I wonder if we will see a similar crash in Single Family - I'm skeptical for a number of reasons, prime among them the relatively stable debt and huge percentage of homes owned free and clear. 

A percentage are just crooks, another percentage incompetent, some new & ignorant, etc.The best way to screen PMCs is to ask a LOT of questions about how they perform their services.

You could look at charging interest plus getting a percentage of the profits, which boosts your potential earnings.

Unless the withdrawing member's ownership interest was sold, it shall be transferred to the remaining Member(s) in the Company at the same ownership interest percentage ratio that exists at the time of withdrawal.

They use a percentage when maintenance/cap ex is not primarily a function of rent. 

My struggle has been on the percentage for each partner since they are bringing 80-90% of the cash (for purchase and renovations) and I am finding the deal, putting the sweat and selling it.

My team and I are putting together plans on how and what we should do but I'm already thinking ahead of everyone's role and percentage of ownership in this potential partnership.

If I was involved, I would want to give you fair market value for the land, and only give up a small percentage after that, because the builder will be doing the heavy lifting on this project. 

If you have multiple people on the company, you ideally want the person with the highest credit score to have the most ownership percentages. 

Looking for help on what percentages should be for expenses at this scale and any creative financing options?
