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

Lake Koshkonong’s rolling three-month data through May 2026 shows mixed year-over-year movement. Typical home values are down compared with a year ago, dropping about 11 percent even as the median list price has climbed roughly 24 percent. At the same time, homes sold are up year over year, indicating that buyers are still active despite the pricing shifts.

Looking at the latest rolling period, inventory is tight and leaning toward sellers. Months of supply has fallen to around 1.4 months, down about half from a year ago, which aligns with the current seller’s market reading. Active listings have slipped nearly 12 percent year over year, while new listings have inched higher, suggesting fresh options are appearing but not fast enough to change the overall balance.

Conditions for timing a move are being shaped by how quickly homes change hands and how close they sell to asking price. The median days on market in this rolling window is 39 days, far lower than a year ago, and the average sale-to-list ratio is just under 100 percent, with more than one in five homes selling above list. With only 14 active listings and 11 pending sales, both buyers and sellers in Lake Koshkonong can benefit from Agent Pronto’s help in finding an agent who understands these dynamics and can guide their next steps.



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.
