ROI for private lender

[Joseph Billow]

I have the possibility for a loan from a private investor for my next investment home purchase. I haven't accepted private money before, nor has my potential investor loaned money for such an investment before. I need help in understanding what is a reasonable or "standard" return the investor can expect and how the loan should be structured.  My intention for the property is to buy, rehab, rent and refinance. I would pay the investor back in full plus their "return" when I refinance. So if things work as planned the loan would be fairly short term. Any advise or info would be appreciated.
