Information and statistics on the latest trends in the Williamson County real estate market. *
April 2026
Monthly data for the latest available year.
Monthly supply and activity totals for the latest available year.
Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Apr 2026).
Inventory in Williamson County has ticked up recently, with 328 active listings in April and an 11 percent rise from March. Even with more homes on the market, closed sales climbed to 59, a strong month-over-month gain. Pending sales reached 95, only slightly below March, indicating that buyer interest is still moving properties into contract.
Pricing is adjusting to this activity. The typical home value is about $205,000, up nearly 6 percent from a year ago, while the median list price is roughly $218,000 and nearly 15 percent higher than last April. Sellers are often achieving close to what they ask, with the average sale-to-list ratio just over 98 percent and about one-third of homes selling above list, a notable jump from March.
Time on market highlights how conditions have shifted from last year. Homes now sit a median of 51 days before selling, down sharply compared with a year ago even as months of supply has climbed to 4.4, higher than the statewide Illinois level of around 3 months. That mix of faster individual sales and more overall supply supports Williamson County’s current seller’s market reading, yet offers buyers a bit more choice than before. Whether you are a buyer trying to navigate these changing dynamics or a seller aiming to price strategically, Agent Pronto can connect you with a local agent who understands this market.

“Kim did a fantastic job of explaining the current market conditions Pro's and con's and went out at and marketed to the right kind of clients and got us closed in short manner of time. She was always accessible and communicated regularly”
“Brittany is an AMAZING realtor and I don't say that lightly. She goes above and beyond to make sure that we are getting everything that we asked for and more. If you are looking for a realtor that goes out of her way to make sure her clients needs are met, you have found your realtor! I could not put into words how happy I am!”
“Lisa was amazing to work with, she was very professional, had great communication, and knowledge of everything we had questions about, was was very personable. She made the house buying process way easier and way less scary than people make it seem.”
“It was a pleasure to work with Robert, he paid a lot of attention to our expectations and preferences, and he is strong in negotiating.”
“Mike Mccatty and his son Andrew provided us with the best outcome we could have hoped for. The marketing mailers and Zillow listings were the best we saw in Orland Park at the time we were selling. Because Mike and Andrew properly priced our home we recived the offer we eventually accepted in 2 days. Selling your home is a very stressful situation and Mike and Andrew were able to reduce that stress with their quick responses to our inquiries. I would 100% recommend anyone to use Mike to sell their home.”
“Steve was always available, knowledgeable, and willing to listen to our thoughts and concerns about selling our home. More importantly, the selling of our home in tandem of purchasing a new home at the same time, went really well. If we needed to move again (heaven forbid) I wouldn't hesitate to have Steve again.”
“Working with Emir is always a pleasure. He was very helpful in coordinating work on our house for sale, working with vendors and providing valuable feedback on neccesary work vs. potential work items unlikely to generate return. We closed sale of house 3 weeks from time of first listing. I'd worked with Emir before and hope to do so again in the future.”
“Wonderful all around experience—made the entire process a breeze. Kathy and Joe are a pleasure to work with and great people. Would recommend to anybody 10/10”
“Kathryn was a calming presense and knowledgeable in all aspects of the process. I would highly recommend her”
“Working with Ray was an absolute blessing throughout my home buying journey. He went above and beyond every step of the way, always remaining patient, professional, and supportive through all of the ups and downs that came along the process. No matter the challenge, Ray stayed committed and made sure I felt informed and encouraged the entire time. His dedication, communication, and genuine care truly made a difference, and I would highly recommend him to anyone looking for a reliable and hardworking realtor.”
“Heather was very helpful from beginning to end even with the struggles and challenges we gave her.”
“Becki from Laura Topp’s team was incredible in helping me purchase my first property, a brick 2-flat in Chicago’s highly competitive north and west side market. Inventory was extremely limited and we toured at least 20 properties throughout the process. Becki was consistently accommodating with her time, prepared detailed reports for every showing and approached each opportunity with a thoughtful strategy. She genuinely treated the search as if she were buying the property for herself. When we finally found the right building, Becki skillfully negotiated with the listing agent and played a major role in getting the deal done while still protecting my interests and keeping the transaction together. The listing agent even praised her professionalism and credited her with helping secure the deal. Throughout closing, she remained diligent, communicative and focused on making sure I understood every step of the process and felt protected as a buyer. I cannot recommend Becki and Laura Topp”
“Melissa Young was incredibly attentive and knowledgeable which was critical for me as a first-time home buyer. She helped me win my very first bid with a strong offer and guided me through challenges with the appraisal process. She sets the bar high and I am so happy with my beautiful first home in Chicago!”
“To be honest Ralph was the best part of my team. He's a good person and if it wasn't for him I wouldn't know half of what I know about buying a house Thanks Ralph”
“Thanks for your help in purchasing our first home!”
“Great experience! Very attentive, honest, and dedicated. Professional, efficient, and easy to work with. Highly recommended!”
“We relocated from an area where we had lived our entire lives, and the prospect of moving to another state can often be quite challenging. However, our experience with Kimberly was exceptionally smooth and seamless. Her expertise, combined with the thoughtful and tailored feedback she provided based on our specific criteria, proved invaluable throughout the entire process. She conducted herself with the utmost professionalism while also making us feel genuinely supported, as though we were family. We would highly recommend her to any prospective buyers or sellers seeking a dedicated and knowledgeable real estate professional.”
“Our house could be considered high end property in the neighborhood. Cinny worked hard to get it under the contract in a week and sold our house a little over a month. We are happy about the result. During the process, there were ups and downs which made us nervious. Cinny listened to our concerns and gave us professional advice.”
“Dayana is the realtor for the buyer looking to purchase in a seller's market. Her expertise was the key to our acquiring the property we now own. From showing us various properties, to continually checking in with us, to putting together a competitive and timely offer, to connecting us with a good attorney, to negotiating the terms of the contract, and otherwise guiding us through the process, Dayana was the best. Thank you Dayana!”
“Shawn is a perfect example of everything a new homeowner could want in a realtor. He's patient, informative and passionate about helping you find the right home.
