what is the best way to fund this deal

[Danyale Martinez]

A young lady I know father passed a few months back and left a 4bdrm, 3ba house that she wants to sell. It was put up for auction but she wants me to see if I can offer her more. The house is worth around $570K and it's also in excellent condition. I figured a good offer would be between $420K -$430K. How do I find an investor to help fund this deal? The  goal is for me to bring this deal to the table to an investor that can fund it and I get a percentage for finding the deal. Is the asking price fair? Am I going about this the right way? All advise is appreciated.
