The book's checklist

  • Lower cost of livingEveryday prices run 1% above the U.S. average in the Charleston-North Charleston metro area.
  • More house for the moneyA typical home costs 7.9 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 Seabrook Island 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 townNo public schools inside the town. The nearest high school is St. Johns High, about 11 miles away.
  • A hospital close byBon Secours-St. Francis Xavier Hospital in Charleston, about 18 miles away, has the nearest emergency room.
  • Within reach of a big cityJacksonville is about 178 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 Seabrook Island 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.

What kind of town

Tourist town. About 44% of homes are vacation or seasonal homes, a sign of a visitor economy. More restaurants, shops and weekend events than locals alone could support, with the small-town basics intact.

The book sorts small towns into six types. These labels come only from the numbers; take the quiz to see which type fits your family.

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 Charleston-North Charleston metro area, not Seabrook Island alone. Check current listings before you budget.

Charleston 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).
