Mercer Island by the numbers

What Washington teaches — and to whom

Washington requires personal finance instruction, but folds it into another course rather than a class of its own — so how much a student actually gets depends heavily on the district and the teacher. Coverage like that varies enormously between districts, and it reaches no one who has already graduated.

LearnLife organises this the way the decisions actually arrive: Legal literacy — leases, contracts, employment rights and what a signature actually commits you to; Money — budgeting, credit, debt and taxes — the mechanics nobody is formally taught; Emotional regulation — the self-management that decides whether the other skills ever get used.

Where to start in Mercer Island

Learn the mortgage arithmetic first

Homes in Mercer Island run about 9.3× median household income — well past the 3× rule of thumb. That makes amortisation, escrow, PMI and the true cost of a rate difference the most valuable arithmetic a resident can learn before signing anything.

Shift from accumulating to drawing down

With a median age of 45.8, a large share of Mercer Island is closer to drawing on savings than building them. The skills that matter shift accordingly: sequencing withdrawals, understanding Medicare's enrolment windows, and getting beneficiary designations and a will actually filled in.
