Homes resold within 12 months of a prior sale. By city.

Ranked by number of flips, with the count shown for each city so you can weigh it — a city with only a handful of flips is context, not a statistically reliable rate. The King County figure above is the dependable measure.

A flip is an arms-length resale of the same home within 12 months of the prior arms-length sale — the definition ATTOM uses for its national home-flipping report. We screen to genuine market sales using King County’s own transaction codes (warranty-type deeds and a normal sale reason; excluding foreclosures, family and related-party transfers, and other non-market transactions) and sales of at least $10,000. “Gross price change” is the difference between the two sale prices — it is not profit or return on investment: it excludes renovation, holding, and transaction costs, which flippers typically estimate at 20–33% of a home’s after-repair value. These are estimates from public records, not appraisals (RCW 18.140). The King County figure is the reliable measure — ATTOM publishes flip rates only for counties with at least 50 flips, and King County clears that. The per-city counts below are shown with the number of flips so you can weigh them; a city with a handful of flips is context, not a statistically reliable rate.

What this means for buyers

A home that recently resold within a year is often a flip — cosmetic-rehab work done for a quick resale. That is not inherently bad, but it is a cue to look closely at permit history and the quality of recent work, since fast rehabs sometimes skip permits. County-wide flip activity also signals how competitive a market is for renovate-and-resell buyers.
