Lake Wisconsin, Wisconsin

Lake Wisconsin is an unincorporated community of about 5,400 people in Columbia County, Wisconsin. It has no city government of its own: local services come from the county, or in some states from the town or township. A typical home costs about 3.6 years of the typical household's income, compared with 4.1 across the U.S. The nearest metro area of about a million people or more, Milwaukee, is about 85 miles away as the crow flies.

The book's checklist

  • Lower cost of livingEveryday prices run 2.7% below the U.S. average in the Madison metro area.
  • More house for the moneyA typical home costs 3.6 years of the typical household's income here. Across the U.S. it's 4.1.
  • A safer neighborhoodThe FBI doesn't publish crime figures for unincorporated communities. Call the county sheriff's office (or the town or township police, where there is one) and ask what calls they get most.
  • Schools in town1 public school. No public high school in town: the nearest is Lodi High, about 4 miles away.
  • A hospital close bySauk Prairie Hospital in Prairie Du Sac, about 9 miles away, has the nearest emergency room.
  • Within reach of a big cityMilwaukee is about 85 miles away as the crow flies. The book suggests staying within about 60 miles if you'll miss big-city sports, concerts and theater.

A check means Lake Wisconsin meets the rule of thumb from Frank and Dave's book. An empty box isn't a deal breaker: it's something to weigh for your family. A question mark means there isn't enough data.

Home values and rents are what households told the Census Bureau across 2020 to 2024, so they trail today's market: county prices have moved up 25% since 2022. Everyday prices are the government's average for the Madison metro area, not Lake Wisconsin alone. Check current listings before you budget.

Getting around

Straight-line miles. The road is always longer, and as the book says, an interstate at 70 is a different trip from a farm road at 45. Check the real drive: Sauk Prairie Hospital, Madison, Milwaukee.

Columbia County is in a metro area of 250,000 to 1 million people (USDA rural-urban code 2, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
