On a related note, I would say that the biggest issue that small investors face is underbidding.

Quote from @Stuart Udis: The natural buyer of the entry level SF homes have limited cash and therefore the biggest obstacle they face is funds to close.

Atleast I don’t get FB ads from Norada.ODC is just a BP's pride & joy falling flat on his face, I don't think ODC is a scam.

The problem many face is being outbid by a few entrenched players who dominate local auctions or others willing to pay too much.

The challenge you'll face is that, even though this is fundamentally real estate, you're moving from the SFH retail world to evaluating institutional assets within asset classes that are likely less familiar.The first thing you'll notice is that the sponsors (who are the Trustees of the trust and could also be thought of as the general partner of the deal) will issue a PPM (private placement memorandum) that is a 300-500 page document.

If it is staring you in the face, I would address it sooner rather than later. 

More often than not, I'm speaking to someone who isn't in a rush to fund a deal so time is typically available to have a handful of calls, perhaps meet for coffee although a face-to-face is nice but not a requirement.     

The first question you face is whether you “have to” meet this capital call.

Being able to meet face to face is always better.

I already have a couple potential deals, but the biggest hurdle I'll face is finding a private money lender who's willing to lend to someone with minimal experience.
