Help me understand how to proceed on sale

[Chris H]

I have a buyer that wishes me to find her a home. She as seen my rentals and knows that I can find good deals. She has good credit and is a very reliable person. I am wanting to pick up a foreclosure for 80% of asking price and resell it to her for the asking price (pocketing the difference of course), however, I am not sure of the best, cleanest and most efficient way of doing this. Should I borrow using hard money, should I just get the home under contract and somehow sell it to her without really buying it myself??? Can anyone help, I desperately want to get my first non-rental deal done successfully.
