The Winnebago County housing market in May 2026
Prices in Winnebago County are still climbing: the median sale price reached $220,000 in May 2026, 14.6% above a year earlier. Homes listed that month had a median asking price of $228,750, and sold for a median of $136 per square foot. The average sale closed at 101.0% of asking price and 50% of homes sold above list, so buyers are still bidding against each other.
There were 297 homes for sale at the end of May, down 16% from a year earlier, or 1.0 months of supply, a tight market. The typical home that sold had been listed for 13 days, 6 days longer than a year earlier. 65% of homes went under contract within two weeks of listing. Compared with May 2025, owners listed 8% fewer homes and sales were down 8%.
26% of listings had a price cut in May 2026 (0.7 points more than a year earlier), a moderate share.
For FSBO outreach, this means many Winnebago County owners can still sell on their own, so lead with pricing data and a net-proceeds comparison rather than an offer to list. The trend to watch: fewer homes for sale than a year ago and slower sales than last year.

When Winnebago County homeowners list
Listings follow a clear seasonal cycle in Winnebago County. Over the three years to May 2026, new listings peaked in June and August, with August running about 25% above the monthly average, and bottomed out in December, about 44% below it. Homes that sold in June had spent the least time on the market (a median of about 8 days), and those that sold in February the most (about 29 days).
Have your list, scripts and mail pieces ready by May, so you reach new FSBO owners in their first weeks. Sales are slowest around February, so FSBO owners still on the market then have often been waiting for months and tend to be the most open to help.

Working Winnebago County FSBO leads
- Use the 13-day mark. Half of the Winnebago County homes that sold in May 2026 had been listed 13 days or less, so an FSBO still for sale after that is likely stalling.
- Sell the upside. With 50% of homes selling above list, agents do better pitching wider exposure and competing offers than a discount.
- Time it. Put your heaviest outreach into June and August, when the most Winnebago County homes come to market, and ease off in December.
- Bring the numbers. On a $220,000 home, each 1% of commission is about $2,200, the money most FSBO owners are trying to keep, so a net-sheet comparison lands better than a pitch.
- Stay compliant and verify. Stop contacting any owner who says "no agents" or "no investors", confirm ownership and liens in Winnebago County records before an offer, and add skip tracing for records without a phone number.
