Assuming there is no negotiation from this 25% number, what roles should I expect from him?  

Does my W2 taxable income have a role?

Look up @Jerryll Noorden, all his principles for dominating SEO apply.

It sounds cheesy, but the best way to prepare is to work with a friend or two and role play.

So it can be done.....I think as a GP you just have to define the role you want that works long distance.

Getting market domination can be really beneficial in self storage since it allows you to "fix" prices.

That said, if you end up with 50 doors over a long period of time, you can expect the average to be very close to this number when said and done.Locations and rent values play a role in the fluctuation of the "average" total costs.

Obviously some GC's have that PM/Sub/Laborers experience (as it was the case with our GC) but there is still a noticeable difference as they move more towards the "organizer" role (P.S. that is where the money is anyways...). 

Ensue the role of each person, from the COO to the PM is defined.

Were that the case then we should all be SOL thanks to the glorious ACH transfer.In reality, that is a small piece of the role, and it fits within the total package of stewardship, which is perhaps a better and more wholistic thing to expect of your manager.
