitely knows his market. John is definitely one of the people that will get to know his sellers his clients and every time that I had any issues John always answered within an hour sometimes within minutes the funny thing is is that one day out of the blue John contacted me Wanting to know if I wanted to sell my house and I said you know I've been thinking about it cause I had a tenant in there and I have some severe medical problems and John waited and waited and waited through all the endless phone calls and follow ups. He ended up getting my business because he was patient. He waited and it took over a year of us working together to get my house on the market and it's sold in two weeks. I cannot say enough good things about John, but I do thank him for his patience and his understanding with my personal issue and I promised if he didn't give up on me, he would get the business and he got it!”
“Brittany was the best agent anyone can ask for always very informative and guided me threw all the steps as a first time home buyer I can not say enough about how amazing/professional she was as a first time home buyer i would recommend her to anyone who really wants someone to be in your corner on getting the perfect house that best suits your interest i found a home perfect for my family and it was all thanks to Brittany absolutely amazing 10/10”
“Vicky was great to work with. She was easily accessible, knowledgeable and smart. She priced the house correctly and got us a full price offer twice. I would strongly recommend Vicky for you future realtor needs.”
“Nancy Silwa is an experienced realtor who knows her profession. She knows, and in fact lives in the area, where I was selling my house. This was a bonus as she really had a handle on the market. She walked with me every step of the way so that I understood the process. I was selling a home I had lived in for 43 years. Nancy understood the emotional impact of this decision and gently helped me stay focused on the task at hand: sell the house. She found the perfect buyers. A young couple who will make my house their home. Knowing this made selling my home a little easier. I would and indeed have recommended Nancy to others. She is simply THE BEST!”
“Exceptional professional and person. Meldina was so kind and supportive through the entire process of buying my first commercial purchase.”
“Laura Topp was recommended by a trusted friend, a friend whom I will trust even more after this experience. Laura is extremely knowledgeable, personable and very well connected in the real estate market. Laura and her team (including Becki, also very involved in my sale and purchase) went over and above to insure my then-current home was sold in a timely manner (it was a matter of days, in fact) and for the best possible price! As for my purchase, Laura connected me with not only public but also private listings, and I also found/ contracted for my new dream home within days. In addition to her knowledge, expertise and connections, Laura is also one of the kindest people have ever met; she made me feel valued and supported throughout this entire process. I would recommend Laura and her team in a heartbeat (I already have) and although I was not previously aware of BHHS, this company also has high ratings in my book because of Laura and Becki.”
“Heather was a dream to work with in our home buying journey. She was very responsive, patient, and understanding of all of our needs when it came to what we wanted in a home. Her great personality and good sense of humor made her a pleasure to be around. Her knowledge and recommendations made our process smooth and painless. My wife and I highly recommend considering Heather all of your real estate needs.”
“My Wife and I were first time homebuyers in a very difficult market. Renee guided us through the process and answered any and all questions we had. We're extremely pleased with the end result and would happily work with her again in the future.”
“We live in Florida and were wanting a second home in the Plainfield, Illinois area. We were not seeing too many places that were available. She showed us a few places in January online but they didn't work out for us. Since she knew what we were looking for, a condo went on the market that she thought we would be interested in. We happened to be in the Chicago area in March so we investigated the condo and sure enough we liked it and made an offer, and subsequently purchased. We were lucky that she remembered what we were looking for, and are so grateful to her for that, We also appreciated that she was not high pressure and that would have been an immediate turnoff for us. She was very helpful throughout the whole process and we would recommend her highly. Thanks again Kathy!”
“Steve is amazing! This sale was not easy, the contracted buyers were difficult but Steve negotiated for us, put us first, advocated for us, and he always presented all information. He is an agent who cares deeply about his clients and he is always working for the client not his wallet. I would refer and recommend Steve to anyone! He's absolutely amazing!”
“I had an amazing experience working with Erick when purchasing my new home. From the very beginning, he took the time to understand exactly what I was looking for and offered valuable insights into the housing market. Erick was incredibly knowledgeable, patient, and responsive, answering all my questions and guiding me through every step of the process. The process of finding the perfect home can be overwhelming, but Erick made it seamless. He was always available to schedule viewings at my convenience, and when we found the right place, he worked tirelessly to ensure my offer was competitive and that all the paperwork was handled efficiently. Thanks to Erick, I now own a home that I absolutely love. I highly recommend him to anyone looking for a dedicated and professional real estate agent.”
“Very hard worker and knowledgeable in realestate”
“The referral of Mike Frank was the best decision we made! Mike Frank is detailed, thorough, responsive and a joy to work with. He went above and beyond to deliver us the kind of customer service we could only have hoped and imagined. Results and not excuses! Thank you for this referral!”
“Tina Grzeca did a phenomenal job helping us remotely house hunt. She organized both virtual showings and quickly got physical showings scheduled when we were able to be in town. She was also exceptionally detail oriented, pointing out important considerations in the houses we toured and making sure they would meet our needs. We would highly recommend Tina Grzeca for both local and remote people looking for their next housing journey.”
“very professionel very nice helpfull available juste perfect”
“We had to sell a relative's house after her death and we live over an hour away from the property. We used Agent Pronto to interview three different agents because we were unfamiliar with the area. We settled on Scott Paul. He is by far the best realtor we have ever worked with. (We have worked with six other realtors over the years.). He is professional, conscientious, thorough, and hard-working. We highly recommend him.”
“I highly recommend William for Buying or Selling a home. He has helped many members of our family and is trusted like a friend.”
“Agent Pronto helped up find a good agent in Larry. He was a pleasure to work with and helped us through a challenging sale.”
“Anthony understood us, our personalities and interests. We were able to relate to him in a number of ways and that made us comfortable working with him. He was a compassionate person, and it meant a lot to him to find places that served us, which also meant a lot to us. We gave him some of our requirements for a home, and he would continue to refine his search accordingly. He did not discriminate homes based on their pricing. When we wanted to check out a much more inexpensive house, he worked hard to get us a showing. It seemed like he cared more about finding us a place we would be happy than the amount of his commission. He was willing to do a lot of traveling, and even worked late hours for us. I would never ask someone to work late or early, but he took it upon himself to do so several times, which we highly appreciate. Anthony found us a great inspector, and did a lot of mediation for us that we so desperately needed. He was honest when he wasn't able to help with certain things that were outside of his job description, like advising us financially. However he was able to find an attorney and a lender that we ended up really liking, who also cared about us and were available any time we needed them. Anthony feels like a friend, and we will be sure to hire him if and when we move again.”
Information and statistics on the latest trends in the Union real estate market, updated for August 2025. *
Market gauge is calculated based on the the number of active listings divided by home sales over the most recently available reporting period.
Union offers residents a close-knit, welcoming community with easy access to parks, schools, local shops, and a reassuring sense of hometown pride.
Union pairs wide-open prairie views with a tight-knit rhythm of everyday life. In McHenry County, the village sits minutes from Marengo, Woodstock, and Harvard, making errands, dining, and Metra connections straightforward while preserving a take-it-easy pace back home. Its calling card is the world-class Illinois Railway Museum—an immersive campus of working streetcars, diesel and steam locomotives, and seasonal rides that draw enthusiasts and families alike.
History runs deep here. The McHenry County Historical Society & Museum anchors Union with exhibits, archives, and community programs that illuminate farm life, industry, and the people who shaped the region. Outdoor time comes naturally, too: quiet country roads and nearby preserves invite morning walks, fall color drives, and the kind of starry nights that are hard to find closer to the city. Weekends might feature antique browsing, a leisurely breakfast, and an afternoon rail excursion, all without leaving town.
Schools are a point of pride. Younger students attend Marengo-Union Elementary Consolidated School District 165, while teens continue at Marengo Community High School, both offering a full slate of academics, arts, and athletics supported by engaged families. Housing ranges from farmhouse acreage to in-town cottages, and the market rewards buyers who value space and authenticity. Whether you’re planning a move or ready to sell, Agent Pronto can connect you with a trusted local real estate professional to make your next step seamless.
