Starting a New Partnership (Complicated Terms) Need Advice

[Robert S.]

This is my first post so I will be a bit over indulgent in the details. However, I am hoping that a few more experienced members can PM me to provide some advice.

Background: I am a corporate lawyer that started purchasing investment properties a few years back. I personally own 11 units and have developed a good business model through blood, sweat, tears and trial and error. As I have progressed, a family member who is an accountant at a large out of state firm reached out and told me that he would like to join me in some investments. Our personalities greatly differ with he being more of the financial analysis/accounting type and me being more of the deal with tenants and find the deal type. After some discussion, we agreed to try (2) investments. I found 2 deals that I received via networking and we ended up getting both properties for a price that was way below market value. I already have both units rented and since he is out of state, I manage the renters, renovations and day to day operations. We are at the point where we need to decide equity splits and a fair revenue breakdown going forward. 

He has drafted a spreadsheet that analyzes various relevant factors in determining equity and I dealt with churning out the Operating Agreement for the partnership. We both would like a third party to analyze the spreadsheet as this is new territory for us and we would like a third party to review factors we observed when finalizing the equity in each unit. I also would like to run some deal points by some more experienced members to see if terms such as "deal finders fee" etc. are being given proper weight. I will gladly share the spreadsheet with anyone who PM's me to discuss my questions. We would both like to make sure that each person is being treated fairly and getting proper equity when analyzing the relevant factors.
