Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Sep 2026).
Inventory in Williamson County has been edging up, with active listings rising about 6 percent over the past year to 393 homes. Even with more options on the market, contract activity has slowed, as homes sold are down roughly 13 percent year over year and pending sales have dipped as well. New listings have also pulled back compared with last year, so both supply and demand are adjusting at the same time.
Pricing has pushed higher despite that cooler contract flow. The typical home value is up about 17 percent year over year, while the median list price has climbed nearly 19 percent over the same period, putting local prices below the statewide median but rising faster than Illinois overall. At the same time, homes are taking longer to sell, with median days on market now around 68 days and months of supply growing to 4.8, more than a full point higher than the state’s 2.9 months.
Evidence of a more balanced market also shows up in negotiation trends. Only about 15 percent of recent sales closed above the list price and the average sale-to-list ratio sits just under 98 percent, so sellers often need to price carefully while buyers have a bit more room to negotiate. In this neutral environment, both buyers and sellers can benefit from Agent Pronto’s help connecting with an experienced local agent who understands these shifts.

“Lisa and Donna have both been wonderful to work with. I bought my 1st home with them and returned to them to recently sell my home. They made both the buying and sell process seamless and easy. They were always readily available to answer questions and went above and beyond to find me a perfect home at the time and to find the perfect buyer when we were ready for a change.”

“Our real estate agent, Nicole Canny, from Mike McCatty office is fantastic and I highly recommend her to everyone. She has been looking for the perfect house for my daughter and husband and their family for about 2 years now as they had certain requirements for a new house and a certain area they wanted to live in also. Nicole was persistent and she finally found the perfect home for them and the purchase all went quickly, smoothly and was a great experience overall. Thanks to Nicole Canny and now she will be able to sell their old house also.”

“We had such a great experience working with Victoria and Sam! They were always quick to respond whenever we sent a home we were interested in or had questions. They were willing to go on as many tours as it took to help us find the right fit and were honest about steering us away from homes with structural concerns. It was clear they genuinely had our best interests at heart and wanted us to find a home we’d love. They’re also both funny and easy to get along with, which made the entire process that much more enjoyable. We couldn’t recommend them enough!”

“Selling our first home was emotional, and we couldn’t have asked for a better realtor than Brittany. When our first offer fell through, she had us under contract with a second offer within 24 hours! Her unwavering confidence and steady reassurance helped us feel at ease during such an uncertain time, especially as first-time sellers. Brittany supported us every step of the way, always making time to listen, answer our questions, and talk through our concerns. We felt heard, cared for, and confident that she had our best interests at heart. This was our second real estate transaction with Brittany, and we would never work with anyone else. We’re so grateful for her dedication, expertise, and kindness. We cannot recommend her highly enough!”

“Working with Anthony was an absolute game-changer for us as first-time home buyers. He knows the local market inside and out, he answered all of our (many) questions at any time of the day, and not only was he very professional and reliable, but we knew throughout the process that he genuinely cared about us and our satisfaction. Now we have our dream home! I'm so glad we had Anthony working with us throughout this process, and we highly recommend him!”

“I can’t say enough wonderful things about Steve Goodman and the experience we’ve had working with him over the past 10 years. Steve was my realtor when I purchased my very first condo, and 10 years later, he was right there with us as we sold that condo and purchased what we hope will be our forever home. Having the opportunity to work with the same realtor through such an important chapter of our lives speaks volumes about the trust and confidence we have in him. What sets Steve apart is that he genuinely puts his clients’ best interests first. He is never pushy or focused on simply making a sale. Instead, he takes the time to listen, answer every question, offer honest advice, and make sure you feel comfortable with every decision. He is incredibly patient, knowledgeable, and always willing to go the extra mile.”

“We were referred to Tracy in our move from downtown to the suburbs, and we couldn’t have asked for a better experience. She made what can be a stressful process feel easy and manageable from start to finish. Tracy was both professional and personal, detail-oriented, responsive, and always quick to act when it mattered. Her deep knowledge of the local market and strong connections were invaluable throughout our purchase. We would wholeheartedly recommend Tracy to anyone looking to buy a home!”

“Michelle was exceptional throughout the entire home-buying process! She was always on top of the paperwork, deadlines, and everything we needed to get our purchase completed. Her responsiveness, organization, and attention to detail made the process so much smoother. We truly appreciated all her hard work and would highly recommend her to anyone looking to buy a home!”

“Catherine Terpstra made herself available to us in our search for a house as we were moving from out of state back to IL. As soon as we contacted her, it felt like she dropped everything "just for us". (We know she was attending to other clinets, as well!) She was very efficient in setting up houses for us to tour, within and without our pricing perameters. She "heard us" in regard to the "non-negotiables" we had for a house for which we were looking. She printed out pertinent infomration on each place for us. We were in a time-crunch, as we had come from out of state to search for a place to live. She was able to help us find a very nice new home. We are very thankful to her for her understanding and expertise in real estate and in the current housing market.”
