Year-2 50% rate applies only to homestead, agricultural, and mineral property; other property is capped at 25% (Tex. Tax Code §34.21). Redemption: 2 years from the date the purchaser's deed is filed for record for residence homestead, agricultural land, and mineral interests; 180 days from deed recording for all other property (§34.21) Sales: Sheriff/constable sales on the first Tuesday of every month Governing law: Texas Tax Code Chapter 33 (Delinquency) and Chapter 34 (Tax Sales and Redemption), esp. §§34.01, 34.21.
