Arlington Heights, Washington

Arlington Heights is an unincorporated community of about 2,700 people in Snohomish County, Washington. 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 5.9 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, Seattle, is about 43 miles away as the crow flies.

The book's checklist

  • Lower cost of livingEveryday prices run 11.1% above the U.S. average in the Seattle-Tacoma-Bellevue metro area.
  • More house for the moneyA typical home costs 5.9 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 townNo public schools inside the town. The nearest high school is Arlington High School, about 4 miles away.
  • A hospital close byCascade Valley Hospital in Arlington, about 3 miles away, has the nearest emergency room.
  • Within reach of a big citySeattle is about 43 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 Arlington Heights 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 9.9% since 2022. Everyday prices are the government's average for the Seattle-Tacoma-Bellevue metro area, not Arlington Heights alone. Check current listings before you budget.

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: Cascade Valley Hospital, Marysville, Seattle.

Snohomish County is in a metro area of 1 million people or more (USDA rural-urban code 1, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
