The town of Ottawa prices near the top of an already high-priced county. Its typical home value of $647,772 as of April 30, 2026 ranks 7 of 27 municipalities in Waukesha County, where the median municipality is valued at $534,102.
Growth is the standout figure here. Values are up 32.7% over five years and 8.7% in the past year — the recent pace is running ahead of the five-year average of roughly 5.8% per year compounded.
Measured against the seven-county region's median municipality value of $455,834, Ottawa carries a premium of about 42%.
At $647,772, Ottawa sits about $113,700 — roughly 21% — above the Waukesha County median. Its peer group frames the position: Elm Grove ($697,367) and Hartland ($669,294) price above it, while Genesee ($613,231) and Lisbon ($578,057) price below.
ZIP 53118 shows a typical value of $607,562, about $40,000 under the town-level figure — a reminder that ZIP and municipal boundaries do not line up exactly, so both numbers are worth checking when valuing a specific property.
The five-year gain of 32.7% is one of the larger increases you will see attached to a market already priced above $600,000. The one-year change of 8.7% shows that appreciation had not flattened as of April 2026, though no trend guarantees future results.

Over the 12 months ending June 2026, 47 single-family homes sold in Ottawa, Wisconsin in arms-length transactions, at a median price of $565,000. Half of those sales fell between $408,000 and $915,000.

Zillow’s typical-home-value estimate for Ottawa is $647,772, while homes that actually changed hands had a median price of $565,000 — a difference of -12.8%. 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 targeting Ottawa are competing in a market that has appreciated 32.7% in five years, so waiting has carried a measurable cost in this data. The nearby alternatives run in both directions: Lisbon at $578,057 and Genesee at $613,231 offer lower entry points, while Hartland and Elm Grove price higher. Budget against the town figure of $647,772 rather than the lower ZIP 53118 number if the property is inside town limits.
Sellers hold a strong data position: a top-seven county ranking, an 8.7% one-year gain, and a 21% premium over the county median. That said, pricing should be built from current comparables, not from extrapolating the five-year trend forward — past appreciation is a record, not a promise.
The town of Ottawa is rural countryside at the edge of the Kettle Moraine State Forest's Southern Unit, and the Ottawa Lake Recreation Area with its year-round campground, the Scuppernong Springs Nature Trail, and a stretch of the Ice Age National Scenic Trail all lie within its borders.
