The rank is not the whole story. Erin also posted a 10.4% gain in the past year, on top of 31.1% growth over five years. The market that already led the county kept moving in the most recent data.

The Erin market in detail

Erin's $636,197 typical value stands about 36% above the Washington County median. The next tier of county peers in this data: Polk at $582,632, Richfield at $563,065, Wayne at $518,242, and Farmington at $496,122. The gap between first and second place — Erin over Polk — is about $53,600.

The growth profile is front-loaded toward the recent year. Five-year appreciation of 31.1% averages out to roughly 5.6% per year compounded, while the past twelve months alone delivered 10.4% — nearly double that average pace. Whether that continues is not something any dataset can promise.

There is no ZIP-level breakdown available for Erin in this data, so the town-level figure is the working benchmark.

Zillow’s typical-home-value estimate for Erin is $636,197, while homes that actually changed hands had a median price of $560,000 — a difference of -12%. 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.

Buying and selling in Erin

Buyers should recognize what a 10.4% one-year change means in dollars at this price point: the typical value rose by roughly $60,000 in a single year. Comparable Washington County alternatives at lower price points include Polk ($582,632) and Richfield ($563,065). Offers built on last year's comps will trail this market's recent movement.

Sellers in Erin are working from the strongest value position in the county — rank 1 of 15, with double-digit one-year appreciation behind them. The data supports confident pricing, but not unlimited pricing: the county median is still $468,207, and the pool of buyers above $600,000 is by definition thinner than at the median. Recent trends do not guarantee future results.

Life in Erin

Erin is kettle-and-moraine hill country with no downtown of its own — winding rural roads climb through woods and farm fields beneath the twin spires of the Basilica of Holy Hill, whose observation tower offers long views over the surrounding countryside. The Ice Age National Scenic Trail crosses the town near the basilica, and Erin Hills, the public golf course that hosted the 2017 U.S. Open and 2025 U.S. Women's Open, also lies within the town.
