The book's checklist

  • Lower cost of livingEveryday prices run 12.6% below the U.S. average in the parts of Illinois outside metro areas.
  • More house for the moneyA typical home costs 1.1 years of the typical household's income here. Across the U.S. it's 4.1.
  • A safer neighborhoodThe FBI has no 2025 figures for Sandoval itself. Many small towns are patrolled by the county sheriff, so call the sheriff's office and ask what calls they get most.
  • Schools in town3 public schools: 1 elementary, 1 middle and 1 high school.
  • A hospital close bySSM Health St. Mary's Hospital -Centralia in Centralia, about 6 miles away, has the nearest emergency room.
  • Within reach of a big citySt. Louis is about 61 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 Sandoval 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 26% since 2022. Everyday prices are the government's average for the parts of Illinois outside metro areas, not Sandoval 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: SSM Health St. Mary's Hospital -Centralia, St. Louis.

Marion County is outside any metro area, with 5,000 to 20,000 people in its towns, not next to a metro area (USDA rural-urban code 7, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
