The highest risk stuff is only a small percentage of investment. 

The Japanese are a big percentage of our tourist and have been coming here for years.

Thinking about offering time + material as investment and getting a percentage of the profit (15%) in return with a minimum matching the investment. 

On my first deal, I took a much smaller percentage of profit so that I could work to gain trust and demonstrate success.On a side note, if you are going to have truly silent investors, you are walking into the world of securities. 

You find a good house to flip, take it to him, he takes all risk, and you get a percentage and plenty of house flipping experience.

Even the best estimators add a percentage to their numbers to cover their butts.

Here's a simple analysis:Purchase price:$310,000 Rehab cost:$0 Rent:$3,200 Exp, vacancy, capital %:50%Loan rate:4.50%Loan term:30Down payment %:20%Down payment:$62,000 Loan amount:$248,000 P&I payment:$1,256.58 Expenses, vacancy, capital:$1,600 Net Operating Income:$1,600 monthly cash flow:$343.42 annual cash flow:$4,121.05 total investment:$62,000 Cash on cash return:6.65%Cap Rate6.19%Now, if you're going it with FHA and only 3.5% down, then it looks better percentage wise, but doesn't generate much cash flow:Purchase price:$310,000 Rehab cost:$0 Rent:$3,200 Exp, vacancy, capital %:50%Loan rate:4.50%Loan term:30Down payment %:3.50%Down payment:$10,850 Loan amount:$299,150 P&I payment:$1,515.75 Expenses, vacancy, capital:$1,600 Net Operating Income:$1,600 monthly cash flow:$84.25 annual cash flow:$1,011.01 total investment:$10,850 Cash on cash return:9.32%Cap Rate6.19%I wouldn't characterize that as:FHA is hindering my ability to make a profit monthly.

But the profits are here at double-digit percentages, for the crazy and brave.I have read many inspiring stories here and have always come away positively motivated. 

This will be our first time working together, so I am open to starting with me getting a lesser percentage at first.

For the Vacancy percentage I left it at 5% because he's already received 3 calls to come see the place and it seems like renting in that area is pretty vibrant.I think something to note that maybe J didn't add or maybe I did not specify was a potential 20-30K in repairs that need to occur.
