The typical home in Williams Bay, Wisconsin is worth about $545,006 as of 2026-07-03, up 4.0% over the past year and up 47.4% over five years. Source: Zillow Home Value Index, compiled by Sawar Homes.
Five-year growth of 47.4% defines Williams Bay's market data. The typical home value reached $545,006 as of April 30, 2026 — meaning values grew nearly half again over five years, one of the steepest climbs a market can post in that window.
The most recent year tells a different story: 4.0% growth. That is positive, but it is well under the roughly 9.5-points-per-year simple average implied by the five-year figure. The run has cooled; it has not reversed.
Williams Bay ranks 4 of 21 Walworth County municipalities by typical value, carrying a $98,937 premium — about 22% — over the county median of $446,069. It also sits roughly 20% above the seven-county regional median of $455,834.
Among its listed peers, Williams Bay is the priciest: Troy sits at $531,440, Spring Prairie at $529,496, Bloomfield at $515,928, and Geneva town at $483,178. The top of that group is compressed — Williams Bay, Troy, and Spring Prairie span less than $16,000 — while Geneva trails by more than $60,000.
ZIP 53191 shows a typical value of $533,445, about $11,600 under the village-wide figure. As always, ZIP and municipal boundaries capture different footprints, so treat the gap as a sampling difference rather than a discount.
The trajectory question is the one buyers and sellers here should sit with. A market that compounded 47.4% in five years and then posted 4.0% in the trailing year has clearly changed gears. Nothing in this data says which gear comes next — a snapshot cannot predict, and past growth does not guarantee future results.

Over the 12 months ending June 2026, 90 single-family homes sold in Williams Bay, Wisconsin in arms-length transactions, at a median price of $539,108. Half of those sales fell between $400,175 and $678,000. Source: Wisconsin Department of Revenue real estate transfer returns, compiled by Sawar Homes — every recorded sale, including for-sale-by-owner and builder-direct transactions that never appear in the MLS.
Zillow’s typical-home-value estimate for Williams Bay is $545,006, while homes that actually changed hands had a median price of $539,108 — a difference of -1.1%. These measure different things, and neither is wrong: the index estimates the value of every home whether or not it sold, while the sale figure reflects only the homes that changed hands, which usually skew toward the more affordable end of the market.
Buyers face a market that already made its big move: the six-figure premium over the Walworth County median ($98,937) is largely the product of the last five years. The consolation in the data is the 4.0% recent pace — the cost of taking time to shop rose far more slowly over the past year than the five-year figure would suggest. At these price points, comparing against Troy ($531,440) and Spring Prairie ($529,496) is a natural cross-check.
Sellers who bought five years ago are sitting on the strongest paper appreciation in this peer group's recent history — 47.4%. The pricing risk is anchoring to that momentum: the market's trailing-year pace is 4.0%, and buyers can see nearby alternatives priced within a few percent. Pricing to current comparables, rather than extrapolating the five-year run, is what the numbers support. No outcome is guaranteed.
Williams Bay occupies the north shore of Geneva Lake, where Edgewater Park's lakefront lawn, the municipal beach and a stretch of the Geneva Lake Shore Path meet the water. The restored 1897 Yerkes Observatory anchors one side of the village with tours and gardens, while the Kishwauketoe Nature Conservancy adds more than 200 acres of boardwalked wetland and prairie near the lakefront. Highway 67 rounds the bay to neighboring Fontana, and Highway 50 runs east along the lake toward Lake Geneva.
