I would put each investment into it's own LLC with shares divided based on either $ amount input or just make him a non-voting member or less 50% owner of the shares so you can take charge.

Currently I am allowed to rent 7 of my units which I am in the process of doing (3 rented and 3 applicants being processed).  

The other option that you can use for (Flooring, Lights, Appliances etc.) is charge on a HD or Lowes Card if you have one.

I think it's a fantastically made product with a great, easy-to-use, customizable interface.As for other applications, what are the business problems you currently deal with?

Their are two kinds of metal pipes,,,those that leak,,,and those that are gonna leak (and plug up).I have seen drain rotor rooter people charge more to rooter a drain than it would have cost to cut it off and put a new plastic one on that wont plug up.but under slabs its 90% labor 10 % materials,,,and never never tunnel under one to fix anything,,,thats way past crazy. 

My lease allows me to charge them for it, but man, I guess people who have no skin in the game are just careless.

Never let tenant damage things without charging them.  

Use the following guidelines for figuring the applicable percentage for property with two or more elements.

Water,Sewer, Garbage are charged to the tenant in the lot rent price.

Could have 'Barney Fife' in charge of that $300/mo HOA.
