The typical home in Fontana-on-Geneva Lake, Wisconsin is worth about $670,816 as of 2026-07-03, up 3.9% over the past year and up 36.3% over five years. Source: Zillow Home Value Index, compiled by Sawar Homes.
Two numbers frame Fontana-on-Geneva Lake's market: a 36.3% five-year gain, and a 3.9% one-year gain. The typical home value reached $670,816 as of April 30, 2026 — strong long-run appreciation, with a clearly slower most recent year.
The village ranks 2 of 21 Walworth County municipalities by typical value, behind only the Town of Linn ($760,357). Its premium over the county median of $446,069 comes to $224,747, or about 50%, and it sits roughly 47% above the seven-county regional median of $455,834.
Nearby peers by value include La Grange ($632,238), Williams Bay ($545,006), and Troy ($531,440).
The five-year figure of 36.3% averages out to roughly 6.4% per year compounded. The past twelve months came in at 3.9% — the slowest pace relative to trend among the figures in Fontana's own data. One soft year is not a trend reversal, and neither the long-run gains nor the recent cooling guarantees what comes next.
Positionally, Fontana sits nearly $90,000 below Linn and about $39,000 above La Grange. The drop to Williams Bay ($545,006) is steeper — around $126,000 — so within the Geneva Lake area the data shows three distinct pricing tiers rather than one continuous band. Rent and yield figures are not available for this market in the current dataset.

Over the 12 months ending June 2026, 131 single-family homes sold in Fontana-on-Geneva Lake, Wisconsin in arms-length transactions, at a median price of $695,042. Half of those sales fell between $495,725 and $976,050. 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 Fontana-on-Geneva Lake is $670,816, while homes that actually changed hands had a median price of $695,042 — a difference of +3.6%. 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 have more documented negotiating context here than in most nearby markets: the 3.9% one-year change trails the roughly 6.4% annual average of the past five years, which means recent comps reflect a cooler market than the five-year headline suggests. Cross-shopping is well defined too — La Grange at $632,238 and Williams Bay at $545,006 bracket meaningfully different budgets within the same county.
Sellers retain a second-place county rank and a typical value 50% above the Walworth County median, both of which support premium pricing relative to the county at large. The honest read of the data is that momentum slowed in the latest year, so comps from the last twelve months are the sturdier pricing anchor. A 36.3% five-year gain is a record of the past, not a projection.
Fontana wraps around the west end of Geneva Lake, where the village beach, lakefront parks and the Abbey Resort's marina line the shore. The public shore path that circles Geneva Lake passes along the waterfront, and Reid Park and the Duck Pond Recreation Area add green space a few blocks uphill from the water.
