Bank Auctions: Hidden Gems or Risky Traps?"

I've been coming across numerous videos claiming that you can buy homes, vehicles and even jwellery at significantly lower prices through bank auctions. The idea sounds tempting—getting a property or car below market value—but I'm curious about the reality of it. Has anyone here actually gone through the process? Were the deals as good as they seemed? I'm particularly interested in understanding the risks involved. Are there hidden costs, legal complications, or other challenges that might make these deals less attractive? If you've had any experience with bank auctions—good or bad—I’d love to hear your insights!
