Getting into wholesailing : Confused on the assignment strategy

[Ilario Sepulveda]

Now i know that once the owner is in default, the owner is most willing to sell their house to avoid foreclosure and risk getting nothing. And i think that is the best time to offer them a good deal on the house. Now i want to use the assignment strategy so i can hand it over to the cash buyer. But what if its past the default phase and into auction? Can i still use that strategy or is it too late and i would have to raise the funds and buy it? 

Also, Can you still use the assignment strategy when its in REO?

Yes im a newbie, someone help please!
