How sales work in Harris County
Texas sets the sale rules statewide, so they are the same in every county:
- Mortgage foreclosures are usually nonjudicial trustee sales. Notice must be posted at the courthouse and filed with the county clerk at least 21 days before the sale (Property Code 51.002). Texas foreclosure guide
- Sales are held on the first Tuesday of the month between 10 a.m. and 4 p.m. at the courthouse or an area the commissioners court designates, or online if the county authorizes it.
- Tax sales follow a court judgment or tax warrant and are run by the sheriff or a constable. Homestead and ag property can be redeemed for 2 years, other property for 180 days (Tax Code 34.21). Texas tax sale guide
