If I found a project that requires $100k to get done and it would make 1million in a year, what percentage would you share with the investor?

Only a tiny percentage will refuse and show up in court. 

Hi Jamal, It may be just be me but I would double the vacancy and repairs & Maintenance percentage just to be safe, it will help you in the long run to do that now.

We were talking about a small finders fee, a small percentage and then a management fee, so perhaps you thought I was taking 50/50 which is not the case here. 

Is there a percentage rule of thumb that I should be applying to my property analysis to get a rough figure of yearly capex and maintenance expenditures?

Make sure you are putting away a percentage for maintenance expenses, vacancy, capex, and maybe future management expense.

How do I figure my worth as a percentage in this partnership and make sure I get a fair deal during the next 10 years and when we eventually sell?

Do they cap out at a certain price or is the loan cost all relative to the amount finances (i.e. a percentage)? 

The highs and lows of that rate vary by only a few percentages off that.

If I live in it for only one year and then sell it – would 125,000 be tax free (this is what I read somewhere – that if you live in it for a percentage of the 2 years then you get that percentage of the 250,000).
