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.

“For a first time homebuyer it feel important to have someone in your corner who knows the area and the business. Victoria and team are those people you want. She was patient, understanding, and transparent during the process. If I ever sell or buy a new home, I'll be contacting her again.”

“Kathi did an outstanding job in assisting us with the sale of our family home. Her attention to every aspect of the process put us at great ease. I would highly recommend her to anyone looking to sell or buy a property. She's your go to gal!”
Village Realty
“We weren’t sure how to compare the offers on our house beyond the price. Ryan walked us through the financing, contingencies, and closing dates so we understood the differences. He was patient with our questions and kept us updated as we moved toward closing. We appreciated being able to reach him when something came up.”
Ryan Saoudi Realtor / Schaumburg / Chicagoland / Exp Realty
“I had a great experience working with Yazen! He was professional, helpful, and responsive throughout the entire process. He made everything easy to understand, answered all my questions, and made sure everything went smoothly. I truly appreciated his patience, honesty, and dedication. I would definitely recommend Yazen to anyone looking for a reliable real estate professional. Thank you for helping us find a home !”

“We had an amazing experience working with Rizwan to purchase our first home. From our very first meeting at a coffee shop—where he took the time to understand our priorities and clearly explain the entire process—he was the perfect guide for us. We found Rizwan to be highly competent, reliable, and a deeply skilled negotiator. Most importantly (and indeed this is quite rare in our world), we always felt he had our best interests at heart and never rushed us into a decision. When the perfect house came along, he acted quickly to secure it with the right offer. We highly recommend him! P.S. He's also very fun to work with!”

“She was great to work with. Professional, personable, responsive, and reliable. I highly recommend working with her.”

“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.”

“Holly was everything and more I could ask for when I needed someone to help me with the sale of my home. After moving across country, holly orchestrated everything; from pictures to showings, to letting junk removal in, to double checking things for me. She was always a phone call away and incredibly responsive to any inquiries I had (there were a lot). Being states away now from my property, Holly made me feel at ease. And with settling into a new place and a new job, suddenly the sale of my house was on the back of my mind because I knew Holly could take care of everything. Listed with gorgeous pictures right away, four offers in less than a week and a half, and a final offer that was above asking, she did everything I needed and more. Couldn’t recommend a better realtor for your needs.”

“I worked with Eric for the better course of a year to land my first property, and Eric demonstrated extreme patience, flexibility, excellent communication, and great professionalism throughout the whole process. Eric is extremely knowledgeable in his expertise and makes the buyer feel comfortable and confident in their decisions. Eric is extremely approachable and supportive, and I would recommend anyone in the buying market to reach out to Eric with any questions, tours, or any housing-related items.”

“Ed and his team were true professionals. He made home buying very easy. His knowledge of the area and house construction took some fear out of the homebuying process. We will use and recommend Ed and his team to anyone looking to buy or sell a house. Thank you for making our homebuying less stressful Ed and Jenn.”

“In today’s world, when reviewing a product and/or business, Artificial Intelligence tends to be used to get it done in a fast and efficient manner. That would be an absolute disservice to Miriam’s work product and personality. She is genuine. She is responsive. She is intelligent. She is kind. My favorite aspect of Miriam’s work is her past experience working at a property management company. She understands how a building is run, the importance of the building’s budget, and other minor details you would never even think of. She is simply the best, and you should definitely give her the opportunity to help you find your new home!”

“I highly recommend working with Cesar. One of the things I liked best about working with him was that he really seemed to have my best interests at heart. This man will be pulling out his phone light checking basement corners for any signs of mold or water and checking above every stove to see if there’s a proper vent or not. He noticed many things on walk throughs that my parents and I may have just breezed right past and he makes sure to point out the things he notices, good or bad. They say never trust a sales person but idk, I think Cesar’s just in it for the love of the game at this point. I dragged this man to a LOT of houses and he never once rushed me. He was very insistent that we need to find the right fit for me and that I not go past the amount of money I was comfortable with. This was my first time buying a home so I had about 80,000 questions and he was always happy to talk through any questions or concerns. He’s a fun guy to work with as well. In these trying times you need a sense of humor or the home buying process will be miserable. All in all I would definitely recommend working with him.”

“My realtor nick and his team were phenomenal. It was my first time buying a home and they answered all my questions and helped me every step of the way. Made the whole process very easy. You definitely want them in your corner when purchasing a home.”

“We couldn’t have asked for a better agent than Christin Kaufman to help us sell our home. Our transaction turned out to be far more challenging than we ever expected. We were dealing with an extremely demanding buyer and what seemed like an endless stream of questions, concerns, and new requests. Through all of it, Christin was fantastic. She stayed calm, kept us focused on the end goal, helped us separate the important issues from the noise, and guided us through every new twist without letting the process get off track. She was always responsive, patient, and willing to talk through our options. Anyone can look like a great real estate agent when a transaction goes perfectly. You really learn the value of your agent when things get difficult. Christin proved her value to us over and over again and ultimately helped us get across the finish line. We are incredibly grateful for everything she did for us and would recommend Christin without hesitation to anyone looking to buy or sell a home.”

“With Diana’s marketing expertise and beautiful professional photos of our house, our house got $100k overasking within the first 24hrs of our listing going live. She did an amazing job protecting our interest and shielding us from random inquiries. We had more than 14 showings in 48 hrs, multiple offers, and several bids.”

“I have worked with Barb for years and she was so patient and understanding to my situation and was amazing with communication.”

“Renee is an incredibly knowledgeable agent that has a lot of experience, cares about her clients, and is trustworthy !! She knows the ins and outs of current real estate markets and how to strategically price a property so that it will sell in a timely manner but with the highest yield!! She has sold two of our properties over the last eight years (one in Illinois and one in Wisconsin) and we received more than we expected on each of the sales!! We cannot recommend her highly enough! Thank you so much, Renee!!”
Keller Williams North Shore West
“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.”

“Katie is very knowledgeable, thorough and kind. She worked very diligently with me to find an apartment/condo to rent! She was able to give me recommendations that I would not have found or considered on my own. I could not have asked for a better agent to work with! I have lived in a house for 30 years and really had no idea what to look for when choosing and apartment or condo. She helped me find the perfect new home, a lovely condo for rent!! Katie stayed on top of everything from setting up appointments to following through with my new landlady. She is intelligent, hardworking sweet and thoughtful. I highly recommend her to anyone renting or buying!!”
