Who owns the homes in Washington Island?
Ownership reflects the most recent public assessor records (2026).
Of the roughly 1,035 homes in Washington Island, about 32.4% are held by owners with an out-of-state mailing address (above the Wisconsin average of 5.3%), and about 8.2% are titled to a company or LLC rather than a person (in line with the state average of 5.6%).
Company- and out-of-state-owned homes are usually the most willing to sell quickly for cash — they're managed as investments, not lived in.

Washington Island sits in a county where recorded mortgage data isn't reliable enough to report an accurate cash-sale share, so we've left that figure out rather than publish a number we can't stand behind.
For homeowners, the takeaway is that there's a real, active cash market for Washington Island houses — including as-is, inherited, and off-market sales that never hit the MLS. (HouseBuyerz is one of those cash buyers.)
