Trying to educate myself on buying a TX property with back taxes

[Suzanne Johnston]

There is a house that was just brought to my attention by a coworker where the owner had died and it has now been vacant for 3 years. I’ve looked and taxes are owed for these years. I know the county eventually holds tax sales, but is there another way to approach buying a property like this? I’m not exactly sure where to start. I’m guessing the property was owned free and clear, but maybe Covid has delayed a foreclosure?
