What to offer new investors?

[Collin Corrington]

I'm meeting with a new investor tomorrow.  He has the potential to add a couple of million to my working capital.  

He's been interested in getting to know my business and we've talked quite a few times.  My read is that he wants to tiptoe in before just handing me a ton of cash, which is expected. 

I just secured a pretty sweet flip. Under contract for $206,500 with a $340,000 ARV. My estimate is $50,000 in rehab.

With investors in the past, I've offered to split the first deal profits but on this deal, I think it will set an unrealistic expectation.  I'm estimating the total profit will be ~$63,000.  So paying out ~$30,000 for $260,000 invested in 4-5 months is a bit much to me.  

With seasoned investors, I normally offer a flat rate of 8-10%.

I'm curious how others have structured their first deals with new investors.
