Sometimes new investors sit on the sidelines too long because they are unsure of themselves or they aren't confident in their numbers.

They’re young mover/shakers, and we have confidence that they’re going to continue to do well in life.

I'm estimating high, because bringing more cash to the table always helps the lender feel more confident in your deal. 

I would feel more confident if I knew someone that was doing this could give me some advise!!

And deal with payroll if you don't want to gamble with $0 salary.I spoken to my US accountant regarding the house flipping partnership, but he's not specializing in real estate, he's doing taxes for my other activities, so he couldn't give me a confident answer.

You should check out the "Confident Real Estate" channel on YouTube, and specifically the videos on "Getting Due Diligence Done Right" and "Seller Representations: Make the Seller Put Their Money Up."

I want to set myself up as early as possible to not 'work' I'm confident I can do such through real estate.

I also have one brand new 3BR that I closed on in June, too early to do ROI analysis but I'm confident it's going to be better.  

I think this has helped me a lot because I feel more confident in pricing when im analyzing a deal. 

For your first few I would suggest bringing your contractor with you for the walk through until you are able to judge it confidently yourself.
