Frequently asked questions
Do liens survive a tax sale in Kentucky?
Some do. A tax lien can extinguish a mortgage, but IRS liens have a redemption right, and municipal/code-enforcement liens, HOA super-priority amounts, and some assessments can ride through to the buyer. Always verify each parcel with the county and a title search before bidding.
What does '10.3% flagged' mean for Jefferson County?
Of the 7,923 Jefferson County tax-sale parcels DeedFlex checked, 10.3% turned up at least one recorded issue or hazard across 162,408 total checks. It is a research signal, not a verdict — a flag means 'look closer,' and a clean result still needs your own title work.
