.- The TL states that those are technically the team's leads and I will owe the 20% if they convert within the year since I was given training (which I was not), lender referal (which was forced on me by the TL even though I work with my own lenders for my clients).Is the above statement true/legal/valid?

Will there be more issues come about at an inspection?

The reality is there are many issues with ADUs as an investments and the poor valuation is just one of them.  

Your main concern should be whether these bedrooms and bathrooms on the lower level are legal and have the proper egress require for fire code and livability.

there are several posts on here about capital calls. without more information it is tough to respond but typically a capital call is because the offering is having issues with cash flow - whether it is because a loan is becoming due or some other reason - that is the primary reason - needing an influx of cash. can you provide more details?

So far, I've rated Evergreen and FCI lowest based on a number of reviews on different platforms that have consistent negative reviews mentioning certain specific issues that I find concerning (this is after accounting for the inevitable disgruntled customer/borrower who gets unjustifiably upset).Are you able to share any of your information?  

You could easily niche into that via even just the legal realm and would probably never have to step outside of it.

Obviously some potential issues with the lender, but how often do these deals really happen?
