San Patricio County, TX tax sales

County offices

County notes

• •The elected Tax Assessor-Collector is Marcela Thormaehlen. The main office is at 1301 E. Sinton Street, Suite C, Sinton, with substations in Aransas Pass (225 W. Wheeler), Mathis (600 N. Frio Street) and Portland (900 Austin St.). Hours are Monday through Friday, 8:00am to 4:30pm.
• •The Sheriff conducts the sale. Sheriff Oscar Rivera signs the bidder letter on the auction site. The Sheriff's Office is at 300 North Rachal, Sinton, TX 78387, phone 361-364-9600.
• •The bidder certificate and the auction account are two separate steps. The Tax Assessor-Collector issues the certified Written Statement confirming no delinquent taxes are owed in the county, and the Sheriff's Office must have it on file before a deed will issue.
• •Deposits use Realauction's shared escrow. A single deposit can be allocated across multiple Texas county sites that use the same login, but a bidder must sign in to the San Patricio site before allocating funds to it.
• •Sale frequency is irregular. Sales appear on the calendar only when properties are posted, so several first Tuesdays pass with no sale.

Texas rules

Redemption

The redemption clock runs from the date the purchaser's deed is filed for record, not from the sale date. Property that was the owner's residence homestead or was land designated for agricultural use when the suit or the warrant application was filed, and any mineral interest, may be redeemed on or before the second anniversary of that filing. Every other property may be redeemed only through the 180th day after the deed is filed. When a parcel is struck off to a taxing unit instead, the period runs from the date the taxing unit's deed is filed for record. The former owner has no right to use, possess, or collect rent from the property while the redemption right runs, and the right of redemption cannot be sold or transferred: any instrument purporting to transfer it is void.Texas Tax Code 34.21 - Right of redemptionTex.

Deed deposit

The Tax Code sets no statewide deposit and no buyer premium. Section 34.01 directs the officer to conduct the sale the way similar property is sold under execution, so payment terms are set locally by the officer who runs the sale. Most Texas counties collect the full bid in cash or by cashier's check on the day of the sale. Confirm the terms with the county before you bid.Texas Tax Code 34.01 - Sale of propertyTex.

Homestead deeds

Texas sets no separate opening bid for a homestead. What changes on a homestead parcel is the exit: a residence homestead, land designated for agricultural use when the suit or warrant application was filed, and a mineral interest all carry a two-year redemption right instead of 180 days, and the premium the owner pays can reach 50 percent in the second year. Price a homestead parcel for that longer clock.Texas Tax Code 34.21 - Right of redemptionTex. Tax Code 34.21Verified Jul 25, 2026

Surplus proceeds

The officer pays any excess proceeds to the clerk of the court that issued the order of sale. The clerk holds the excess for two years after the sale and notifies the former owner when the amount exceeds $25. A claim must be filed before the second anniversary of the sale. The court pays established claims in statutory priority: a purchaser at a sale later adjudged void, taxing units for post-judgment or omitted taxes, other lienholders, taxing units for unsatisfied judgment amounts, and then the former owner. Anything unclaimed is distributed to the taxing units.Texas Tax Code 34.03 - Disposition of excess proceedsTex. Tax Code 34.03Verified Jul 25, 2026

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
