@Rahul Gupta I can only tell you my own experience but I'm currently in the process of buying a home through a different auction website (Hudson and Marshall) and yes they waited out the redemption period (which is 30 days in my state) and only after that, they listed the house for sale.

You will learn a ton from them and as you build a relationship they can potentially become a private lender or even partner with you on some deals down the road.Best way to find cash buyers is networking at local REI meetups, masterminds, Facebook groups etc,Also Realtors, title companies and closing attorneys, property management companies, auctions, Craigslist.

I’m not sure if any of the liens will survive 1st mortgage foreclosure auction in VA.

Purchased this property via an online auction on auction.com.

Wait and see how it goes at auction?

Do I attend auctions?

Auctioneers make a fortune as a business. 

I am about to do my first "pre-action tax deal" and I have some questions.
 After meeting the the owner Do I take them to a title company or Courthouse? 
Do I need to make a contract with them so they give me there ...

Well apparently there is some law that allows someone to bid again after the auction ended if they bid 10% more?

Try an auction house.
