Who should choose Seattle

Families on a budget who want good schools without coastal price tags

Seattle fits families on a budget who want good schools without coastal price tags. Lower typical rent ($2,030/month) plus stronger school scores (A) is the combination that actually changes a decade of life, not just a year of housing.

That pairing is for people who will work hard and then actually use the evenings.
