Lead Types in King County
Pre-Foreclosure
Homeowners in King County served with a foreclosure complaint who still hold the deed. This is the window before the auction, while an equity sale is still on the table. Owner and property data from public records.
Divorce
Divorcing owners in King County with real property to divide. The home is usually the largest shared asset and has to be sold or bought out, often on the court's timeline. Owner and property data from public records.
Probate
Open probate cases in King County with real property in the estate. Heirs often look to sell rather than manage, maintain, or carry the taxes on an inherited home. Owner and property data from public records.
Guardianship
Court-appointed guardianship cases in King County where the guardian has authority to sell the real property of an incapacitated owner. Owner and property data from public records.
Pre-Probate
King County's recently deceased homeowners whose estate has not yet entered probate: the period after a death and before an estate is opened. Reach the family before a probate attorney is retained and before the home is listed. Owner and property data from public records.
About King County
King County ranks among Washington’s biggest counties by population, and the U.S. Census numbers show why it matters for deal flow: the county’s roughly 988,300 housing units run 56% owner-occupied against a median value of $811,200, the kind of settled homeownership base that reliably produces distressed-property filings. Our off-market leads from public court records surface motivated sellers across King County from the day of filing, while the owner is still deciding what to do.
King County at a glance
King County, Washington, is home to 2,262,713 people in 988,330 housing units, with the county seat in Seattle. 56% of its homes are owner-occupied and the median home value is $811K.
What makes the King County market different
- Housing in King County is tight: only 6% of units are vacant, against 10% nationally. Low vacancy usually means a renovated house finds a buyer or a tenant quickly.
- Only 30% of owner-occupied homes in King County are owned free and clear (U.S.: 39%). More owners carry a loan, so check the estimated equity on each lead before you make an offer.
- King County is younger than the country as a whole: 14% of residents are 65 or older (U.S.: 17%). Younger owners are more likely to carry a mortgage and to move for work or family.
- HUD sets the fair market rent for a 3-bedroom home for the Seattle-Tacoma-Bellevue, WA area at $3,324 a month, against a median home value of $811K in King County. Set those two side by side to judge whether a buy-and-hold rental pencils out before you make an offer.
- Permits were issued for 8,505 new housing units in King County in 2025, down 20% from 2024. With less new supply coming, existing homes carry more of the market.
