First timer's challenges in purchasing a Trustee Sale- Bay area

Hi,

I am a first time home buyer looking to find a decent home in a good neighborhood for a decent price in Bay area. I see a Trustee Sale listed in Redfin in Bay Area . Property is also a fixer upper . I see property is listed for 900K. I dont see an Auction Date or location or any other detail.

1) How do I find the Auction Date and location ?

2) Is the price listed in Redfin usually the Opening Bid for the property or can it be lower ?

3) What are the challenges in purchasing a Trustee sale property in Bay for a First timer's especially during COVID Times
