I outlined my strategy with these percentages exactly. 

What percentage (1, 2, etc) do you use for closing cost when you analyze properties.  

(all his risk) He is paying the builder (another brother) just like anyone pays a GC.When it's all said and done, they think they can sell the home for a profit, but they are not sure how to split up the profits, should the ratio be based on the percentages for example 23% to the father-in-law, and then 77% to him?

If you're wanting to take a significant percentage with no cash on the line and not much labor to be contributed, its not a deal for me. 

You might have a better time if you put down a larger percentage. 

And add a percentage to your income.

What percentage qualifies as "high booking acceptance rate", "high average rating/reviews", "low cancellation rates"?

IRR is the percentage expression if that cashflow.
