Pursuant to Section 3712 of the Revenue and Taxation Code, tax deeds convey title to the purchaser free of all prior encumbrances (mortgage liens, judgment creditors, etc.) of any kind EXCEPT liens specified by Section 3712, Lis Pendens actions and any Federal Internal Revenue Service (IRS) liens that, pursuant to provisions of federal law, are not discharged by the sale, even though the Tax Collector has provided proper notice to the Internal Revenue Service before that date. (IRS liens will be announced at the time of the tax sale.) You will need to research liens on the properties to determine if the properties are encumbered in any way. Payment of the bid amount at a tax-defaulted public auction may or may not discharge these types of obligations.
