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 (May 2026).
Inventory in Williamson County has been edging higher, with about 369 active listings in May and a modest year-over-year uptick. New listings fell nearly 10 percent from last year even as pending sales climbed more than 13 percent, showing that buyers are still writing contracts. Homes sold were down slightly from a year ago, suggesting some buyers may be taking longer to commit or facing fewer options that fit their needs.
Home values have been moving up faster than listing prices. The typical home value reached roughly $216,600 in May, more than 20 percent higher than a year earlier, while the median list price rose just over 4 percent. That gap points to buyers ultimately paying more than list trends might suggest, even though only about 21 percent of recent sales closed above asking. The average sale-to-list ratio hovered just under 98 percent, so most sellers are still achieving close to their original price.
Timing and pace have shifted notably, with median days on market jumping to 64, far above last year, even as months of supply sits around 4.2 and above the 2.9 months seen statewide in Illinois. Williamson County is still categorized as a seller’s market, but rising inventory and longer marketing times give buyers a bit more room to evaluate homes and negotiate. Whether you are a buyer trying to understand these changing conditions or a seller looking to price effectively, Agent Pronto can connect you with a local agent who knows how to navigate this market for you.

“Mike was very responsive from start to finish. Our home sale played out exactly how Mike told us it would. We had multiple offers over asking the first weekend. We were moving out of state and a smooth and quick sale is what we were hoping for and Mike made that happen. We would highly recommend Mike to anyone looking to sell their property in the Southwest Suburbs.”
“Kim has sold two properties for me this year, and in both transactions she did a fantastic job. She was always responsive, communicated clearly throughout the process, and took the time to answer every question I had. Her professionalism, market knowledge, and attention to detail made each sale go smoothly. I would highly recommend Kim and her team to anyone looking to buy or sell a home in the area. Based on my experiences, I personally would not hire any other agent to sell a house.”
“Barb was 1/20 realtors who was willing to work with me in the beginning over 9 years ago. This is when I first purchased my home. I was cheap buyer. It went without saying I was going to be using her for the sale of the home 9 years later. She handled the hurdles flawlessly and talked me through and coached me the entire way. To say I appreciate her is an understatement. I sold my home after we relocated it of state and she coordinated every logistic of that sale on my behalf to he best of her ability. I recommend her without fail and would point every person in her direction that has a need for a solid realtor.”
“Kathy fought a lot of uphill battles for us and despite hurdles at every turn (with prospective buyer) she pushed on and was able to secure our sale. I can't thank her enough for the amount of work she put in.”
“It was a joy to work with Kathryn she was able to answer every question I had, her knowledge goes a long way and I will definitely recommend her to friends and family.”
“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.”
“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.”
“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!”
