Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Jul 2026 - Sep 2026).

Year over year in Lake Koshkonong, prices have edged higher while listing prices have climbed much faster. Typical home values over the latest three-month period are up about 9 percent from a year ago, while the median list price has jumped more than 40 percent. Sales activity has also expanded, with homes sold more than tripling compared with the same time last year.

Looking at the most recent rolling three-month view through September 2026, conditions show a slower pace and more selection. Active listings are up more than 40 percent from a year earlier, and months of supply sits at 8.6, signaling that buyers have many options and time to decide.

Homes are taking much longer to sell, with the median days on market stretching to 324 days in the latest period, compared with under three months a year ago. At the same time, the average sale-to-list price ratio has slipped to about 91 percent, and no recent sales closed above list price, which can give buyers more negotiating power. New listings and pending sales are both substantially higher than a year ago, showing that sellers are still bringing properties to market and buyers are still writing offers. With these shifting dynamics, both buyers and sellers in Lake Koshkonong can benefit from Agent Pronto’s help in finding an agent who understands the current trends.



Learn more about what Lake Koshkonong has to offer.

Lake Koshkonong offers residents a welcoming lakeside community with abundant outdoor recreation, boating and fishing, and a strong sense of neighborly connection.

Lake Koshkonong stands apart from nearby communities like Janesville and Fort Atkinson with its expansive lakefront identity and relaxed, year round resort atmosphere. Here, life revolves around the water, from quiet weekday fishing to lively weekends at lakeside spots such as The Anchor and Sunset Bar & Grill. Many homes are tucked along channels or within walking distance of public access, giving both full time residents and seasonal owners a strong connection to the shoreline.

The area feels small scale yet well connected. Families appreciate access to Fort Atkinson School District and Edgerton School District, while daily needs are met in nearby Edgerton and Milton. Outdoor enthusiasts take advantage of Koshkonong Wildlife Area for hiking and hunting, while the Rock River Trail offers paddling and cycling options that link Lake Koshkonong to river towns up and down the corridor.

Real estate here ranges from modest cottages and condos to updated year round lake homes. Waterfront and near lake properties can move quickly, particularly before and after the peak boating season. Whether you are planning to buy into the lake lifestyle or considering the right moment to sell, connecting early with a local agent who understands shoreline regulations, seasonality and pricing patterns on Lake Koshkonong can make preparation smoother. Agent Pronto can help both buyers and sellers find that agent and make the most of their timing.

“Chris and his team made purchasing my first house very easy. Communication was top notch. Every question i had was answered in a timely manner and broken down enough for me to understand what was going on during the whole process. I have already passed on his info to several people looking to buy. I will absolutely go through him again if I'm in the position to buy again.”

“We worked with Matt and Candie on real estate transactions in Cape Coral, FL, Ft. Myers, FL and Madison, WI. With all 4 transactions, their knowledge of the market and neighborhoods was excellent. They have great negotiation skills when it came to purchasing and selling our homes. They were also very helpful in all the aspects of selling and buying a new home. Whether you needed help finding a service provider to get something repaired, coordinating with getting utilities switched over, or getting your modem out of the home before closing, Matt & Candie were always there. They are really great partners to have when selling or buying your home!”

I was completely comfortable with Bob. If you're looking for someone who has your best interests in mind,hire Bob.”

“Dre was highly recommended to my partner and me by one of our co-workers, who is also a realtor. After meeting him for the first time, we both knew he was the right realtor for us. He presented as professional, methodical, and knowledgeable, and his demeanor really put us at ease. We were immediately comfortable around him. As we continued working with him and getting to know him, we also found Dre to be reliable, patient, and attentive. As first time homebuyers, this was exactly what we were looking for. He's exceptional at all the things you want him to be exceptional at: scheduling and coordinating showings, letting us take our time in the houses, walking us through the paperwork and the processes with remarkable patience, even when we asked the same question multiple times. Where Dre really shines, though, is in his responsiveness. He was always incredibly communicative with us about his availability, and he was more than willing to take calls or have extensive text message chats at all times of the day. It felt like we were his only clients, which we certainly were not, but that was level of attention and focus he gave us. One example stands out above the rest: There was a new house on the market we really wanted to see on the first day it opened (a Saturday), but Dre was unable to take us to a showing himself since he was out of town, something he had told us about two weeks in advance. We wanted to make sure we were the first people in there, though, and he went out of his way to make it happen by connecting us with one of his other agents who was available. We ended up loving the house and wanted to submit an offer. At the drop of a hat, while he was on vacation, Dre got on the phone with us for 45 minutes to talk about the house and start drafting up an offer. We continued communicating with him periodically through the rest of the afternoon, getting things squared away with the language. Fast forward to three days later, and we had an accepted offer! I can honestly say that I don't think we would have gotten our house if Dre hadn't willingly sacrificed part of his vacation time for us. He is not just a team player; he is a cheerleader and a coach too. He made sure we felt supported throughout the entire process, and it gave us such a positive experience as first-time homebuyers. His reputation truly precedes him; we're so grateful for the initial recommendation, and for the above-and-beyond service we received from Dre!”

“Carolyn is great to work with! She is fast to respond with showings arrangements and answers our many questions! My husband & I are in rental property management but this time we were looking for our own personal house. Carolyn has been showing us houses for a while and we finally decided that building our own "empty nester" house was the best for us. We found some land and Carolyn set up for us to view it & found out some information about what kind of buildings we could have on the property. She is friendly, helpful & professional. Thanks, Carolyn!”

“Mary Ellen is extremely knowledgeable in all aspects of real estate. She notices things we would never pick up on which is why we always ask for her to come with us any time we look at a home, even to open houses and she never hesitates. She is quick to respond and picks up quickly what we like and don’t like so she has a good idea of properties that we would be interested in. When looking at fixer-uppers she has a great knowledge base of how much repairs would be so we could preplan and has many connections within the community of reputable companies to work with. We worked with her when we were just starting out and moving back to our hometown, and then again when we wanted more space and she found us our forever home, and now again when we decided to get into buying real estate for rental properties and we will continue to work with her moving forward. We can’t say enough positive things about her, she is definitely the realtor to go with if you want thorough, friendly, and someone who will have your best interest at hand.”

“We cannot say enough good things about Andrew. He helped us buy our very first home in Mount Horeb in 2018, guided us through purchasing our second home in Blanchardville in 2023, and most recently sold our Mount Horeb house for us in 2026. Having worked with him through every stage of our homeownership journey, we can confidently say there is no better broker we could have hoped for. Andrew is extremely professional and exceptionally knowledgeable. When it came time to sell, he gave clear, practical recommendations on exactly what we needed to do to make our home as marketable as possible—and those recommendations truly paid off. He is hands-on, responsive, and genuinely invested in his clients’ success, making what can be a stressful process feel manageable and well-guided. Regardless of what company he is with, Andrew sets the standard for what a great realtor should be. That said, HomeTeam4U has been absolutely awesome throughout this transaction, and we are incredibly grateful for the support and expertise we received. We would recommend Andrew without hesitation to anyone looking to buy or sell a home.”

“I met Mr. Christian the same day my previous agent told me I needed to find a different agent. I requested a tour, and Christian scheduled a walkthrough the very same day. Within about two hours, I was touring my first property. Hiring Christian was one of the best decisions I made during my homebuying journey. I truly believe I would not have been able to close without his help. When my first lender did not approve my income, Christian quickly pivoted and connected me with other lending options. At one point, we even had two lenders reviewing my file to make sure every opportunity was explored. Christian ultimately placed me in the hands of a great mortgage company, and that experience turned out to be amazing as well. Throughout the entire process, Christian was proactive, supportive, and determined to help me succeed. I’m extremely grateful for his dedication and guidance.”

“Mallary went above and beyond helping us purchase our home! We were moving all the way from SC and she made this process so much easier. Driving to multiple houses in different areas for us and video calling giving us great tours of homes. The home we decided to buy had some issues with it and needed some repairs after the appraisal. Mallary went above and beyond buying things for our home using her own money to make sure we were able to get our dream home. She even offered to repaint the entire outside of the house on her own. She has a great work ethic, is extremely friendly, and very knowledgeable! I highly recommend her to everyone looking for a realtor!”

“We truly couldn’t have asked for a better realtor. Ryan stuck with us through months of searching and always patient, upbeat, and ready with new ideas and a great sense of humor!. Sometimes he knew what we’d love before we even saw it ourselves. He was so easy to work with by being flexible with showings, quick to respond and full of great local insight and contacts. We felt really taken care of every step of the way!”
