How we ranked them
Ranked by median value of owner-occupied homes as reported by owners (ACS 5-year estimates, 2020–2024). Published medians are capped at $2,000,000. ZIP codes need at least 1,000 residents to be ranked; 21 of 23 qualify.
Which of these to mail, and why
Home value tracks what owners spend on the house itself: renovations, landscaping, pest control, security, interior design. Pair it with the homeowner share so the mailer reaches owners, not tenants.
