Frequently asked questions
Do liens survive a tax sale in New York?
Some do. A tax deed 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 '61.1% flagged' mean for Bronx County?
Of the 4,849 Bronx County tax-sale parcels DeedFlex checked, 61.1% turned up at least one recorded issue or hazard across 317,430 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.
