Trustee sale versus tax sale
A deed-of-trust trustee sale and a property-tax foreclosure are different proceedings, with different notices and different places to read the record.
Trustee sale
A trustee sale follows a power of sale in a deed of trust. The lender or servicer appoints a trustee or substitute trustee. The notice of sale is filed with the county clerk and posted for the statutory period. The auction is on the first-Tuesday calendar described in §51.002.
This site tracks those clerk postings. It does not track every lawsuit.
Tax sale
A property-tax foreclosure is a court proceeding. The notice, the officer who conducts the sale, and any right of redemption come from the Tax Code and the judgment, not from a deed-of-trust notice. Tax-sale lists are often published by the law firm representing the taxing units.
Do not treat a trustee-sale row as a tax-sale row. If you need the tax proceeding, read the judgment and the constable or sheriff's notice.
