difference between tax deed auctions and sherrif sales

[Trent Herbert]

Hi BP, I'm new to this game and had a question about tax sales. What is the difference (if any) between a sherrif sale and a tax deed sale? are they both considered foreclosures? I've been reading up on tax sale auctions that are conducted by county constables according to precincts, but then I heard about sherrif sales. My instinct tells me they're pretty much the same thing, just one is conducted by county sherrifs, the other by county constables? Do Sherrif sales include tax sales and other foreclosure types? I appologize if these seem like basic questions, I'm a newbie. I appreciate any feeback/advice you fine people can give me. Thanks!
