wholesaling a REO for more than double

[Curtis Brown]

Is it possible to wholesale a REO property for more than double of what you have it under contract for with out doing any fixing as long as there is enough equity.

example:
1) Put REO under contract for 30k.
2) House Assessed value is 110k
3) I want to sell it for 70k.
Is this possible, or does it depend on the buyers lender.
