Title insurance + possession for an auction property

[Nehel Khanani]

Newbie Questions (pardon my ignorance please!)

1. I'm looking to buy a property at a live auction (in CA) or a rental property via an online auction (auction.com) but not sure how the Title insurance works for auction property. DO i contact the title company beforehand for each property I plan to bid on (and want to purchase insurance for)? Seems like that may get expensive! With trustee sales I'm worried there may be heirs that we don't know about or unpaid taxes etc. What do you guys do/recommend? 

2. What does it mean when it says "buyer is responsible for taking possession" and "buyer will be issued a warranty deed of sale"? For the former, is that just referring to the potential need for an eviction? Is a warranty deed of sale a title of ownership? 

Thanks all

And if anyone is based in california bay area, would love to meet up!
