All partners contributing equitable cash.1st property was almost turnkey - took a little paint and spit n polish and it was up and running.2nd property was a total rehab, then converted to rental.The way we decided to do it is that on the first property, the partner who is managing that property gets a percentage of monthly rent as a management fee.  

If the only tool you have is a hammer, then every problem looks like a nail. 

For example, if someone steps barefoot on a nail outside the property, what exactly happens?

For properties that are having non-emergency work done, especially if it is something for the convenience of the tenant, and the tenants are highly functional adults, I am fine with having the contractor make arrangements with the tenant - especially when there's not a "nail-down" time, like often happens with HVAC.

I know that I am just a few key points away from hurting myself or nailing this thing and no, I will not touch anyone else's money until I am well on my way and have a ton of experience.

You pretty much nailed it.

If the hinge pins are worn, the door can move a little bit left and right in the frame - imagine that the door is closed and you are pushing sideways on the door knob, pushing the knob towards the frame, as if it were a sliding door - that's the direction it would move in.To check the pins, you can either use a screwdriver to pry the hinge pin up a little and then pliers to remove it the rest of the way, or use a hammer and a nail to knock the hinge pin out of the hinge. 

If the numbers don't entice them though, it doesn't really matter how much trust you've built.If you really want to nail down how to pitch someone, don't think of it as a pitch, but think of it as a dialogue.

Never ever rely on a tenant to be responsible for anything, they will prove you wrong every single time.I would not trust a tenant to be responsible for a gold fish.You hit the nail on the head about responsibility.

@Jay HinrichsYou nailed it.
