Can someone explain foreclosures?

[Fahadbin Alam]

Backstory: So I've read most of the BP books and I have 1 property right now and it's a BRRRR, but then I heard that the best deals are foreclosures and auctions.

1. I've thought that auctions are bad and I shouldn't touch them.

2. What is so difficult about foreclosures that people don't talk about them as much?

3. I was thinking of going to the court house steps and basically see if i can get a good deal within 20k, what do you think?
