And this depends on who arrange financing if any.

I'd be happy to arrange it.

I’m newly licensed so I’m looking for a broker that I can arrange a mutually beneficial arrangement with for me to do deals under.

Loans do tend not to happen by accident under tax law - the courts like to see notes, collateral, and a list of other "bank-like" arrangements for a vague transaction to be viewed as a loan.Contribution via a personal credit card buying something for the IRA.....muddies things up a bit. 

Is an LLC overkill for this type of arrangement? 

Everything that remotely smells like advertising is deleted in the forums :-( thus the paid marketplace area (hint).Since BP doesn't have non-US cities to choose when hosting and arranging local events, some people (wink) might have to choose a US location but be sure to add local keywords to their headlines and content.

Check out Guardian Water & Power, their smart (water) meters are in the $150/ea range (not including installation, but they'll arrange for that too) and do not require any involvement by the local water utility.  

So, if we agree that a fair mgmt fee would be $75 per month how does this translate into a partnership arrangement?

I will arrange my schedule this month.

If they are going to be late, they need to make payment arrangements before the 5th and there is a late fee.
